Hippo Mills 3 phase diesel generator

Hippo mills have developed a new 3 phase diesel generator. This generator can drive 3 phase electric motors up to about 9 kW. This generator has one 3-phase plug and 3 single-phase plugs. The diesel engine on the generator is water cooled.

 

The HDD detroyer: Hippo Mills new test results

We here at Hippo Mills do all kinds of tests on our mills. This week we milled a computer hard drive of a client. The Hippo Hammer mill destroyed the hard disk drive in a matter of seconds. The hippo mill can be used as an HDD destroyer. See below the photos we took of the output.

Hippo Hammer Mill Kickstarter

 

Features and Benefits of the ABC Hansen “Kick-Starter”:

Electric motors can draw up to 4 times the rated amps of the motor on start-up. This means that a 55kW motor can require up to 440 amps on start-up. It also means that the peak electricity demand would be set at this amperage, resulting in large peak demand charges, often more than a whole month’s consumption.

This is the case even with VFD’s and soft starts and while the amperage may be only somewhat lower, the cost of soft starters for large motors is also high. The other alternative is to install a capacitor bank which again is very expensive and only partly successful if not at full large motor capacity. The other problem is that capacitors would take up the load of the all motors in the factory, therefore when the large motor is started while the other motors is running, it may very quickly run out of capacity.

It is also useful where a factory power supply is limited and the main breaker goes into overcapacity and trips whenever the large motor is started.

 

ABC Hansen manufactures a “Kick Starter” to get the large motor, not under load, in motion, reducing the time it requires high amperage and also limiting the start-up amperage demand.

 

The system may be supplied at a low cost with a manual application or at slightly higher cost with fully automated application.

Where a more sophisticated system is required, it would involve the “kick-starter” with soft start or VFD where the large motor is simply started as before.

Push the Kick Start mechanism firmly towards the main drive motor. While the mechanism is moving forward the Kick Start motor will energise(rotate).

Make sure to firmly engage the drive mechanism and apply great force so that the wheels do not slip.

After 10 seconds the soft starter will energize and the main drive motor will start rotating. At this moment the Kick Start will stop rotating, now you must return the Mechanism to its park position.

If you need to stop the Kick Start unit, return the mechanism to the park (neutral)l position before the 10 seconds has expired.

Once the Soft starter has energized the Green run light will illuminate and when the Hippo is up to speed and ready for use, the Amber Light will be on.

To stop the operation in any of the above sequence, turn the On/Off switch to the Off (Stop) position.

HIPPO MILLS CROWNS A WINNER

90 years after Arthur Collins showed his first Hippo Mill at the Royal Show at Pietermartizburg, Hippo Mills, keeping up the tradition as an annual exhibitor at the show, highlighted the humble origins of Hippo Mills during a dinner where the grand- and great-great grandchildren of Arthur remembered their far-sighted grandfather.

In 1892 Arthur Collins, a young English inventor-engineer set foot in South Africa and after having developed many products still in use in the mining industry, and with the later the collaboration of his son Frank, in 1928 exhibited the first South African made hammer mill at the Royal Show in Pietermartizburg.

Needing a brand, the inventors turned to the news story of the year, being the travels of Hubert (later established to have been Huberta) the hippo along the east African coast from St Lucia in Zululand to deep into the Eastern Cape. Her death at the hands of farmers had the country in mourning. So the mill was called Hippo in commemoration of this spirited animal.

Today ABC Hansen is still manufacturing Hippo hammer mills, as well as a range of other agricultural equipment, along the same technology this gifted engineer envisaged. Cast iron, bolt together construction allowing any part to be replaced when worn and allowing movement between parts to avoid stress cracking in the structure due to vibration.

Moving with new market demands, today’s Hippo mill has overcome the dust problems inherent with hammer mills, a mechanical in-feed mechanism allowing for optimal performance, more efficient cyclones, easy dismountable delivery tubes, enhanced fan performance etc. However in essence, a Hippo mill remains a Hippo mill and is still considered a mill for a lifetime.

Today the range of mills from 4kW to 90kW has not only traditional farm & village applications but industrial applications for large industry and feed mills are more prevalent than ever. And Hippo mills are not only sold throughout Africa but also the USA, Germany, Denmark, Australia, Nieu Zeeland, Papua New Guinee, the Carribbean Islands and many other destinations.

At a function at the Royal Show on May 26 – 90 years after its first appearance there – the 3 granddaughters, one great and another great-great granddaughter of Arthur Collins presented on behalf of ABC Hansen, a free Hippo mill to Mr. Christopher Chilenje  of Malawi – a Hippo owner donating this mill to a community near Mzimba some 400km north of the capital Lilongwe, who showed greatest need of a village mill from all the contestants who entered into the Hippo competition. ABC Hansen shall be there when this mill is presented to the community, allowing processing of more than 200kg per hour of maize meal.

Hippo Mills will be there to present this award to the community and will keep you posted here about this event.

 

NAMPO SHOW

The biggest agricultural exhibition in Africa and beyond was another great event for ABC Hansen.

A total of more than 1,500 persons visited the ABC Hansen Grain, Scanwood and My Silo stands over the 4 days of the show, with over 400 official enquiries taken.

 

HUBERTA THE WANDERING HIPPO SURE GETS AROUND…

Huberta the wandering Hippo has been at it again. This year only she visited the USA, Germany, Holland, Australia, Nieu Zeeland, Papua New Guinee and the Carribbean apart from local African travels to destinations such as beautiful Kenya, the Pearl of Africa – Uganda, the Warm Heart of Africa – Malawi, the giant of Africa – DRC, mineral rich Angola, the green island of Mauritius and the eighth continent – Madagscar, apart from our Southern African countries.

Hippo and Universal mill exports to Pleasant Hills Grain of Nebraska is picking up speed with another container of 28 Hippo Baby as well as Hippo 47’s, 57’s and 69’s on its way.

Go to the ABC Hansen shop and get your discounted copy of “Huberta’s Journey” – a wonderful book for old and young, showing the joyful and finally disastrous interaction between humans and our wild animal brethren.

 

A Hippo Saved my Life

Struggling and suffering in Zimbabwe with food shortages and a family to provide for, I was at the end of my rope when my husband, who works in South Africa, brought back a Hippo hammer mill with diesel engine over Easter weekend…..

Hippos kill many people in Africa but this Hippo saved my life and will continue to provide for my family long after I am gone. And we even make some money by milling maize for the neighbours.

In this uncertain world, I can always be sure of my Hippo hammer mill.

Advantages of organic mulches in the orchard

uruguay-1888216_640

E. Joubert (Subtrop)

Manure, compost, woodchips, slashed material and pruned branches are commonly used as organic mulches in the orchard1. There are many agricultural advantages to correctly applied organic mulches in the soil2,3. These advantages include the presence of natural micro-organisms that enhances plant growth, plant health and product quality1,4,5. Micro-organisms generally include bacteria, fungi, viruses and algae6.

Actinomycetes are a remarkable group of bacteria that provide us with antibiotics we use in medicine today (Streptomyces). Some bacteria work symbiotically with non-legumes as nitrogen fixing bacteria (Frankia) and others such as Clostridium, Azotobacter or Bacillus are free-living nitrogen fixers. Nitrification is the aerobic process in which bacteria (Nitrosomonas & Nitrobacter) transform Nitrogen in the form of applied ammonia to nitrite followed by the oxidation of the nitrite to nitrate which is available for plant uptake. Nitrogen fixing bacteria also bind the nitrogen that is available in the atmosphere into a form that the plant can use. The oxidation process of sulphur that is important for crop production are also driven by bacteria6,7.

Bacteria act as decomposers of plant material (cellulose and lignin) and insect exoskeletons. The ‘eathy’ smell of turned healthy fresh soil is a sign of decomposing bacteria at work. Decomposing bacteria feed on organic mulches and make nutrients available for uptake into the plant. Table 1 lists the factors and practices that may add to the organic mulch content in soil or lead to organic mulch degradation.

Table 1 Factors and practices that influence organic matter contents in the soil8.

Positive factors and practices Negative factors and practices
Conservation farming practices Conventional farming practices
Pruned material remain in the orchard Remove pruned branches from orchard
Cover crops Erosion of top soil
Low soil temperatures and shade High soil temperatures and exposure to direct sun
High soil moisture content Dry soil
Surface cover Burnt vegetation
Compost and manure application Inorganic fertilizers
Adequate nitrogen Too much nitrogen
High plant productivity Low plant productivity
High root : above ground plant material ratio Low root : above ground plant material ratio

 

The addition of manure and compost to soil will raise the soil carbon content and result in unlocking valuable plant nutrients through decomposition. Mulches should ideally have a carbon: nitrogen ration between 25 – 100: 1. BEWARE the problems that can develop due to the injudicious application of compost and manure containing high phosphate (P) levels. Some guidelines when selecting compost and manure include the following:

  • Analyse the compost and manures to determine the nutrient levels.
  • Do not exceed the recommended nutrient application rates.
  • Determine if the fruit buyer or market will allow manure applications.
  • Avoid manure applications where soil P levels are high (> 75ppm, Bray 1 method).
  • Prevent manure and compost losses to surface and ground water.
  • Use composted manure that will contribute to the organic matter content of the soil.

 

One of the most important roles bacteria play in our soils are decomposition3,7. Carbon is an important food source for micro-organisms. In the soil, the organic matter content is 1.72 times the organic carbon content9. Carbon dioxide readily available in the atmosphere and biosphere are the biggest source of carbon in the soil. Other important sources of carbon can be grouped into live material, dead material and composed material9. Live material such as earthworms, plant roots and micro-organisms forms between 2 – 15% of the organic carbon source in the soil. A few recent articles listed the benefits of cover crops as live mulches. Some of the benefits include improved soil fertility, improved soil structure, better water management, reduced soil erosion, trap-crops for controlling pests and diseases and reduced weed pressure10 which in turn reduce the use of herbicides11 and promote of earthworms in the soil12.

Bacteria also plays an important role in the break-down of herbicides in the soil so that the concentrations does not reach poisonous soil levels. Bacteria populations excrete substances that aggregate small quantities of soil. This improves the soil structure which in turn increases the infiltration rate of water into the soil and aeration in the soil. Soil aeration forms a critical part of root and plant health.

Fungi that live in a mutualistic relationship with plants (e.g. Mycorrhiza and Trichoderma) are naturally occurring micro-organisms that can suppress plant pathogens such as Phytophthora and Botritis. These mutualistic fungi live inside roots or form a sheath on the root surface. They compete for space and nutrients with pathogens in and around the plant roots. Mycorrhizas also extend into areas which are often not within reach of plant roots, and thereby increase the total surface area that roots utilise as nutrient resources and water uptake. In turn, the plant provides the fungus with carbohydrates. Phytophthora species are oomycetes, and not fungi. Beneficial micro-organisms can also produce enzymes (cellulases and glucanases) that digest celluloses and glucan molecules in Phytophthora cell walls2. Indeed, mulching is used to control Phytophthora cinnamomi root rot in avocado and is beneficial for the development and reproduction of microbial organisms that are antagonistic to Phytophthora cinnamomi13.

The application of organic mulches has also been proven to increase earthworm populations14. The role of earthworms in the soil are:

  • Earthworms consume and digest organic litter, and excrete it in the form of nutrient-rich humus.
  • Take soil particles and organic material deeper into the soil where decomposed nutrients are made available to the deeper roots of plants.
  • Improve soil structure, aeration and drainage, which in turn can reduce soil compaction and crusting.

 

Another advantage of mulching is a reduced tree stress. A mulch layer serve as a temperature buffer since it reduces soil exposure to direct sunlight and consequently overheating of plant roots. In winter, mulches can result in warmer soil temperatures that allows for longer daily growth periods and earlier spring flushes2. Mulches significantly reduce evaporative water loss from the soil surface, improves soil permeability, biodiversity and significantly reduce soil compaction1,9,13. It is important to note that irrigation practices should be amended where mulches are applied in order to prevent waterlogged conditions that will promote anaerobic bacterial growth which has negative effects on plant health and pathogen related problems such as Phytophthora infection and root death due to hypoxic (no oxygen) conditions2. In a recent presentation at the South African Avocado Growers Organizations’ Research Symposium, Schoeman & Nortjé provided proof for the alleviating effect of 2L/m2 compost (costing R 3 600/ha) or 2g/m2 polyacrylamide (costing R 312/ha) on soil crusting. Soil crusting results in oxygen negative conditions15 and Phytophthora infection is a result of soil compaction16, while aeration increases nutrient availability and uptake and reduced nitrogen losses17.

Sustainable farming orientated table grape growers in the Western Cape saved 15 – 20% water and their nitrogen application costs reduced with 40% due to the increased soil carbon levels following mulches. In addition, their herbicide usage reduced with 65% even though the labour costs increased12. In summary, organic mulches plays an important role in biological, physical and chemical soil characterization. Mulches promotes an environment that beneficially affects plant health and product quality. Cultivated crops that originate form areas where the decomposed organic mulch layers occur naturally beneath the plants, will benefit from well aerated soils that contain high levels of organic mulch.

1. New Plantings
1.1 Soil preparation 1.1.1 Do a deep cross-rip of the new orchard.
1.1.2 Do soil pH (KCl: 5.0 – 5.5 or H2O: 5.8 – 6.2) correction according to soil analyses.
1.1.3 Adjust kation balances at least 3-6 months prior to planting. Ca(60-75%): Mg(15-20%): K(5-12%)
1.1.4 Do a phosphate correction to a depth of at least 60 cm.
1.1.5 Constructing ridges of 40 to 70 cm high x 2.5 m wide at the top on a 8 m row spacing.
1.1.6 Plant legumes (nitrogen fixing plants) or certain mustards as biofumigants.
1.1.7 Aim to improve the soil organic matter content by planting green manure and working it into the soil at least 3 months prior to planting or by the addition of compost, manure or continued application of liquid carbon. Mix compost / kraal manure into the soil to maintain good soil health through the continuous introduction of organic matter in the vorm of organic acids / manure or chips. Ground covers will help to stabilize the soil. Try to establish cover crops between the rows and do not apply raw manure to young trees.
1.1.8 Plan rows to allow for drainage, respect and use natural water sources, and if necessary, apply underground drainage, make watertrenches to avoid any surface water accumulation.
1.2 Planting of trees 1.2.1 Plant holes should be squired off by a spade. Ensure trees are not planted too deep / shallow.
1.2.2 Mix composted organic matter with the planthole soil before closing the hole again.
1.2.3 Paint the stems of the trees before planting with a potassium-, aluminium- or ammoniumphosphonate (or foliar application) and then paint the tree stems with a diluted white PVA paintmixture.
1.2.4 Always follows the products applied recommendations and only use registered products
1.2.5 Plant according to avocado planting recommendations supplied by the nursery.
1.2.6 Only plant certified trees with root rot resistant rootstocks such as Dusa or Bounty as clonal rootstocks and Velcick as a seedling rootstock.
1.2.7 Apply an organic mulch at least 1m around the tree without closing up the tree stem. The organic mulch may also form part of the retaining wall to consentrate the irrigated water around the tree which keeps the soil cool, reduce weed growth, prevent crusting and improve the soil.
1.2.8 First irrigation water should consist of a mixture of cytokinins and bascillus simbiotics to stimulate root growth and improve root and soil health. Repeat the  treatment every three months for the first year of planting.
1.3 After planting care 1.3.1 Irrigation water should be concentrated in the basin of the trees for at least the first 6 months to ensure the planting medium is wetted as well during irrigation without over irrigating the surrounding soil. If a irrometer is used to schedule  the irrigation there should be one placed into the surrounding soil and into the potting mix for the first six months or until the roots has grown into the surrounding soil. Make sure not to manage young trees too wet or not too dry.
1.3.2 Apply potassium- or ammonium phosphanate in the soil (as per label as soil drench, leaf or stem paint treatment) in the first two weeks after planting. Repeat every three months or replace it with a suitable biological product.
1.3.3 The trees should be sprayed monthly with products that contain both all relevant plant nutrients as well as plant stimulants such as cytokinins and auxins.
1.3.4 Spray or paint the stems monthly with Fosetyl-Al at 3.75g/? water for at least the first six(6) months.
1.3.5 Protect the tree against adverse enviromental conditions (sunburn and frost damage) by sparaying it regularly with a coaline product and or anti-stres products.
1.3.6 Fertilise the tree on a regular basis with fertiliser that contains N.P.K +Mg and with micro-nutriënt products such as zink and boron. There are products such as Ghwamis / controled release from Haifa that contains all this nutrients and is applied only ones a season for the first three years. Alternative: SAAGA mix – dry mixture of 3 parts KAN, 2 parts MAP and 1 part KNO3. Apply 20g SAAGA mix per tree for the first 18 months.
1.4 Pest & disease control 1.4.1 Enclose the trees individuely or the total planted area to protect the trees against antilope and other vertibra annimals.
1.4.2 Monitor regularly for the  locasts, beetles, termites and thrips that might damage the trees. Use a suitable registered product when neccassary.
2. Replant of Avocado’s: Adhere to all above mentioned points and give special attention to the following points.
2.1 Apply kraal- or chicken manure at least two months before planting on the plant rows and work it in.
2.2 Apply mulch under the trees after planting with a good quality mulch at least 1meter diameter around the tree.
2.3 Use a microbial soil conditioner to stimulate the soil microbes and to protect the trees against phytophthora infestations.
2.4 NB! The trees must be established on ridges to ensure good drainage and aeration of the soil. It is essential for root growth and health.
2.5 Intensive care must be taken to ensure good root growth and soil health for the first year after planting.
3. Non Bearing trees
3.1 General 3.1.1 Treat the soil against P.c. spores with metalaxyl at the beginning of the season and repeat the treatment six months later or use a biological soil conditioner six weeks after the metalaxyl treatment and repeat after three months.
3.1.2 Paint or spray the tree stems with a potassium-or ammonium phophate product every three months.
3.2. Trees with P. c. 3.2.1 Apply metalaxyl at the start of the season to the soil (according to tree age). After every metalaxyl treatment a biological soil conditioner should follow.
3.2.2 Paint or spray the tree stems with a registered potassium- or ammonium phosphanate product every two weeks
3.2.3 If the stems are thicker than 30mm it can then be injected with a single 20ml dosage of a suitable potassium- or ammonium phosphanate product, every 6 months. Injections should only be done as a last resort.
4. Bearing Trees
4.1. P.c. Already present 4.1.1 Inject the trees twice a season with a registered potassium- or ammonium phophanate prduct. Take care to ensure the prescribe MRL levels would not be exceeded at time of harvest.
4.1.2 First injection of the season should occur directly after fruit set.
4.1.3 Second injection four months later. The second injection should not be closer than 100 days before harvest.
4.1.4 Pick all the set fruit from infected trees to reduce the stress on the tree and treat it. Heavy invested trees should not be allowed to have fruit on because it slow down the recovery proses.
4.2. Maintenance 4.2.1 Only one series of injection per season after fruit set, usually in spring
4.2.2 Follow up with two leave sprays with a registered potassium- or ammonium phosphante product with a 90 day interval between sprays. Three months after the injection. Leaves flush must be semi matured. No more reddish leaves. Use with a penetrater product for best results.
5. General practises to maintain good root health
5.1 Soil should always be well aerated and drained with no compacted layers up to  a depth of 1000mm.
5.2 Always plant on ridges if possible to ensure good drainage and soil erasion.
5.3 Irrigation scheduling should always aim to induce oxygen into the soil profile as well, not just for applying water.
5.4 Increase the organic compound of the soil for improved aeration and microbial activity. Apply organic mulch around trees where there is no natural organic layer present for instance young newly planted trees or trees that lost its normal leave mulch deu to P.c infestation.
5.5 Keep Calcium(Ca) levels optimum. Base saturation should be between 65% to 75% depending of the soil texture.
5.6 Boron is also essential for root health and growth. Apply regularly small amounts through the irrigation or twice a season every six months with a slow release boron product.
6. Water & irrigation systems
6.1 Do a water test to determine the mineral as well as the pathogenic content. Attached is the water standards regulations.
6.2 Ensure the irrigation system is suitable for avocado irrigation and fertigation so that fertigation can be done through the system.
6.3 Use soft acid products to clean the system from salt and mineral layers and particles on a regular base.
6.4 Hydrogen peroxide shoiuld be used on a continious base to ensure the water and irrigation pipes stay clear of organic films and can be pathogen free.
6.5 Use irrometers to do irrigation scheduling.  Also use a soil auger to monitor the irrometers and irrigation shedule.

Delivery of Grizzly Chippers to Pecan Country

It was the middle of July, on a cold winter’s morning.  Scanwood Solutions delivered two Grizzly chippers to Nutmech in the heart Pecan Country in the heart of the Vaalharts Irrigation Scheme.

Nutmech had arranged the sale, subsequent delivery and demonstration of two models of Chippers, the Grizzly 180 (http://www.scanwood.co.za/products/Grizzly-Wood-Chippers/Grizzly_Chipper_BX72R_180-woodchipper.php) and the Grizzly 250 (http://www.scanwood.co.za/products/Grizzly-Wood-Chippers/Grizzly_Chipper_BX102R_254-woodchipper.php). The chippers were demonstrated using Kubota orchard tractors. The wood supplied was freshly hedged Pecan Nut. James Pitout of Scanwood Solutions was on hand to provide product knowledge and training on the two models on display.

The farmers were impressed with the chipping ability of the chippers. One asked me if it could keep up with his staff feeding wood into the chipper. I replied by saying his staff wouldn’t be possible for his staff to overfeed it.

Farmers’ comments about the chipper included many remarks on the rugged build of the chippers; the ease of maintenance as well as the affordability thereof. They also appreciated the availability of spares in South Africa and the three-year warranty.

The success of the day was revealed in the sale of two further chippers during the demonstrations.
