Hippo Hammer Mills
A household name where hammer mills are concerned.
Cast Iron
Constructed of easily replaceable special alloy cast iron wearing parts.
Supplied with two screens with sizing of your choice
Bolt Together
Parts bolt together to eliminate stress cracks over weld lines.
This is a serious problem in all other welded lesser hammer mills.
Bennox steel hammers
High wearing Bennox or Hardox steel hammers. This ensures low downtime and low maintenance cost. Rotors are pre-balanced for low vibration levels.
What Makes This Design Unique?
1. All parts are bolted together, this ensures that no vibrations are transferred into individual parts. For this reason stress cracks will not develop in the steel.
2. There are no chopping knives or flails. The material is fed directly onto the tips of the rotating hammers.
3. Special alloyed cast iron is not only able to handle abrasion better, if a part is worn – such as the milling back plate – it’s simply replaced.
But note, the Pygmy, L63 and Mammoth are not cast iron models. The Pygmy is a low cost, well made welded mill while the Mammoth and L63 has Bennox mill backplates but is otherwise fabricated of mild carbon steel, however, still bolted together.
Hippo Hammer Mills dates back to 1928 when the English engineer Arthur Collins introduced his first version of the Hippo Mill model 1 at the Royal Agricultural Show in Pietermartizburg, Natal, South Africa. A cast iron, bolt-together machine, still basically made in the same way, many thousands of mills, and many new models later, by its inheritor ABC Hansen today.
What can a Hippo hammer mill do?
- Wood – various applications such as feed for ruminants and game, very fine powder for Masonite board and particle board, chips ground down for briquettes, very fine wood for plastic/wood extrusions, fillers for glue, nut shells.
- Cellulose for fire lighters and explosives, specialty papers, insulation and recycling from various sources.
- Plastics – from recycling waste to conversion into fuel and pellets for remanufacture.
- Electronics waste, hard drives, laptops, glass, metal shavings, aluminium.
- Chemicals, pharmaceuticals, fertilisers, pigments and textile chemicals including salts, sodium nitrate and virtually all non-explosive products.
Items not able being milled with a Hippo is the exception rather than the rule.
a mill for a lifetime
All Hippo mills have fixed hammers from hard wearing bennox steel rather than fails, allowing for greater particle damage. Hammers are spaced to run over the entire width of the screen creating higher abrasion and impact damage to particles and allowing for faster screening. The fallacy that 360 degree screens allow for higher capacity is just that. The fixed milling backplate causes far more particle damage than a perforated screen.
A mill for a lifetime? We still repair and replace parts of mills originally manufactured during the 1940’s and 50’s. Can it anything else?
