The design of the HIPPO HAMMER MILL is unique in that there are no chopping knives, as the material is being fed directly onto the tips of the rotating hammers in the direction in which the hammers are rotating. The milled material is transported from the bottom of the mill housing by means of four-bladed cast iron material handling fan mounted on the same shaft as the rotor and delivered to the cyclone.
A wide range of screens is available, from 25mm down to 0.6mm aperture.

Three drive options are available on the Hippo #57
– Electric drive – 30KW 380V 50HZ 2 Pole
53HP Water cooled JD diesel engine
– Tractor PTO Drive

The Hippo #57 is fitted with an large integrated cast iron material handling fan – which pulls milled material from the milling chamber, and the product is then pushed to a cyclone, fitted with an 8 sock dust bank – for practically dust free milling.

Fitted on all Hippo #57’s as standard is our innovative automatic infeed control system, that regulates the feed into the mill automatically, using the airflow from the material handling fan, to open and close the inlet of the hammer mill, depending on the airflow through the milling chamber (a fuller chamber, allows less airflow, which will then have the inlet move to a closed position preventing overfeeding. Once the milling chamber is emptied and airflow isn’t restricted anymore, the air flow will pull open the inlet again – allowing product to be fed in again – thus ensuring optimal performance from your hammer mill.

HIPPO HAMMERMILLS have been manufactured in South Africa since 1928, and parts are readily available from our warehouse, usually within 24 hour from order.
HIPPO HAMMERMILLS from models Baby up to Size 69 are based on cast iron milling plates, which drastically increases the lifespan of the mill, compared to competitors. The Hippo 57 is the mid range model in the commercial range of mills, with high capacity, and high quality parts. All milling tips are manufactured from Bennox (or optionally Hardox for highly abrasive materials) to ensure long lifetime on these parts.
