Hippo No. 57 Hammermill with Air Conveyor

Hippo hammermills rapidly pulverize a wide range of materials from grain, beans, herbs and fibrous roots to minerals, plastics, glass, bone and recyclables. Materials enter the milling chamber and are impacted by hammers rotating at high speed. Size reduction occurs until particles can exit through the holes of a perforated screen covering the discharge. Interchangeable screens offer hole sizes ranging from 0.6mm to 25mm.

As a result of hammer milling, in addition to particle size reduction some materials (glass bottles and lobster shells, for example) experience a high degree of bulk reduction, creating storage and transport efficiencies.

Milling chambers are constructed of high strength cast iron plates with bolted construction that eliminates common stress points to prevent cracking. After extended use, this method of construction allows fast, easy, on-site replacement of worn parts. Built for the demands of commercial and industrial grinding, Hippo hammermills are fast, efficient and durable, and their low cost won't break your material processing budget.

In use across the U.S. and around the world, South-African made Hippo mills are available with horsepower ratings of 5 to 100 hp. The Hippo #57 commercial hammermill with a VFD is equipped with a 40 hp, 208/230/460VAC, 60hz, 3-phase inverter duty rated motor. The VFD is not pre-wired to the motor and can be programmed to reduce the rotor shaft rpm. Slowing the speed of the rotor shaft can increase the likelihood of getting a coarser grind in hemp and other products, while still utilizing the material handling fan to move product from the mill to the material collecting cyclone.

Hippo hammermills feature rigid hammers with replaceable tips of long wearing, impact and abrasion-resistant Bennox steel. The screen is located in the bottom half of the hammermill chamber, covering an arc of about 180°. Milled material is transported from the discharge of the mill by an impeller fan mounted on the drive shaft, and delivered to the cyclone and dust separator. Suction created by the material handling fan aids transport of the product through screen holes.

Stock interchangeable screens for the Hippo #57 hammermill are available with hole sizes of 0.6, 0.8, 1.0, 1.2, 1.6, 2, 3, 5, 6, 10, 15, 20 and 25mm. The top half of the milling chamber swings open for full access to the hammers and screen, and screens can be changed out in just 30 seconds without tools.

Hippo mills are manufactured to high precision standards, with non-cast components cut by laser or plasma for excellent fit. High quality bearings are used, and lubricated with quality synthetic lubricant.

A high strength magnet is fitted to the feeding hopper, isolating harmful ferrous metal items before entering the mill and damaging the screen.

All Hippo mills are tested before shipping and are covered by a 1 year warranty against defects in materials and workmanship.
