Hippo hammer mill grinder machines 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.

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 mills are fast, efficient and durable, and their low cost won't break your material processing budget.

The Hippo #69 hammer mill is IN STOCK and available with or without a 60HP electric motor and starter or VFD. The motor is a 208/230/460VAC, 60hz, 3-phase inverter duty rated motor. The starter is a "well panel" enclosed starter for 460VAC. The VFD is available for 230VAC or 460VAC. The starter or VFD is not pre-wired to the motor. The VFD 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 hammer mill grinders feature rigid hammers with reversible, replaceable tips of long wearing, impact and abrasion-resistant Bennox steel. The screen is located in the bottom half of the grinding 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 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.

*Output rate is based on dry corn for reference, and will vary substantially for other materials based on factors including density and frangibility. **Rotor RPM is infinitely variable with optional VFD (variable frequency drive) for fine-tuning of speed and particle size. ***Most product will exit even finer than the size of the holes in the screen.
