Power Grater
Multifunctional material size reduction machine.
Our Power Grater size reducer features a unique multifunctional design that provides grating, delumping, particle sizing, crushing, shredding, and de-agglomeration of various products. With its low horsepower requirements, low paddle speed, and heavy-duty construction, the S. Howes power grater is an economical choice for reliable size reduction with less fines.
Power Graters can be designed in stainless steel, carbon steel, or other alloys, and screens can be customized to your requirements. The screen cage can be removed with minimal tools for fast screen change and cleaning in sanitary applications. Optional, hinged cleanout doors and view windows allow access to the rotor assembly and all interior casing areas.
The S. Howes’ Power Grater consists of a dust-tight housing that contains a paddle assembly and an aperture screen. The screen features holes edged by raised cutting edges that grate or shred the product as it is pushed over the screen. The paddles rotate, and the product is rubbed against the grater screen for clean, efficient reduction.
