S. Howes

Knife Cutter


The S. Howes industrial knife cutter provides fast, uniform cutting of a variety of product with a series of rotary and fixed bed knives. A sizing screen prevents oversized product from leaving the cutting area until the desired size has been obtained.

Rotors spin at a nominal speed of 500 rpm to cut various complex materials, producing a tip speed of approximately 280 fpm. The throughput of the machine is related to the screen size installed. If a high throughput process is required while attaining significant size reduction, two or more machines can be combined in series to provide staged size reduction without significantly reducing throughput.

Several models can accommodate material capacities from 2,400 to 7,000 lbs per hour and can be custom-engineered for the most demanding cutting requirements.
