Cumberland Granulator Rotor Knives and Stator Knives for the plastic and rubber industries

Cumberland granulators always meet the demanding needs of size reduction industries. Many plastics and rubber processing plants around the world use them daily, and so operators look for improvement of granulators usage.

How fast the blades become dull depends on a volume of processing materials, knife geometry, and also steel being used.
