The GF Series grinders from Process Control Corporation are used as part of an asr® Automatic Scrap Recycling system for in-line recycling of production film scrap. GF Series grinders are designed to provide efficient, uniform grinding of film scrap. There are four cutting chamber sizes available along with different horsepower motors to accurately match the grinder to the required scrap rate. The GF Series grinders are available in configurations that accept edge and bleed trims, roll scrap, and loose scrap.
Standard carbide-coated knives are employed in the system, increasing the time between sharpening. The rotor knives approach the stationary bed knife, or knives, at a steep angle to ensure a clean scissors-cut. ...
There are (2) different version of the GFA Series grinder.
The GFA with Air Bypass is designed to handle edge and/or bleed trims only. This design utilizes a 5 HP fluff conveying fan for both inducing the trims into the grinder cutting chamber and for blowing the ground fluff out of the grinder. There is no need for a separate trim removal inducer or air eliminator.
The second version is for handling both trims and off-spec roll scrap. This design does require a separate inducer, eliminator and roll feeder and utilizes a 2 HP fluff conveying fan to blow the ground scrap. Both versions are designed with a single stationary knife and (2) rotating knives.
The standard knives are carbide coated to promote long life.
