Abstract
A grinder with independent blades and an apparatus and methods to cause the product to be stretched, aligning the fibers of the product.
Claims4
A grinding machine comprising:
- a grinder portion;
- a feed screw or auger to advance material in the hopper through said head;
- independent speed control blades attached to a motor that is independent from said feed screw or said auger;
- said motor providing variable speed control;
- an orifice plate;
- said orifice plate having said independent speed control blades on outside of said orifice plate;
- a collection cone located downstream of said orifice plate;
- said orifice plate comprised of a plurality of grinding apertures and at least one collection passage;
- geometry of each of said grinding apertures create a venturi effect;
- said apertures have a diameter such that ratio of diameter of sphere in said orifice plate to diameter of cylinder of said orifice plate is approximately 1.1 to 2.5.
