PPM Disc Grader

PPM disc graders are engineered to efficiently separate and sort irregular or unwanted sized pieces of product from ideal sized pieces. Disc rollers convey chips, cereal or other products across one sizing section to another.

Disc roller speeds progressively increase along the length of the machine to ensure product is spread into a single layer, allowing for each piece of product to be sized accurately – undersized product slips between discs, larger products are conveyed by the rotating discs and moved forward.

Each unit is highly customizable and can be designed to suit a variety of applications and grading parameters based on your unique product specifications. PPM Disc graders sort with extreme accuracy and ensure gentle handling for even the most fragile products.
