The process principle is different materials have different balanced speed, the same material with different shapes also have different balanced speed. The air grader system is to use this principle to design different air flow rates in each functional area. The materials with different balanced speed passed, according to its own balanced speed separated out qualified fibers in the top of the air grader, crude fiber in crude fiber area separated, metal particles, sand, stone, fibers and other heavy objects in the heavy objects area separated.

We developed the automatic control air grader system, based on artificial intelligence PID fuzzy controller, can maximize the recovery of qualified fiber, reduce power consumption, improve the stability and improve the quality of products!
