The machine is mainly used with rubber grinder XJM600, and also can be used alone. Rubber powder processed by grinder is divided into two groups, dividing range can be freely adjusted between 60-150 meshes with the efficiency of over 75%.Work principle: When gum powder enters the machine from the in-filler above it, the powder will drop into the selector after division; By the action of the rotor cross-airflow, the rubber grains will be dispersed adequately then the thick grains and the fine rubber powder are ejected out through different outlets. The machine has tight construction for convenient installation and maintenance, fitting for powder dividing with water content below 1% and final product with powder rate between 60-150 meshes.
