    It is suitable for dry grinding, constant temperature or low temperature non medium grinding of all kinds of materials with Mohs hardness below 9. It can be used in series with multi-stage classifier to produce products with multiple particle sizes at one time.

    High precision grading rotor

    The world’s leading high-precision grading rotor, linear speed up to 80m / s, to ensure that the vertex cutting accuracy, can meet the demanding product requirements.

    Automation control system

    The control system adopts program control, which is easy to operate; the motor can be connected by belt, which can improve the speed and break through the problem of no high-speed motor.

    Large scale and large capacity

    The grading wheel can automatically separate materials through air flow, without coarse particles; the precise weighing control system can be selected, with high product stability and good consistency.

    Working Principle and Equipment type features

    Jet Mill, cyclone, bag filter and fan constitute a complete milling system. After the compressed air is filtered and dried, it is sprayed into the milling cavity at high speed through Laval nozzles. At the intersection of multiple high-pressure airflows, the materials are repeatedly collided, rubbed, and sheared to be milled. The milled materials rise with the suction of the fan. The air flow moves to the classification area, the coarse and fine powder are separated under strong centrifugal force generated by the high-speed rotating classification turbine. The fine particles that meet the particle size requirements are through classifier wheel and collected by cyclone and bag filter; the coarse powder drop to the milling area and continue to be milled.
