The emergence of PMD grinding mill marks a major breakthrough in grinding mill technology.This model is the first to apply a permanent magnet direct drive motor to a roller mill, completely overturning the traditional transmission mode and achieving a deep integration of power system and intelligent control. The permanent magnet direct drive technology provides stronger and more stable power output for the grinding machine, significantly improves the reliability of the transmission system, greatly reduces system power.


More stable power, achieving a comprehensive energy saving rate of 15%.

Intelligent lubrication system enables non-stop operation.

It provides warnings, ensuring stable operation and higher quality powder.

An intelligent control system, it collects and analyzes data in real time.

Materials qualified after crushing are uniformly, quantitatively and continuously conveyed to the grinding chamber of the main unit by a variable-frequency belt feeder for grinding. The ground materials are driven by the air flow of the fan and conveyed to the classifier for particle size classification. Driven by the classification system, materials that fail to meet the fineness requirements fall back into the grinding chamber for regrinding, while qualified powder is carried by the air flow through pipelines into the cyclone powder collector for gas-solid separation and collection, and finally discharged through the discharge mechanism as finished products.The separated air flow returns to the fan through the air return pipe at the top of the cyclone powder collector, forming a closed-loop air flow circuit. The entire system operates in a negative pressure mode and is equipped with a pulse dust collector, with all emission indicators complying with national environmental protection standards.
