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.

Qualified materials are fed steadily into the grinding chamber by a variable-frequency belt feeder. Inside the chamber, materials are ground by the mill.
The ground powder is carried by airflow to the classifier. Unqualified coarse particles drop back for regrinding, while qualified fine powder flows into the cyclone collector for separation and collection, then discharged as finished products.
Air circulates back to the fan via the return pipe to form a closed loop. The whole system runs under negative pressure and is fitted with a pulse dust collector, fully meeting environmental emission standards.
A: PMD is the first roller mill equipped with permanent magnet direct drive motor. It cancels complicated gear transmission, cuts total power consumption by 15%, and delivers more stable power output and higher transmission reliability.
A: Yes. It is built with IoT intelligent system, supporting mobile APP real-time data collection, multi-point running condition monitoring and automatic fault early warning, no need for full-time on-site operators.
A: Max feeding size is 35–50 mm; adjustable finished powder ranges from 0.038 mm to 1.6 mm, meeting medium-fine powder demands for limestone and petroleum coke.
A: It is ideal for medium-hard non-metallic ores, especially petroleum coke, limestone, calcined coke. We have delivered stable 80,000 TPY petroleum coke grinding lines and large limestone projects.
A: The whole line runs under fully sealed negative pressure, matched with pulse dust collector. Closed air circulation eliminates dust overflow and meets global industrial environmental standards.
