Working Principle
After crushing, the qualified material is fed evenly and quantitatively into the main grinding chamber by a variable frequency belt feeder for grinding. The ground material is then sent by airflow from a blower to a classifier for grading. Under the action of the classifier, material that does not meet the fineness requirements falls back into the grinding chamber for regrinding, while the qualified material is carried by the airflow through a pipeline into a cyclone dust collector for separation and collection. The collected material is then discharged as the finished powder through a discharge device. The separated airflow returns to the blower through the return air duct at the top of the cyclone dust collector. The system operates under negative pressure and is equipped with a pulse dust collector, meeting national environmental protection standards.
The maker offers installation guidance, training, remote diagnosis and follow-ups, with key wear parts stocked for fast shipment. The smart system enables cloud diagnosis to locate most faults online. An annual agreement lets the maker track data and warn early.
The PMD New-Generation Permanent-Magnet Direct-Drive Intelligent European Grinding Mill applies thin-oil lubrication to the main unit and rollers in a closed loop with online monitoring of temperature, level and pressure, allowing refill without shutdown. With the reducer removed by direct drive, lube points drop and maintenance simplifies, while thin oil prevents downtime and extends bearing life.
The PMD New-Generation Permanent-Magnet Direct-Drive Intelligent European Grinding Mill drives the central shaft directly with a permanent-magnet synchronous motor, eliminating the reducer, fluid coupling and coupling. This direct layout transfers power with less loss; main-shaft speed is precisely controlled by frequency conversion for smooth, low-noise operation across conditions.
The PMD New-Generation Permanent-Magnet Direct-Drive Intelligent European Grinding Mill permanent-magnet motor has high protection and sealed structure; daily care is just keeping cooling ducts clean and monitoring winding temperature and current. With no brushes or reducer gears, mechanical wear is minimal—periodic checks plus smart monitoring ensure long maintenance-free runs.
The PMD New-Generation Permanent-Magnet Direct-Drive Intelligent European Grinding Mill uses a permanent-magnet synchronous motor driving the main shaft directly, removing the reducer and coupling for a shorter, more efficient chain. Versus asynchronous systems it saves about 15% energy, with low-speed high-torque starts, stronger overload capacity and fewer wear-prone transmission parts.
Qualified fine powder enters the cyclone collector for gas-solid separation and is discharged by a rotary valve; ultrafine fractions are captured again by the pulse collector. Product is pneumatically conveyed to silos or ton-bag packers for automated filling under negative pressure.
