The classifier disc cell mill is divided into three parts:the premix chamber,the grinding chamber,and the classifier.Material is drawn into the premix chamber by an induced draft fan for preliminary mixing,ensuring that the material enters the grinding chamber in a uniform fluidized state.The main component of the grinding chamber is a vertically installed multi-stage rotor,which consists of multiple discs sandwiched between two support disc plates mounted on the main shaft.
The interior wall of the grinding chamber is lined with vertical grooves that are 6 to 8 millimeters deep,and the gap between the rotor discs and the lining strips is 2 to 5 millimeters.When the rotor spins at high speed,it generates turbulent airlow in a"nested"pattern.The airlow pressure,friction,and shearing forces,along with a chamber wind speed of 30 meters per second and a rotor linear speed that can reach up to 120 meters per second,quickly reduce the material intoultra-fine powder.
After grinding,the material is carried by the airflow into the classifier section.The entire system's airflow and the classifier can be adjusted according to the particle size requirements.Larger particles are separated by the classifier wheel and,under the influence of gravity,fallback into the grinding chamber for further grinding until the desired particle size is achieved.

The pin disc mill with twin rotor is an integrated piece of equipment that combines both mechanical and air- swept grinding methods,featuring a horizontal design.Inside the chamber,there are two layers of disc rotors and toothed stators that work together.The unique disc rotors,when spinning at high speed,create an orderly air vortex with the toothed stators.This vortex causes the material within the grinding chamber to be sheared and impacted by the toothed nests and discs,quickly reducing the material into ultra-fine powder.The interaction between the disc rotors and the toothed stators ensures a thorough grinding process,which guarantees an even distribution of particle sizes in the finished powder.

Core-Pulling Type Self-Cleaning Magnetic Separator
The core-pulling type self-cleaning magnetic separator mainly consists of a reduction motor,a casing assembly, permanent magnetic bars,a three-way valve,and a pneumatic control system.It operates with a top feed and bottom discharge design.During operation,the permanent magnetic bars are inserted into the casing assembly,creating a strong magnetic field around the casing.The motor rotates,driving the entire setofmagnetic bars,allowing the casing to come into full contact with the material.Magnetic foreign objects are attracted and adhere to the casing. Demagnetized material,due to gravity or negative pressure,moves downward into the three-way valve's discharge outlet.
For demagnetization,the motor stops,and the three-way valve's valve plate is opened to the slag discharge end. A dual-cylinder mechanism actuates the permanent magnetic bars to separate from within the casing,causing the casing to lose its magnetic attraction and the magnetic foreign objects to falloff.Meanwhile,the motor rotates to shake offany residual magnetic foreign objects from the casing.This equipment is suitable for low-moisture,dry powders and granular materials.
