Introduction
The classifier system consists of air classifiers, cyclone separators, dust collectors, induced draft fans, and electric control cabinets.The material flows with the air from the lower part of the classifier into the classifying chamber at a high speed, and the coarse and fine particles are separated by the centrifugal force generated by the high-speed rotating classifier and the centripetal force generated by the air flow.The fine particles that meet the particle size requirements are collected in the cyclone separator and the dust collector through the blade clearance of the grading wheel.The fine particles entrained by the coarse particles are thrown by the grading wheel and fall to the lower part of the classifier.The natural gas is rectified into a uniform swirling flow through the diversion chamber to further separate the fine particles mixed or adhered to the coarse particles.The separated coarse particles are discharged from the coarse material outlet at the bottom of the classifier through a rotary valve.The speed of the grading wheel is controlled by the frequency converter.
Outstanding advantages
1. The particle size of the graded product can reach a fineness of up to D97: 3 microns, and the product particle size can be adjusted.
2.High fineness, large output
3.With a small gap, the gas seal prevents large particles from entering
4.Divided into horizontal single rotor and horizontal multiple rotor two, the user can choose according to actual needs.
5. The multi-rotor classifier not only achieves high output, but also maintains excellent performance at the cutting point accuracy.
6 .The grade wheel can be made of carbon steel, stainless steel, ceramics, polyurethane and other materials according to customer needs
7.The system operates under negative pressure. The dust emission meets the national environmental protection standards.

Introduction of working principle
Classifier and cyclone separator, dust collector, induced draft fan constitute a grading system. The material under the action of the fan's pumping force moves from the lower inlet of the grader to the classification zone with the ascending airflow. Under the powerful centrifugal force generated by the high-speed rotating classification turbine, the coarse and fine materials are separated, and the fine particles meeting the particle size requirements are classified. The wheel blade clearance enters into the cyclone separator or the dust collecting device. The coarse particles entrain some fine particles and the velocity disappears. After falling along the wall of the cylinder to the secondary air outlet, the thick and fine particles are separated by the strong panning action of the secondary air. The particles rise to the secondary grading stage and the coarse particles fall to the discharge port.
