Frequency conversion speed regulation, stable and reliable
The Classifier rotor is installed vertically, can be adjusted by frequency conversion, the particle size distribution can be flexibly adjusted; large capacity, high efficiency, low investment are realized.
Meet the requirements of high-purity materials ultrafine milling
The key components such as inner lining, classifying wheel and nozzle can be made of ceramic materials such as alumina, zirconia, silicon carbide, etc., to ensure none contact with metal during the entire milling process and meet the requirements of high-purity materials.
High precision assembly
The world’s leading high-precision classifying rotor ensures accurate cutting of the apex, which can meet the demanding product requirements. The use of special shaft sleeves is worry-free, labor-saving and reliable.
Secondary air inlet design
High energy utilization rate, facilitates the flow of materials and improves efficiency of powder selection.
Working Principle and Equipment type features
Jet Mill, cyclone, bag filter and fan constitute a complete milling system. After the compressed air is filtered and dried, it is sprayed into the milling cavity at high speed through Laval nozzles. At the intersection of multiple high-pressure airflows, the materials are repeatedly collided, rubbed, and sheared to be milled. The milled materials rise with the suction of the fan. The air flow moves to the classification area, the coarse and fine powder are separated under strong centrifugal force generated by the high-speed rotating classification turbine. The fine particles that meet the particle size requirements are through classifier wheel and collected by cyclone and bag filter; the coarse powder drop to the milling area and continue to be milled.
