Wolong YFBKK series is the prime mover for mechanical equipment that breaks coal blocks and grinds them into coal powder. It is widely used in cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metal beneficiation, glass and ceramics and other production industries to dry or wet grind various ores and other grindable materials; it can also be used in medicine, textiles (such as cotton fiber, flax fiber, chemical fiber, etc.), metallurgy (magnesium powder, aluminum powder, carbon powder, etc.), food processing (such as wheat, corn, cereals, etc.), feed processing (blood meal, fish meal), fertilizers, tobacco, papermaking, synthetic materials (such as plastics, dyes) and other places where combustible dust exists in China three phase induction motor manufacturers.

The motor can be customized according to customer requirements to Nanyang brand, Wolong brand, Schorch brand, etc.

Model Reference

YFBKK-500-6

YFBKK- Series code, Y indicates three-phase asynchronous motor, FB indicates dust explosion-proof type, KK indicates air-to-air cooler, IC611 structure.

500-6- Specification code, indicating shaft center height 500mm, 6 poles.

(ps: If it is a coal mill load, high starting torque requirements are for dust explosion-proof coal mill special motors; if normal starting torque requirements are for dust explosion-proof motors.)
