Detail

Leveraging Wolong Nanyang Explosion’s extensive experience in high-voltage box-type asynchronous and coal mill motors, YFBKK series incorporates the latest advancements in technology, materials, and manufacturing processes. Its compact design, high starting performance, low noise and vibration, and robust protection features ensure safe and reliable operation.
The YFBKK series high-voltage box-type three-phase asynchronous motor for coal mill is the prime mover for mechanical equipment that breaks coal blocks and grinds them into coal powder. The product is used extensively in a number of industrial sectors, including cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metal beneficiation, glass and ceramics. It is also employed in the processing of various ores and other grind-able materials, as well as in the medical and textile industries. It is also suitable for use in a wide range of other industries, including metallurgy (for grinding magnesium powder, aluminium powder, carbon powder and so on), food processing (for grinding wheat, corn, cereals and so on), feed processing (for grinding blood meal and fish meal), fertilisers, tobacco, papermaking and the production of synthetic materials (such as plastics and dyes).
