Bearing-type drive ball mill is a technological changing type, compared with the traditional ball mill:15% lower operating current and reduce the starting current 50%. Improve the phenomenon of ball concentricity not enough, run instability, current fluctuated,  wear serious phenomenon hollow shaftaccording to the phenomenon of Babbitt burning, downtime, the phenomenon of stopping production. after adopt the rolling bearing, the hollow shaft can continue to use, save 90% lubrication oil, improve the loading of 20%, increase production by 15%, 10% speed increase, each power saving can arrave 20%-30%.  


the main products of company include: ball mill, rotary kiln, vertical preheater, cooler, crusher, metallurgical coke oven, magnetic separator, flotation machine, classifier, feeder, bucket elevator, preheater, dust collector, elevator, drier, and other equipments relate to metallurgy, cement, lime, mineral processing, refractory, chemical industry.
