The Energy-Saving ball mill is widely used in powder making production line in industries, like mining, building materials and chemistry industries. It is a key equipment to grind all kinds of ores and other materials. The cement ball mill is composed of feeding part, discharging part, turning part and driving part (reducer, small driving gear, electric motor and electric control). The quill shaft adopts cast steel part and the liner is detachable. The turning gearwheel adopts casting hobbing process and the drum is equipped with wear-resistant liner, which has good wear-resistance. The machine is with stable and reliable working condition. Moreover, according to different materials and discharging methods, there are dry cement mills and wet cement mills for choice. 　　　 

Henan Zhengzhou Mining Machinery Co., Ltd. specializes in the production of energy-saving ball mill; this series of ball mill is suitable for ore dressing, chemical, coal, and cement and tetractpry sectors to operate fine grinding. 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%, according to Babbitt burning, downtime, the phenomenon of stopping production, not enough to improve the ball concentricity, run instability, current fluctuated, wear serious phenomenon hollow shaft. While use of 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 saving at 20%-30% power.
