As early as the mid-1980s, China's Hubei Dayukou phosphate mine had been introduction Rollercone rolling hydraulic cone crusher for the crushing operation with favorable results, convenient discharging adjustment and reliable overload protection. In recent years, Qinghai Saishitang copper mine selects U.S. Cedarapids group Automaxl000 type rolling bearing cone crusher, which adopts rolling bearings support and surrounding multi-cylinder hydraulic lock structure, with high production capacity, large crushing ratio and fine product size; it can break ore from 160 mm to 12 mm and 1 equipment can achieve two sections effect of other equipment’s.
MVP-type cone crusher structure is significantly different from traditional cone crusher. The biggest difference is: MVP-type use rolling bearings instead of the traditional sleeve and sphere tile. The clearance between rolling bearings is much smaller than that of sliding bearing, so crushing machine can run smoothly; and set point in the discharging is more precise, so that the crusher can precisely and stably work in the proven discharge opening and reduce the impact of crusher on the body and other parts, significantly improve the status of the force, improve the reliability and security of the machine. As we all know, eccentric bushing lubrication of traditional cone crusher is an important operational factors affecting the operation of the machine. Due to the restrictions of eccentric bushings motion, the gap value is usually quite large, sometimes reach as high as 6-10 mm, therefore, it is difficult to form a good film when machine working and only keep working in a dynamic film state a by pressure oil. Once the external factors cause poor oil flow, it will result in bearing lock or even broken shaft.
MVP-type cone crusher completely overcomes the above-mentioned shortages, and improves work efficiency of the machine.
