After the crushing of the vast majority of the ore has not been able to become the furnace charge, after crushing of ore also need after dressing treatment before it can become the furnace charge. As the grinding head of the grinding operation, which is energy, steel and other raw materials consumption of the largest. Therefore, saving energy and reducing consumption, a crushing and grinding equipment research need to reach the ultimate goal, more crushing and less grinding is energy-saving and consumption of grinding equipment an important indicator, the key problem is reducing the crushed product on the final grain size. As grinding equipment of a crusher, cone crusher not only production efficiency is high, and the material particle size is small and uniform, can achieve the rocks and minerals from 350mm broken below 10 mm different levels of particles, so as to meet needs of the mill feed size. So cone crusher has become the main crushi
