Ball mill is the key equipment for secondary grinding after crushing. And it is suitable for grinding all kinds of ores and other materials, no matter wet grinding or dry grinding.Besides, it is mainly applied in many industries, such as ferrous&non-ferrous metal mine, building materials, chemical Ball mill is the key equipment for grinding after the crushing process, which is widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics and can be used for the dry and wet grinding for all kinds of ores and other grind-able materials. Coal mill is an important auxiliary equipment for coal-powder furnace, and it has three methods to crush the coal lump and grind them into powder,like crushing, impacting and grinding. Air swept coal mill is the main equipment in cement plant for both drying and grinding of the powders. After materials enter Ball Mill through feeding device, the surface of pulps in the cylinder body will be higher than that of the minimum bus of inner diameter of the discharging tube. At this time, materials ground by ball mill can be discharged out of ball mill through the discharge pipe. This type of ball mill will have the end of discharging pipe made as horn-shape at the end of outlet pipe inside hollow shaft. In addition, this kind of ball mill is equipped with a block ring at the end of the hallow shaft to prevent the pulp from leaking into the bearing.through the holes of bolts in the cover. At the same time, overflow type ball mill also has a spiral inside the discharging pipe. The direction of the spiral is opposite to the running direction of cylinder body, which can prevent steel balls and ores from being discharged out of ball mill. However, it has low capacity and is easy to over-crushing. The quill shaft adopts cast steel part and the liner is detachable. The turning gearwheel adopts casting hobbing process and the drum...
