The grinding operation of the intermittent ball mill is carried out in a simplified system. When the cartridge is rotated, it is raised and rises to a certain height, and the gravity of the steel ball itself is dropped along a certain track. The steel ball in the region is subject to the role of two power: one is applied to the steel ball in the tangent direction during rotation; one is opposite to the steel ball diameter and the force is opposite to the above force, this force The generation is caused by the sliding movement of the steel ball itself.
The above two functions, for the steel ball constitute a pair of power, since the steel ball is extruded in the middle of the barrel and adjacent steel balls, the force will make the steel ball between the steel balls The frictional force, the steel ball with the cylindrical shaft, and the area is thrown in the region, in the region, in the region, the ore in the body has a powerful impact, and the ore is broken. Therefore, the ore in the ball mill body is mainly affected by the effects of earth-bearing, impact strength, and extrusion.
When the intermittable ball mill bearing is designed, the hydraulic bearing is highly developed. The static pressure bearing is before the mill starts, and the high pressure oil is in the bottom of the bottom of the bearing, forcing the shaft to float in the bearing, thereby forming a intact lubricating oil film at the shaft and the bearing contact surface to ensure the shaft in any speed and load. In the case of a fully liquid lubrication, the operation continues to maintain high pressure oil. The moving static pressure mixing bearing is a high-pressure oil, moving, and static pressure system simultaneously on the original pressure bearing to solve the launch problem of the mill.
When the grinder is started, the batch ball mill can also be cut off, and the high-pressure oil can also be cut to operate in the dynamic state. Therefore, the hydraulic bearing has the advantages of large load capacity, small starting torque, less wear, high operating precision, has gradually been promoted in the grinder. Sliding bearings with rolling bearing have been successfully applied, and the advantage is that the stress is small in size, the hollow shaft, end cap and the cylinder is small, and the automatic dry oil lubrication system can be used. The ball bearing is also automatically calm, and its power consumption It can reduce 6% and the maintenance costs are also greatly reduced.
