Product Description

The barrel of the ball mill is a hollow cylinder, which is rolled and welded by several steel plates. The two ends of the barrel are connected to the hollow shaft by end caps. The cylinder has to bear the weight of the lining plate, grinding body, compartment plate and materials. It will generate huge torque when running, so it needs to have great bending strength and stiffness. Therefore, the cylinder needs to have sufficient thickness. This thickness is about It is 0.01 to 0.015 times the diameter of the cylinder. Larger ball mills need to be thicker. Simplified Chinese requires 1 to 4 grinding doors (related to the length of the ball mill and the number of bins) for replacement of lining plates, compartment plates, inverted grinding bodies and for personnel to enter the mill for maintenance. Opening the grinding door will reduce the strength of the mill, so the grinding door cannot be opened too large, and reinforced steel plates must be welded around the grinding door. As long as parts (lining plates, compartment plates or unloading grate plate parts, grinding bodies) and operators can enter and exit.

Product Performance

Working Principle

The main component of the ball mill is a cylinder with a small diameter and a large length. In addition to the cylinder, the structure of the equipment also includes the cylinder, feeding part, discharge part, transmission part, main bearing, circulating lubrication system, etc. .

During operation, the equipment is supported by rolling bearings and rotates slowly through transmission machinery. Materials are fed from the feeding end of the cylinder. In the cylinder, the materials are crushed due to the impact and self-grinding of the steel balls and the ore itself. Due to the continuous feeding of materials, the pressure causes the materials in the barrel to move from the feeding end to the discharging end. The slurry is higher than the lower edge of the hollow shaft at the discharging end and overflows by itself. The hollow shaft is equipped with anti-helical blades, which can return overflowing steel balls and coarse ore blocks into the mill.
