In the fine grinding operation of the ore, the quality of the casting of the end mill of the ball mill will directly affect the service life of the mill, so we must take it seriously when designing and casting the end cap.
In fact, the design of the end cap of the ball mill is relatively easy compared with the cylinder. In order to facilitate the design and assembly, we will bolt the cylinder directly around the end cap, so the radius of the end cap can be Directly designed as the radius of the barrel. In addition, because the ball mill does not require a high transmission type, we can connect the shaft directly to the end cover, which is convenient for positioning and also facilitates the production of the mill and the assembly of the equipment. When the ball mill is running, considering that the mixing of material and medium will produce great mass and impact force during this time, the shaft needs to bear a large radial force, so the diameter of the shaft cannot be too long, so after detailed The measurement of the axis should be Φ120 mm and the length of the shaft should be 130 mm. Since the end caps in production are relatively thin and still a round part, they are fixed by four ribs when connected, so the radial load they bear will be relatively small, then the material for the end cap casting The requirements will be relatively lower.
In general, from the economic and various aspects, the choice of cast iron as the material of the ball mill end cap is fully meet the needs of its production characteristics.
