Ball mill end cover
The ball mill has two end covers, one is for feeding and the other one is for discharging.
Ball mill end cover is one of the key part of ball mill, its structure is relatively complex, long production cycle, high precision of processing and assembling, so when compiling process routes, should fully consider its manufacturability.
Ball mill end cover is slightly conical in general, which is considering the configuration of main bearing. Large and medium-sized ball mill end cover are mostly manufacturing by cast steel, the ductile cast iron is used for the small type ball mill. In order to ensure concentricity of the end cover axis and the cylinder axis, usually the end cover and shaft neck will casting together. But in the case of equipment ability is not enough, also can casting respectively, after processing fastening them together, and then to do mechanical processing.
1. Our ball mill end cover use standard wooden models, special core surface coating to prevent cracking, ensure the casting surface is bright and clean level off.
2. Our ball mill end cover use high quality steel scrap raw materials and auxiliary materials, and strict material composition test has be done before the production.
3. Our ball mill end cover do three sampling chemical test with Germany Spectrometer, to ensure that components qualified.
4. Our ball mill end cover use special heat treatment process, to increase the service life and the deformation ability.
