Ball Mill End Cover Castings And Forgings ZG270—500 Cast Steel End Cap

1. Introduction of ball mill end cover castings and forgings

The end cover of the ball mill is one of the main parts of the ball mill produced by our factory. End cover material is ZG270-500.

The strength of the dangerous section of the ball mill end cover is the first problem to be considered in the design of the end cover, because the rather heavy ball mill barrel is supported on the main bearing by the end cover.

The ball mill end cover is generally slightly conical, which is designed to take into account the configuration of the main bearing, the bending resistance of the journal and the problem of avoiding big gear touching the foundation of the main bearing. The end cover of large and medium-sized ball mill is mostly made of cast steel, while the small ball mill is made of ductile iron. In order to ensure the concentricity of the axis of the end cover and the cylinder, the end cover and the journal are usually cast into one. But in the case of smelting and casting equipment capacity is not enough, they can also be cast separately, after processing, they are fastened together, and finally mechanical processing.

3. Ball mill inlet and outlet cover castings and forgings

The structure of the end cover of the ball mill is generally divided into two categories: integral type and split type. Integral generally refers to an integrated, integral casting; And the main consideration of the separation of the lifting, transportation and other factors will be divided into two lobes, four lobes or even more lobes.

Split flap end cover

The end cover is generally composed of two valves, four valves and even multiple valves, but the majority of two valves. The general technological process is: scribing - rough milling joint surface drilling handle hole closing - fitting the assembly round, rough milling joint surface each machining surface - disassembling the fine milling joint surface, drilling and reaming each hole closing and positioning pin control to meet the drawing requirements, the drawing requirements of the fine lathe all surface to meet the drawing requirements, the drilling flange and cone surface each air to meet the drawing requirements. (The specific size of the flap number that divides according to end cover place even and end cover is arranged once or many times semi-finishing). Because it is the end cover of multi-lobe, so the key is how to control the deformation of the joint surface and the processing of the closing hole and the positioning pin hole and the thickness of the inner and outer cone surface.
