Customized Casting Steel End Cap Castings And Forgings Ball Mill End Cover
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.
When determining the journal part of the end cover, it must be considered in advance that the ball mill is driven by gears (straight teeth, helical teeth or miter teeth). Due to the horizontal error of the axis during installation, the ball mill may produce some axial forces during operation. Therefore, in order to prevent the cylinder from moving in axial direction under the action of axial forces and affect the normal operation of the gear, it is required to fix the journal. In this case, however, the possibility of expansion must be made possible, as the barrel extends as a result of heat, and as the load becomes difficult. Thus, of course, the two journals of the cylinder cannot be fixed at the same time, but only one can be fixed and the other is called the movable free end.
To achieve this purpose, a journal is usually designed with shoulders that are exactly equal to the length of the bearing bush; The other journal is not shouldered and made 5-25 mm longer than the bearing bush length. For the short cylindrical mill, any journal can be selected as the fixed end because the cylinder is not long. However, for the long cylindrical ball mill, the journal close to the gear ring must be selected as the fixed end. In this way, the deformation of the cylinder will not cause the gear to produce axial dislocation.
It needs to be pointed out that the two end covers of the ball mill are different, one is to the mine end cover, one is to discharge the mine end cover.
