Ball Milll Inlet And Outlet End Cover Castings And Forgings For Mining Equipment
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.
2. Processing technology measures of ball mill end cover castings and forgings
| End cover and hollow shaft |
⑴ High quality cast steel ⑵ Large R rounded corners ⑶ High strength bolts are connected with the cylinder body |
⑴ Outside refining of molten steel furnace (argon blowing and R-H vacuum treatment) (2) The mold adopts special sand, strictly control pouring temperature and pouring speed (3) Journal processing to ensure the coaxiality and roughness of the end face stop |
⑴ Mechanical properties and chemical composition of casting blank (internal control standard) ⑵ Ultrasonic inspection after rough machining ⑶ Ultrasonic inspection and magnetic particle inspection after finishing |
