Mining Customized Castings And Forgings Of 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.
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 |
