Knowledge is Power!
We may have some knowledge of some equipment, take example of ball mill, having worked for a long time, the length of ball mill cylinder will change, and still there is a significant difference; the reason is that the temperature of cylinder changes when the ball mill operates, the temperature change cause the expansion and contraction. Although the material requirements of the ball mill barrel are relatively high, in the perennial production process, the cold and heat changes in barrel may causes a ball mill deformation. Since this situation is inevitable, then what can we do to make some design not affected by the ball mill works? For this topic, we are carrying out the following discussion.
We all know that some parts of the ball mill cannot be moved, such as some engagement between the gears; when they move will make the production stagnate, production activities would be unable to carry on, so we must think of a way to solve it. The deformation due to thermal expansion and contraction is called axial thermal deformation; and we can regulate it by the following ways:
1. Leave some voids between the shaft position and the bearing position in some of the hollow shaft. This flux would have some buffer area; some devices will not be directly affected.
2. Install some steel roller between bearing seat and floor. When the cylinder changes, the base can move along with the steel roller to make the whole ball mill be flexible.
What we said above provides some buffer; In fact the whole ball mill equipment is like a personal, buffer is indispensable; with buffer, device seems to have vitality, production activities will be more effective. What we introduce is just part of the adjustment knowledge, and I hope we can carry out some small transformation.
