Reasons of Vertical Roller Mill Vibration
The materials are too fragile. For some fragile materials, when they enter into the grinding mill, they will be broken down under the grinding function of vertical roller mill and it can cause the breaking material phenomenon. There is no material under grinding roller, the roller will crack on the millstone and make the machine vibration.

Inclined Planes - Physics Classroom
An object placed on a tilted surface will often slide down the surface. The rate at which the object slides down the surface is dependent upon how tilted the surface is; the greater the tilt of the surface, the faster the rate at which the object will slide down it. In physics, a tilted surface is called an inclined plane. Objects are known to accelerate down inclined planes because of an ...
