The grinding process in ball mills and vertical roller mills differ fundamentally. In a ball mill the comminution takes place by impact and attrition. The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed, although the ...

Vertical roller mill is a kind of grinding machine for cement raw material, cement clinker, slag and coal slag. It has the features of simple structure, low cost of manufacture and use. Vertical roller mill has many different forms, but it works basically the same.
Vibration is simply a back and forth movement—or oscillation—of machines and components in motorized equipment. Vibration in industrial equipment can be a symptom, or cause, of a problem, or it can be associated with normal operation. For example, oscillating sanders and vibratory tumblers rely on vibration to function.

There's typically no way around it. At some time during a motor's life, it is likely to experience high vibration levels. What's behind this maintenance phenomenon? The cause may be an electromagnetic or mechanical imbalance, loose components, rubbing parts, bearing failure, or resonance. When a problem occurs, it is critical to quickly identify the source of the trouble and
