Vertical roller mill is the grinding equipment after crushing operation and the main equipment to realize the dissociation of mineral monomers.

Therefore, the operation cost of vertical roller mill accounts for a very large proportion in the whole concentrator. In case of failure, it will often have a great impact on the concentrator.

Generally, there are two main causes of vertical roller mill failure. On the one hand, there are inherent factors.

Due to potential defects in the structure of the equipment itself, there are defects in the components of the equipment; The equipment quality is low due to the lack of material; Imperfect transportation and installation, potential defects brought to the equipment, etc.
