Factors for Service Life of Bearing in VSI Crusher

In general, for the bearing of VSI crusher, its service life is initially set at from 30,000h to 40,000h. According to the service life and diameter axle, we select the corresponding bearings. Since bearing bears the axial load and radial load at the same time, we need to turn the actual load into equivalent dynamic load.

Load is classified into process load and non-process load. Process load refers to the load on building material, structure and component. For non-process load, it means the natural load like wind load or snow load on building structure. More detailed, process load is classified into using load and installing load.

Using load means the everlasting load on machines and structure. In another aspect, load is divided into dynamic load and static load. Static load is the load on static machine while dynamic load refers to the additional load on working machines. Vertical VSI crusher has developed to vertical synchronous crusher.

To take full use of crushing power, decrease the working speed and strengthen the effect of tertiary crushing, we integrate two crushing cavities together. At present, there are many suppliers of sand making plant in China and most of them like imitating. The manufacturing level of Chinese suppliers is far away from those of foreign advanced.

To improve the technical content, we work with the groups like universities, scientific research center or technological agencies. Interested in the price of sand making plant? Click website to download the latest price list!
