Problems that should be Noted when Researching Vertical Shaft Impact Crusher

Since being launched, vertical shaft impact crusher has been playing a very important role and widely used in many industrial departments. Especially with the fast development of the economy and infrastructure construction, it becomes even more important. For this reason, people never stop the research on this crushing machine. Then what should be noted when researching and developing vertical shaft impact crusher?

(1) The problem of abrasion.

Reducing the abrasion rate is the top priority of mining crusher manufacturing companies. The main anti-abrasion spare parts of the vertical shaft impact crusher include polishing head, anti-abrasion clamping block, upper and lower anti-abrasion plate and the feeding socket and the changing rate of the spare parts is very high, which will produce big influence on the production of the crushing machine. At present the main methods of reducing the abrasion are casting anti-abrasion materials on the surface of the easy-wearing parts and replace new materials for the original parts. However, all these methods start from the materials, and abrasion is also related to the workload, rotary speed, grinding media and the structure of the machine, which needs more research and attention.

(2) The problem of granularity distribution of the product.

One of the major features of the vertical shaft impact crusher is that the final products are good shaped, but its crushing ratio is relatively lower compared with cone crusher, so that it can only be used in the third and fourth crushing recycling. The granularity distribution of the final products is related to the self property of the crusher, working parameter, the feature of the materials, production cost and the abrasion factors, so that the experts of the mining machinery manufacturing companies can provide theoretical basis for effectively reducing abrasion and optimizing the granularity distribution of the products by way of analyzing the abrasion rate of the crushing equipment and the product granularity distribution.

(3) Fault analysis and control.

In the actual production, it is necessary to more effectively and proactively predict the faults that may happen to the crusher and control the malfunctions, learn about the abrasion principle of the easy-wearing parts and figure out the reasons and parts of the malfunctions in a faster and more exact manner.
