Strengthen the inspection and maintenance of the equipment: Lubricating oil is one of the important factors affecting the equipment. According to the practical need of the equipment, we need put oil on each lubrication point. We also pay attention to the maintenance, because we can find many hidden trouble by this and deal with the trouble in time. We must inspect the crusher and record all kinds of data, then carries on the analysis summary, improving the shortage of the management of equipment so that extending the life of crusher.Strengthen the management of spare parts: The equipment is the basis of the production guarantee and premise condition, the reserving of spare parts is indispensable material in equipment management, the article parts all need to reserve.Doing the proper technical transformation and innovation: the technical reform and innovation will shorten the processing cycle, reduce the processing cost , guarantee the processing quality and extend the life of crusher.the size of material particle: we choose the different particle size of rock to test them, we can get the impact speed, from the analysis, we find that the greater diameter, longer impact time.the shape of material: the shape of material is different. Through the analysis, we find that if the shape of material is bigger, the impact will be longer. The same shape will have the same impact time. the wear of hammer: the wear condition is different, the impact time is not almost change, so it has less effect on the impact time.The impact time is the impact from the start to touch to the separation. This has a great influence on the structure, crushing efficiency ratio and the capacity of the crusher.Hongxing Brand is the China Famous Brand, and Hongxing believes that reliable and stable quality is the key to success.
