The sand making machine is also called the vertical shaft impact crusher. It is a common equipment in the sand making production line. It plays an important role in the sand making production line. However, the wear of the sand making machine also causes headaches for many customers, and regular maintenance and maintenance becomes Especially important, Zhongxin technical engineer gives you a brief introduction to the factors that cause the sand machine to wear.
First of all, the influence of the line speed, the line speed is the working parameter that has the greatest influence on the hammer wear. The reason is: the magnitude of the linear velocity directly affects the magnitude of the impact energy exerted by the hammer on the material, the size of the crushing ratio, and plays a decisive role in the particle size of the product. In addition, excessive line speeds may also lead to a sharp increase in hammer wear, because at too high a line speed, the material cannot enter the impact zone and is caused by severe wear on the end of the hammer.
Secondly, the influence of processing capacity and discharge gap, the processing capacity of the impact sand making machine also has a certain impact on the hammer wear. When the processing capacity is increased, the product grain size will become coarser, the crushing ratio will decrease, and the unit pure wear of the plate hammer will also decrease. Similarly, changing the size of the discharge gap can also change the thickness of the product to some extent, so It also has a certain influence on the hammer wear.
Finally, the influence of the properties of the material to be crushed, the influence of the material to be crushed on the hammer wear includes: the nature of the material, the size of the feed, the size of the feed and the water content, etc., and the influence of the nature of the material is the largest, from the table It can be seen that the unit pure wear of the plate hammer differs greatly for different crushed materials.
