The solution to the problem of easy wear of the impact sand making machine

 Impact sand making machine is currently the most widely used sand making equipment on the market. It plays a very important role in the sand making production line. At the same time, everyone knows that the sand making machine is a piece of equipment that needs regular maintenance and repair. Repair, extend the life of sand making equipment and improve work efficiency

First, the influence of line speed. Linear speed is a working parameter that has a greater impact on the wear of the hammer. The reason is: the size of the line speed directly affects the impact energy of the blower on the material, the size of the crushing ratio, and the particle size of the product is decisive. In addition, excessive linear velocity may also lead to a sharp increase in the wear of the blow bar. This is because at too high a line speed, the material cannot enter the impact zone (or the depth of entry is small), and it is caused by severe abrasion at the end of the blow bar. of. Foreign research data show that: the wear of the blow bar is proportional to the linear velocity from the first to the second power.

The second is the influence of processing capacity and discharge gap. The processing capacity of the impact sand making machine also has a certain impact on the wear of the hammer. When the processing capacity increases, the product particle size will become coarser, the crushing ratio will decrease, and the unit pure abrasion of the hammer will also decrease. Similarly, changing the size of the discharge gap can also change the product particle size to a certain extent, so It also has a certain effect on the hammer wear.

There is also the influence of the nature of the material to be crushed. The impact of the material to be crushed on the wear of the hammer includes: the nature of the material, the size of the feed size and the water content, among which the nature of the material has the greatest impact. As can be seen from the table, corresponding to different crushed materials, The unit pure wear of the blow bars varies greatly.

The vulnerable parts of an impact sand making machine usually include a blower, a counterattack liner, a casing liner, and a rotor body guard. Among them, the wear failure time of the blow hammer is the shortest, and the wear cost is also high. Therefore, reducing the wear of the blow hammer is the key to solving the wear of the impact sand making machine.
