Solution to the problem of easy wear of impact sand making machine
The 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 worn-out equipment that requires regular maintenance and repair. Repair, extend the life of the sand making equipment, and improve work efficiency. So what are the factors that cause the impact sand making machine to wear? Let’s answer for everyone.
First, the influence of line speed. Linear speed is a working parameter that has a greater impact on the wear of the blow bar. 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 it plays a decisive role in the particle size of the product. 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 wear at the end of the blow bar. of. Foreign research data shows that the wear of the blow bar is proportional to the linear velocity from the first to the second.
The second is the influence of processing capacity and discharge gap. The processing capacity of the impact sand making machine also has a certain influence 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 some extent. It also has a certain impact 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. It can be seen from the table that corresponding to different crushed materials, The unit pure abrasion of blow bars varies greatly.
The vulnerable parts of the impact sand making machine usually include the hammer, impact liner, casing liner and rotor body guard. Among them, the wear failure time of the blower is the shortest, and the wear cost is also high. Therefore, reducing the wear of the blower is the key to solving the wear of the impact sand making machine.
