Wear factors of hammer head in hammer crusher

1.Influence of linear velocity

Linear velocity is the working parameter that affects the wear of hammer head. The linear velocity directly affects the size of impact energy, crushing ratio and particle size of the product. In addition, excessive linear velocity may lead to a sharp increase in wear of the hammer head, which is caused by the excessive linear velocity, the material can not enter the impact zone, and the end of the hammer is severely worn out.

2.Effect of treatment capacity and discharge gap

The processing capacity of the equipment also has a certain effect on the wear of hammer head. When the processing capacity increases, the product granularity will become coarser, the crushing ratio will decrease, and the unit wear of hammer head will also decrease with the increase of processing capacity. Similarly, changing the size of discharging gap can also change the grain size of the product to some extent, so it has a certain effect on the wear of hammer head.

3. Effect of properties of material to be broken

The influence of the material to the hammer wear includes the properties of the material, the size of the feed material and the water content, etc. Among these factors, the more hardness of the material, the greater the wear of the hammer head.

4.Improper operation

As the hammer is often broken, the workload of the maintainer to replace the hammer is large and the labor intensity is great. Therefore, after the new hammer is installed, it is not checked in time, which makes the bolt loose and not fastened in time. As a result, the hammer wear faster.
