What are the wear factors of the impact sand making machine in production? Sand making machine is widely used in sand making production line, and it is the main equipment for artificial sand making of river pebbles, granite and pebbles. With the improvement of market demand for machine-made sand, the demand and requirements for sand making machines are also getting higher and higher. Although the design of the sand making machine is gradually improving, wear and tear will inevitably occur during production. What causes the sand making machine to wear?
1. The influence of linear speed.
The line speed is the working parameter that has the greatest influence on the wear of the blow bar. Because the size of the line speed directly affects the size of the impact energy exerted by the blow bar on the material, the size of the crushing ratio, and plays a decisive role in the particle size of the product. In addition, excessive linear speed may also lead to a sharp increase in the wear of the blow bar, because at an excessively high linear speed, the material cannot enter the impact zone (or the depth of entry is very small), and it is caused by severe wear at the end of the blow bar. of. Foreign research data show that: the wear of the blow bar is proportional to the first power to the second power of the line speed.
2. 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 blow bar. When the processing capacity increases, the particle size of the product will become thicker, the crushing ratio will decrease, and the unit pure wear of the blow bar will also decrease. Similarly, changing the size of the discharge gap can also change the size of the product particle size to some extent, so It also has a certain impact on the plate hammer wear.
3. Influence of the properties of materials to be crushed.
The influence of the material to be crushed on the wear of the blow bar includes: the nature of the material, the size of the feed particle 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 plate hammer The unit pure wear of hammers varies greatly.
