Crusher produced by Hongxing Machinery has high crushing ratio

From different angles to the classification of wear, but more commonly used method is based on the mechanism of wear and tear damage. Generally can be divided into five categories: adhesive wear, abrasive wear, surface fatigue wear, corrosive wear, fretting wear. Erosive wear, adhesive wear and abrasive wear, which accounted for all the wear and tear caused by abrasive wear loss of more than 50%, mostly in the cement industry as the main wear of the abrasive wear mode.

The so-called abrasive wear - abrasion wear material means: abrasive or hard asperity interaction with the surface of the material loss caused during the process of surface. Such as equipment components and rock, sand, soil, clinker, coal, caused by friction between sports wear. Specific work environment is directly reflected in the various types of rock and rock mill grinder such as jaw crusher, crusher and ball mill and other machinery and equipment, such equipment will focus on various types of rock is crushed finely ground Therefore, to study this issue in Henan Acer based objects and important direction.

Abrasive wear by the stress and impact surface is divided into the size of chisel-type cutting abrasive wear, abrasive wear of high stress and low stress abrasive wear.

1, chisel-type cutting abrasive wear, such wear is characterized by a large impact, huge impact abrasive to cut into the metal surface, the friction surface of the chisel cut from under the large particles of metal, the surface was worn deep grooves and indentation. Such as rock crusher hammer and other parts of the surface of the wear and tear.

2, high-stress abrasive wear, such wear is characterized by high stress, the stress over abrasive abrasive crushing strength. Crushed abrasive particles were polygonal, scratch the metal, leaving grooves in the friction surface and the pits. Such as rock crusher jaw plate so the surface damage.

3, low-stress abrasive wear, such wear is characterized by a low-stress, abrasive surface stress acting on the friction does not exceed the crushing strength of its own. Material surface scratches and a tiny cut marks. Drunk sand pump impeller wear.

Friction surface material shedding or transfer the phenomenon known as wear and tear. Wear process is multifactorial complex process of mutual influence. In addition to the characteristics of the material itself, but also with the form of friction, surface, conditions of use (such as pressure, speed, temperature) and so on. The result of the friction wear surface of a variety of different forms of damage, and thus correspondingly different forms of wear.
