Jaw plate usually mad of high manganese steel, medium manganese steel, high chromium cast iron, medium carbon low alloy cast steel, etc. High manganese steel jaw plate

Since the moving jaw plate and the fixed jaw plate both are subject to squeezing and friction, the material of the jaw plate should be hard enough and resilient as well so that the jaw plate can have good impact resistance.

As a kind of alloy steel material, high manganese steel, a recasting manganese steel alloy, is named after high manganese content. The manganese content is controlled within a range to ensure that the manganese steel alloy not only has good hardness and wear resistance, but also has good resilience. Medium manganese steel jaw plate

The jaw crusher as a primary breaker has a wide range of use, so the materials to be handled are complex and the working environment is relatively harsh. In this way, more materials of the middle jaw plate are required to cope with different working conditions and the jaw plate can reach the best working state . For example, chromium (Cr) and other elements are added to the manganese steel alloy to improve the performance of the manganese steel. Medium manganese steel is to reduce the corresponding manganese content in the manganese steel alloy, while adding other elements to improve its wear resistance. According to relevant experiments, the actual service life of medium manganese steel jaw plate is about 20% higher than that of high manganese steel jaw plate, and the cost is equivalent to high manganese steel.

High chromium cast iron jaw plate

The high-chromium cast iron jaw plate has high wear resistance, but the toughness is poor, so it has poor effect directly used as the material of the jaw plate. However, some factory will adopt composite processing skill when making the jaw plate. The principle is to combine high chromium cast iron with high manganese steel jaw plate to maintain high wear resistance and good toughness. Although the service life of this kind of jaw plate has been significantly improved, the manufacturing is relatively complicated and the cost is relatively high.

Medium carbon low alloy cast steel jaw plate

The medium carbon low alloy cast steel has relatively strong hardness and moderate toughness, so it can cope with the requirements of the jaw plate under different working conditions. So this material is used in a certain range.

In summary, the manufacturing of jaw plate is to add various elements to the alloy steel to improve the wear resistance and toughness requirements of the alloy steel. However, the ideal state is often not achieved at the same time in reality. Therefore, in the actual selection of equipment, it is necessary to fully understand the material selection of the equipment and its own actual working conditions, thus to select the appropriate equipment material to improve equipment efficiency, production output and service life.
