Causes and Treatment Measures for Serious Wear of Grinding Roller of Raw Gold Processing Milling Machine

In the crushing process of the Raw Gold Processing Milling Machine, the grinding roller, which is a key wearing part, is prone to severe wear, thereby reducing the service life of the grinding roller and the working efficiency of the Raw Gold Processing Milling Machine. The following is a detailed analysis and introduction of the causes and treatment measures of the wear of the grinding roller.

cause of issue:

Roller wear is the main failure mode of Raw Gold Processing Milling Machine. Generally, the service life of the grinding roller is short and the consumption is large. It is necessary to reserve a large number of spare parts to maintain normal production and high production cost. There are two reasons for the short service life of the grinding roller: First, improper selection of the roller material. The grinding roller material is often made of high manganese steel. The high manganese steel is characterized by good toughness, high strength, good manufacturability and certain hardness. Under the action of large impact or contact stress, the surface layer of high manganese steel will rapidly produce severe Work hardening greatly improves surface hardness and wear resistance. However, in actual use, the impact force or the contact stress is often insufficient, and the surface cannot be quickly hardened by work hardening, and the wear resistance cannot be fully exerted. Second, the selection of the roller structure is improper. There are many types of Raw Gold Processing Milling Machine grinding rolls. The working surface is thick and narrow. The wide and effective wear is large. There are single-head work and double-head work. There are single-sided work and double-sided work. The head has only one wear surface, two wear surfaces on both ends, and four wear surfaces on both sides. The grinding roller with a large effective wear amount and a large number of wear surfaces under the same material has a long service life.

Treatment measures:

To improve the service life of the Raw Gold Processing Milling Machine, it is possible to scientifically select the material of the grinding roller and optimize the structure of the grinding roller. In order to improve the service life of the grinding roller, the grinding roller of the Raw Gold Processing Milling Machine should select some materials with better wear resistance, such as high chromium cast iron and low carbon alloy steel. High-chromium cast iron is a material with excellent anti-wear properties, and its wear resistance is stronger than that of high-manganese steel. The disadvantage is that the toughness is low. In the case of large impact, brittle fracture is easy to occur. In order to improve the strength of the grinding roller and reduce the cost, a layer of high chromium cast iron can be welded on the high manganese steel grinding roller to achieve wear resistance. Low-carbon alloy steel is mainly alloy structural steel containing various elements such as chromium and molybdenum. It has high hardness and good toughness. Under the same working conditions, its service life is at least doubled than that of high-manganese steel hammer, but quenching and tempering. The heat treatment process is the key. In the structure selection of the Raw Gold Processing Milling Machine grinding roller, under the conditions of the process conditions, the structure of the wide and thick working face and the double-headed double-sided working roller can be selected, which can greatly improve the service life of the grinding roller.
