Coal mill also called dual-rotor mill, two-stage crusher and so on, mainly for coal gangue crushing operations for other minerals also have a good effect, and today mainly speaking about Coal mill liner role, and liner wear and impact resistance properties. Coal mill is the use of crushed stone at stone materials, stone blacksmith carried principle, then in order to protect against wear and tear of the equipment rack origin cinder mill equipment to be installed on the Coal mill liner, which protects the device dry Wet cinder mill profiles, but also because a good replacement liner, you can always wear a replacement, without having to repair or replace equipment. Coal mill liners have two main functions, one of which is to protect the frame, which will help to replace, and the second is the liner above all have teeth that can crush crushed material than just improved. As the grinding process, different degrees of force parties to place a small cinder mill shows uneven wear is generally higher than the upper part of the lower abrasion wear faster, for more prolonged use, generally made of lining up and down symmetrical, Coal mill liner life depends on the material, the nature of the material, the mill operating parameters, feed uniformity, etc. Therefore, in medium-sized plants usually choose high-manganese steel mill liner system into this material, once crushed material, which will increase the surface hardness, wear resistance is relatively increased, has a certain toughness, can withstand impact load. At the same time, enhance the work of strengthening the hardness of gangue grinder, mill production capacity to improve and expand the application of market devices. Grand gangue grinder high wear-resistant liner manganese steel, you can better protect and crushing effect, with long time wear and impact resistance properties. Coal mill to discharge small, high yield is known, is to be as high fineness, high yield so wear wearing parts requirements are very high, so how to maintain gangue grinder accessories enable our customers to extend the life of the greatest returns. Factors that affect the life of gangue grinder has many mill, such as gangue grinder work long, poor working conditions, poor working conditions, in order to prolong the life of gangue grinder requires certain methods and techniques. So how to protect and extend the life of gangue crusher wear parts? First of all in the choice of gangue grinder, according to the nature of their chosen materials suitable mill. Such as large water containing materials, the material is easy to adhere to the content in coal gangue grinder also prone to clogging, crushing capacity is reduced. When the greater the viscosity of the material, the gangue crusher crushing capacity will be smaller. So according to the viscosity of the material, humidity, temperature appropriate to select different gangue grinder, so also to some extent reduce the gangue grinder wear parts to ensure gangue grinder life.
