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, in order to protect it from wear and tear of equipment racks to be installed on the Coal mill liner, which protects the device, but also because the liner Good replacement, has worn can be replaced at any time, 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 gangue grinder high yield, to varying degrees by the force of gangue grinder all places, wear is uneven, generally the lower wear than the upper wear faster, for more prolonged use, lining generally made up and down symmetry, Coal mill liner life depends on the material, the nature of the material, the mill operating parameters, feed uniformity, etc. Therefore, in medium-sized plant mill liners usually Choose high manganese steel, a material once crushed gangue material mill, low energy consumption, which will increase the surface hardness, wear resistance is relatively improved, has a certain toughness, can withstand shock loading. At the same time, enhance the strengthening of high hardness Coal mill Coal mill work life, improve mill production capacity, expanding 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. "Equipment Improvement" stone coal rod mill has replaced the early single-stage grinder sieve bottom, the perfect solution humidity broken material difficulties. At present, I made Yufeng coal rod mill stone unique design, simple operation, excellent workmanship, all processes are to undergo safety testing before approving the relevant departments factory. Coal rod mill is sintered brick stone crushing best device that high output, low noise, high fineness. Equipment package for easy maintenance and no special installation immediately start to use, you can control the fineness of coal rod mill stone minimum fineness can reach 3mm below about 90%, 2mm below about 80%, mainly the unconditional return.
