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 the role of the ex-factory mill slag, and liner wear and impact resistance properties. Coal mill is the use of crushed stone at stone materials, stone blacksmith principle, then in order to protect against wear and tear of the equipment rack mill slag, gangue grinder want to install the liner, which protects the device, but also Because good liner replacement, 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 all places, wear is uneven, generally the lower wear than the upper wear faster, for more prolonged use, the upper and lower liners are generally made symmetrical, gangue mill liner life depends on the material, the nature of the materials, operating parameters mill, feed uniformity and the like, and therefore, the medium-sized factory mill liner is usually selected high manganese steel, 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, this device model variety, can be broken into a maximum feed size 200-800mm of 2mm or less, can be adjusted up to 1 cm, the fineness of this device can be adjusted according to user requirements. 1. For sintered brick mill slag small retail users, if the material is dry, you can use this gangue grinder to achieve the required fineness, speed more than 900 revolutions per minute, can achieve the purpose of crushing. 2. For the production of briquettes user cheap supply of slag grinder, you can use the small, 3-5 tonnes per hour production to meet daily production capacity, low investment costs, to a few thousand dollars. 3. For crushing ores, construction waste, coal users can also use the device, but users can only request is crushing our Coal mill also called Crusher. Requirements powder block inappropriate use of this device. 4. In response to the chemical class of materials, still also be crushed and crushed greater yield, because the hardness of these materials is not so hard ore. Therefore, it can be said gangue grinder is a versatile crushing crusher is suitable for all areas.
