Metal grinder is widely used in mining machinery and other industries, working conditions and wear-resistant parts of the machine are closely linked, so how best to extend the life of the crusher parts in tough it? 1, according to the machine broken material performance to match the right accessories harder the more difficult material stone crushing equipment wear more serious, the slower the rate of broken, crushing capacity is relatively smaller. Hardness degree and crusher parts directly related to the life of the stone surface, therefore, in the purchase of accessories, be sure to select the appropriate accessories based on the material properties of the material to be broken. 2. The material to be crushed humidity, viscosity, temperature and other issues, large selection of water of different crusher containing material, the material in the crusher content easy to adhere to, it tends to lower material conveying process blocked, resulting in crushing capacity decreases. And the greater the viscosity of the material, the crusher crushing capacity will be less. The humidity of materials to be crushed, viscosity, temperature and other issues, choose a different suitable crusher, jaw crusher, which also reduces parts wear to a certain extent, to ensure that the broken machine parts life. 3, product size also affects the smaller parts of the life of the finished product size requirements, the material in the crusher and contact friction the more the number of accessories, will also increase the degree of wear. Final particle size of crushed stone requires smaller, slower speed broken, the smaller the final impact crushing capacity. 4, the material to be crushed in the content of fines. Before crushing the material in more powder containing more impact crushing capacity, because fines during transport, easily attached to the belt, thus affecting the delivery of materials, a direct result of feed rate and feed rate of the crusher, crushing efficiency will be greatly reduced. For more fines content should advance once sieve; another stone contains more impurities, will affect crushing capacity. 5, metal crusher parts choose high quality, superior wear resistance of wear-resistant parts accessories need to choose the professional manufacturer of good quality can be used for a long time first, hammer crusher working principle of material falling from the feeding port into the crusher chamber, and high-speed rotation of the hammer collide, the crushed material with a quick hit in a certain degree of grate on the large size of the material after repeated crushing, after crushing the material to meet the requirements of small to exclude crack through the grate . Second, analysis of hammer crusher hammer wear during operation, in addition to being hit, but also by the erosion of materials, in this long-term repeated use, Fuxin crusher, hammer work surface would be destroyed, it is deformed, if the reversible crusher, hammer edges on both sides will be ground into a smooth arc surface. Third, the choice of traditional high manganese steel hammer wear hammer crusher hammer material is poor, life is short, large supplies. To this end, we will hammer hammer handle and the hammer is designed to end manufactured separately. Hammer handle part of the high manganese steel or carbon steel, hammer crusher, it has sufficient strength and toughness, high chromium cast iron hammer part. Fourth, structural design and manufacturing quality hammerhead structure design and geometry of the hammer inside its mechanical properties and phase structure of the alloy after heat treatment has a great influence. In particular thickness of big hammer, the impact is more prominent. By hammer Failure of different materials in the form of analysis, the cause of which was attributable to the hammer fracture or internal surface there are different degrees of impairment. Fifth, technical parameters Crusher hammer crusher will also affect the life, in which the main rotor power and speed. They not only related to the production capacity of the crusher, roll crusher, but also on the degree of hardening of the impact hammer. Good hammer shock hardening, its life will be extended. Sixth, the block of material and hardness of the broken piece of material, the higher its toughness requirements, while higher material hardness, the higher the hardness of the hammer material. Specific models crusher shall apply suitable feed size, which will extend the life of the hammer to a certain extent.
