General Maintenance Methods The crusher is the most useful crushing machinery in mining industry. Crusher has the features of high efficiency processing, fine grinding refinement degree, so it is the essential part of various beneficiation production line!But it is just for this advantages that some common problems are always emerge.we all know that the crusher is widely used in mining, metallurgy, building materials, road, railway, water conservancy and chemical industry and many other sectors. Common crushing machines are winnowing mill, hammer breaker, breaker, roll crusher, crusher compound impact. Jaw crusher (jaw crusher), having large crushing ratio, uniform particle size, simple structure, reliable operation, easy maintenance, operating costs and economic characteristics. PF-I series impact crusher can process materials side length is 100 to 500 mm, the compressive strength is up to 350 MPa, great crushing ratio, cubic particles advantages of material was broken; PF-II series impact crusher machine, suitable for crushing hard materials, such as cement crusher, with a production capacity of the material advantages of small particle size. Based on our company several years s practice experience, we summarizes the following aspects of the failure and maintenance program: The first case is: bearing overheating Analysis of reasons: 1. Excess grease. 2.Grease is less 3. Filthy degenerate 4 grease. Bearing is damaged the solution: 1. Filling the proper amount of grease to the bearing greases should be 50% of the volume of its space. Cleaning bearings, replace grease 4. Replacement bearings Second case: the elastic coupling produces percussion Analyze the reasons: 1. 2 pin loose elastic ring wear solution: 1. Replacement elastic ring. Parking Tighten pin nut Third case: the coexistence is too large Analysis of reasons: 1. Hammer wear big 2. Sieve faults Processing approach: 1. Replacement hammer. Replacement screen bars The fourth case: reduced production Analysis of reasons: 1. Feeding uneven. Gap...
