Coal crushers mostly consist of impact crusher, ring-hammer-type crusher, etc. In the crusher, using the run-up hammer blowing, materials fly to effect plate as high speed, influence, and reverse impact. Meanwhile, components effect and crush with other in cavity, aspect of the components get reduce by the action of strike blade and effect plate. With bad controllability, this system will make huge coal ash; it's even worse for coal of low hardness and high brittleness.
1. Constant attention should be paid to the timing lubrication of friction surface. The lubricating work of impact crusher should be determined according to the location, temperature and other conditions of the crusher. In general, Construction waste crushing processing plant in USA calcium, sodium base grease can be adopted.
2. After eight working hours, the inner bearing should be lubricated for one time, and every three months, the lubricating grease should be replaced after cleaning the bearing carefully with petrol or kerosene. Then add the grease for the 50% of the bearing capacity.
3. There are many ways to add lubricating oil. Use the grease gun to lubricate the bearing, or the concentrated lubricating oil adding method. There is also permanent lubrication method and so on. During the selection of lubricating oil, specific approaches need to be considered in the lubrication process.
4. If the vibration of the impact crusher is relatively large, you can choose high viscosity and lubrication oil with adhesion and anti vibration effect, which can reduce the vibration effect on the lubrication result.
5. Choose the type of lubricating oil reasonably. Copper crusher and dressing equipment sale in Chile When selecting or changing the type of oil, you should consider the wear degree of the crusher. If the wear of the component is serious, viscous oil should be adopted. If one kind of lubricating oil will replace another, you can make a decision according to the main quality index —...
