subject: Common Sense And Maintenance Of Rock Crusher [print this page] Stone crusher is commonly used in mine, melting, building, road, railway, water conservation and chemical industries. The most commonly used stone crushers are: jaw crusher, impact crusher, pneumatic selective crusher, hammer crusher, impact breaker, roller crusher and combined crusher. Characteristics of jaw crusher are: big reduction ratio, even granularity, simple structure, stable running, handy maintenance and economical operation.
In modern society, nothing can do without mechanical equipment. As a developing country with a vast territory and a large amount of population, housing and transportation become one of the most important issues. However, at present, the housing and transportation in China cannot meet the demand of people and the development of society. Therefore, Chinese government vigorously develops construction industry to meet the demand of people, and then develop the economy to meet the demand of society.

Generally speaking, the building stones are the most important part in construction industry. Without the building stones, the construction cannot exist any longer. However, the mountain stones are huge and hard. It is impossible to make the mountain stones into building stones with hand crushing. Therefore, the rock crusher, aiming at crushing the stone, becomes the right arm for construction industry. The rock crusher has many types. When crushing the relatively soft stone, the demand for the rock crusher is not high. The PF-I series of impact crusher processes materials with side length between 100-500mm and maximum compression strength of 350Kpa; the PF-II series of impact crusher is used for crushing of medium rigidity materials like limestone in cement plant.
The common breakdowns and solutions of Impact Crusher:
A, if crusher abnormally vibrates, it indicates that:
1, the material is too large, and then you can check the feeding size.
2, wear is uneven, which indicates the counterattack hammer needs to be replaced.
3, rotor is imbalanced, which indicates the rotor need to be adjusted.
4, foundation treatment is improper, and then we can check the anchor bolts and reinforce it.
B, if the bearings of impact crusher emit heat, it indicates that:
1, bearing is short of oil, so we need to timely add fuel; in addition, too much fuel also make the bearing emit heat, and we should check the oil level while refueling.
2, the bearing is damaged and we need timely replace bearings.
3, the top cover is too tight and we can regulate the bolts with an appropriate degree.
C, if the material particle size is too large, it indicates that:
1, the hammer is worn, and we should replace it.
2, the gap between hammer and impact plate is too large; we should adjust it to 15-20mm.
3, feeding particle size will also affect the size of discharging particle size.
In China, there are lots of rock crusher manufacturers. And there is no doubt that Henan Hongxing Mining Machinery Co., Ltd. is one of the greats. The rock crusher produced by Hongxing Company has obvious advantages, such as flexibility, working stability, high resistance to wear, easy to operate, and convenient to maintain. It is widely used in construction industry and gets high praise by its users.
