Crusher is a crushing machine used in the processing of metallic and non-metallic ores and can crush the mined raw ore into small pieces by extrusion and bending.
What types of crushers are there?
What is the working principle of the jaw crusher?
What are the most common mistakes and repair methods of heavy hammer crushers?
There are many different crusher models, each with its own performance advantages, different production requirements and different end product quality. For several commonly used crushers, some data are listed below for reference:
1. Jaw crusher:
The jaw crusher imitates the chewing movement of the two jaws of animals, complies with ecological mechanics, has a simple structure and a scientific and reasonable working principle. It is a commonly used device model for coarse crushing.
2. Cone crusher:
Cone crushers are used for secondary crushing, cone crushers can be divided into single cylinder hydraulic, multi cylinder hydraulic, composite cone crusher and so on. Hydraulic overload protection ensures safe production and avoids wear inside the plant. The suitable production mode can be selected according to the actual production requirements.
3. Impact crusher:
The impact crusher is a secondary crusher. Using the principle of impact crushing, it can cooperate with the coarse crushing plant in the crushing and sand making production line to complete the crushing of the stone.
A jaw crusher works just like an animal chewing food, except that it chews the material to be broken. The motor drives the belt and pulley, and the eccentric shaft moves the movable jaw up and down. As the movable jaw lifts, the angle between the toggle plate and the movable jaw becomes larger, thereby pushing the movable jaw to approach the fixed jaw. At the same time, the material is shredded or chopped to achieve the shredding purpose. When the movable jaw lowers, the angle between the toggle plate and the movable jaw becomes smaller, the movable jaw leaves the fixed jaw under the action of the spring and the pull rod, and the crushed materials are discharged from the lower opening of the crusher chamber.
If the impact crusher is found to vibrate abnormally:
1. If the material is too large, you can check the feed size.
2. Uneven wear indicates that the hammer must be replaced.
3. The rotor is unbalanced and needs to be adjusted.
4. If the foundation is not handled properly, the anchor bolts must be checked and reinforced.
If the bearing of the impact crusher is hot:
1. It means that the bearing has too little oil and needs to be replenished in time. Too much oil naturally leads to a heating of the bearing. Be sure to check the oil level when refueling.
2. If the bearing is damaged, replace the bearing in time.
3. The top cover is too tight and the screws should be well adjusted and the strength is reasonable.
