The compound crusher is one kind of many crushers. The crusher refers to the machine that can produce final size of above 3mm. According to different working principle and the hardness of materials, there are some commonly used crushers, such as jaw crusher, impact crusher, cone crusher, compound crusher, roller crusher, hammer crusher, mobile crusher etc. Here is the introduction about compound crusher.
The compound crusher is the new high-efficiency crushing equipment that combines hammer crusher and impact crusher. It is a kind of perfect energy-efficient crushing equipment with large production capacity, high efficiency and big reduction ratio, which is widely applied in mining, construction and chemical industries. The compound crusher is ideally suitable for materials with high moisture content, because the finished sizes can be adjusted optionally; no grizzly bar is set so materials with much sand will not be blocked. The materials that cannot be broken will be discharged automatically once they enter the machine and will not damage the equipment. The compound crusher is of high efficiency, special structure, stable operation, low noise, easy maintenance and can be effortlessly changed wear parts after opening the door. These are the advantages of compound crushers. Then how does the compound crusher work?
The operation principles: The materials that fall into high-speed rotation impeller from the upper of machine bounce and break with the other surrounding umbrella-form matters at a high speed under the effect of high-rate centrifugal force. After the bounce, the materials will produce bump, friction and break repeatedly between impeller and cabinet. Then broken pieces will be discharged directly from the under part of the machine and they will form close-circuit time and again, finally be controlled by screening equipment to achieve the demanding final sizes.
During the process of using vertical compound crusher, people should get some safety knowledge. At first, people should check if the door of body is closed and let the machine stop gradually till be stable when open the door in case of danger. Then the crusher should start with loading nothing, the materials can be put into it after the machine operates normally. The feeding size of particles should meet the requirements; otherwise they will damage the machine. Next, if anything unusual happens in crushing process, people should stop immediately to review and the machine can reproduce after trouble shooting. Finally, people should add the lubricant oil to rolling bearings at regular time.
PF impact crusher used for mining crushing with low price features a unique combination of heavy rotor design, wear material and crushing chamber.
