impact crusher

impact crusher

【Capacity】:50-220t/h 【Feed Size】:250-500mm

【Power】:9.5-28.5KW 【Processible Materials】:Limestone, granite, coal, slag, clay, etc.


Stone materials fall from the upper end of the stone impact crusher directly into the rotary table. Under the high speed centrifugal action, materials have high velocity impact with flying stones at high speed and get crushed in high density. After materials are impacted from each other, they will move in eddy current between the turntable and the main case of the impact breaker, and then they have multiple striking, rubbing and crushing until they are discharged from the bottom tank.

Details Introduction of stone impact crusher:

1. this kind of impact crusher has High-quality plates and wear parts to reduce abrade and improve the production efficiency of various conditions; advanced processing technology is the basis of equipment performance.
2. Strong product commonality can reduce cost. Two-cavity impact crusher can becomes three-cavity machine by adding grinding racks, and no need to change other parts.
3. Heavy type rotor, finite element endurance analysis, optimized design, reasonable structure and enhancing moment of inertia lead to bigger crushing ratio and better abrasion resistance.
4. Static and dynamic balancing test for the welding rotor should be done before assembling. To make sure the rotor has a smoothly running and long working life.
5.Main shaft is finished by quality forging, adopts keyless design and world advanced cover tightening connection to ensure the reliable working and make the maintenance easier.
6.Unique locking device for hammers makes the tightening moment of force more safe and bigger. And the replacement of hammers can be more simple and convenient.
7.Standard design for liners increase the interchangeability, decrease the repertory and variety of liners.
8.Simple but practical locking device lock the shell 1 and shell 2 together. This device has a easy operation and saves locking time.
9.Unique hydraulic device design is convenient for opening the fame racks to replace wear parts and adjust the discharge size.
10.Simple structure for impact racks and grinding racks. Easy operation, long working life, convenient maintenance and low cost

principle and structure:

When stone Impact crusher works, under the driving force from motor, the rotor rolls at a high speed with the blow bar on it to make the material into small pieces, and then the material will be thrown toward the impact device and then to the blow bar, so it will be crushed again. This process repeats until materials are crushed to the requested size. The product size and output can be controlled by adjusting the clearance between impact plate and blow bar. This impact crusher is designed with spring safety device,when non-crushing material enter into crushing chamber, the impact rack will recede and then the non-crushing is discharged.it is controled automatic by PLC.
