Hammer crushers are of a progressive design that combines the advantages of impact crushers with those of hammer crushers. Crushers Liming are predominantly used for single-stage crushing of extracted limestone, dolomite, gypsum, limestone marl as well as other medium hard materials and materials that contain sticking clays and loams. As a rule, crushers OKD are used in the cement industry where ball mills are part of the grinding plant.

Hammer Crusher Operating Principle

The main working part of hammer crusher is rotors with hammer. The rotors consist of main shaft, disk, pin shaft and hammers. The motor drives the rotors to rotate quickly in the crushing cavity. Raw materials enter the crusher through the feed opening and are stricken, impacted, cut and ground by the high-speed hammer to small size. There is a screening plate under the rotor, so that materials with size smaller than the screen mesh will be screened out and others are left to be further hammered and ground until reach the standard size. The size of the final product can be adjusted by changing the screening plate. The gap between the rotors and the screening plate can also be adjusted according to different requirement.

Operating properties of hammer crushers

1. High operating reliability
2. Low cost for operating and maintenance
3. Long service life of main crushing elements
4. High specifi c throughput
5. Excellent degree of comminution
6. Favorable specifi c electric power consumption
7. Favorable grain size distribution of the product
8. Capability to crush even materials containing sticky components
9. Insensitivity towards non-crushable matters
