Hammer crusher

Hammer crusher which the compressive strength is less than 150MPa is used for crushing raw materials, such as, limestone, marl, sandstone, gypsum, coal, etc. The Single Stage Hammer Crusher can crush the ore block at the stope into the  required  granularity at a time. It can replace the traditional two-stage crusher and help to simplify process flow and save infrastructure investment and production costs.

The Hammer Crushers break rock by impacting the rock with hammers that fixed upon the outer edge of a spinning rotor. The practical use of hammer crushers is limited to soft materials and non-abrasive materials, such as, limestone, phosphate, gypsum and weathered shales.
The main working part of hammer crusher is rotates 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 then they are stricken, impacted, cut and ground by the high-speed hammer to small size.
There is a screening plate under the rotor. The materials smaller than the screen mesh will be screened out and others are left to be further hammered and ground until they 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.
 Hammer Crusher Features:
1. The enhancement rotor is designed with finite element analysis technology.
2. The WHM two-step method hard surface deposition technology increases the surfacing life;

3. The AMC alloy hammerhead increases the service by 50~150%.
4. The military high strength artillery steel spindle is designed with vacuum duplex which increases the strength by 3-4 times.
