Hammer crusher / primary hammer crusher / coal hammer mill crusher
Hammer crusher: primary or secondary Rock crushers . It is used for crushing raw materials that have compressive strength less than 150MPa such as limestone, marl, sandstone, gypsum, coal, etc. The single stage hammer crusher can crush the ore block at the stope into the granularity required at a time. It can replace the traditional two-stage crusher and help simplify process flow, save infrastructure investment and production costs.

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 by more than one time.
3. The AMC alloy hammerhead enjoys a service life increased by 50~150%. 4. The military high strength artillery steel spindle is designed with vacuum duplex which increases the strength by 3-4 times.
