1. Work
Set on the rotor with the rotor speed rotary hammer plate kinetic energy when the impact of materials to make the material along its weak parts (bedding,
Cleavage) to selectively break; be the impact of material with great momentum, thrown by high-speed counter board, again by the red
Crushing blow, not chunks of broken boards and from the rebound to hammer back and continue to repeat the process. At the same time things in the back cavity
Material between the hit and broken; As the material by plate hammer blow, the impact of counter-plate collision between the material and,
Material constantly cracks, loose and further fragmentation.
2. Wear Mechanism
From the crusher working principle known, high-speed rotation of the plate material, while the impact hammer, hit the material with the same size
Strike force impact hammer, so the impact hammer to chisel cutting abrasive wear dominated. Material in different directions and plate hammer contact the board under hammer
Cutting abrasive wear. ,
3. The choice of materials
Hammer chisel to cut the impact of abrasive wear based, should choose materials with good toughness. A crusher for medium and large (fist for more than 1 250mm × 1 250mm), feed particle size greater than 400ram, impact force, should choose high-manganese steel, high manganese steel alloy. For in
Small Sec Crusher (Fist l 000mm × l 000mm or less), feed particle size is less than lOOmm, impact force is small, choose the
Carbon multi-alloy steel, high toughness, high chromium cast iron, service life than the high manganese steel can be increased by 100% to 300%, Figure
for the domestic production of the crusher of the hammer.
