Hammer crusher

Hammer crusher

Hammer crusher for crushing all kinds of hard and abrasive weak materials. Compressive strength of the material does not exceed 100MPa, moisture content less than 15%. Material to be broken coal, salt, chalk, gypsum, brick, limestone and so on. The main working parts ring hammer crusher rotor with a hammer (also known as hammer) of.

Hammer crusher is directly 600-1800 mm maximum particle size of the material crushed to a period of 25 or 25 mm below the crushing crusher. Hammer crusher is suitable for cement, chemicals, power, metallurgy and other industrial sectors crushing medium hardness material, such as limestone, slag, coke, coal and other materials in the debris and crushing operations.Service Online >

hammer crusher Works

Hammer crusher works mainly by broken material impact energy to complete the job. When the hammer crusher work, the motor drives the rotor for high-speed rotation, uniform material into the crusher chamber, high-speed rotary hammer impact, shear tearing the material cause material to be broken.

At the same time, the material itself by gravity toward the frame so that the material body baffle, screen bar from the high-speed rotation of the hammer, sieve size larger than the material retained on the sieve continue to be a hammer blow and grinding until crushed to the required Finally, the expected size from the plane through the sieve.

Hammer crusher to rely mainly on the impact of the role of broken material. Crushing process roughly like this, the material into the crusher, hammer-speed rotation of the impact suffered broken, broken material, obtained from the kinetic energy of the hammer from high speed toward the body of the bezel frame, grate bar, hit each other at the same time the material, was repeatedly broken, smaller than the gap between the screen bar material discharged from the gap, the larger the individual materials in the screen bars again after hammer impact, grinding, extrusion and crushing, hammer material is extruded from the gap, thereby obtaining the desired particle size of the product.

Hammer crusher is applied to crushing coal

Hammer crusher is directly 600-1800 mm maximum particle size of the material crushed to a period of 25 or 25 mm below the crushing crusher. Hammer crusher is suitable for cement, chemicals, power, metallurgy and other industrial sectors crushing medium hardness material, such as limestone, slag, coke, coal and other materials in the debris and crushing operations.

Coal crusher into being after high-speed rotation of the ring hammer impact action was broken early, early speed toward the broken pieces of coal and sieve plate, was hit again, but also with each other between the coal strike, followed by small coal block on a sieve again by rotating ring hammer crushing, shearing, roll grind, grind, so that after crushing the coal from the plane, not the broken debris, such as iron, etc. from the sieve, and dialed the rotor iron into the room.

Hammer crusher precautions when using

  • feeding should be uniform, and the total length of the rotor should be covered, otherwise broken plate, sieve will appear uneven wear phenomenon, affecting their life, and prone to clogging and uneven discharging granularity.
  • When the ring hammer excessive wear, the efficiency is low, replace the ring hammer.
  • When the coal crusher after startup, the rotor speed reaches ratings before slowly to the coal, and then gradually increase the rating.
  • is not allowed to start with a load.
  • do not allow to increase the rotor speed.
  • hydraulic system oil should be clean enough oil should be cleaned once before installation. Starts running, every three months to replace a second oil, after six months can be changed once oil.
