1.PCH Series Ring Hammer Crusher owns the impact rotor with a special ring hammer. When the material enters into the crusher, it is crushed by the ring hammer which is revolved by the high-speed motor. At the same time the material obtains the kinetic energy and rushes to the impact plate receiving the second crushing. Then the material falls on the sieve and is cut, extruded, and grinded by the ring hammer and also further crush of the inter-grind among materials. At last the material up to the standard is discharged from the screen mesh. Material that can’t be crushed enters into the metal collector and should be cleared regularly.
PCH Series Ring Hammer Crusher is most suitable for crushing brittle materials such as coal, gangue, coke, slag, red sandstone, shale and loose limestone, etc. The compressive strength of the material should not surpass 100MPa. Moisture content is not more than 15%.

2.Application of Ring Hammer Crusher:
This series of ring-hammer crushers is suitable for crushing various materials of brittleness such as coal, gangue, coke, slay, shale and loose lime stone etc. Whose compressive resistance does not exceed 10Mpa and the surface moisture content should not be greater than 8%.

Ring Hammer Crusher Series Working Principle:
This series of machine is a punching rotor type crushing machine with ring-hammer on the rotor. First the material fed to the crushing space is crushed by punching force of the ring-hammer rotating at high speed. Mean while the material crushed gets kinetic energy from the ring-hammer and is punched forward the crushing board, and then it gets punched the second time and fall to the sieve plate. The material is cut, squeezed and crushed into pieces by the force of ring-hammer and their own rubbing and get out of the machine will be sent to the metal collector and get cleared off periodically.

3.This series of machine broke materials through the high-speed rotating hammer body and collision the material surface,it has a simple structure, large crushing ratio, high production efficiency and other characteristics,it can be used for dry and wet two forms crushing,it applies to mining, cement, coal, metallurgy, building materials, roads, fire and other departments chronology medium hardness and brittle materials. The device can change material particle size and adjust gap of article grate in accordance with user requirements, so it can meet different users’ demand.
  Ring hammer crusher characteristics:
This ring hammer crusher has simple structure,Convenient operation and maintenance,best-selling both in domestic and abroad,well received by users.
 Ring hammer crusher main purpose:
Ring hammer crusher for crushing all kinds of hard and abrasive weak materials. The material compressive strength does not exceed of 100Mpa, Moisture content is less than 15%. Broken material is coal, salt, chalk, gypsum, brick, limestone etc. it also can broke fiber structure,more flexibility and toughness of the broken wood,paper,waste of asbestos cement,recycling of asbestos fibers and so on. Besides, Hammer crusher can be used not only in broken production line,sand production line system,but also can replace the cone crusher in the mineral processing production line.
The main working parts of ring hammer crusher is the rotor with a hammer (or hammer),rotor is composed of spindle, disk, pin and hammer. The motor drive the rotor with high-speed rotation in the broken cavity,materials from the up mouth feeder into the machine,it is crushed by high-speed movement of the hammer blow’s impact, shear, grinding. Under the rotor, there is a screening plate, the crushed material whose size is smaller than the sieve can come out through the sieve, and the other material whose size is bigger than the sieve will still be combated and grinded by the hammer, finally through the plate out.
4.Ring Hammer Crusher is a kind of impact rotor type crusher with a ring hammer. Ring Hammer can not only switch along with rotor rotation, but also rotate around the hammer shaft pin. When material enters into the crusher, it can be crushed by the ring hammer which is revolved by the high-speed motor, at the same time material obtained the kinetic energy and rushed at the impact plate receiving the second crushing process, then falls on the screen sieve and be cut, extruded, and grinded by the ring hammer. At last the materials that come up to the standard can be discharged by the machine. Material can’t be crushed enters into the metal collector and should be eliminated regularly. Through replacement of sieve plate, discharge size of materials can be adjusted. Gap between rotor and sieve plate can be adjusted by the mechanism.
