Working Principle of Ring Hammer Crusher：

Ring hammer crusher mainly makes use of the impact effect to crush materials. The crushing process is roughly like this: when the materials enter the crusher, they are crushed by the high speeding ring hammer. The crushed materials gain energy from the ring hammer, rush to the crushing board at high speed, and crashed at second time. At the same time the materials bump with each other, and are repeatedly cracked. The material smaller than the grate bar gap are discharged, while larger ones on the grate bar are impacted, grinded, squeezed again to be crashed by the hammer, at last the materials are extruded by the hammer from the gap to obtain products with the required size.
The motor transmits power through belt, drives the moving jaw to do periodic motion towards the fixed jaw by the eccentric shaft. The angle between toggle plate and moving jaw plate increases when moving jaw moves . So the moving jaw moves towards the fixed jaw. The stuff will be crushed in this process. The angle between toggle plate and moving jaw decreases when moving jaw moves down, the moving jaw moves leaves fixed jaw by pulling rod and spring, the final crushed stuff will be discharged from the outlet.

Working Process of Ring Hammer Crusher：

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. 

Characteristics of Ring Hammer Crusher:

• A kind of impact rotor type crusher with a ring hammer;
• Widely used in stone mining, metallurgy industry, building material, highway, railway, and chemical industry；
• Crushing ratio of 4-6 and the shape of final product is even；
• To crush high hardness, mid hardness and soft rocks and ores.
