Impact Crusher,Impact Crushers for sale,Used Impact Crushing Machine,What is Impact Crusher,Impactor Crusher Machine Manufacturer

Impact Crusher Overview
Impact crusher (impactor crusher machine) is suitable for materials whose compressive strength is under 360Mpa, and particle size is less than 500mm. This kind of machine features easy maintenance, high crushing ratio and crushing efficiency etc. With end products in cubic shape, impact crushers are the ideal crushers for aggregates processing in high-type highway building, water conservancy and power construction.
Application area: road and railway building, dam, construction
Processing stage: secondary crushing
Crushing material: limestone, gypsum, talc etc. (<Moh’s harness 4)
Crushing ratio: 10-20
Main components: body frame, rotor, impact rack
Working principle: the rotor rotates at the high speed and hits the entering materials, which will be shot back by the impact rack; the material is crushed due to the constant impact
Protection type: impact rack self weight
Quickwear parts: high manganese steel, high chromium steel

Impact crusher application
Impact Crusher is the most common equipment of the stone crushing production line , adopting the latest producing technology, features many advantages: special structural design,cubic shaped desired products, dealing with the material with the side length 500mm, not more than 350Mpa anti-pressure strength,Impact Crusher can be widely used in crushing the coarse, midium, and fine material(E,g.granite,limestone,concrete).
Impact crusher main features and benefits
- 1. Energy-efficient.
- 2. Unique structure, keyless connection.
- 3. Blow bar made of high chromium steel, impact plate with a special shape.
- 4. End products with cubical shape.
- 5. Easy operation and maintenance and high reliability.

Impact Crusher Working Principle
The impact crusher uses plate hammer on the rapidly rotating rotor to generate high-speed impact to crush the materials in the crushing cavity, and casts the crushed materials along tangential direction to impact plate at the other end of the crushing cavity. The materials are crushed again, and then, they return to the plate hammer to undergo the process above repeatedly.
The materials are bumping with each other when being sent between the plate hammer and the impact plate. The materials become cracked, loose and then comminuted by knocking by the plate hammer, impact with impact plate and bump between materials. The materials with grain size smaller than the gap between impact plate and plate hammer will be discharged.
