Impact Crusher

Impact Crusher use impact energy to crush materials. When the impact crusher works, the motor drives the rotor rotate of the impact crusher with high speed. When the materials get into the area which the hammers effect, under the impact function of the hammer at a high speed, the materials are thrown to the impact device above the rotor continuously. And then the materials are rebounded from the impact liner to the area where the hammers effects for being recrushed, then discharged from the discharge port. Users can adjust the space between Impact Rack and Rotor Support, and then get to the expected size.

Mobile impact crusher plant

Standard Type mobile impact crusher plant is base on one certain crushing stage, with vibrating feeder, impact crusher and vibrating screen.

Working Principle

This impact crushes materials with impact force. When the materials enter the blow bar area, they are crushed due to the high-speed impact of the blow bar and are thrown to the impact plates on the rotor for secondary crush. Then the materials will be shot back to the blow bar again for the third crush. This process will repeat until the materials are crushed to the required size and discharged from the lower part of the machine.

The size and shape of the finished powder can be changed by adjusting the gap between the impact rack and rotor support. The machine employs self-weight security device in its back frame. When other objects enter the impact cavity, they will be forced out of the machine by the impact rack in the front and back of the machine.

Features and Benefits:

  • 1. Many cavity to crush, suitable for crushing hard rock.
  • 2. Low and big feed opening make the production line easy to arrange and increase the size of feeding material.
  • 3. New anti-abrasive material which prolong service life of impact hammer, impact plate and liner.
  • 4. High-chromium plate hammer, unique Impact plate, especially for hard rock crushing, high efficiency and energy saving.
  • 5. Hard stone crushing, high efficiency and energy saving.
