Barmac® crushers accept fines in the feed and allow user to finetune crusher's performance by changing the rotor speed or cascade ratio. The primary path for feed material is through the rotor where it can be accelerated up to 80 m/s (262 ft/s) before being discharged into the crushing chamber.
Feed to the crusher must be well prepared as far as top size and must be free of tramp iron. Because of the brittle nature of this alloy, tramp iron will cause catastrophic failure of the blow bars. This material is used in secondary, tertiary and asphalt recycle applications where there is no tramp iron.

Cone Crushers. A Cone Crusher is a compression type of machine that reduces material by squeezing or compressing the feed material between a moving piece of steel and a stationary piece of steel. Final sizing and reduction is determined by the closed side setting or the gap between the two crushing members at the lowest point.
Jun 02, 2017· Industrial crushers reduce large rocks, ore or waste materials to smaller sizes by impact or pressure to fracture or deform the material. During the primary crushing operation, boulder size feeds from 20 to 100 in. are reduced to secondary crusher sizes of 1 to 20 in. or mill feed size of .5 to 3 in.
The gape determines the maximum size of material that can be accepted. Maximum size that can be accepted into the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4:1 and 9:1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3:1 to 10:1.
achieve the desired size reduction. Gyratory crushers, jaw crushers, roll crushers, and impact mills are used for primary and secondary crushing. After crushing, the size of the material is further reduced to 50 micrometers ( m) or smaller by grinding, using smooth rolls, …
The feed material is entering the machine through the vertical fall into the impact circle of the rapidly rotating hammer heads. A high crushing performance is achieved by the first impact. In the next step, the pre-crushed granulate is thrown against the upper baffle plate where it is crushed once more.
Jun 10, 2020· For horizontal shaft impact crushers, blow bars are inserted into the rotor and at high speeds, the rotor spins repeatedly striking the material.This process fractures the material until it meets the appropriate size to fall through the impact crusher chamber. Due to this process, the type of blow bars selected and how they are managed, and just importantly maintained, will influence the ...
The process is repeated until the stone reaches the desired size. Impact crushers are ideal for mixed materials. They can crush clay, dirt or metal mixed with the feed material, for example reinforcing bars, wire mesh or anchors. They can crush hard materials, but …
