Compression crushers which squeeze the material until it breaks. Impact crushers which use the principle of rapid impact to shatter material. A ttrition crushers which use both impact and grinding to shear material. Jaw crushers, cone crushers, gyratory crushers and roll crushers all operate on the compression principle.

The first step to recycling old concrete is to use industrial crushing equipment in order to break up the original structure. Next, the broken up concrete is run through a secondary impactor. After being crushed to an even smaller size, the crushed concrete is then screened so that dirt and other foreign objects can be removed.

General Information/Equipment Design. Size reduction in impact crushers occurs through particle concussion by rigid forces. The hammer crusher, also called the hammer mill, is an example of an impact crusher. In hammer crushers, hammers swing freely on a disc mounted on the main shaft within the device.
