When expanding the production of building materials, the demand for crushing equipment is increased. In many cases, the construction of a new dwelling entails the demolition of old buildings. Building garbage piles are formed, which, after processing on crushing installations, become good secondary raw materials. Significant advantages have spare parts for crushers. They can be used complete with movable devices, because they are easy to install and dismantle. According to the design, the crushers are divided into cheek, hammer, conical crushers and rotary crushers with a steep and flat wheel position. The crushers crushes strong or soft rocks, the remains of industrial output, builder, plastics and household waste. Depending on the type of crusher, crushing can be carried out by sawing, clash and crushing.
