Strike back type crusher
It is the high speed that uses bar pound and strike back board spring back action, make stock is relapsed pound and broken machine. Bar solid installs the rotor that rotates in high speed, decorate by different point of view along broken antrum a certain number of piece strike back board.

The effect zone time that stock enters bar is pounded first by the first time of bar and broken the first time, achieve kinetic energy at the same time, high speed bears down on strike back board. Stock and strike back board collision again broken hind, be played to return the action area of bar, get afresh the concussion of bar. Undertake repeatedly so, until by broken outside into wants size eduction machine.

Compare with hammer type crusher, strike back of type crusher broken than bigger, use the high speed blow energy of whole rotor adequately. But wear away extremely easily as a result of bar, it also is restricted on the application with hard broken stock, use normally thick broken, medium broken or finely limestone, coal, calcium carbide, quartz, dolomite, pyritic stone, gesso and industrial chemicals in hard the following brittleness stock.
