Description

Impact crusher

Technical Field

The invention relates to the technical field of mining machinery, in particular to a reaction crusher.

Background

The stone of adopting when the mining is not of uniform size, and a very big part stone can not the direct use, thereby need carry out crushing treatment to big stone and obtain littleer stone, wherein the counterattack formula breaker is exactly a crushing machine commonly used, its principle utilizes the impact energy to break, with the stone to the inside input of organism, drive the rotor through the motor and rotate, thereby stone and the board hammer collision on the rotor are broken and at the rotor outside set up the counterattack frame, the cooperation carries out collision processing many times to the stone, this kind of breaker is because of the treatment range wide, the compressive capacity is strong and the breakage ratio is big and receive the wide use, but it still has certain problem:

the stones falling into the rack from the inlet can directly hit the plate hammer when falling into the rotor frame and then rebound to the outlet, so that certain danger is realized, the operation of workers nearby is not facilitated, and meanwhile, the falling speed of the entering stones is influenced differently due to different sizes and shapes, so that the crushing effect is greatly different, and the quality of the stones is influenced;

when striking broken stone, because the interval influence between the adjacent board hammer can lead to the stone to fall and can be in different positions on the rotor frame, also can receive different power when rotating to throw away like this, and then lead to the crushing effect gap great, probably lead to big stone breakage to reach the requirement even, only utilize the rotor to rotate the power of throwing away the stone and carrying out the counterattack collision and can not reach the effect of ideal sometimes when carrying out the breakage of big stone simultaneously, can not guarantee that broken stone all meets the requirements.
