Description
Technical Field
The utility model relates to the technical field of crushers, in particular to a pre-crushing device of a reaction crusher.
Background
Impact crushers are crushing machines that utilize impact energy to crush material. When in work, the motor drives the rotor to rotate at high speed, when the materials enter the action area of the plate hammer, the materials are impacted by the high speed of the plate hammer to be crushed, the crushed materials are thrown to the impact plate arranged above the rotor along the tangential direction to be crushed again, then the impact plate rebounds to the action area of the hammer to be crushed again, the process is repeated until the materials are crushed to the required granularity and discharged from the discharge hole, and the purpose of changing the granularity and the shape of the materials can be achieved by adjusting the gap between the impact frame and the rotor.
But when broken material volume is very big, can't carry out the preliminary treatment to the material, and the massive material can cause very big wearing and tearing to hammer and counterattack board, has reduced the life-span of counterattack board and hammer, needs frequent change hammer and counterattack board, has reduced the production efficiency of breaker when having increased use cost.
To this end, we propose a reaction crusher pre-crushing device that solves the above mentioned problems.
