Description

Ring hammer crusher with rigid filter screen

Technical Field

The invention relates to the technical field of crushing equipment, in particular to a ring hammer crusher with a rigid filter screen.

Background

The ring hammer crusher crushes materials by collision between a hammer body rotating at high speed and the materials, has the characteristics of simple structure, large crushing ratio, high production efficiency and the like, can crush materials in a dry mode and a wet mode, is suitable for departments such as mines, cement, coal, metallurgy, building materials, highways, combustion and the like to crush medium-hardness and brittle materials, has a rotor with a hammer (also called a hammer head) as a main working part, consists of a main shaft, a disc and the hammer, drives the rotor to rotate at high speed in a crushing cavity by a motor, feeds the materials into the machine from an upper feeding port, crushes the materials by the striking, shearing and grinding effects of the hammer moving at high speed, is provided with a sieve plate at the lower part of the rotor, discharges the grain fraction smaller than the size of a sieve mesh in the crushed materials through the sieve plate, and blocks the hammer and the grinding which are continuously suffered by the striking of the sieve plate larger than the size of the sieve mesh, finally, the waste water is discharged out of the machine through a sieve plate.

However, the existing ring hammer crusher has the following defects in the actual use process, because the sieve plate is fixed at the lower part of the rotor, and the gap between the sieve plate and the rotor is small, the sieve plate is convenient to continue to be struck and ground by the hammer, so that after large-size incompletely crushed coarse particles fall on the sieve plate, the coarse particles are extremely easy to be clamped in the gap between the sieve plate and the hammer, when the hammer head moves at the speed of a pole block, the sieve plate and the hammer head are seriously abraded if the hammer head moves at a low speed, the sieve plate is damaged if the hammer head moves at a high speed, and even the crusher is clamped by the coarse particles, so that the motor is damaged; and when setting up the sieve in the below, the coarse grain that is not broken will not continue to receive the strike and the grinding of hammer, not only can't be broken, reduces crushing efficiency, can easily cause the sieve to block up along with the accumulation of coarse grain moreover, influences ejection of compact effect.
