A Ring Hammer Crusher with Rigid Screen

Abstract

The invention relates to the technical field of crushing equipment, and discloses a ring hammer crusher with a rigid filter screen. Through the arrangement of partial gears, all-tooth gears, pull ropes and pull rods, during the crushing work, the motor works to drive the first shaft to rotate, and while the particles are broken, the belt drives part of the gears to rotate. When meshing, the winch rewinds the pull rope, so that the pull rod overcomes the elastic force of the second spring to drive the bracket to move down and accumulate force. When the full-tooth gear continues to rotate to the point where it does not mesh with part of the gear, the second spring is under the action of its own elasticity. Quick rebound, rewind the winch, and at the same time make the filter screen go up quickly, throw up the coarse particles accumulated on the surface of the filter screen and get close to the ring hammer, repeating the cycle, which is convenient for the secondary or even multiple crushing of the coarse particles, and improves the crushing performance. efficiency.

Description

technical field [0001] The invention relates to the technical field of crushing equipment, in particular to a ring hammer crusher with a rigid filter screen. Background technique [0002] The ring hammer crusher crushes the material by the collision of the high-speed rotating hammer body and the material. It has the characteristics of simple structure, large crushing ratio and high production efficiency. It can be used for dry and wet crushing. The ring hammer crusher is suitable for mining, Cement, coal, metallurgy, building materials, roads, combustion and other departments finely crush medium-hard and brittle materials. The main working part of the ring hammer crusher is a rotor with a hammer (also known as a hammer head). It consists of a disc and a hammer. The motor drives the rotor to rotate at a high speed in the crushing chamber. The material is fed into the machine from the upper feeding port, and is crushed by the impact, impact, shearing and grinding of the high-s...

AI Technical Summary

Problems solved by technology

[0003] However, the existing ring hammer crusher still has the following deficiencies in the actual use process. Since the sieve plate is fixed at the lower part of the rotor, and the gap between the sieve plate and the rotor is small, it is convenient to continue to be hit and ground by the hammer. After the large-sized incompletely broken coarse grains fall onto the sieve plate, the coarse grains are easily stuck in the gap between the sieve plate and the hammer. Severe wear and tear will cause damage to the sieve plate, and even cause coarse particles to jam the crusher, causing damage to the motor; and when the sieve plate is set lower, the unbroken coarse particles will not be able to continue to be hit by the hammer and grinding, not only cannot be crushed, reducing the crushing efficiency, but also with the accumulation of coarse particles, it is easy to cause blockage of the sieve plate and affect the discharge effect
