Description

Efficiency of breakage is improved hammer crusher

Technical Field

The invention relates to the technical field of mineral processing equipment, in particular to a hammer crusher capable of improving crushing efficiency.

Background

The existing hammer crusher mainly comprises a box body, a rotor arranged in the box body and a motor driving the rotor to rotate, wherein the inner wall of the box body is also provided with a counterattack crushing plate; the top of the box body is provided with a feeding pipe, and the bottom of the box body is provided with a sieve plate; be equipped with a plurality of tups on the rotor, during the use, the starter motor, the motor drives the rotor and rotates, thereby realize that the rotor drives the tup and rotates, put in the material again in to the box, it makes the material broken to rotate fast-speed impact material through the tup, partly material striking counterattack breaker under the effect of tup simultaneously, the counterattack breaker gives a reaction force of material, make material reverse movement take place to strike with the tup once more and realize the breakage, material after the breakage falls on the sieve, and sieve through the sieve, the material that the particle diameter is big is stayed on the sieve, continue to carry out the breakage through the tup.

However, the existing hammer crusher has the following technical problems in the actual use process: firstly, the crushed materials are screened by the sieve plate, the materials with larger particle sizes are left on the sieve plate, when the materials with larger particle sizes are crushed again by the hammer head, the hammer head can impact the sieve plate through the materials, so that the sieve plate is easy to damage, the powder sieving efficiency is seriously influenced, and the working efficiency of the hammer crusher is reduced; secondly, in crushing work goes on, the wearing and tearing of quartering hammer are comparatively serious, and hit efficiency not high, its leading cause is because when unloading in succession, the one side tip that the transmission shaft was kept away from to the tup collides with mineral contact for a long time, produce sliding friction, it is serious to lead to quartering hammer tip wearing and tearing, and tip wearing and tearing seriously still can increase quartering hammer and sieve, the distance between the breaker, lead to producing some great particulate matters and can't be hit the breakage once more, seriously influence crushing efficiency, and it is the highest when the material is all hit the prescription rate by the quartering hammer side, wearing and tearing are the minimum.
