Problems solved by technology

At present, the known solution is to replace the tup on the crushing rotor. Although the replacement of the tup can make up for the above defects, there are undoubtedly the following problems: one is because the replacement of the new tup needs to be carried out in a shutdown state, and due to the The replacement time is long, which affects the continuity of production; second, because the hammer head itself is very heavy, it requires the cooperation of many people to replace it, and the labor intensity of the workers is high; third, because the replacement hammer head can only be discarded, it causes waste of resources , and increase the equipment use cost of the unit using the crusher, which is contrary to the economical and energy-saving spirit advocated by the whole society

Abstract

The invention discloses an adjustable single-section hammer screening crusher for a final screening mechanism, which belongs to mining machinery. The crusher comprises a crusher box body, a crushing rotor, the final screening mechanism, a pre-screening mechanism and a grid body, wherein the crusher box body consists of left, right, front and back boxes and an upper box and is provided with a crushing working cavity; the upper part of the left box serves as a feed inlet; the crushing rotor is provided with a hammer head and positioned in the crusher box body; the final screening mechanism is arranged in the crushing working cavity; the pre-screening mechanism is arranged on the top of the outer side of the left box; and the grid body is arranged on the left box and faces the final screening mechanism. The crusher is characterized in that: a first horizontal cushion block support edge is arranged at the bottom of the outer wall of the left box; a second horizontal cushion block support edge is arranged at the bottom of the outer wall of the right box; and the final screening mechanism comprises a first screening grate, a second screening grate, a pair of first screening grate support frames, a pair of second screening grate support frames and a support roller. The crusher has the advantages of lowering working intensity, saving resources, lowering use cost, along with short downtime and convenient and rapid adjustment.

Description

technical field [0001] The invention belongs to the technical field of mining machinery, and in particular relates to a single-stage hammer-type sieving crusher with an adjustable final sieving mechanism, which is used for crushing limestone. Background technique [0002] As we all know, limestone is a widely used mineral raw material. In addition to being used to make cement, it is often used as a flux in metal smelting. Limestone is also an important material in power plant desulfurization and calcium carbide production. Active lime is mostly used in power plant desulfurization and calcium carbide production, and active lime is calcined from granular limestone. At present, when the shaft kiln method is used for calcination, the particle size of the limestone is required to be about 40-120mm; when the rotary kiln is used for calcination, the particle size of the limestone is required to be about 10-50mm. Limestone smaller than the above particle size cannot be used. That ...
