Abstract

The invention relates to a structuraly improved single-section hammer type screening crusher which belongs to mine machinery. The single-section hammer type screening crusher comprises a crusher box body, a crushing rotor, a final screening mechanism and a prescreening mechanism, wherein the crusher box body consists of a left box body, a right box body, a front box body, a back box body and an upper box body and is provided with a crushing work cavity; a feeding opening is arranged at the upper part of the left box body; the crushing rotor is positioned in the crusher box body and arranged on the front box body and the back box body; a hammer head is pivoted on the crushing rotor; the final screening mechanism is arranged in the crushing work cavity; and the prescreening mechanism is arranged at the top outside the left box body. The single-section hammer type screening crusher is characterized in that a grate body which consists of a group of grates and a grate lower connecting beam is configured on one side of the left box body, facing the crushing work cavity. The invention has the advantages of inhibiting overcrushing, ensuring that ore in the crushing work cavity is crushed and discharged at first, saving the energy consumption of the crusher and improving the crushing efficiency.

Description

technical field [0001] The invention belongs to the technical field of mining machinery, and in particular relates to a structurally improved single-stage hammer-type screening crusher for crushing limestone. Background technique [0002] As known in the industry, limestone is a mineral raw material with a wide range of uses. 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 is to say,...
