Abstract

The invention discloses a single-section hammer type screening crusher, belonging to mining machinery and comprising a crusher box body, a crushing rotor and a final screening mechanism, wherein the crusher box body comprises a left box body, a right box body, a front box body, a rear box body and an upper box body and is provided with a crushing work cavity; a feed opening is arranged at the upper part of the left box body; the crushing rotor is positioned in the crusher box body, is arranged on the front box body and the rear box body and is provided with a hammer head; and the final screening mechanism is arranged in the crushing work cavity. The single-section hammer type screening crusher is characterized in that a pre-screening mechanism is arranged at the position of the outer sideof the left box body, which corresponds to the feeding opening; a grill body is arranged on the left box body, orients towards one side of the crushing work cavity and corresponds to the upside of the feeding opening; and the pre-screening mechanism, the grilling body and the final screening mechanism sequentially form the gradient relationship of gradually reducing from top to bottom in the height. The single-section hammer type screening crusher has the advantages of inhibiting the over crushing, ensuring that coarse materials in the crushing work cavity are first crushed and first output, saving the energy source 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 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 also commonly 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, the calcinati...
