Upwards impact type single-section hammer type crusher

Abstract

An upwards impact type single-section hammer type crusher comprises a feeding part and a crushing part, wherein a discharging scraper-trough conveyer is arranged between the feeding part and the crushing part; an upper cover is installed in a shell in the crushing part and provided with a chaining screen door; the upper portion of the upper cover is provided with a balancing weight; an impact plate is installed on the lower portion of the upper cover; the feeding angle of the crushing part ranges from 135 degrees to 145 degrees. The upwards impact type single-section hammer type crusher changes the feeding angle of materials by eliminating a material supporting board on the discharging scraper-trough conveyer, and the beneficial effect of improving the work efficiency of the single-section hammer type crusher is achieved; the impact plate is installed on the lower portion of the upper cover, and the balancing weight is installed on the upper portion of the upper cover, so that the original access door function is reserved, the upper cover has the crushing function, impact of the materials to the upper cover is relieved, and the beneficial effect of reducing abrasion to spare parts is achieved.

Description

technical field [0001] The invention relates to a crushing machine, in particular to an upward-hitting single-stage hammer crusher. Background technique [0002] The single-stage hammer crusher is widely used for crushing brittle materials such as limestone, gypsum, coal, marl, sand shale, etc. In the existing single-stage hammer crusher, the material falls to the discharge chute after passing through the curtain. The set material pallet holds up the rolled material, and throws it into the middle section of the hammer head bracket under the action of inertia, and the feeding angle is within 135°. Under the impact of the high-speed running hammer head, a part of it rushes to the impact plate , the other part rushes to the upper cover, and the counter-attack plate gives a counter-attack to the beaten material under the support of the shell, and the material block will be broken into small pieces and powdery materials, which fall on the discharge grate below, and the upper cove...
