A high-efficiency double-roller crusher

Abstract

The invention discloses an efficient double roll crusher. The efficient double roll crusher comprises a crusher shell, a discharging opening is formed in the outer wall of one side of the crusher shell, second sliding grooves are formed in the inner walls of two sides of the discharging opening, and a guide plate is installed on the inner wall of one side of the crusher shell. First sliding grooves are formed in the inner walls of two sides of the guide plate, discharging grooves are connected into the first sliding grooves through a first sliding block, and the first sliding block and a second sliding block are installed on the outer wall of one sides of the discharging grooves. The efficient double roll crusher is provided with a rotary seat, a crushing tooth, a driving compression roller, a driven compression roller, a hydraulic telescopic rod, the discharging grooves and a discharging baffle, the two compression rollers rotate relatively when the crusher works, materials are crushed under the extrusion of the compression rollers, the materials after crushing fall into the discharging grooves and are exhausted from the discharge opening from the discharge groove, the size of a gap between the discharging grooves and the discharging baffle determines the grinding degree of the crushed materials, and the smaller the gap, the higher the crushing degree.

Description

technical field [0001] The invention belongs to the technical field of double-roll crushers, and in particular relates to a high-efficiency double-roll crusher. Background technique [0002] Roller crusher, a kind of mining machinery, also known as double-roller crusher, is mainly used for crushing ore, suitable for industries such as coal, metallurgy, mining, chemical industry and building materials, and more suitable for large coal mines or raw coal in coal preparation plants (including gangue) crushing. [0003] However, the existing pair of roller crushers rely on the extrusion force of the rollers to crush the ore during work, the crushing quality is low, and it is not convenient to control the degree of crushing during the working process of the crusher. In addition, the existing crushers all have pressure roller gaps Adjusting device and safety spring buffer device, but the buffering effect of the safety spring buffer device is likely to be affected during the proces...
