Abstract

The invention provides a crushing and screening device. The crushing and screening device comprises a crushing part and two screening parts. A pair of rollers is arranged in a crushing cavity. Fixing plates are arranged on the inner walls of the two sides of the crushing cavity. Bristles are arranged on the fixing plates. Each screening part comprises a sleeve and an S-shaped screening cylinder which is arranged in the sleeve. The lower end of each S-shaped screening cylinder is connected with a rotating motor. Each S-shaped screening cylinder communicates with the corresponding sleeve through a plurality of screening holes which are formed in the side wall of the S-shaped screening cylinder. A plurality of barrier strips are arranged on the two sides of the inner wall of each sleeve in a vertically-staggered mode. According to the crushing and screening device, the S-shaped screening cylinders are matched with the rotating motors, so that centrifugal force is increased, and screening efficiency is effectively improved; in addition, the crushing and screening device has excellent self-cleaning performance, the bristles can remove materials adhering to the pair of rollers during work, the barrier strips can continuously flip the S-shaped screening cylinders along with rotation of the rotating motors, and the screening holes are effectively prevented from being blocked; and furthermore, air compressors are arranged, so that the cleaning effect is good, and the problem that a screening device is difficult to clean is effectively solved.

Description

technical field [0001] The invention relates to the technical field of mechanical crushing and screening, in particular to a crushing and screening device. Background technique [0002] my country has used fly ash to produce sintered solid bricks for half a century. After the fly ash and shale, kaolin, refractory clay and other binders are transported to the raw material yard, they are first mixed according to the blending ratio. Sieve and sieve, crush and process the sieve residue, and then sieve with an 88-micron aperture sieve to ensure that the particle size is less than 0.005mm, then crush the second sieve residue, and sieve to remove slag. At present, in the crushing and screening process, because the moisture content of the raw materials cannot be effectively controlled, the crusher and the trommel screen will be frequently blocked, which will take a lot of time and manual cleaning, resulting in low production efficiency and greater damage to the equipment, which incre...
