Abstract

The invention discloses building waste refining equipment which comprises a cylindrical shell. The shell is transversely arranged; a cylindrical grinding body is arranged in the shell; the inner wall of the shell and the outer wall of the grinding body are each provided with a grinding face, and the grinding faces are composed of reticulate knurls; the grinding body and the shell are eccentrically arranged, the axis of the grinding body is lower than the axis of the shell, and the axis of the grinding body is parallel to the axis of the shell; a grinding gap is formed between the grinding body and the shell, and the width of the grinding gap is gradually reduced from top to bottom; and the two ends of the shell are connected with end covers through flanges. According to the building waste refining equipment, the grinding gap which is gradually reduced downwards can be formed through the eccentrically-arranged grinding body, materials are gradually refined along with rotation of the grinding body and start to sink under the action of gravity to be further refined, and the refined materials are outwards discharged through a discharging opening in the lower portion of the shell.

Description

technical field [0001] The invention relates to a construction waste refining equipment. Background technique [0002] After dismantling the waste buildings, the buildings need to be recycled and reused. There are two recycling schemes in the prior art, the first is to recycle bricks, and the second is to recycle steel bars. When recycling bricks, it is necessary to remove the concrete and other materials attached to the surface of the bricks. When recycling steel bars, it is necessary to remove the concrete attached to the surface of the steel bars. [0003] Both of the above two recycling schemes will produce a large amount of materials after the recycling is completed, and the materials include concrete fragments, paint powder and so on. In the prior art, these materials are usually used as excavation materials, and the use method is single, and the utilization rate is not high. Especially in high-rise construction operations, such recycled concrete fragments are not s...
