Sand and stone production system

Abstract

The invention discloses a sand and stone production system. The sand and stone production system comprises a sand and stone dust remover, a feeder, a screening machine and a sand and stone sorting machine. A discharging opening is formed in the feeder. A discharging opening is formed in the screening machine. A feeding opening is formed in the sand and stone dust remover. A stirring mechanism fordriving dust diffusion is arranged in the sand and stone dust remover, and the stirring mechanism comprises a stirring cylinder, a rotating shaft arranged in the stirring cylinder and a plurality of rotating plates. Due to the adoption of the mechanisms, the sand and stone can be prepared in different specifications, the application range is wider, the practicability is improved, and the sand production efficiency is increased; and the stirring mechanism stirs sand and stone through a rotating plate and the rotating shaft, and a stirring drum is used for accommodating sand and stone, so that dust can diffuse out of the stirring drum by rotating the rotating plate to drive the dust to float up, the dust removal effect is achieved, the dust removal efficiency is greatly improved, and the environment pollution due to the fact that the dust spreads into the air is effectively prevented.

Description

Technical field [0001] The invention belongs to the technical field of machinery, and particularly relates to a sand and gravel production system. Background technique [0002] At present, the sand making system on the market generally uses a vertical shaft impact crusher as the crushing equipment. The vertical shaft impact crusher crushes more coarse stones and less fine stones. The gradation is unreasonable and difficult to adjust. In addition to the difficulty of adjusting the fineness modulus of the stone and the high content of stone powder, a lot of fine powder will be produced during the sand making process. The fine powder produced by the existing sand making system during the crushed sand manufacturing process is generally not dusted. Treatment, which makes the sand making environment extremely deteriorated. In order to prevent the fine powder from scattering, some enterprises seal the conveyor mechanism such as a belt conveyor in the screening machine and the sand and ...
