Grading and dust removal system used for mineral pretreatment

Abstract

The invention discloses a grading and dust removal system used for mineral pretreatment. The system comprises a support, the upper side of the support is fixedly connected with a box body, a protection cover is fixedly connected to the outer side wall of the box body, a material accumulation hopper is fixedly connected to the upper side of the box body, the lower side of the material accumulationhopper is rotatably connected with a moving column, two breaking wheels are rotatably connected into the box body, a base plate is arranged in the box body, a turbine is rotatably connected to the base plate, a screening plate is arranged between the turbine and the base plate, one side of the box body is connected with an upper cover through a hoop strip, and the lower side of the upper cover ismovably connected with a collection barrel. Through a fan, mineral dust doped inside is blown into the upper cover through a channel, through mist sprayed out of a nozzle of an atomizing pump, mineraldust is rapidly attached on water beads in the air and falls and is recycled into the collection barrel, environment pollution and the hurt to bodies of persons can be reduced, and resource waste canbe avoided.

Description

technical field [0001] The invention relates to the technical field of mineral classification and dust removal, in particular to a classification and dust removal system for mineral pretreatment. Background technique [0002] Solid minerals require different particle sizes according to different uses, so minerals need to be graded and crushed after smelting. At present, most minerals are crushed by conventional mechanical crushing. The investment in mechanical crushing equipment is small and the safety factor is high. However, conventional The mechanical crushing method leads to uneven mineral particles after crushing, so screening equipment is required for screening, which increases the investment in equipment; mineral dust will be generated during screening and crushing of minerals, and these dusts have high industrial utilization value Yes, but most of the existing screening and crushing equipment does not have a dust collection device. When the minerals are crushed and s...

[0002] Solid minerals require different particle sizes according to different uses, so minerals need to be graded and crushed after smelting. At present, most minerals are crushed by conventional mechanical crushing. The investment in mechanical crushing equipment is small and the safety factor is high. However, conventional The mechanical crushing method leads to uneven mineral particles after crushing, so screening equipment is required for screening, which increases the investment in equipment; mineral dust will be generated during screening and crushing of minerals, and these dusts have high industrial utilization value Yes, but most of the existing screening and crushing equipment does not have a dust collection device. When the minerals are crushed and screened, the dust is flying, which not only pollutes the environment and affects the health of employees, but also causes a waste of resources. Therefore, we propose a Classification and dedusting systems for mineral pretreatment
