Ore muck separation system

Abstract

The invention discloses an ore muck separation system which comprises a material tank and a grizzly feeder. A crushing machine is arranged at the position of a material outlet of the grizzly feeder, a sieving device is arranged at the position of a hopper below a grizzly sieving face of the grizzly feeder, a belt conveyor I is arranged at the position of a material outlet of the sieving device, an aggregate storage bin is arranged at a discharging end of the belt conveyor I, a belt conveyor II is arranged at the position of an outlet below the sieving face of the sieving device, and a muck bin is arranged at a discharging end of the belt conveyor II. Compared with ore muck separation systems, the ore muck separation system has the advantages that stripping aggregated rock generated during ore extraction is comprehensively treated by means of a winnowing process, and selected muck contains siliceous corrective additions required for firing clinker, so that the selected muck can be used as a raw material for producing Portland cement clinker, the purpose of comprehensive utilization of resources is achieved, problems that the muck in ores pollutes environment, occupies land and wastes resources are solved, and comprehensive utilization of the ore resources is achieved.

Description

technical field [0001] The invention relates to the field of concrete aggregate production, and belongs to the industries of cement, concrete aggregate and artificial sand production. Background technique [0002] With the needs of urban development, many cities restrict on-site mixing of concrete and dry powder mortar, commercial concrete mixing plants are built on a large scale, and the urbanization process is accelerated, which increases the demand for sand and gravel for construction, and natural river sand and pebbles have been consumed In this case, artificial production of commercial concrete aggregate and artificial sand is imminent. Due to the strict requirements of commercial concrete on aggregate and machine-made sand, the content of muck, miscellaneous soil and stone powder in aggregate has a certain upper limit. Therefore, the soil and excess stone powder should be sorted out. At present, artificial production of commercial concrete aggregates and sand selectio...

Problems solved by technology

[0005] Beneficial effects: Compared with the prior art, the present invention adopts the wind separation process to comprehensively process the stripped stones produced in ore mining, and the sorted dregs (because the dregs contain silicon correction required for firing clinker) material) can be used as raw materials for the production of Portland cement clinker, to achieve the purpose of comprehensive utilization of resources, and to solve the problems of environmental pollution and land occupation of dregs in ores, and to realize the comprehensive utilization of mine resources
