Ore-crushing device

Abstract

The invention discloses an ore-crushing device which comprises a coarse crusher, a double-layer sieve, an intermediate crusher, a fine crusher and a conveyor; the coarse crusher crushes raw ore coarsely; the double-layer sieve is connected with the coarse crusher and is used for receiving coarsely crushed ore from the coarse crusher and sieving the coarsely crushed ore in two stages; the intermediate crusher is connected with the double-layer sieve and is used for receiving ore on an upper-layer sieve from the double-layer sieve and intermediately crushing the ore on the upper-layer sieve; the fine crusher is connected with the double-layer sieve and is used for receiving ore on a lower-layer sieve from the double-layer sieve and finely crushing the ore on the lower-layer sieve; and the conveyor is respectively connected with the intermediate crusher and the finer crusher and is used for returning and conveying the intermediately crushed ore and the finely crushed ore to the double-layer sieve. The ore-crushing device has simple structure, less equipment and low cost.

Description

technical field [0001] The invention belongs to the technical field of ore dressing, in particular to an ore crushing device. Background technique [0002] In the traditional beneficiation process, the raw ore extracted from the mine usually goes through multiple crushing processes, and then undergoes grinding and sorting. The traditional ore crushing process is usually divided into several processes, which are carried out in different workshops. For example, the raw ore is coarsely crushed by the coarse crusher in the coarse crushing workshop, and then transported to the screening workshop for screening. When there are many grades, there are usually two processes of pre-screening and inspection screening. Different screening machines are usually used for pre-screening and inspection screening. The coarse crushed ore is pre-screened first, and the pre-screened ore is transported to the medium and fine crushing workshops for secondary crushing through the secondary crusher. ...

AI Technical Summary

Problems solved by technology

[0003] Coarse crushing equipment, screening equipment, medium and fine crushing equipment of the traditional crushing process need to be installed in different workshops, so the products of each stage need to be transported between the workshops according to the needs, which reduces the efficiency and wastes manpower and material resources

Moreover, the number of equipment is large, the floor space is large, the energy consumption is large, the investment is high, and the cost increases
