Ore grinding process

Abstract

The invention discloses an ore grinding process. The ore grinding process comprises the following steps: performing coarse crushing on a raw ore by using a crushing machine; performing two-grade sorting on a coarsely-crushed ore by using a vibration sorting machine to obtain a large crushed ore and a small crushed ore; returning the large crushed ore to the crushing machine, enabling the small crushed ore to enter acid liquid for soaking and air-drying, and enabling the small crushed ore into a grinding machine; collecting a dust-level ore by using an air engine which is connected with the grinding machine; and screening large granular crushed minerals by using a screening machine which is connected with the grinding machine, returning a coarse powder ore into the grinding machine for grinding again, collecting a fine powder ore, and performing acid pickling and airing on the collected fine powder ore for later use. By adopting the ore grinding process, the content of impurities in the collected fine powder ore can be reduced to a highest extent, the purity degree of the minerals can be ensured, the qualification degree of raw materials in a machining process can be ensured, and the use effect of products can be ensured.

Description

technical field [0001] The invention belongs to the technical field of mineral processing, in particular to an ore crushing process. technical background [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 cr...

Problems solved by technology

Concentrated crushing of minerals, multi-stage crushing steps, so that minerals can achieve better crushing effect, according to different requirements to obtain mineral raw materials of different specifications, in order to achieve more crushing and less grinding, reduce energy consumption, improve efficiency, and other The process of processing ore is all physical treatment. The impurities in the ore cannot be effectively removed together. The high content of impurities in the collected raw materials will affect the use effect of the raw materials. The raw materials are processed after sale, and the weight loss of raw materials is relatively large. Large, affecting the commercial value of raw materials
