Description
Technical Field
The utility model relates to a magnesite ore dressing technical field specifically is a sorting system of magnesite and talcum.
Background
Magnesite is an important strategic mineral resource, is an indispensable refractory material in metallurgy, chemical industry and nonmetal industry, and can be used for preparing high-end functional materials required in the fields of aerospace, aviation, military, metallurgy, environmental protection and the like. Because the magnesite resource reserves are relatively rich and concentrated, the ore grade is higher and the impurities are less, the magnesite development for many years has serious phenomena of 'mining, enriching and abandoning poor', and depends on high-grade ore (the MgO content is more than 46%) which can be directly utilized without enrichment for a long time. However, with the depletion of high-grade magnesite resources and the increasing demand of downstream industrial chains for magnesite ore raw materials, the efficient and high-value development and utilization of magnesite resources (with MgO content less than 45%) which have been stripped and accumulated as waste rock in the past becomes a problem to be solved urgently.
The magnesite ore mainly comprises magnesite, brucite, periclase and the like, and the gangue mineral is dolomite, talc, iron magnesite, sericite, chlorite, sepiolite, tremolite, quartz, limonite and the like. Talc is often associated with magnesite, the talc needs to be separated out in the magnesite purification process, the current domestic common method is a flotation method, although the flotation process can effectively separate the talc, a large amount of medicament and a large amount of water are often used, the cost is high, and environmental pollution can be caused.
Disclosure of Invention
An object of the utility model is to provide a sorting system of magnesite and talcum to solve above-mentioned background technical problem.
The technical scheme of the utility model is realized like this:
the utility model provides a sorting system of magnesite and talcum, includes hammer crusher, shaft furnace, to roller crusher, double-deck shale shaker, electric separator and strong magnetic separator, hammer crusher's ore discharge mouth passes through the cloth machine with the ore inlet of shaft furnace and is connected, the ore discharge mouth of shaft furnace passes through band conveyer with the ore inlet to roller crusher and is connected, the ore discharge mouth to roller crusher passes through screw conveyer with the ore inlet of double-deck shale shaker and is connected, the ore discharge mouth on the sieve of double-deck shale shaker passes through screw conveyer with the ore inlet of electric separator and is connected, the middle level ore discharge mouth of double-deck shale shaker passes through screw conveyer with the ore inlet of strong magnetic separator and is connected.
Further, the shaft furnace is provided with a cooling device.
Further, the strong magnetic separator is a dry strong magnetic separator.
The utility model has the advantages that:
the utility model discloses a breakage in advance-calcine-grading selection process, calcine through the shaft furnace and reduce the magnesite hardness, improve the talc hardness, then through crushing to the roller crusher, fragile magnesite is broken in advance, the broken difficulty of talc, the magnesite and talc separation are realized to rethread grading, then further improve the magnesite grade by electric separator and strong magnetic separator, whole process dry-type selection is other, has practiced thrift a large amount of water consumption, and simple process, and is with low costs, has better social and economic benefits.
