Dry-type automatic sorting system for crude talc ore

Abstract

The invention relates to a dry-type automatic sorting system for a crude talc ore. The system is characterized in that a material-feeding hopper is sequentially and technically connected with a regulating gate, a reciprocating vehicle, a hoisting machine and a dry-type arc-shaped elasticity sorting machine; the dry-type arc-shaped elasticity sorting machine is provided with a dust extracting pipeand connected with a dust remover and a draught fan; three outlets are arranged below the dry-type arc-shaped elasticity sorting machine; the outlet I, the outlet II and the outlet III are correspondingly connected with a fine-grain raw material warehouse, a medium-grain raw material warehouse and a coarse-grain raw material warehouse respectively through a fine-grain conveyer, a medium-grain conveyer and a coarse-grain conveyer; and the dry-type arc-shaped elasticity sorting machine comprises an enclosed shell, a supporting seat, an elastic rubber block and an arc-shaped bottom board. Compared with the prior art, the system provided by the invention has the following beneficial effects that: 1, the system can be directly used for the crude talc ore dry sorting and in particular to the sorting of the talc below 25 mm, and the sorting rate over 95 percent is achieved; 2, the sorting process is completely closed so that no water and dust pollution are generated; and 3, a phenomenon of blocking a filter screen does not appear because an elastic nylon filter screen is used.

Description

technical field [0001] The invention relates to the field of talc raw ore separation, in particular to a dry type automatic separation system for talc raw ore. Background technique [0002] At present, the sorting of domestic talc raw ore mainly relies on the following two methods. One is to use manual selection of raw ore. The disadvantages are: it increases the labor intensity of workers, the work efficiency is too low, the production cost is too high, and the size of the raw ore is too small. Particle selection is difficult; the second is to sort the powder by flotation. The area is large, the pollution caused by sewage and tailings is relatively serious, the discharge is not easy to deal with, the utilization rate of mineral resources is low, and water resources are wasted. Contents of the invention [0003] The purpose of the present invention is to provide a dry-type automatic sorting system for talc raw ore, which overcomes the deficiencies of the prior art, has si...
