Cooling type high-efficiency dry sorting machine

Abstract

The invention discloses a cooling type high-efficiency extracted product dry magnetic separator which comprises a speed reducer connected with a motor and a main shaft magnetic drum, wherein the main shaft magnetic drum consists of a hollow main shaft, a magnetic block, an aluminum disk and an outer barrel; the speed reducer is connected with the aluminum disk through a coupling; the aluminum disk is connected with the outer barrel; a reversible multi-sheet material returning plate is arranged at the outer side of the outer barrel; and a protection cover is arranged on the outer side of the reversible multi-sheet material returning plate. By the cooling type high-efficiency dry magnetic separator, the rotating speed of a main shaft is greatly improved and can be converted from 40 r / m to 40-180 r / m; the rotating speed can be selected according to the property of ores, and the level of the selected metal iron ore is high; the comprehensive working rate of equipment is greatly improved; and the tonnage consumption cost of equipment is greatly reduced when the equipment runs.

Description

technical field [0001] The invention relates to a kind of ore dressing mechanical equipment, in particular to a cooling-type high-efficiency product-extracting dry separator. Background technique [0002] The transfer speed of the existing dry separator is slow, and the grade of the selected metal iron ore is not high, especially if there are too many non-magnetic inclusions. If the material is wet, due to the inclusion of magnetic and non-magnetic ores, the grade of the selected ore is low. As a result, the output of existing equipment is low and the cost per ton is high. [0003] The magnetic barrel of the main shaft of the existing dry separator is connected by a solid half shaft, and the reducer adopts a standard solid shaft, so the speed cannot be increased, and the temperature inside the barrel cannot dissipate heat. Contents of the invention [0004] Aiming at the deficiencies in the above-mentioned prior art, the present invention provides a cooling-type high-effi...

Problems solved by technology

[0002] The transfer speed of the existing dry separator is slow, and the grade of the selected metal iron ore is not high, especially if there are too many non-magnetic inclusions. If the material is wet, the grade of the selected ore is low due to the inclusion of magnetic and non-magnetic ores. Leading to low output and high cost per ton consumption of existing equipment

[0003] The magnetic barrel of the main shaft of the existing dry separator is connected by a solid half shaft, and the reducer adopts a standard solid shaft, so the speed cannot be increased, and the temperature inside the barrel cannot dissipate heat.
