Abstract
The permanent magnetic drum magnetic separator is characterized in that a roller type ore discharging device consisting of an ore discharging roller, a bearing mechanism and a transmission mechanism is arranged on an ore discharging port of a separation groove body, and has the advantages of clean ore discharging, ore discharging flushing water saving, high concentration of magnetic separation tailings, simple flow and less investment. The loss of useful fine-grained minerals is avoided.
Description
The utility model relates to permanent-magnet drum type magnetic separator, is applicable to industrial mineral and the higher place of technological requirement magnetic tailing concentration that strongly magnetic mineral content is low.
Common permanent-magnet drum type magnetic separator sorts liking magnetic iron ore, strongly magnetic mineral is adsorbed in the separation tube surface during sorting under magneticaction, when the mineral that sub-elect rotate to the gape place with the sorting cylindrical shell, magneticaction reduces, and strongly magnetic mineral breaks away from the separation tube surface and discharges as concentrate under the effect of flushing water.Because strongly magnetic mineral content is big in the magnetic iron ore, strongly magnetic mineral is continuously poured into gape, is squeezed in narrow gradually ore discharge channel, its water content is reduced form the magnetic envelope, has limited magnetic tailing concentration and has reduced significantly.Under general situation, strongly magnetic mineral content is 35～50% the time in giving the ore deposit, if feed ore concentration is 30～40%, its magnetic tailing concentration is between 12～18%.When strongly magnetic mineral content is low, be difficult for forming the strongly magnetic mineral layer, under the effect of flushing water, the strongly magnetic mineral part landing that is adsorbed in the separation tube surface is accumulated in the sorting cell body, influences the ore dressing effect.
The purpose of this utility model is in order to overcome above-mentioned deficiency, and proposing a kind of row, to unload mineral clean, saves and unload the ore deposit flushing water, and magnetic tailing concentration height directly enters down subjob, saves concentrated operation, the magnetic separator of small investment.
Permanent-magnet drum type magnetic separator, comprise frame, transmission system, sorting cell body, sorting cylindrical shell, permanent-magnet, concentrate hopper, give the ore deposit case, it is characterized in that on sorting cell body gape, being provided with by what be bearing in that surface that centre-height on the Bearning mechanism is lower than sorting cylindrical shell centre-height 80～100mm has a netted groove and unload the ore deposit roller, be packed in the frame upper support and unload the Bearning mechanism of ore deposit roller, and unload the roll-type that transmission mechanism that the ore deposit roll shaft is connected forms and unload the ore deposit device.
Owing to adopted technique scheme, the utility model compared with the prior art, having row, to unload mineral clean, save and unload the ore deposit flushing water, magnetic tailing concentration height, flow process is simple, the advantage of small investment has been avoided the loss of useful fine mineral.

Below in conjunction with the embodiment shown in the description of drawings the utility model is further described.
Permanent-magnet drum type magnetic separator, comprise frame (5), transmission system, sorting cell body (6), sorting cylindrical shell (2), permanent-magnet (8), concentrate hopper (4), give ore deposit case (1), it is characterized in that unloading ore deposit roller (9) being provided with on the sorting cell body gape by what be bearing in that surface that centre-height on the Bearning mechanism (10) is lower than sorting cylindrical shell centre-height 80～100mm has a netted groove, be packed in the frame upper support and unload the Bearning mechanism of ore deposit roller, and unload the roll-type that transmission mechanism (11) that the ore deposit roll shaft is connected forms and unload the ore deposit device.
After giving the ore deposit, strongly magnetic mineral is adsorbed in the separation tube surface under magnetic action, separation tube axon (7) will sub-elect at strongly magnetic mineral when rotating and take the gape place to, unload ore deposit device (3) by roll-type and utilize the effect of induced field to make strongly magnetic mineral break away from the sorting cylindrical shell, and under the centrifugal action that unloads ore deposit roller rotation, get rid of.
