Magnetic separation is a physical method for separating magnetic minerals from nonmagnetic minerals by using magnetic differences among the minerals. In the magnetic separation process, the bulk dry magnetic pulley is a commonly-used mineral separation device, and is widely applied to pre-dry magnetic separation after raw ore crushing due to the advantages of relatively simple structure, low production cost, reliable operation and the like, and has the main functions of: the surrounding rocks and waste rocks mixed into the raw ore in the mining operation are abandoned, the circulating quantity of the crushing operation is reduced, the ore grade entering the ore mill is improved, and the ore milling cost is reduced.
However, in the mixed material layer of different magnetic ores, due to the influence of different physical acting forces such as magnetic field force, belt-transported inertia force, acting force between ores, etc., the separation effect of dry-type magnetic separation operation is reduced, the separation effect is affected, and resource waste is caused.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the purpose is exactly in order to solve the poor problem of current dry-type magnetic separation device separation effect, provides a device for magnetite dry-type magnetic separation, can carry out the layering magnetic separation to the magnetite, has improved the effect of selecting separately effectively, has avoided the waste of resource.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a device for magnetite dry-type magnetic separation, includes band conveyer, and band conveyer's one end is equipped with dry-type magnetism pulley.
The two belt conveyors are respectively a first belt conveyor positioned above and a second belt conveyor positioned below, and the second belt conveyor is arranged below one end of the dry-type magnetic pulley of the first belt conveyor;
a first ore separation funnel is arranged between the first belt conveyor and the second belt conveyor, the upper opening of the first ore separation funnel faces the lower part of the dry magnetic pulley of the first belt conveyor, and the lower opening of the first ore separation funnel faces the second belt conveyor;
be equipped with two first minute ore baffles in the first minute ore funnel, first minute ore baffle is with first minute ore funnel inside being divided into three first chute to handle and separate magnetic ore, middlings, the non-magnetic ore after the first layer is selected separately.
In order to realize the utility model discloses an above-mentioned device is used to carry out the method of ferromagnetic ore dry-type magnetic separation still is provided, its characterized in that:
when ferromagnetic ore passes through a dry magnetic pulley of a first belt conveyor, the ferromagnetic ore is separated by the dry magnetic pulley and then thrown into a first ore separating funnel along the movement direction of a belt, magnetic ore, middling ore and non-magnetic ore respectively fall onto a second belt conveyor below through three first chutes in the first ore separating funnel, the non-magnetic ore, the middling ore and the magnetic ore are distributed on the second belt conveyor in an upper layer, a middle layer and a lower layer in a layered mode, and finally the dry magnetic pulley of the second belt conveyor is used for separation.
The technical scheme of the utility model, use through the cooperation of dry-type magnetic pulley and first minute ore funnel, ferromagnetic ore is thrown under belt transport's inertial force and magnetic drum's magnetic force, because magnetic ore is heaviest, therefore thrown more nearly, and non-magnetic ore throws more far away, thereby discharge through different first chutes in first minute ore funnel, fall into behind the second belt conveyor, because magnetic mineral is in the lower floor, middling is at the middle level, non-magnetism is on the upper strata, thereby reduce magnetic mineral to middling and non-magnetic ore, perhaps middling is to the mutual interference effort of non-magnetic iron ore, improve the sorting effect of dry-type magnetic separation operation from this.
