Abstract
A fine particle-grade magnetic iron ore dry separator relates to a magnet iron ore drying separating device, which is essentially designed to solve the problem of fine grade size magnetic birdnesting bundling gangue of the prior magnetic iron ore dry separator. The dry separator comprises a framework, a front sealed plate, an outer sealed plate, and a bin. The framework is divided into three layers, such as an upper layer, a middle layer, a lower layer, each layer is provided with a magnetic roller and a tail roller which are connected through a belt, wherein a debris chute, a debris hopper, and a clean ore feeding hopper are further provided. The adjacent bed magnetic rollers are connected by a belt and a vibrating bunk-feeder is installed under the hopper. The magnetic roller in the lower layer of the framework is connected with the variable-frequency control motor arranged on the framework through the belt. A debris remover is arranged under the upper, middle and lower layer magnetic roller, an air inducing pipe and a high pressure draught fan are communicated at the rear portion of the debris remover. The magnetic iron ore dry separator of the utility model has the advantages that magnetic birdnesting phenomenon is reduced, the high pressure draught fan can effectively clean the debris on the magnetic roller by the debris remover, and the clean ore grade is enhanced 3-10 % compared with the current magnetic iron ore dry separator, then standard ore grade is achieved.
Description
[technical field]
The utility model relates to a kind of magnetic iron ore dry separation equipment.
[background technology]
Existing magnetic iron ore dry-dressing machine exists fine fraction (more than 200 orders) magnetic coagulation parcel gangue (mine tailing) problem, the concentrate grade that influence is selected.
[summary of the invention]
The purpose of this utility model provides a kind of fine fraction magnetic coagulation that can solve and wraps up the gangue problem, improves the fine fraction magnetic iron ore dry-dressing machine of concentrate grade.
Above-mentioned purpose is achieved in that same as the prior art is its also organic frame, preceding closure panel, the covering closing plate, be divided in the frame, in, following three layers, the frame top of the upper layer has hopper, on the frame of hopper below dispenser is arranged, on the frame of dispenser below magnetic roller and tail roller are arranged, connect with belt between magnetic roller and the tail roller, in frame middle level and lower floor the mine tailing chute is arranged, there is the mine tailing hopper mine tailing chute below, magnetic roller and tail roller also are housed respectively on the frame of middle level and lower floor, and connect with belt, on the frame, in, all there is the concentrate hopper each layer magnetic roller below down, have belt to connect between the magnetic roller of adjacent bed and the magnetic roller, the motor on the magnetic roller of frame lower floor has belt and is contained in frame connects; The dispenser that different is here is a shocking feeder; It is frequency control motor that belt and the joining motor of magnetic roller are arranged.
In order to improve concentrate grade better, we adorn the mine tailing remover below each layer magnetic roller, mine tailing remover front end has opening towards magnetic roller direction, and the rear internal diameter of opening strengthens and forms a cavity, and there are air inducing pipeline and the high-pressure suction fan UNICOM that is contained on the frame in the rear portion, chamber.
[description of drawings]
Accompanying drawing is a structural representation of the present utility model.
[specific embodiment]
With reference to accompanying drawing, closure panel 2 before the front of frame 9 has, side has covering closing plate 11, be divided into upper, middle and lower-ranking in the frame, at the top on frame upper strata hopper 1 is housed, on the frame of hopper below shocking feeder 10 is housed, on the frame of shocking feeder below magnetic roller 3 and tail roller 13 is housed, have belt 14 to connect between magnetic roller and the tail roller; Near preceding closure panel direction mine tailing chute 4 is arranged in frame middle level and lower floor, there is mine tailing hopper 6 mine tailing chute below; Magnetic roller 3 and tail roller 13 also are housed respectively on the frame of middle level and lower floor, also there is belt 14 to connect between magnetic roller and the tail roller, below each layer magnetic roller of frame upper, middle and lower, concentrate hopper 5 is arranged all, have belt 14 to connect between the magnetic roller of adjacent bed and the magnetic roller, the magnetic roller of frame lower floor has belt and the frequency control motor 12 that is contained on the frame to link.
In addition, we establish mine tailing remover 7 below each layer magnetic roller of frame upper, middle and lower, and mine tailing remover front end has opening towards magnetic roller direction, and the rear internal diameter of opening strengthens coelosis, and there are air inducing pipeline and high-pressure suction fan 8 UNICOMs that are contained on the frame in the rear portion, chamber.
The utility model has the advantages that: the vibrations feed, frequency control belt magnetic roller reduces the magnetic coagulation phenomenon; High-pressure suction fan has been removed mine tailing (fine-grained gangue) on the magnetic roller effectively by the mine tailing remover, makes concentrate grade improve 3-10% than existing magnetic iron ore dry-dressing machine, reaches qualified grade.
