Abstract

An iron fine powder dry magnetic selector comprises a hopper, a composite 'suspended round vibration feeding machine', a rotating non-conductive stainless drum, a fixed magnetic field, a grid current generator, a close type concentrate feed guiding groove and a dedusting system and so on. Magnetic powder that is dry ground into 200 meshes goes through a first to a second selection for selecting iron fine powder, and whole iron content reaches over 62%. The invention can be designed as two-cylinder or three-cylinder structure according to requirements of users, and goes through the second to a third selection in top-down sequence.

Description

Iron concentrate dry magnetic separator
Technical field
The present invention relates to the smart powder magnetic separator of iron that iron ore dressing is used, can from grinding machine is dry grinded 200 purpose magnetite powders, select the smart powder of the iron of all iron content more than 62%, tail row article potential energy is controlled at the iron concentrate dry magnetic separator about 10%.
Background technology
The technical indicator of the smart powder of iron is:
1. granularity requirements: 200 order sieving rates will reach more than 70%;
2. grade requirement: all iron content will reach more than 62%.
The dry powder magnetic separator of domestic production at present can only sort fineness less than 80 purpose coarse granule breezes, can't sort being ground to 200 purpose magnetite powders.The smart powder magnetic separator of traditional iron all is the wet type ore dressing, needs a large amount of water as the ore dressing medium.Ore pulp flows in order to make, filtration etc., needs a lot of equipment, also need consume much electricity simultaneously.
Summary of the invention
The purpose of this invention is to provide a kind of iron concentrate dry magnetic separator, can from the 200 purpose magnetite powders of dry grinding, select the smart powder of the iron of all iron content more than 62%, tail row article potential energy is controlled at about 10%.
Iron concentrate dry magnetic separator of the present invention, said iron concentrate dry magnetic separator comprise not magnetic stainless steel cylinder, fixed magnetic field, grid current generator, enclosed type concentrate deflector chute and the dust pelletizing system of hopper, floated circular vibration dispenser, rotation.
Said hopper connects floated circular vibration dispenser, and the not magnetic stainless steel cylinder of rotation is set under the floated circular vibration dispenser, and floated circular vibration dispenser is to the not magnetic stainless steel cylinder feed of rotation.
The not magnetic stainless steel cylinder of said rotation can be set to two-stage or more than the two-stage.
1. following four is the main innovate point that iron concentrate dry magnetic separator improves the smart grade powder of iron; The smart powder one dried magnetic separator of iron is characterized in that: the air grille flow-generator is the key innovation parts of iron concentrate dry magnetic separator; In ore dressing process; Can break up magnetic coagulation, blow away the mine tailing fine powder that is rolled in wherein, reach the ore dressing purpose of the smart grade powder of further raising iron.
2. closed concentrate deflector chute can effectively prevent, the dust in the ore dressing process carries out secondary pollution to the smart powder of iron, plays an important role to improving the smart grade powder of iron.
3。Indoor design the original creation, integrated-type " floated circular vibration dispenser ", compact conformation, reliable operation.Main effect has following 4 points:
A. can carry breeze to the effective workspace of half magnet drum uniformly, play an important role improving the equipment operating efficiency.
B. by the rotating speed of Frequency Converter Control vibrating motor, can control delivery rate;
C. reduce the airborne dust point, bring convenience to dedusting work;
D. the magnetic breeze there is magnetization in advance, plays an important role improving the rate of recovery.
4. the dust pelletizing system of design has two effects, and the one, compliance with environmental protection requirements, the 2nd, prevent that the high concentrate dust that device interior is kicked up in the ore dressing process from causing secondary pollution to the smart powder of iron, very important to the effect that improves the smart grade powder of iron.
Description of drawings
Accompanying drawing is the iron concentrate dry magnetic separator sketch map:
Like the iron concentrate dry magnetic separator sketch map, iron concentrate dry magnetic separator is by the formations such as not magnetic stainless steel cylinder, fixed magnetic field, grid current generator, closed concentrate deflector chute and dust pelletizing system of hopper, integrated-type " floated circular vibration dispenser ", rotation.
The specific embodiment
The objective of the invention is to realize like this: the 200 purpose magnetite powders of dry grinding; Get into floated circular vibration batcher through hopper, the delivery plate discharge port is apart from magnetic pole 30mm, within the magnetization scope; Magnetite powder is along the delivery plate inclined-plane; In the process of discharge port motion,, make iron ore concentrate that enough magnetizing times arranged, play a role improving the rate of recovery just by magnetization in advance.Batcher with 2800 times/minute vibration frequency evenly to the swing roller feed.Breeze is followed cylinder and is moved in a circle; Under magnetic field force and action of centrifugal force; Namagnetic substance is tangentially dished out; The magnetic breeze is adsorbed on cylinder surface and continues along magnetic field apparent motion under the effect of magnetic field force, field pole is alternately to arrange, and it is magnetic disturbance in the continuous upset one of cylinder surface that alternating magnetic fields power makes breeze.In the process of magnetic disturbance, the association rock particle that is mixed in the Iron Ore Powder is progressively dished out; Concentrate is before the mining area is unloaded in entering, through the air grid current, under the effect of air-spray energy; Break up magnetic coagulation, throw and remove residual mine tailing fine powder, reach the ore dressing purpose of the smart powder of further purification iron; Generally arrive the secondary ore dressing through one, all iron content of the smart powder of iron just can reach more than 62%.Can be designed to two or three barrel structures according to customer requirements, once accomplish two to three grades of ore dressings from top to bottom.

Claims (2)
