magnetic separator and permanent magnet

The magnetic separator uses the magnetic difference between minerals for sorting, plays the role of improving the grade of ore, purifying solid-liquid materials, and recycling waste. It is the most widely used and highly versatile machine in the industry. One.

Magnetic separators are widely used in mining, wood, kiln, chemical, food and other industries. For mining, the magnetic separator is suitable for wet or dry magnetic separation of manganese ore, magnetite, magnetite, roasted ore, ilmenite, hematite and other materials with a particle size below 50mm. , Non-metallic mines, building materials and other iron removal operations and waste disposal operations

The magnetic separator (take wet permanent magnetic cylinder magnetic separator as an example) is mainly composed of 6 parts: cylinder, magnetic roller, brush roller, magnetic system, tank and transmission part. The cylinder is welded into a cylinder by 2-3mm stainless steel plate, and the end cover is cast aluminum or workpiece, which is connected to the cylinder with stainless steel screws. The motor drives the cylinder, magnet roller and brush roller to rotate through a speed reducer or a step-less speed regulating motor.

After the ore slurry flows into the tank through the ore feed box, the ore particles enter the ore feeding area of the tank in a loose state under the action of the water flow of the ore spray pipe. Under the action of the magnetic field, the magnetic ore particles are magnetically aggregated to form a magnetism group or magnetism chain. The magnetism group or magnetism chain is subjected to a magnetic force in the slurry and moves toward the magnetic pole and is adsorbed on the cylinder . Since the polarities of the magnetic poles are alternately arranged along the direction of rotation of the cylinder and are fixed during operation, the magnet or flux rotates with the cylinder, and the magnetic stirring phenomenon occurs due to the alternating magnetic poles and is mixed. The non-magnetic minerals such as gangue in the magnetism or magnetism chain fall off during the tumbling, and the magnetism or magnetism chain that is eventually attracted to the surface of the cylinder is the concentrate. The concentrate is transferred to the weakest part of the magnetic system edge with the cylinder, and it is discharged into the concentrate tank under the action of the flushing water sprayed from the unloading water pipe, and the non-magnetic or weakly magnetic minerals are left in the slurry and discharged out of the tank with the slurry , That is tailings.

Dry magnetic separator: Separation in the air, mainly used to separate large and coarse particles of strong magnetic ore and fine particles of weak magnetic ore. At present, it is also trying to sort fine ferromagnetic ore;

In addition, it can be classified according to the way the magnetic ore particles are selected, the movement direction of the feed material, the method of discharging the selected products from the selected section, and the structural characteristics of the discharged magnetic products.

The closed circuit through which magnetic flux is concentrated is called a magnetic circuit. The magnetic system of the magnetic separator needs to generate a certain intensity of magnetic field, and most of the magnetic flux in the magnetic field can be concentrated through the separation space. The height, width, radius and number of poles of the magnetic system, the magnetic potential difference between adjacent poles, the pole distance, the width of the pole face width and the pole gap width, the shape of the pole and pole face, and the pole face to the center of the arrangement The distance and so on have no small effect on the magnetic field characteristics.

The magnetic separator shown in the following figure is an example. The magnetic circuit part adopts a five-pole magnetic system. Each magnetic pole is formed by bonding a ferrite and a neodymium-iron-boron permanent magnet block. It is fixed to the magnetic guide plate with a screw through the center hole of the magnetic block On the upper side, the magnetic guide plate is fixed on the shaft of the cylinder through the bracket, the magnetic system is fixed, and the cylinder can rotate. The polarities of the magnetic poles are alternately arranged along the circumference, and the polarities are the same along the axial direction. Outside the magnetic system is a roller made of stainless steel non-magnetically conductive material. The non-magnetically conductive material is used to avoid that magnetic lines of force cannot enter the selected zone through the cylinder and form a magnetic short circuit with the cylinder. The part of the tank close to the magnetic system should also be made of non-magnetic materials, and the rest should be ordinary steel plates or hard plastic plates.

For the permanent magnet separator, the permanent magnet is the most important component, and the quality of the permanent magnet determines its performance characteristics. The permanent magnets of magnetic separators are generally made to a certain size (for example, length width height = 85 65 21 mm), so they are traditionally called permanent magnet blocks or magnetic blocks for short. The permanent magnet materials that can be used in the magnetic system of the magnetic separator include permanent magnet ferrite, aluminum nickel cobalt, iron chromium cobalt and manganese aluminum iron, samarium cobalt permanent magnet materials, and neodymium iron boron permanent magnet materials. At present, the mainstream permanent magnetic materials used in domestic magnetic separation equipment are mainly permanent ferrite (strontium ferrite, barium ferrite), followed by neodymium iron boron permanent magnetic materials.

In the design of the magnetic system, it is necessary to choose which permanent magnetic material to use according to the specific conditions of various aspects. The influencing factors can be summarized into the following aspects:

Magnetic field strength: A constant magnetic field must be generated in the designated workspace. The strength of this magnetic field determines which permanent magnetic material is required. The magnetic properties of NdFeB permanent magnets are much higher than ferrites.

eriez - permanent magnetic drum separators

Eriez Drum Separators remove both large and small pieces of iron contaminants from material processing lines. Powerful permanent magnets enable more efficient separation performance for a broader range of applications than ever before. The complete line includes standard models in diameters from 12 to 36 inches (305 to 915 mm), and widths from 12 to 60 inches (305 to 1525 mm). These units provide efficient separation on volumes up to 25,600 cubic feet (725 cubic meters) per hour. They provide years of troublefree automatic removal of tramp iron from heavy flows of bulk materials, including large and highly abrasive materials.

As material reaches the drum, the magnetic field attracts and holds ferrous particles to the drum shell. As the drum revolves, it carries the material through the stationary magnetic field. The nonmagnetic material falls freely from the shell, while the magnetic particles are held firmly until they are carried out of the magnetic field.

Type CC Model Drum Separators have a unique criss cross magnetic circuit. A powerful permanent magnetic field uniformly covers the entire drum width to ensure maximum tramp iron removal. The smooth stainless steel shell with single wiper strip assures positive tramp iron discharge and a minimum of product carryover on powdery or cohesive materials.

Rare Earth Drum Separators should be used for applications where a high degree of product purity is required. Rare Earth Drums are effective in removing very fine ferrous particles, locked particles, and even strongly paramagnetic particles. Magnetic lines of flux are concentrated in each internal pole, creating an extremely highgradient magnetic field.

Type A AgitatorType Drum Separators automatically removes difficulttoseparate magnetic contamination from nonmagnetic materials. This Drum (available with or without HFP housing) has a specially designed magnetic element that causes agitation of materials passed over it. The agitation moves the material in and out of a set of magnetic fields, and thereby physically shakes nonmagnetic materials from ferrous materials, even when entangled.

The permanent magnetic drum separator is suitable for the separation of fine-grained magnetic minerals in metallurgical mines and concentrators, or for the removal of mixed magnetic minerals in non-magnetic minerals.

The surface magnetic field intensity of the permanent magnetic drum separator is much higher than that of the ordinary permanent magnetic separator, which is easy to operate, manage and maintain. The processing capacity is usually 24T/H-240T/H.

After the pulp flows into the tank through the ore feed tank, under the action of the water spray pipe, the ore particles enter the ore area in a loose state. In the magnetic field, The magnetic ore particles are magnetically aggregated to form magnetic clusters or magnetic chains. The magnetic clusters or magnetic chains are magnetically moved in the slurry to move toward the magnetic poles and are adsorbed on the cylinder, and the non-magnetic minerals such as gangue adsorbed on the cylinder fall off during the overturning, and the magnetic clusters or magnetic chain adsorbed on the cylinder surface is the concentrate.

Under the action of pulp flow in the tank body, non-magnetic ore particles and weak magnetism ore particles flow into the tailing pipe from the tailing hole on the bottom plate. The pulp is fed continuously, and the concentrate and tailings are discharged continuously to form a continuous separation process.

The feeding direction of pulp is the same as that of the drum, the concentrate is discharged on the other side, and the tailings is discharged directly at the bottom, which is generally used for 6-0mm strong magnetic minerals.

Features: The downstream magnetic separator has a bigger processing capacity, which is suitable for the roughing and selection of coarse and strong magnetic materials, and can also work in series. When the amount of ore is large, the magnetic ore is easy to lose, so we should strengthen the operation management and control at a lower pulp level.

The feeding direction of ore slurry is opposite to that of the drum. The concentrate is discharged from the feeding side, and the tailings are discharged from the other side. It is generally used in 0.6-0mm strong magnetic minerals.

Features: The countercurrent magnetic separator is suitable for the coarse and sweep separation of fine and strong magnetic minerals. The recovery is high, but the concentrate grade is low. Because the coarse material is easy to deposit and block the separation space, the countercurrent magnetic separator is not suitable for coarse materials.

The feeding direction of half of the pulp is the same as that of the barrel, and the other half is the opposite. The difference with the downstream type is that the pulp rotates in a circle in the tank.

The slurry is washed loose by water to prevent inclusion, and the movement direction of pulp is consistent with the magnetic direction, which is conducive to the recovery of 0.5-0mm strong magnetic minerals.

wet drum permanent magnetic separator manufacturer, supplier in india

Jaykrishna Magnetics manufactures wet drum separator which is used to remove very fine magnetizable components from low concentration, low-viscosity liquids. The wet drum separator is intended for use in the metal processing industry and for the treatment of pre-concentrates extracted from the high gradient magnetic filter. In wet drum separator, around 90% of the grain sizes ranging from 1 m to 1000 m can be separated as sludge.

The liquid flows through a semicircular separating chamber beneath a stainless steel drum to which the magnetisable particles are attracted. The strong, high-gradient magnetic field is created by a cylinder consisting of permanent magnetic discs positioned within the drum. These special permanent magnets generate particularly high field gradients which are necessary for successful separation, as is the need with all magnetic separators.

For recovering magnetic / ferrosilicon in dense media plants and iron ores wet drum separators are primarily used. They remove contaminants from the product stream, increasing product purity and plant productivity. In the applications where the product purity is most essential, the wet drum separators can use powerful rare earth magnets which can remove very fine and weak contaminants even from dense materials.

The liquid flows through a semicircular separating chamber beneath a stainless steel drum gather is a semicircular separating chamber through which the liquid flows.
