Introduction to magnetic separator

Below we introduce the scope of application of the magnetic separator, the type of mineral processing applicable, the composition of the magnetic separator and the workflow of the magnetic separator.

The scope of application of magnetic separator:

Magnetic separator suitable particle size, wet magnetic separation of iron ore, pyrrhotite, roasted ore, titanium, iron ore and other materials below 3mm, but also for coal, non-metallic minerals, building materials like iron work.

The type of mineral processing suitable for the magnetic separator:

The magnetic separator can sort a lot of minerals such as: magnetite, limonite, hematite, manganese siderite, ilmenite, wolframite , manganese ore, manganese carbonate ore, metallurgical manganese ore, manganese oxide ore, iron ore, Kaolin , rare earth ore, etc. can be selected by magnetic separator. The magnetic separation process is carried out in the magnetic field of the magnetic separator by means of the action of magnetic force and mechanical force on the ore particles. Different magnetic ore particles move along different trajectories and are sorted into two or more separate beneficiation products.

The composition of the magnetic separator:

The magnetic separator is mainly composed of a cylinder, a magnetic system, a tank body and a transmission part.

Welded into a tubular cylinder made of stainless steel coil 2-3mm, cast aluminum cover member is connected with stainless steel screws and cylinder. The motor drives the cylinder to make a rotary motion through the reducer.

The magnetic system is an open magnetic system and is housed in a cylinder. The magnetic block is mounted on the bottom plate of the yoke with stainless steel bolts, the shaft of the yoke protrudes out of the tube, and the arm end is fixed with a turning arm. Pull the arm to adjust the magnetic system yaw angle. After adjustment, it can be fixed with the lever.

The working area of ​​the tank is made of stainless steel, and the rest of the frame and the tank are welded with ordinary steel.

The working process of the magnetic separator is as follows:

After the slurry is fed into the tank by the ore tank, the ore particles enter the tank feeding area in a loose state under the action of the water flow to the mine sprinkler pipe. Under the action of a magnetic field, the magnetic ore particles are magnetically aggregated to form a "magnet" or "magnetic flux". The "magnet" or "magnetic flux" is magnetically applied to the slurry and moves toward the magnetic pole, and is adsorbed on the cylinder. . Since the polarities of the magnetic poles are alternately arranged in the direction of rotation of the cylinder, and are fixed during operation, the "magnet" or "magnetic flux" is magnetically agitated due to the alternating magnetic poles when being rotated with the cylinder, and is mixed. The non-magnetic minerals such as gangue in the "magnet" or "magnetic flux" fall off during the flipping, and the "magnet" or "magnetic lotus" that is finally attracted to the surface of the cylinder is the concentrate. The concentrate passes to the weakest point of the magnetic system at the edge of the magnetic system, and is discharged into the concentrate tank under the action of the flushing water jet discharged from the unloading water pipe. If it is a full magnetic magnetic roller, the unloading is performed by a brush roller. Non-magnetic or weakly magnetic minerals are left in the slurry with the slurry exiting the trough, which is the tailings.

YPG pressure spray dryers utilize spray nozzle to atomize the materials to tiny liquid drops, which drop in parallel with the hot air at the top of the tower to finish drying, and transform the materials into powdery or granular products. This pressure spray drying machine is very suitable for drying thermosensitive materials.

YPG pressure spray dryer is broadly used in food, pharmaceutical, chemical, dye, ceramics, biological, pesticide, plastics and other industries. The following are some specific applications:

Spray Drying Granulation
Chemical industry: organic catalyst, resin, synthetic detergent, oil, thiamine, dye intermediate, white carbon black, graphite and ammonium phosphate.
Food: amino acid, spices, protein, starch, dairy products, coffee extracts, fish meal and so on
Pharmaceuticals: Chinese patent medicine, pesticide, antibiotic and dissolved medicines
Ceramics: magnesium oxide, porcelain clay, all kinds of metal oxide, dolomite, etc.
Spray Granulation
Fertilizers, alumina, ceramic powder, heavy metal, granulous detergent and Chinese patent drug
Spray Cooling Granulation
Aliphatic acid, paraffin, olein and oil
In addition, our spray drying machine can also be used in the fields of spray crystallization, spray concentration and spray reaction.
