The basic structure of magnetic separator

Wet permanent cylinder type Automatic Glaze Separator is mainly composed of cylinders, rollers, brush rollers, magnetic systems, tank and drive section consists of 6 parts.Cylinder made of 2-3mm stainless steel plates welded tube, end cap for cast aluminum parts or workpieces, using stainless steel screws and cylinder is connected.Motor through reducer or directly with infinite speed motor drive cylinder, magnetic roller and brush roll for rotational motion.Magnetic Grids&Tubes systems for open-magnetic system, magnet, mounted on a cylinder and bare.Magnets mounted on the yoke base plate stainless steel bolt and yoke shaft out of the cylinder, shaft end is fixed with crank arm.Flipping the crank arm adjustment magnetic declination, adjust the appropriate levers can be used after fixed.Working area with stainless steel plate manufacture of tank, frame and other parts of the tank using ordinary steel welding.

Counterflow separators

High Frequency Vibrating Sieve suitable for fine-grained magnetic minerals in the rough election and sweep the election operation, high recovery and concentrate grade is lower.Because coarse sediment clogging separation space, so the counter-current type magnetic separator is not suitable for coarse material.Upstream and a half can get high quality iron concentrate of magnetic ferrous traps machine, but also to get a better rate, a half upstream separators are widely used in practice.It is suitable for handling 0.5mm roughing and a selection of the following mineral grains, can also be multiple serial and parallel, multiple-scan election and selection.

-Flow separators processing capacity

-Flow New magnetic roll separator processing capacity, suitable for coarse-grained magnetic materials rough election and selection, also more than one series.-Flow separators when feeding a large quantity, coolant magnetic separators particles easily lost in tailings, and therefore to strengthen the operation management, controlled lower pulp level.

Methods of measurement of magnetic field strength wet permanent magnetic drum magnetic separator as follows:

(1) selection of three sections along the cylinder axis: one option in the middle, the other two sections were taken at a distance of 200mm at each end.
(2) in each section to measure the magnetic field intensity slip separator surface a number of key points, usually the edge of each pole and a total of three points in the middle (the magnetic system edge 2:00 eventuality), the middle of a cusp point, if the number of poles is n, then the measurement points N = [3n-2+ (n-1)] = 4n-3. As 3-pole magnetic system to 9 points, 4-pole magnetic system to 13 points, more than analogy.
(3) the average of the cylindrical surface of the magnetic field strength on behalf of the cylindrical surface of the magnetic field strength measured at various points, the same way, from the cylinder surface magnetic field intensity magnetic pulley separator certain height of each point of the average representative of the magnetic field strength of the arc.
(4) a certain distance away from the key points of the top of the cylindrical surface on each section measuring 3 to 5 points. As from the drum surface 10mm, 20mm, 30mm, 40mm, 50mm each point.
Before measurement, the first cylinder (and magnetic system) support from, in order to measure the height as appropriate. At this point magnetic system vertically downwards, but we do not see the poles at the outer cylinder, measuring point given inaccurate sprinkle some iron in the cylindrical outer magnetic pole attracting iron edge
More magnetic separator magnetic pole shape can be displayed. If you do not iron, can also be used to find some nails, nails can stand in the place that is the cylindrical surface of the magnetic pole center (or center CUSP), to find the exact location later be marked with chalk or a brush, and then Point by point measurements.

Wet permanent cylinder type magnetic separator

 Wet permanent cylinder type Neodymum magnetic drum separators is iron ore dressing plant commonly used a magnetic separator, it is suitable for separating strongly magnetic minerals.According to the different tank type, New magnetic roll separator-divided-flow, counter-flow, upstream and a half three.Three different slot size of magnetic separator selected particle size are as follows: concurrent flow tank ≤ 6mm, backflow tank ≤ 1.5mm, upstream and a half tank ≤ 0.5mm.

Classification of magnetic separator

In accordance with the type of magnet points can be divided into: permanent magnet easy-cleasing magnetic traps and electromagnetic iron-removing machine
According to the mine's classification can be divided into wet and dry: dry in addition to iron, iron removal from wet machine
Classification according to the magnetic system can be divided into: drum magnetic separator machine, roller-type magnetic separator and cylinder roller-type magnetic separator and plate separators.
According to the magnetic system the number of categories can be divided into: single cylinder magnetic separator, dual cylinder ceramic magnetic separator and combined multiple cylinder magnetic separator.

According to classification of mining methods can be divided into: the upper ore separators, proximal to mineral magnetic separator.
In accordance with the classification of magnetic field strength can be divided into: weak magnetic magnetic separator, magnetic separators and strong magnetic separator.
In accordance with the classification of magnetic systems can be divided into: open magnetic circuit of magnetic separator, closed magnetic circuit magnetic separator.

Magnetic separator (magnetic separator) introduction

Lot of mineral dry drum magnetic separator can be sorted such as magnetite, limonite, hematite, manganese siderite, ilmenite, wolframite, manganese ore, manganese carbonate ore, metallurgy of manganese ore, manganese oxide ore, iron ore, kaolin and rare earth mineral magnetic separator can be used for sorting.coolant magnetic separators process is in the magnetic field in magnetic separators, by means of magnetic force and mechanical force on the particle to achieve separation.Different magnetic particles along a different trajectory, thus separating into two or more separate selected mineral products

Scope of application of the magnetic separator

• Fine magnetic filter bars grained clay minerals (kaolin, bauxite, and so on) is refined: remove dyeing of fine weakly magnetic impurities in the clay mineral particles (Fe2O3, TiO2);
• Reduction of quartz, feldspar, barite Fe2O3 content;
• Decreasing copper content in molybdenum concentrate;
• Coal ash removal of sulphur;
• Improve the quality of apatite;
L, beach placer deposits of rare earth minerals and other valuable mineral collection;
• Continuously to remove abrasive particles in lubricating oils and lubricating oil recovery and recycling;
• Chemical, coolant magnetic separators apparatus and liquid filtration of the oil industry, recycling and purification catalysts and other useful items;
L nuclear power plant and power station feedwater and condensate filters;
• Purification of industrial waste water and domestic sewage;

Technical characteristics of magnetic separator
