what is magnetic separator
Magnetic separation is a method to separate useful minerals from minerals according to their magnetism.
Magnetic separation is one of the most widely used and mature technologies, which is mainly used for the separation of magnetic minerals. Magnetic separation machine plays an important role in this process.The mined ore is first broken by a jaw crusher, which is broken to a reasonable fineness and then uniformly sent to a ball mill by a hoist and a ore feeder, which crushes and grinds the ore.After the ball mill grinding ore fine material into the next process: grading.The spiral classifier cleans and classifies the ore mixture by the principle that the proportion of solid particles is different and the rate of precipitation in the liquid is different.When the cleaned and graded mineral mixture passes through the magnetic separator, the magnetic substances in the mixture are separated by magnetic force and mechanical force due to the different specific magnetization coefficients of various minerals.Note: this process is designed according to the standard process and can be optimized according to the annual output and requirements of customers.

Strong magnetic minerals: magnetite, pyrrhotite, etc.Medium magnetic minerals: semi - pseudomorphic hematite and some ilmenite, chromite, etc. Weak magnetic minerals: hematite, limonite, carbonatite, ferromanganese, pyrolusite, rutile;Non-magnetic minerals: quartz, feldspar, fluorite, etc.
The above minerals can only be further smelting or other USES after magnetic separation processing, according to the different magnetization coefficient of various minerals, magnetic separation machine with different magnetic field intensity is needed for magnetic separation.

Magnetic separation equipment generally speaking is the magnetic separator.

Magnetic Separator  is usually used for sorting the fine-grained strong magnetic minerals, or removing strong magnetic minerals from non-magnetic minerals. With a deep magnetic field, the machine can make a continuous row of ore feeding and discharge. It also has enough working clearance and high processing capabilities.

Working principle of magnetic separator :
When the ore pulp folw into the magnetic field, the strong magnetic minerals are adsorbed on the surface of the drum. The weak magnetic and non-magnetic minerals are cast off and discharged, while the strong magnetic minerals on the surface of the drum rotate with the drum and will be brought out of magnetic field to complete the sorting operation.

Features of magnetic separator :
1. The magnetic system adopts quality ferrite material and NdFeB magnet.
2. The average magnetic induction of the drum surface is about 100 ~ 600 mT.
3. Downstream tank, half upstream tank,upstream tank or double-drum type can be available.
4. Simple structure, large handling capacity, convenient operation and easy maintenance.

Common knowledge of mineral processing

Common knowledge of mineral processing 1. What is productive rate? In the dressing process, the weight of a product and the percentage of raw ore weight, known as the productive rate. The production rate of each product is calculated as follows: Concentrate mineral rate 1=Q1/Q 100% Medium mineral rate 2=Q2/Q 100% Tail mineral rate 3=Q3/Q 100% Where Q -- raw ore weight, t;  Q1 -- concentrate weight,t; T Q2 -- medium ore weight, t;   Q3 -- tailings weight, t. What is the recovery rate? The concentration recovery is the percentage of the amount of metal (useful component) in the concentrate to the amount of metal (useful component) in the raw ore.This is an important mineral processing index, which reflects the degree of metal recovery, mineral processing technology and mineral processing quality.The recovery of ore dressing should be improved as much as possible on the premise of ensuring concentrate grade.The calculation method is as follows: 3. What is the Ore dressing ...

How much is a set of quarry plant, what equipment does it use? As we all know, gravel is a common material such as construction materials and highway construction materials. The plant mining gravel is called gravel yard, and the plant processing gravel is called gravel yard or stone factory. Granite is about 120~200MPa.Primary crushing usually adopts jaw crusher , which uses the extrusion and bending effect of two jaw plates on materials, crushes the crushing machinery of various hardness materials.The secondary crushing usually adopts impact crusher to produce the particle size of materials.SHUOSEN machine to recognize 300 tons per day of 300mm counterattack crusher feed particle size, discharging size and shape can be adjusted according to customer demand for multi-functional.In addition to the impact crusher, also can choose SHUOSEN machine spring crusher, cone crusher. Main factors for equipment selection can be summarized as follows: (1) the crusher is stable with continuous fee...

How to reduce the dust of jaw crusher

How to reduce the dust of jaw crusher ? Source of jaw crusher dust Dust is initially caused by ore crushing, part of which is carried by the ore itself, and part of which is generated in the later stage of ore crushing.The general movement trajectory of the ore is as follows: the ore enters the machine from the feed port, is broken to the relevant particle size in the machine, is discharged from the discharge port, and then is transported to the next section of processing equipment by the belt conveyor.It can be seen that the devices that directly contact dust with air are inlet, outlet and belt conveyor.In addition, the use of hopper, protective cover, chute and other materials in the production process will produce a certain height difference, which is another major cause of dust. To solve the problem of jaw crusher dust , the first is to control the dust source with the help of external force to avoid its diffusion, and the second is to improve the local structure of the machin...
