Magnetic separator is a mineral processing machine that separates minerals or mineral aggregates in a magnetic field based on their magnetic differences1. The following is a detailed introduction to magnetic separators:
Classification 1
According to the way the magnetic field is generated: it can be divided into permanent magnetic separators and electromagnetic magnetic separators. Electromagnetic magnetic separators can be divided into two types of magnetic separators: constant magnetic field and alternating magnetic field according to the characteristics of the magnetic field.
According to the strength of the magnetic field: it can be divided into three types of magnetic separators: strong magnetic field, medium magnetic field and weak magnetic field.
According to the separation medium: it can be divided into dry and wet magnetic separators.
According to the structural characteristics: it can be divided into cylinder type, disc type, roller type, belt type, opposite pole type, ring type, etc.
Working principle 1
After the ore slurry flows into the trough through the feed box, under the action of the water flow of the feed water pipe, the ore particles enter the feed area of the trough in a loose state. Under the action of the magnetic field, the magnetic ore particles are magnetically aggregated to form “magnetic clusters” or “magnetic chains”. The “magnetic clusters” or “magnetic chains” are affected by the magnetic force in the ore slurry and move toward the magnetic poles, and are adsorbed on the cylinder. Since the polarity of the magnetic poles is arranged alternately along the rotation direction of the cylinder and is fixed during operation, the “magnetic group” or “magnetic chain” produces magnetic stirring due to the alternation of magnetic poles when the cylinder rotates. Non-magnetic minerals such as gangue mixed in the “magnetic group” or “magnetic chain” fall off during the turning, and the “magnetic group” or “magnetic chain” finally absorbed on the surface of the cylinder is the concentrate. The concentrate moves with the cylinder to the weakest magnetic force at the edge of the magnetic system, and is unloaded into the concentrate tank under the action of the flushing water flow sprayed from the unloading water pipe. If it is a full magnetic roller, the unloading is carried out by a brush roller. Non-magnetic or weakly magnetic minerals are left in the slurry and discharged from the tank with the slurry, which is the tailings.
Basic structure 1
The wet permanent magnetic drum magnetic separator is mainly composed of the following parts:
Cylinder: 2-3mm stainless steel plate is rolled and welded into a cylinder, and the end cover is a cast aluminum part or workpiece, which is connected to the cylinder with stainless steel screws.
Magnetic system: It is an open magnetic system, installed in the cylinder and exposed full magnet. The magnetic block is installed on the bottom plate of the yoke with stainless steel bolts. The shaft of the yoke extends out of the cylinder. A crank arm is fixed at the end of the shaft. The magnetic system deflection angle can be adjusted by turning the crank arm. After adjustment, it can be fixed with a pull rod.
Tank body: The working area is made of stainless steel plate, and the frame and other parts of the tank body are welded with ordinary steel.
Transmission part: The motor drives the cylinder, magnetic roller and brush roller to rotate through a reducer or directly with a stepless speed regulation motor.
Performance characteristics
High gradient magnetic field: Such as the WD series electromagnetic high gradient magnetic separator, it can generate a high gradient magnetization magnetic field, which can effectively select weak magnetic impurities1.
High degree of automation: It adopts programmable control, and the entire production process is fully automatically controlled, which is convenient for changing the process flow, automatic parameter collection, and convenient for production management and quality control1. Large processing capacity: simple structure, large processing capacity, such as wet permanent magnetic drum magnetic separator is suitable for wet magnetic separation of magnetite, pyrrhotite, roasted ore, ilmenite and other materials with a particle size of 0.1-3mm, and can also be used for iron removal of coal, non-metallic minerals, building materials and other materials1.
Application field
Mining: used to separate magnetic minerals from ores, such as magnetite, pyrrhotite, roasted ore, ilmenite, etc., as well as rare earth minerals, seashore placer and other useful minerals1.
Ceramic industry: used to remove ferromagnetic impurities from ceramic raw materials and improve the quality of ceramic products1.
Environmental protection field: used to treat industrial waste and urban garbage, recover ferromagnetic substances therein, reduce environmental pollution, and can also be used for purification of industrial sewage and domestic sewage1.
Food processing: used to remove ferromagnetic impurities from food raw materials to ensure food safety.
Plastic industry: used to remove ferromagnetic impurities from plastic raw materials and improve the purity of plastic products.
