CTB6012 Wet 20t/H Drum Magnetic Separator Machine and iron ore magnetic separator factory price

Wet permanent magnetic cylinder magnetic separator

Magnetic separator is one of the most widely used and versatile machines in the industry, which is suitable for the separation of substances with magnetic differences [1]. Magnetic separator is widely used in mining, wood industry, kiln industry, chemical, food and other industries. As for mining, magnetic separator is suitable for wet or dry magnetic separation of manganese ore, magnetite, pyrrhotite, roasted ore, ilmenite, hematite and other materials with particle size below 50mm, and is also used for iron removal operations of coal, non-metallic ore, building materials and other materials. Magnetic separator is divided into two categories, the magnetic system of permanent magnet magnetic separator, mostly made of high quality ferrite material or composite with rare earth magnetic steel, earlier, magnetic separator magnetic barrel surface average magnetic induction intensity is 80-400MT. With the continuous development of technology, magnetic separator can be made into a roller, the magnetic field strength also increased to 1650mT, is currently measured the highest magnetic field strength.

Wet permanent magnet drum-type magnetic separator is mainly composed of six parts: cylinder, roller, brush roller, magnetic system, tank and transmission part [1]. The cylinder is made of 2-3mm stainless steel plate and welded into a cylinder. The end cover is a cast aluminum piece or workpiece, which is connected to the cylinder with stainless steel screws. The motor drives the cylinder, magnetic roller and brush roller to rotate through the reducer or directly with stepless speed regulating motor. Magnetic system is open magnetic system, installed in the cylinder and exposed to the full magnetic. The magnetic block is mounted on the bottom plate of the magnetic yoke with stainless steel bolts, and the shaft of the magnetic yoke extends out of the barrel, and the shaft end is fixed with a crutch. Swing arm can adjust the magnetic system deflection Angle, adjust the right can be fixed with a tie rod. The working area of the tank is made of stainless steel plates, and the frame and other parts of the tank are welded with ordinary steel.

Working principle  of magnetic separator

After the slurry flows into the tank through the feeding box, under the action of the water flow of the feeding pipe, the ore particles are loose into the tank to the mining area. Under the action of magnetic field, magnetic ore particles are magnetically coalesced to form "magnetic cluster" or "magnetic chain". The "magnetic cluster" or "magnetic chain" is affected by magnetic force in the pulp, moves towards the magnetic pole, and is adsorbed on the cylinder [2]. Due to the polarity of the magnetic poles along the cylinder rotation direction are arranged alternately, and fixed at work, "magnetic group" or "magnetic chain" in the cylinder rotates, with alternating polarity magnetic stirring, was mixed in the "magnetic group" or "magnetic chain" of the gangue and other non-magnetic minerals in turn off, has finally been sucked on the surface of the cylinder, the "magnetic group" or "magnetic chain" is to concentrate. Concentrate with the cylinder to magnetic system edge magnetic force is weakest, under the action of washing water discharge pipe is discharged into the concentrate tank, if it is full magnetic roller, unloading is carried out with brush roller. Non-magnetic or weakly magnetic minerals are left in the pulp along with the pulp discharge tank, that is, tailings.

Production capacity:10-280t/h

Overview: Magnetic separator can be divided into dry magnetic separator and wet magnetic separator. The magnetic separator is the most widely used mining machine with advantages of simple structure, easy to operate, easy to maintain and so on. The magnetic separator is widely used in iron powder removal, and magnetic separator is also widely used in resource recovery, timber industry, mining, ceramic, chemical, food and so on. The magnetic separator is suitable for wet magnetic separation of magnetite, pyrrhotite, roasted ore, ilmenite and other materials with granularity below 3mm, and the iron removal of coal, non-metallic mineral, building material and other material.

Structure: The magnetic separator is mainly composed of drum, roller, brush roller, magnetic system, tub and transmission parts. Cylinder is rolled welding by 2-3 mm stainless steel plate, and the end cover is aluminum casting connected by stainless steel screw and barrel. Motor regulates motor speed through the reducer, which drives the cylinder and magnetic roll do rotary motion. Magnetic system is open, installed in inside cylinder and all bared magnetic. Magnetic block is installed in the plate of yoke by stainless steel bolt, and the shaft of the yoke is out of the barrel. The end shaft is fixed with turn arm, which can adjust the magnetic system angle. The working area of trough is made up with stainless steel, and the frame and other parts of the cell body is welded with ordinary steel.
