There are many factors affecting the operation of the permanent magnetic cylinder magnetic separator. In addition to the bottom box type, magnetic structure and magnetic field characteristics, there are magnetic system declination, working gap, sorting concentration and cylinder rotation speed.

6. Central Fume Extraction System
1) Cantilever type fume extraction system
Cantilever dust removal can be used for manual welding conditions where the work stations are evenly distributed and the span is small. The smoke and dust generated by each welding station can be effectively absorbed at the dust generation point, and will not pollute other parts of the workshop. The skeleton of the suction arm is similar to a human arm and can hover in a space within a certain length. The outer layer of the suction arm is a temperature-resistant hose, which not only prevents the hose from being burned by sparks, but also ensures the flexibility of the movement of the suction arm. A unique rotating structure is designed on the position of the Suction Hood to ensure that the suction hood can be aligned with the welding position in any orientation, so that the suction arm can effectively capture the smoke and dust generated during the welding process. The advantage of the suction arm capture is that it can be close to the place where the smoke is generated, and the collection effect is better.
2) Hood suction type fume extraction system
Cantilever dust removal can be used for manual welding conditions where the work stations are evenly distributed and the span is small. The smoke and dust generated by each welding station can be effectively absorbed at the dust generation point, and will not pollute other parts of the workshop. The skeleton of the suction arm is similar to a human arm and can hover in a space within a certain length. The outer layer of the suction arm is a temperature-resistant hose, which not only prevents the hose from being burned by sparks, but also ensures the flexibility of the movement of the suction arm. A unique rotating structure is designed on the position of the suction hood to ensure that the suction hood can be aligned with the welding position in any orientation, so that the suction arm can effectively capture the smoke and dust generated during the welding process. The advantage of the suction arm capture is that it can be close to the place where the smoke is generated, and the collection effect is better.
3) Room tupe fume extraction system
Room-type dust removal is suitable for the purification of fumes and smoke generated during the production of automated equipment, such as welding robots, welding machines, grinding, grinding and polishing of metal and plastic parts, drilling, thermal processing, cutting and crushing, stone processing, powder packaging, solid particles and various dusts and fumes produced by mixing and processing.
For working conditions such as robot automatic welding, circular seam and longitudinal seam welding, the smoke and dust purifier is installed with the robot workstation, so that the workstation has its own dust removal function. The fume and smoke are effectively collected through equipment components such as pipes and dust hoods. The room-type design prevents the volatilization and diffusion of smoke to keep the air in the workshop clean.
The working conditions with moderate welding workpieces and large amounts of dust and smoke are suitable for room-type treatment solutions. The room type centralized dust dedusting solution is divided into side suction and top suction method dust collecting ways. The appropriate solution can be designed according to the site conditions and treatment goals.
4) Blow suction type fume extraction system
Blow-suction type dust removal solution is a ventilation air flow composed of blown air and inhaled air flow. Therefore, it is a dust removal method that can effectively control the spread of pollution sources. This dust removal method is installing exhaust inlets on two-span center column or single-span side column (wall) and air outlets on the opposite wall column to form a circulating air flow to drive the smoke and dust into the purification machine, consequently performing overall dust removal and purification in the workshop. This system occupies a small area and has obvious purification effect, which is suitable for the purification of smoke and smoke in more complex production workshops.

If the magnetic system declination is not appropriate, it will obviously affect the sorting index. The so-called magnetic system declination is the angle between the center line of the magnetic system arc surface and the vertical line of the cylinder center. After the magnetic system, the tailings grade is low, but after the large deviation, the grade of the tailings is increased because the concentrate cannot be lifted to the concentrate end. If the magnetic system is ahead of the head, the concentrate will be lifted too high, the sweeping area will be shortened, and the tailings grade will be raised, so the magnetic system declination should be adjusted to a moderate position.
The distance between the cylinder surface of the rough selection zone and the bottom plate of the tank is called the working clearance. The size of the working gap will affect the effect of sorting. A large gap, a large flow of the slurry also help to improve the processing amount, but far away from the cylinder surface, a lower magnetic field strength, the tailings grade will raise, lower metal recovery. Conversely, if the working gap is small, increasing the magnetic field force will lower the concentrate grade, but the recovery rate can be higher. If the working gap is too small, the slurry flow rate will be too fast, so that the ore particles can not be sucked to the surface of the cylinder and will be brought to the tailings by the slurry flow, which will cause the tailings grade to rise, and even the tailings will be difficult to discharge. "phenomenon. Therefore, care should be taken to ensure proper working clearance during the installation and maintenance of the magnetic separator.
The size of the sorting concentration determines the slurry flow rate of a certain amount of minerals, which affects the sorting time of the ore particles. The concentration is high, the flow rate is slow, the resistance is large, and the gangue is easily mixed in the concentrate to reduce the quality of the concentrate. However, due to the long selection time, it is beneficial to the recovery rate. If there is a low concentration, the concentrate grade can be higher, and the tailing grade will also increase, which will reduce the recovery rate.
The size of the cylinder rotation speed also has an influence on the selection index, and the rotation speed is low and the output is low. The high speed, the centrifugal force of the ore particles is large, the magnetic turnover effect per unit time increases, the concentrate grade and processing capacity are high, and the recovery rate is reduced.
In practice, it is important to adjust the blown water of the ore to the rinse water of the concentrate. The blown water is too large, and the pulp flow rate is too fast, which will increase the grade of the tailings. On the contrary, the small amount of blown water will make the ore particles not fully loose and affect the sorting effect, so that the tailings grade will increase and the concentrate grade will decrease.
The concentrate flushing water is mainly used to remove the concentrate from the barrel, and the size of the flushing water should be able to ensure that the concentrate is discharged.
