Working Process
- Generation of magnetic field
An electromagnet usually generates the magnetic field in an electromagnetic pulp magnetic separator. By energizing, the magnetic field generated by the electromagnet can be adjusted in strength and direction, thus adapting to the magnetic sorting needs of different particles. In addition, some high-performance permanent magnets can also be used to generate a stable magnetic field, which has the advantages of energy saving and environmental protection. - Sorting of magnetic particles
When the slurry passes through the magnetic field, the magnetic particles are magnetized and adsorbed in the magnetic pole area, forming magnetic ore;. In contrast, the non-magnetic particles are repelled to the edge of the magnetic field, forming non-magnetic scrap. By adjusting the strength and direction of the magnetic field, the movement trajectory of the magnetic particles can be controlled, thus realizing the effective sorting of them.
Application Prospects
The electromagnetic slurry magnetic separator is widely applied to remove the iron powder, micro-iron powder, magnetic substances, and others contained in the glaze slurry of the ceramics, mining industry, chemistry, food, and other industries.
- Mining industry field
Electromagnetic slurry magnetic separator has a wide application prospect in the field of mining industry. It can be used for beneficiation of ores rich in magnetic minerals to improve the grade and recovery rate of ores and reduce the waste of resources. Meanwhile, for some difficult-selective ores, an electromagnetic slurry magnetic separator can play an important role as an effective separation means. - Environmental protection and waste treatment
In the field of environmental protection and waste treatment, electromagnetic slurry magnetic separator also has potential application prospects. For example, it can be used to deal with magnetic particles in wastewater, reducing pollutants in the environment; at the same time, for some waste containing useful magnetic materials, an electromagnetic slurry magnetic separator can realize the effective recovery of resources. - Biomedical
In addition to the mining industry and environmental protection, electromagnetic slurry magnetic separators in the biomedical field also have potential application prospects. It can be used in cell sorting, drug delivery, etc. to support biomedical research and treatment.
How to Operate an Electromagnetic Slurry Magnetic Separator?
The electromagnetic slurry magnetic separator is required to connect the power supply unit, open the slurry inlet valve and slurry outlet valve, close the back-slurry valve and iron dumping valve, and open the magnetizer. When all the slurries pass through the slurry iron remover, it is required to close the inlet valve and slurry outlet valve, open the back-slurry valve, and drain the remaining slurries in the iron remover via the back-slurry valve. Then, it is required to disconnect the magnetic field, close the back-slurry valve, and open the iron dumping valve, to dump the magnetic substances stuck to the magnetic medium.
How to Choose The Right Electromagnetic Slurry Magnetic Separator?
Electromagnetic slurry magnetic separator selection principle
- Magnetic field strength
The magnetic field strength of the electromagnetic slurry magnetic separator is the primary consideration when selecting, generally the greater the magnetic field strength, the higher the enrichment rate. However, the magnetic field strength is too large and may damage the selected materials, affecting production efficiency. In the selection of an electromagnetic slurry magnetic separator, according to the nature of the material, magnetic size, and other factors, a reasonable choice of magnetic field strength. - Production capacity
Production capacity is another important factor to consider when choosing an electromagnetic slurry magnetic separator, in general, the larger the production capacity, which means that the cost of equipment selection and operating costs will be increased accordingly. When choosing equipment, you need to choose according to the actual production demand and output. - Magnetic drum diameter and length
Magnetic drum diameter and length are also one of the factors to be considered when choosing an electromagnetic slurry magnetic separator. In general, the larger the diameter and length of the magnetic drum, the greater the magnetic field strength. However, the increase in diameter and length also means an increase in investment costs, so you need to weigh the pros and cons according to production needs. - Power control mode
Power control mode is also one of the factors to be considered when choosing an electromagnetic slurry magnetic separator. Common control methods are constant shell type, multi-stage transformer, frequency control, and so on. Need to select a reasonable control mode to ensure the stable operation and productivity of the equipment.
Electromagnetic slurry magnetic separator selection considerations
When choosing an electromagnetic slurry magnetic separator, you also need to pay attention to the following aspects:
- Reasonable selection of equipment models according to production requirements and power consumption.
- Understand the structure and performance parameters of the equipment, and choose a suitable manufacturer.
- When selecting equipment, special attention needs to be paid to the wear resistance and corrosion resistance of the equipment to ensure that the equipment can run stably for a long time.
- When maintaining the equipment, you need to follow the operating procedures and pay attention to maintenance and replacement of wearing parts.
Electromagnetic slurry magnetic separator selection and application need to pay attention to a variety of factors, however, the most critical is still according to their own production needs and the actual situation, to choose the right model of magnetic separator. As a professional magnetic separator manufacturer, JXSC mineral according to the specific conditions of the customer’s materials and production capacity for the selection, can facilitate better use of customers, and reduce the cost of trial and error.
