Roll Strong Magnetic Separator Tips

The magnetic source system of strong permanent magnetic roller separators adopts high-performance permanent material rare earth neodymium iron boron through the combination of polymerization. The strong magnetic separator has the advantages of a light model, high magnetic field strength, low energy consumption, stable performance, and wide applicability. The permanent magnetic separator is used for the magnetic separation of poor manganese ore, each processing of one ton of manganese ore only needs to consume about 0.2 degrees of electricity, can be a one-time size of less than 15 mm of poor manganese ore enrichment, improve the manganese crystalline position of 3-18 degrees, a good solution to the poor manganese ores can not be smelted into the furnace of a major problem over the years. The strong magnetic separator is used for magnetic separation and recovery of rare earth ores, which can fully recover and utilize the rare earth tailings that cannot be recovered by disk magnetic separator and shaking table, and the recovery rate can reach more than 95%; it is used for magnetic separation of zircon, rutile and niobium-tantalum ores, and it can achieve the purpose of magnetic separation at one time. This article will introduce a roll-type strong magnetic separator – an accurate and efficient magnetic force- and its tips.

Roll Strong Magnetic Separator Introduction

The roller-type strong magnetic separator is a highly efficient equipment for the separation of weakly magnetic minerals, mainly used for the separation of weakly magnetic minerals and non-magnetic minerals. Its core technology is to use the strong magnetic field and the force of the roller surface to make the magnetic particles adsorbed to the roller surface, while the non-magnetic particles leave with the material flow, thereby achieving the separation of minerals. It is widely used in mineral processing, metal recovery, non-metallic mineral purification, and environmental protection.

Working Principle

The roller-type strong magnetic separator mainly uses the principle of magnetic force to realize the separation of different magnetic minerals through the strong magnetic field generated by the strong magnetic roller. In the working process, the ore is fed into the magnetic separator evenly by the feeder, and after the rotation of the strong magnetic roller, the ore is attracted to the surface of the roller under the action of a strong magnetic force. The minerals with strong magnetism are firmly adsorbed on the roller and move to the concentrate collection area with the rotation of the roller; while the minerals with weak magnetism or non-magnetic minerals are not subjected to sufficiently strong magnetic force and slide down to the tailing area along the side of the roller, thus realizing the effective separation of concentrate and tailing.

Technical Characteristics

• High magnetic field strength: The roller-type strong magnetic separator adopts high-performance magnetic materials and a unique magnetic pole structure, which can generate magnetic field strength up to hundreds or even thousands of gauss, ensuring rapid and accurate mineral separation.
• Simple structure: The whole machine has a simple structure and strong rigidity, which makes it suitable for high-power production in a more severe environment. Meanwhile, it is easy to operate and intuitive to maintain.
• Gradient sorting: The selection of full magnetic rolls for gradient separating improves the recovery rate.
• Wide range of applications: It is suitable for sorting weakly magnetic minerals such as manganese ore and limonite and can also be used to purify fine clay minerals such as kaolin and bauxite, remove fine weakly magnetic staining impurity particles in clay minerals, and in other application scenarios.

Applications

Roll-type strong magnetic separator has a wide range of applications, including but not limited to the following:

• Mineral purification: Used for the purification of fine clay minerals such as kaolin and bauxite.
• Impurity removal: Remove fine weakly magnetically stained impurity particles from clay ores, reduce iron oxide content in quartz sand, feldspar, and barite, and reduce copper content in molybdenum concentrates.
• Coal treatment: Used for coal ash removal and desulfurization.
• Other applications: Improving the quality of apatite, cleaning rare earth minerals, seashore sands, and other useful minerals, continuous removal of abrasive particles in lubricating oil to realize the recovery and recycling of lubricating oil, filtration of chemical, instrumentation, petroleum, and other industries in the recovery of crude liquid and purification of catalysts and other useful substances, as well as for industrial and domestic wastewater purification and so on.

Tips for Maintaining Roller Strong Magnetic Separator

Maintenance

To ensure the normal operation and prolong the service life of the roller-type strong magnetic separator, regular maintenance work is required. Specifically including but not limited to the following aspects:

• Media plate maintenance: The media plate is an important part of the magnetic separator, which needs to be kept unobstructed. It is recommended to clean it every 20 to 30 days and replace it regularly according to the wear and tear of the plate. At the same time, make sure that the gland screws are tightened to ensure the stability of the equipment.
• Temperature rise monitoring: The temperature of the lubricating oil and cooling oil should be closely monitored during the operation of the equipment. Once found abnormal rise should be reported immediately and measures such as shutdown maintenance to prevent overheating damage. At the same time, the temperature rise of the reducer should also be monitored in real time and shut down immediately for inspection when it exceeds the set limit.
• Regular lubricant replacement: Regular lubricant replacement is the key to maintaining equipment lubrication performance. Regular lubricant replacement ensures smooth operation of the equipment and reduces wear and tear.
• Instrumentation check: Regularly check whether the pointers of the oil pressure gauge, water pressure gauge, voltmeter, and ammeter are flexible and whether the readings are accurate. When abnormalities are found, the relevant personnel should be notified in time to deal with them.
• Collaborative work check: Roll-type strong magnetic separators and other equipment are essential to work together. In particular, the pre-treatment equipment such as weak magnetic and slag removal links ensures its normal operation to provide an ideal operating environment for strong magnetic operation. Therefore, it is necessary to pay attention to and ensure that the front and rear equipment are in good operating condition.

Troubleshooting Common Issues

Operation Tips

• Use only manufacturer-recommended parts and consumables.
• Train operators on proper handling and maintenance procedures. Post workers shall not change the excitation current without authorization.
• Keep a maintenance log to track inspections, repairs, and replacements.
• Avoid overloading the separator to prevent mechanical stress.
• Implement a pre-screening system to remove large debris or non-magnetic materials.
• It is strictly prohibited to touch the turntable and magnetic poles with iron or other magnetic conductors during the operation of the main machine.
• Electrical equipment should be kept dry and clean to prevent water from splashing on the electrical equipment.
• Observe whether the pointers of the oil pressure gauge, water pressure gauge, voltmeter, and ammeter are flexible and the readings meet the requirements, and find the relevant personnel to deal with the problems in time.

By following these maintenance, troubleshooting, and operation tips, your strong roller magnetic separator will operate efficiently and reliably, reducing operational costs and maximizing productivity.
