Automatic magnetic levitation concentrator .This series of products aim at the purification of strong magnetic minerals whose specific magnetization coefficient is more than 3000 *10-6 cm/g, or the reduction of coarse grinding particle size to improve production efficiency on the premise of guaranteeing the grade of the original concentrate. It has the characteristics of improving silicon content, simplifying process, saving water and energy, fully automatic control, etc. The field effect is good.
Working Principle: The automatic magnetic suspension concentrator mainly consists of feeding pipe, overflow trough, separating cylinder, feeding valve, discharging valve, control cabinet, etc.
After the pulp is fed into the ore trough from the upper part, the pulp enters the magnetic field area in the middle and upper part of the central tube. Under the action of fixed magnetic field, moving magnetic field and auxiliary magnetic field, the magnetic minerals suspend in the form of a magnetic chain, while the non-magnetic minerals such as gangue will keep their original gravity because they are not affected by the magnetic force. At this time, the upward water opposite to the direction of mineral settlement is given, when the non-magnetic minerals are subjected to settlement. When the force is less than the hydraulic force, the non-magnetic minerals will rise and overflow from the upper part of the equipment. When the sedimentation force of the minerals is greater than the hydraulic force, the minerals will sink, and the minerals will be discharged from the lower outlet of the separation equipment, thus realizing the separation of minerals. It should be noted that in other magnetic gravity separation, magnetic minerals sink in the form of aggregates, while in magnetic levitation concentrator, they sink in the form of vertical magnetic links.
Changsheng fully automatic magnetic suspension concentrator is a new magnetic gravity separation equipment which combines the best advanced technology and can produce higher grade concentrate. Its revolutionary innovation makes it superior to other similar products - feldspar beneficiation in improving product grade, ensuring the stability of beneficiation index and controlling tailings grade. Compared with traditional equipment, the concentrate produced by automatic magnetic levitation concentrator is of higher grade. Through the control of intelligent control system, a special background magnetic field distribution is formed in the selected area. Under this special background magnetic field, ore particles complete a special dynamic separation process. When ore particles are fed into the ore, they are pre-adjusted in the narrow space where the magnetic field exists to prepare for the formal separation. When entering the beneficiation area, the magnetic minerals, poor conjoints and gangue in the minerals are decomposed by secondary magnetic gravity separation. After separation, the grade of the concentrate is effectively improved and the phenomenon of black running is avoided. The concentrate index after separation is more stable. The principle of reverse magnetic field to disperse minerals is more water-saving and more controllable than the traditional equipment to disperse minerals by backwash water. X-ray beneficiation.
Compared with the traditional equipment, the automatic magnetic levitation concentrator has a larger capacity, up to 75 t/h. From the outside, the automatic magnetic levitation separator is just like the traditional magnetic column. In traditional equipment, due to the physical law of the circular excitation source, the radial magnetic field in the separator decays rapidly, and the farther the distance is, the worse the effect is, the field strength in the center of the column will be very low and the phenomenon of void will be formed, and there is almost no magnetic separation effect. The bigger the cylinder of the selected area is, the more serious this phenomenon is. This is also the key technical bottleneck that this kind of equipment can not realize large-scale and industrialization at present. Fully automatic magnetic levitation concentrator uses special magnetic field design concept and unique mechanical structure to realize the large-scale equipment, improve the processing capacity of single machine, effectively apply to the purification of strong magnetic minerals, and also reduce the size of coarse grinding on the premise of guaranteeing the grade of the original concentrate, improve production efficiency. It has the characteristics of improving the product, reducing silicon, simplifying process, saving water and energy, and fully automatic control. The field application proves that the effect is good.
