Fine grain dry separator for weakening magnetic effect loss

Abstract

The invention discloses a fine grain dry separator for weakening magnetic effect loss and belongs to the technical field of magnetic ore separating machines. The fine grain dry separator comprises a lower box, a rack, an upper box, a permanent magnet barrel, a speed reducer, a motor, an ore discharging adjusting device, a gear, a base, an adjusting plate support and the like. The lower box is fixed to the rack through bolts. An axle bed of the permanent magnet barrel is arranged on the rack and connected to the rack through bolts. The permanent magnet barrel is arranged in the upper box and the lower box. A connecting position of the upper box and the lower box is sealed through soft rubber, and connection is achieved through bolts. The surfaces of contact between the permanent magnet barrel and the upper box and the lower box adopt sealing materials for sealing. One end of the ore discharging adjusting device is inserted into an internal seat of the lower box, and the other end of theore discharging adjusting device is arranged outside a lower box body to be connected with an adjusting handle. The permanent magnet barrel is connected with the speed reducer through the gear, and the speed reducer is connected with the motor through a coupler. The fine grain dry separator provided by the invention is simple in structure and convenient to maintain and repair, energy is saved, the service life of equipment is prolonged, and power loss caused by magnetic effect is reduced.

Description

technical field [0001] The invention relates to a fine-grain dry separator that weakens magnetic effect loss in the technical field of magnetic mineral separation machinery, and is particularly suitable for the separation or separation of fine-grain magnetic materials with high cylinder rotating speeds. Background technique [0002] At present, in recent years, with the continuous development of mineral resources, high-grade mineral resources have been gradually exhausted, and the development and utilization of resources have gradually turned to low-grade lean ore. Due to the restriction of technical level and the disadvantage of iron ore resource conditions, the cost of developing and utilizing lean iron ore resources is relatively high. "More crushing, less grinding, and early tailing" has become an effective way to reduce costs and increase efficiency for new concentrators. With the continuous enrichment of crushing means and the finer particle size of crushing, the appl...

Problems solved by technology

[0003] However, because the cylinder of the fine-grained dry separator is mostly made of thin stainless steel plates, the cylinder cuts the magnetic force lines while running at high speed, which is equivalent to the current generated by the conductor cutting the magnetic field, causing the cylinder to generate double eddy current and other magnetic effect losses, with direct consequences. The tube skin heats up rapidly, the magnetic loss power increases, and the magnetic performance of the magnetic system decays faster, so it cannot be discarded more efficiently

Due to the shorter attenuation period of the magnetic properties of the magnetic system, frequent replacement of equipment is required, affecting normal production and causing economic losses
