Problems solved by technology

In order to increase the processing capacity of the equipment, this type of equipment adopts the method of increasing the width of the swivel, but for the horizontal magnetic field vertical ring high gradient magnetic separator, the width of the swivel is the separation air gap, and increasing the width of the swivel is to increase the separation air gap , the horizontal magnetic field vertical ring high gradient magnetic separator obtained in this way has a large sorting air gap, serious magnetic flux leakage, and large magnetic energy loss, resulting in low background magnetic field strength of the equipment; Significant changes, unable to grade adsorption according to mineral magnetic strength, resulting in low utilization rate of magnetic energy

Abstract

The invention relates to the technical field of magnetic separation equipment, in particular to a horizontal magnetic field type vertical-ring high gradient magnetic separator. The horizontal magneticfield type vertical-ring high gradient magnetic separator comprises a rack, a separation ring, a magnetic system, an exciting coil surrounding the magnetic system, a drive mechanism used for drivingthe separation ring to rotate, a feeding device, a flushing device and a receiving device, wherein separation space is formed in the magnetic system, and the separation ring is arranged in the separation space; a background magnetic field with magnetic field intensity uniformly distributed in the direction of separation height is formed in the separation space by cooperation of the exciting coil and the magnetic system, the separation ring rotates to pass the separation space to change magnetic field distribution of the separation space, and an induced magnetic field in horizontal magnetic field direction and with the magnetic field intensity changing in the direction of separation height is formed in the separation space. By designing the separation ring structure under the condition thatpower consumption is not added, high-low collocation of the magnetic field intensity in the direction of separation height is formed, the separation effect is improved, the magnetic energy use ratiois increased, magnetic medium blockage caused by magnetization agglomeration of magnetic minerals is reduced, and follow-up back flush unloading work is facilitated.

Description

technical field [0001] The present invention relates to the technical field of magnetic separation equipment, more specifically, to a horizontal magnetic field vertical ring high gradient magnetic separator. Background technique [0002] The development of high gradient magnetic separator has gone through three stages: periodic high gradient magnetic separator - continuous flat ring high gradient magnetic separator - continuous vertical ring high gradient magnetic separator, among which continuous vertical ring high gradient magnetic separator Due to the outstanding advantages of continuous operation, large equipment processing capacity, and not easy to block the medium, it is widely used in major mines at home and abroad. Continuous vertical ring high gradient magnetic separator can be divided into vertical magnetic field vertical ring high gradient magnetic separator and horizontal magnetic field vertical ring high gradient magnetic separator according to the direction of ...
