Dry magnetic separator for improving magnetic separation and material distribution efficiency

Technical Field

The invention relates to the technical field of mining mechanical equipment, in particular to a dry magnetic separator for improving magnetic separation and material distribution efficiency.

Background

The dry magnetic separator is used for separating magnetic mineral aggregate from non-magnetic mineral aggregate, and when the magnetic separator is used, the mineral aggregate is required to be kept dry, and mineral aggregate particles can freely move.

The existing dry magnetic separator conveys mineral aggregates to a rotary material separating barrel from a feeding hole, wherein a magnetic system is fixedly sleeved in the material separating barrel, so that the magnetic mineral aggregates in the mineral aggregates are attracted by the magnetic force of the magnetic system and are adsorbed on the rotary material separating barrel, and the residual non-magnetic mineral aggregates fall into a tailing material opening under the influence of the centrifugal force and the self gravity of the material separating barrel, and then the magnetic mineral aggregates rotate along with the material separating barrel until the material separating barrel rotates to a position separated from the magnetic system, so that the mineral aggregates are subjected to the self gravity action and fall into the mineral concentrate material opening, thereby realizing mineral aggregate separation, but in the operation, as the mineral aggregates fall onto the material separating barrel, the mineral aggregates are easy to stack, so that part of the magnetic mineral aggregates are stacked on the non-magnetic mineral aggregates, the magnetic force on the mineral aggregates is weakened, and the mineral aggregates are not adsorbed on the material separating barrel in the subsequent process, but directly fall into the tailing port, lead to the tailing to need carry out the secondary and select separately, and then influence magnetic separation and divide material efficiency.
