When the magnetic mineral processing device is used, after materials are crushed, the crushed final granularity reaches-15 mm and accounts for more than 85%, after the materials are fed through the feeding device, the materials are conveyed on the belt at a certain speed and pass through the magnetic drum, the nonmagnetic gangue minerals 15 fall down in the direction of C shown in figure 1 under the action of the belt speed and gravity, and slide down along the right side of the second side plate 12 to enter the nonmagnetic product collecting bin 13; the magnetic separation mineral 16 is adhered to the belt under the magnetic roller in the direction D shown in figure 1 due to the action of magnetic force, and automatically falls into the magnetic product collection bin 4 due to the disappearance of the magnetic force, so that the effective separation of the magnetic mineral and the non-magnetic mineral is realized.
The purpose of dividing the sector magnetic system into two parts is as follows: when the magnetic separation mineral passes through the front section of the first magnetic system (rough separation), the resultant force of the magnetic force and the gravity of the magnetic mineral is larger than the forward inertia force of the magnetic separation mineral and the interference force of the non-magnetic mineral thrown out due to the belt speed, the magnetic separation mineral is basically adhered to the belt, and when the magnetic separation mineral passes through the rear section of the first magnetic system, the magnetic separation mineral is mainly under the action of the magnetic force and can not fall off along with the non-magnetic mineral by overcoming the resultant force formed by the forward inertia force, the gravity and the interference force of the non-magnetic mineral thrown out due to the belt speed. Therefore, the magnetic induction intensity of the second magnetic system (concentration) is improved to 4500GS, which is increased by 1300GS compared with the magnetic induction intensity of the first magnetic system, thereby realizing the purpose of concentrating and recycling magnetic separation minerals.
