The invention relates to the technical field of material separation, and discloses mineral separation equipment based on a composite magnetic field. The mineral separation equipment based on the composite magnetic field comprises a spiral chute and a magnetic system, wherein at least a part of the magnetic system is located below a part of the spiral chute; and the magnetic field intensity acting on the spiral chute, of the magnetic system, is gradually weakened from the inner side of the spiral chute to the outer side of the spiral chute. According to the mineral separation equipment based on the composite magnetic field, the magnetic system is applied into the spiral chute, and when materials to be separated are subjected to moving separation in the extension direction of the spiral chute, a magnetic field force generated by the magnetic system acts on the materials to be separated and located in the spiral chute; when the materials to be separated pass through a magnetic field area formed by the magnetic system, magnetic particles or weakly-magnetic particles are stressed by an overall inward magnetic force, and the distribution area of the magnetic particles or the weakly-magnetic particles is closer to the inner side of the spiral chute, so that the zonal distribution trend of the magnetic particles or the weakly-magnetic particles and gangue particles along the chute surface of the spiral chute is reinforced, and the recovery rate for the magnetic particles or the weakly-magnetic particles in concentrates is increased.
Description
technical field [0001] The present disclosure relates to the technical field of material separation, in particular to a mineral separation device based on a composite magnetic field. Background technique [0002] Spiral chute is a kind of flow film separation equipment, which is often used in mineral processing plants to separate fine-grained metal ore. The cross-sectional flow field of the spiral chute has a circulating flow from the upper layer outward and the bottom layer inward. The flow field of the selected metal ore fine particles in the equipment is mainly affected by gravity, buoyancy, centrifugal force, friction, fluid resistance and equipment wall support force. It is generally believed that the feed particles first complete the longitudinal stratification. During this process, the coarse and heavy particles tend to be distributed in the lower layer, while the light and fine particles are mainly distributed in the upper layer; The friction force is small, and it ...
