subject: Hematite Beneficiation Method And Equipment [print this page] Hematite flotation separator structure features:
Mining and Metallurgical Research Institute, Beijing, China SF hematite beneficiation equipment, flotation machine structure, mainly consist of the motor, suction tube, central tube, tank, impeller, main shaft, cover , bearing body components, the effective volume is greater than 10 rFi3 tank additional draft tube, the false bottom and the adjustment ring.
Working principle:
The impeller is mounted in the bottom of the spindle, through a pulley installed on the upper end of the spindle motor drive shaft and the impeller rotation. The air is inhaled by the suction pipe. Impeller equipped with a cover at the top and the center tube.
Hematite beneficiation equipment, flotation machine, the motor drives the impeller high-speed rotating impeller on the leaves and cover the pulp from between the blades on the impeller throws a certain amount of negative pressure between the impeller and cover. The role of the differential pressure air through the inspiratory tube automatic suction tube from the center of mine and to the mining suction tube pulp. Pulp and air between the impeller and cover form the swirling to further refine bubbles, and through cover to become the steady flow into the entire trough; and because the impeller blade force to promote the lower part of the slurry circulation to prevent coarse particles mineral precipitation phenomenon occurs in the trough .
Beneficiation equipment, flotation equipment, include flotation machine and ancillary equipment (stirred tank, dosing, etc.). In general, flotation machines are mostly standard equipment. Flotation aids mostle belong to the non-standard equipment. Flotation machine equipment to complete the flotation process, its working principle roughly can be divided into the mixing zone, the separation zone and bubble zone. Which the separation zone mineral particles attached to the bubbles, the formation of mineralized bubbles off put.
SF flotation machine's main features include: (1) backward curved blade impeller, causing the tank slurry up and down cycle to prevent the precipitation of coarse-grained minerals, coarse flotation; (2) The line speed of the impeller relatively low, long life wearing parts; (3) the power consumption per unit of volume of 10% to 15% lower than the same type of flotation machine, inspiratory capacity increased by 40% to 60%.
