BF type beneficiation flotation machine product introduction

BF type flotation machine is a new generation of flotation machine equipment improved and upgraded on the basis of SF type flotation machine. It is a self-aspirating flotation machine with novel structure. In addition to the advantages of horizontal configuration, midore foam self-return, self-aspirating air, etc., it also has low power consumption, large intake capacity, low impeller line speed, long service cycle of wear parts, and stable mineral liquid level.

Outstanding advantage

1, large suction capacity, low power consumption; The pulp surface is equipped with automatic control and electric control device, easy to adjust;

2, the impeller is composed of a closed double-truncated cone, which can produce a strong slurry circulation;

3, each tank has the triple function of suction, suction and flotation, its own flotation circuit, does not need any auxiliary equipment, horizontal configuration, easy to change the process;

4, pulp circulation is reasonable, can reduce coarse sand precipitation. The slurry in the tank has a lower circulation, which is conducive to the suspension recovery of coarse minerals.

Working principle

When the main shaft is driven by the motor to drive the impeller to rotate, the pulp in the impeller cavity is thrown out to the four sides by the centrifugal force, so that the negative pressure is generated in the impeller cavity, and the air is inhaled through the suction tube. At the same time, the pulp under the impeller is sucked through the center hole of the lower cone of the impeller, mixed with air in the impeller cavity, and then thrown around through the channel between the cover blades. The air and part of the pulp move to the upper part of the flotation tank to produce foam, and enter the next tank by overflow, while the other part of the pulp moves to the bottom of the flotation tank and enters the impeller cavity again by the suction of the impeller. Forming the lower circulation of the pulp. The existence of subpulp circulation in the flotation machine is conducive to the suspension of coarse minerals and can reduce the deposition of coarse sand at the bottom of the tank.
