CLF type coarse and heavy particle flotation machine

The impeller of the CLF type flotation machine adopts a high specific rotation number backward-inclined blade impeller. The shape of the lower blade is designed to be consistent with the streamline of the slurry passing through the impeller blades. The stirring force is weak. At a low impeller speed, the slurry is ensured to circulate internally along the prescribed channel. The upper slurry flows downward to the lower part of the false bottom through the circulation channel. The pressure difference generated in the aeration zone and the non-aeration zone and the impeller It enters the impeller area under the action of suction force, and then passes through the grid plate to form a suspended layer above the grid plate. Coarse-grained minerals can be suspended above the grid plate. The grid plate makes the mineralized bubbles of coarse-grained minerals rise short, so that the coarse-grained minerals are in a shallow tank flotation state, and reduce the turbulence of the slurry in the upper area of the tank, establishing a stable separation zone and foam layer.

Huston Mining provided a mining industry-wide service project for a barite concentrator. After testing, Huston customized a gravity separation-flotation combined process for it. For the flotation part, Huston uses a CLF type coarse particle flotation machine. The main features of this flotation machine are the high density of flotation slurry and high selection concentration, which can effectively improve the recovery rate of coarse and heavy minerals.
