How many types of ball mill feeder?

The feeder type ball mill

1, chute feed

The material is passed through the tube (or feed hopper) into the conical sleeve located inside the hollow shaft of the ball mill. Cross section of the chute is oval.

2, drum feeder

Only for the position of the feeding position higher than the ball mill axis. Generally used for open circuit grinding system, products will be broken into ball mill grinding.

3, screw feeder

The working principle of the spiral to the feeder with the drum feeder is the same, but the structure is not the same. Its working principle is: the material from the feed hopper into the rotary wheel, the wheel will raise up the material, then the blade poured directly on the spiral sleeve is located inside the hollow shaft, spiral vanes in the delivery of materials to the ball mill.

4, spiral feeder

Spiral feeder and a spiral spoon, when rotating the material along the inner wall of the sliding bottom gradually to the spoon. The side wall at the bottom of the spoon is provided with a round hole which is aligned with the hole of the hollow shaft neck of the ball mill.

5, United feeder

Coarse grain feeding can cover the hole directly by the spiral separator and enhance into hollow shaft neck, and in the trough of return sand (coarse classification after) by the hook head and cut up by helical baffles cylinder into the hollow shaft. In this way not only to improve the production capacity of the feeder, and coarse material (broken products) do not need to dig up the spoon by spoon, thereby reducing the abrasion. Combined feeder suitable for closed-circuit grinding process.
