1. Precautions for the use of ball mill combined feeder
a. Regularly check the wear of the spoon head and replace it in time.
b. Regularly check the wear of the feeder frame. If there is slurry leakage, it needs to be replaced with a new feeder in time.
2. The following are four types of commonly used ball mill feeders:
a. The feeding hopper of the slide pipe enters the conical sleeve located in the hollow journal of the mill, and slides into the mill along the rotating cylinder wall. The section of the slide pipe is oval.
b. Snail-shaped feeder The snail-shaped feeder has a spiral spoon, which makes the material gradually slide to the bottom of the spoon along the inner wall of the spoon when rotating. There is a round hole on the side wall at the bottom of the spoon, which is aligned with the hole of the hollow journal of the ball mill, and the material enters the ball mill through the round hole on the side wall and the hollow journal.
c. Screw feeder The working principle of the screw feeder is the same as that of the drum feeder, but the structure is different. The material is fed into the scoop wheel from the feeding funnel, and the rotating scoop wheel lifts the material up, and then is poured directly into the spiral sleeve located in the hollow shaft by the vane, and the inner spiral blade transports the material into the mill.
d. The coarse-grained feed of the combined feeder can be directly lifted by the spiral partition through the hole of the cover and sent into the hollow journal, and the returned sand in the trough is picked up by the spoon and hook and passed through the spiral of the cylinder. The partition is fed into the hollow journal. This method not only increases the output of the feeder, but also the coarse-grained materials do not need to be picked up by the spoon, thereby reducing the wear of the spoon.
