Difference between Dry Ball Mill and Wet Ball Mill

The differences between wet ball mill and dry ball mill are mainly reflected in two aspects:

 

Different Working principles between Dry and Wet Ball Mills

When the dry-type ball mill is running, the materials enter the first chamber of the mill evenly by the feeding device through the feeding hollow shaft screw. The chamber is equipped with step lining plate or corrugated lining plate, equipped with steel balls of different specifications. The centrifugal force generated by the rotation of the ball mill barrel brings the steel ball to a certain height and then falls down, thus crushing and grinding the material.

 

After coarse grinding in the first bin, the material enters the second bin through a single-layer partition board. The bin is equipped with a flat lining board and equipped with steel balls of different specifications to further grind the material. Finally, the qualified materials are discharged through the discharge grate to complete the grinding operation.

 

 

Different Structure between Dry and Wet Ball Mills

Both the dry ball mill and the wet ball mill include the feeding part, the discharging part, the rotating part, the transmission part (reducer, small transmission gear, motor, electric control) and other main parts.

 

The difference is that the structure of the dry ball mill is more complex than that of the wet ball mill, and its discharge port is in the shape of a straight cylinder. At the same time, it is equipped with an induced draft device, a dust discharge pipe and a dust remover, which is also determined by its working principle. The structure of the wet ball mill is simple, without adding too many auxiliary accessories. The discharge port is in the shape of a trumpet, with a built-in screw device to facilitate discharge.
