Working principle
This machine is a horizontal cylindrical rotating device, driven by external gears, sprockets or belts, and a two compartment grid type ball hemp machine.
The material is uniformly fed into the ball mill bin through the feeding machine and the hollow shaft screw, which contains three different specifications of ball media. The rotation of the cylinder generates centrifugal force, which brings the ball media to a certain height and then falls down, causing heavy impact and grinding on the material. After the material reaches rough grinding in the warehouse, it enters the second warehouse through a single-layer partition plate, which contains four different specifications of ball media for further grinding. The powdered material is discharged through the discharge port screen and enters the vibrating screen powder machine for classification and grinding operation.
Structural characteristics
This machine consists of a feeder, a discharge section, a rotating section, a transmission section, and a grading section. The hollow shaft is made of castings, and the inner lining can be made according to user requirements. The equipment runs smoothly and reliably.
