DESIGN AND FABRICATION OF MINI BALL MILL.
This project is to design and fabricate the mini ball mill that can grind the solid state of various type of materials into nano-powder. The cylindrical jar is used as a mill that would rotate the material that about to be ground, a motor is used to power the system so that the jar can rotate in high speed and using the regulator controls the speed of the rotation of the jar.

How Slurry Transport inside a Tumbling Grinding Mills
The transport of slurry through the ball-bed in tumbling mills depends on the distribution of voids inside the charge and the speed of the mill. When balls of different sizes are present in the mill, then there is a tendency for the balls to move at different speeds along the axial direction. Ideally, balls would not move in the axial direction ...

Tumbling Mill Working Capacity Influencing Factors
Tumbling mill is also known as a ball mill or rod mill. They are all composed of a cylindrical cylinder lying horizontally on the bearing, and the material is ground into powder by rotating the cylinder. When we want to discuss the factors that affect the tumbling mill working capacity, we must first know the working principle of the tumbling mill.
