The weight ratio of the balls with 10 mm and 6 mm diameters was 5:3. The jar was rotated at a velocity of 30 Hz (387 rpm) with one rotation direction. The ball milling was carried out for 0.5, 1.0, 1.5, 2.0, and 3.0 h at room temperature in order to investigate the effect of ball milling time on the production of CNF.

A ball mill rotates its long shaft, and drive a jar which is placed on it. The friction of the rubber surface of the shaft can rotate the jar. The grinding beads (grinding balls) in the jar will constantly hit the sample due to gravity and mechanical force. After a long period of rotation and impact, the sample gradually changes from large pieces to small pieces, and small pieces …

GSI's ball mills are housed with oversized roller bearings and a complete drive system discharging mesh sizes from ~40M to <200M. The capacity, or throughput, of our GSI ball mills are directly linked to the particle size of the ball mill discharge. For instance, it is roughly 3 times as fast to reach a 65 mesh grind than a 200 mesh grind.

clinker into a powder. A ball mill is a large cylindrical tube partially filled with steel balls. The ends of the steel cylinder are attached to trunnions that are supported on journal bearings. As the ball mill rotates, the steel balls in the cylinder rise up on the mill's inside surface and eventually tumble down to the bottom.

The final stages of comminution are performed in tumbling mills using steel balls as the grinding medium and so designated "ball mills.". Since balls have a greater surface area per unit weight than rods, they are better suited for fine finishing. The term ball mill is restricted to those having a length to diameter ratio of 1.5 to 1 and less.

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
