continuous ball mills. In an experiment conducted using a wet laboratory continuous ball mill filled with pebbles, cylinders and balls of equivalent volume and a 95% calcite feed combined with a 5% quartz, ball load, density and shape were varied. It was shown that decreasing the ball load by by weight also decreased the residence time by 40%.

These calcite blocks with different roughness will be used in the test of surface wettability and surface energy. The calcite samples used for grinding and flotation was crushed to about 2 mm, and then ground by a ball mill and a rod mill respectively. The ground products were screened and classified using the Taylor standard sieve.

Most of the grinding plants for calcite are equipped according to the setups of tumbling mills such as ball mills. However, it would be much more logical to replace such plants using ball mills for calcites with types of equipment based on vertical mills characterized by lower energy consumption and higher capacity.

Ball Mill with Classifying System. Ball mill is also known as rotary ball mill. Inside the ball mill, there are many different sizes of balls, which is called ball media. And when the ball mill rotates, the ball media and feed limestone inside the ball mill will collide and crush so as to make fine and ultra fine calcium carbonate powder.
