CaCO 3 micron size powder, supplied by Adacal Mineraller LTD, was used as starting material. The morphology of this powder is shown in Fig. raw CaCO 3 particles are micron size and irregular in shape. CaCO 3 powder underwent HEBM in a planetary ball mill (Retsch PM 100, Germany) using container and balls (10 mm diameter) made from chromium hardened steel.

The results of ball mill grinding tests are shown in Figure 6. Figure 6a,d show the effect of grinding time on the particle size composition of the raw ore and pebbles, respectively. As expected, the grindability of the raw ore was stronger than that of the pebbles in the ball mill, although this distinction was less obvious as in the abrasion ...

In this work, a planetary ball milling was used to modify the surface properties of calcitebased material from waste oyster shell under the rotational speed of 200600 rpm, grinding time of 5180 min and sample mass of 110 g. The milling significantly changed the microstructural properties of the calcitebased minerals (, surface area, pore volume, true density, and porosity). The ...

1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.
