Dissecting microscope is used either for dissecting the material or for less magnifications, i.e., only 6X, 12X or rarely 20X. It is mainly used for embryo separation, taxonomic studies, etc. A dissecting microscope (Fig. 3) consists of a basal foot and a limb. The ‘stage’, made up of a simple glass plate, is attached to the limb.

Industrial Ball Mills: Steel Ball Mills and Lined Ball Mills
Steel Ball Mills & Lined Ball Mills. Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800’s. The basic construction of a ball mill is a cylindrical container with journals at its axis. The cylinder is filled with grinding media (ceramic or metallic balls or rods

Ball mill media optimization
mill grinding rate over the material’s grindability as measured in the lab. Mill percent solids optimization has thusly been achieved (McIvor et al., 2000). For media sizing, maximizing the mill grinding rate on a given ore is equivalent to maximizing the mill grinding efficiency. Ores of different grindability will be part of the discussion.

Ball Mills
Planetary ball mills are the most popular mills used in scientific research for synthesizing MgH 2 nanopowders. In this type of mill, the ball-milling media have considerably high energy, because milling stock and balls come off the inner wall of the vial and the effective centrifugal force reaches up to 20 times gravitational acceleration.
