They extend to almost the full length of the shell and occupy about 35% of the shell volume. In such mills, attrition forces predominate but impacts also play a part in size reduction. They are classed as intermediate grinders and are more useful than ball mills for milling sticky materials. Selection Criteria for Sizereduction Equipment

Ball milling: Pieces of lead are put into a rotary mechanical mill, forming fine lead flakes, which are then oxidised in air and removed. This also gives 75 – 80% lead oxide. Red lead (Pb 3 O 4) can also be added to the PbO formed by these methods, as it is more conductive. This

Optimization of Firing Temperature for Hematite Pellets

Iron ore fines and limestone of –10 mm size and coke breeze of –6 mm size were ground separately in laboratory ball mill. Green pellet mixes for different level coke breeze were prepared by mixing the iron ore fines, limestone, and bentonite and coke breeze as per Table 2. Green pellets were prepared using laboratory scale balling disc.

Multiple Choice Questions on Mechanical Operations

1. Size enlargement (opposite of size reduction) is not a mechanical operation. 2. Wear and tear in wet crushing is more than that in dry crushing of materials. 3. A ''dust catcher'' is simply an enlargement in a pipeline which permits the solids to settle down due to reduction in velocity of the dust laden gas. 4.
