Finishing mills roll cold coils of pickled hot-rolled sheet to make the steel thinner, smoother, and stronger, by applying pressure, rather than heat. HOW. Stands of rolls in a cold-reduction mill are set very close together and press sheet of steel from one-quarter inch thick into less than an eighth of an inch, while more than doubling its length

Highlights Operational grinding parameters have marginal effect on fineness of particle. Real surface area enhancement did not occur on the external surfaces, but in the inner surfaces due to lime hydration process conditions. The ball mill load and speed are the most important parameters rather than material charged volume. The undersize percentages of 297, 53 and 10 μm are quality control ...

However ball mills are relatively expensive and a lime demand of 20 000 kg/d is required before ball mill reactors should be considered. When the demand is less than 20 000 kg/d, a small size grade quicklime, such as the -10 mesh quicklime examined in the experi- mental phase of the study, should be used with a stirred tank reactor.

which can grind efficiently in a mill, c is the exponent which characterizes the ball size distribution. The condition for efficient grinding, defined by Eq. 7, will be fulfilled when the grain size distribution and the ball size distribution are the same, which means that the parameters of both distributions are equal in Eqs. 7 and 9: m c.

For example, ball mills use large media, normally 1/2” or larger, and run at a low (10-50) rpm. The other mills, such as sand, bead, and horizontal, use smaller media from 0.3mm to 2mm, but run at a very high rpm (roughly 800-1200). High speed dispersers with no media run even faster rpm (1200-1800).
