When the static ball charge level has risen by 300 mm (1 foot), it is an indication of a worn screw liner and a liner inspection/change is recommended. This is applicable only for mills operated with a constant power draw. After any liner change, a new initial ball charge should be measured/recorded, followed by a repeat of the above …

The liver and kidneys are extremely sensitive to cadmium's toxic effects. This may be due to the ability of these tissues to synthesize metallothioneins (MT), which are Cd-inducible proteins that protect the cell by tightly binding the toxic cadmium ions. The oxidative stress induced by this xenobiotic may be one of the mechanisms responsible ...
