Industrial Plant Flotation Machines in Banks

The dynamic aspect refers to the fluid motions involved and for mixers and flotation cells more specifically to the impeller speeds and energy inputs. It is here that complications arise. For relatively simple mixing problems, as in conditioners, where it has been established that power intensity is a scale-up factor, it can be shown that for contant Power Number and constant power intensity ...
