Some recent grinding installations in Australia have demonstrated potential for ultra-fine grinding with acceptable power consumption (Johnson, 1998). A combination of high-pressure rolls and ultra-fine grinding devices could potentially save energy in the production of ultra-fine particles because they create micro-cracks during the crushing step.

What is the simple distillation? La simple distillation (or distillation simple) is a separation technique used in chemistry laboratories to purify liquids through the removal of impurities non-volatile.It is also used for the separation of mixtures of liquids miscible that differ in p. e. in at least 25 ° C, and it also must present p. e.. The process is governed by the law of Raoult.
