Talc grinding in an opposed air jet mill start‐up

We present a study of talc grinding in an Alpine 100 AEG opposed air jet mill with an inline laser granulometer. The conditions for steady state operation have been determined from continuous grinding experiments and show that overloading occurs above a critical value of feed rate classifier resulting in unstable product size distribution. For each rotation speed of the classifier, there is an

The processing of talc depends on the type of deposit. Commonly, the first step is selective mining, followed by floatation to separate the talc from other minerals (eg, silicates and carbonates such as magnesite). Finally, the higher grades of talc are subjected to highly developed beneficiation processes (eg, fine grinding, air classification).
