Crushing And Screening Dry Circuit

(PDF) Crushing and Screening Handbook

Removal of unwanted minerals is done dry. Most of the production is delivered as Altafloat with a particle size defined by d s 500 99.9 mm and d s 74 mm. This requires a comminution circuit which does not produce excess fines. Originally, roller crushers in closed 8 circuit with screens were used for this purpose.
