Mineral Processing Introduction

They are most commonly employed in closed circuit within grinding circuits and are used to return coarse material back to the ball or rod mill for further grinding. The main advantages of cyclones is that they have large capacities relative to their size and can separate at finer sizes than most other screening and classification equipment.
