Air separator consists of a cylindrical vessel tapered at the base (see Figure 1). A central shaft with rotating disc and blades is present at the centre of the vessel which is rotated by means of a motor. The equipment also consists of a set of fan blades to produce a current of air. Feed is introduced into the vessel by means of feed inlet ...
