Cyclones have been regarded as one of the simplest and cheapest type of separator on account of their high efficiency, adaptability, and relative economy in power. Cyclones have been widely used in different industrial processes. The literature reveals that the cyclone efficiency is dependent on the particle size from the mass of the mixtures heterogeneous
