Cyclone separator

A cyclone separator comprising:

• a cylindrical housing;
• a separating wheel disposed in an upper portion of the housing;
• a carrier gas/product inlet connected with an upper portion of the housing such that a carrier gas/mixed size particle flow spirals peripherally and downward through the housing;
• a tubular built-in unit mounted along a central axis of the housing, the built-in unit having a flared lower section configured to draw the carrier gas/mixed size particle flow upward through the built-in unit, the built-in unit having a flared upper end disposed below the separating wheel such that carrier gas and fine particles pass through the separating wheel and are discharged through a fine product discharge outlet defined at an upper end of the housing and larger particles are drawn into the peripheral and downward carrier gas/mixed size particle flow;
• an oversized product discharge opening defined at a bottom end of the housing such that coarse particles in the carrier gas/mixed size particle flow are propelled through the oversized product discharge opening as less coarse and fine particles and carrier gas are drawn into the lower end of the built-in unit.
