Thickener mechanism WARMAN EQUIPMENT

A thickener mechanism for a settling tank is provided in which separate rake arms with scraper blades sweep an outer and an inner annular area respectively of the tank. Connected with the rake arms for the outer annular area are cone scraper blades which keep the underflow solids in the centre of the tank in motion for ease of withdrawal.
