Solid Bowl Centrifuges
Solid Bowl Centrifuges are centrifuges are used in technical processes for the mechanical separation of mixtures of solids and liquids. Sedimentation, centrifugation, and filtration are mechanical separation processes, in contrast to distillation, incineration and thermal drying, which are thermal separation processes. In many processes, mechanical separation is primarily responsible for product quality, production efficiency and environmental control. Mechanical separation processes are found in practically all industrial sectors, including food, chemi- cal, pharmaceutical, biotech, mineral, and environmental.
Advantages
Modern centrifuges have many advantages in comparison to other separation processes such as filtration and sedimentation. Compact designs, sealed construction to control odor emissions and avoid contamination of the product, ease of operation with continuous or automatic control systems, and limited replaceable operating parts such as filter media or filter aids make centrifuges advantageous to use.
Applications
Clarification of liquids Dewatering of sludges and suspensions Thickening of slurries Separation of three-phase mixtures, i.e. two immiscible liquid phases and a solid phase Classification of solids in a suspension according to particle size (wet classification) Sorting of solids by density.
