The decanter centrifuges are used for separating two or more different specific weight phases, that is to say, in clarification processes having solid materials in suspension. The separation of the solid from the liquid phase is done inside a cylindrical/ conical rolling drum. The heavier solid phase, settles on the internal walls of the drum, being scraped successively by the inner cochlea until it is expelled thought the orifices located al the end of the conical section. Polymers, selected depending on the process type to be done, are often used to facilitate the addition of the solid, especially in the purification phase. This procedure cannot be applied in intermediate transformation or in the food processes. In this type of centrifuges the suspension feeding to be treated and the discharge, liquid or dehydrated solid, are done in continuous and automatically, thus the presence of operators is not required. Therefore, the decanting centrifuge is the best alternative to other systems of dehydration like Filter Presses and Filters Bands Besides the decanting centrifuges have the below stated advantages: Work in continuous No odour emission High reliability and high safety Low control cost thanks to is automatic functioning Reduced size Good maintenance intervals
