Abstract
LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA SECADO DE AGLOMERADOS Y POLVOS DE POLIMERO, EN PARTICULAR DE POLICARBONATO AROMATICO TERMOPLASTICO U OTROS POLIMEROS TERMOPLASTICOS, COMO POR EJEMPLO COPOLIMERO ACRILNITRILO-BUTADIENO-ESTIROL, EN UNA COLADA, DONDE SE DISPONE EL AGLOMERADO O EL POLVO DE POLIMERO TERMOPLASTICO CONTENIDO EN AGUA, DISOLVENTE O EN AMBOS, EN UN APARATO PREVISTO CON COMPONENTES ROTATIVOS PARA LA LIMPIEZA DE LAS PAREDES DEL APARATO, ASI COMO DISTRIBUCION Y TRANSPORTE DEL MATERIAL DE SECADO MEDIANTE AFLUENCIA TERMICA A TRAVES DE LAS PAREDES O POR MEDIO DE LOS COMPONENTES ROTATIVOS O BIEN A TRAVES DE AMBOS, SIENDO APLICADA UNA DISPOSICION DE CORTE BAJO LA DISPOSICION DE LA COLADA EN EL DISOLVENTE CONTENIDO O EN LA HUMEDAD PRESENTE. PARA ELLO SE COMBINA EL PROCESO DE SECADO Y LA GRANULACION DE LA COLADA QUE TIENE LUGAR A CONTINUACION.
