Abstract

SE PRESENTA UN APARATO PARA DESHIDRATAR SUSPENSIONES DE MATERIALES DURANTE SU PASO ENTRE DOS RODILLOS PRENSADORES (10), EN DONDE EL LIQUIDO ES PRENSADO MEDIANTE SOBREPRESION A TRAVES DE LAS SUPERFICIES DE CUBIERTA DE LOS RODILLOS Y LA DESHIDRATACION FINAL TIENE LUGAR MEDIANTE EL PRENSADO EN EL ESTRECHAMIENTO (11) ENTRE LOS RODILLOS (10). LA PARTE SUPERIOR DE LOS RODILLOS (10) ESTA RODEADA POR UNA CARCASA (12) CON ENTRADAS (14) PARA LA SUSPENSION. UNA SALIDA PARA EL MATERIAL SE SITUA POR DEBAJO DEL ESTRECHAMIENTO (11) Y UNAS PALAS LIMPIADORAS (16) ESTAN CONECTADAS CON AMBOS RODILLOS (10) POR DEBAJO DEL ESTRECHAMIENTO (11). LA TRANSFERENCIA DEL MATERIAL DESHIDRATADO TIENE LUGAR POR MEDIO DE LA GRAVEDAD.
