Abstract

SE REFIERE A UN DISPOSITIVO DE SEPARACION CARACTERIZADO PORQUE INCLUYE UN TANQUE ESPESANTE CILINDRICO, Y UN RASTRILLO MONTADO ROTACIONALMENTE DENTRO DE DICHO TANQUE. DICHO RASTRILLO INCLUYE UNA PLURALIDAD DE BRAZOS DE RASTRILLO QUE SE EXTIENDEN RADIALMENTE CADA UNO INCLUYENDO UN ARREGLO DE HOJAS ESPACIADAS QUE SE EXTIENDEN HACIA EL TANQUE. EL DISPOSITIVO DE SEPARACION INCLUYE ADEMAS MEDIOS DE TOPE DE DETENCION DISPUESTOS PARA RETARDAR LA ROTACION DEL FLUIDO DENTRO DE DICHO TANQUE EN RESPUESTA A LA ROTACION DE DICHO RASTRILLO. ADEMAS DE UN METODO PARA REDUCIR EL DONUTTING DENTRO DEL TANQUE ESPESANTE EN RESPUESTA A LA ROTACION DEL RASTRILLO. DONDE ESTE METODO PODRA SER APLICADO EN UN PROCESO PARA EXTRAER LOS SOLIDOS DE LAS SUSPENSIONES Y PULPAS MINERALES
