Abstract

LOS MOLINOS DE BANCADA CONTINUA - CONTRARADIACION SON MOLINOS DE RADIACION GASEOSA CON LOS QUE SE ALCANZAN MUY ALTOS GRADOS DE FINURA EN EL MOLIDO CON UN DESGASTE EXTREMADAMENTE PEQUEÑO. UNA MEJORA EN LOS RESULTADOS EN EL MOLIDO SE OBTIENE MEDIANTE EL ENFRIAMIENTO DE LA RADIACION GASEOSA CON UN MEDIO REFRIGERANTE; LA MEJORA CONSEGUIBLE NO ES, SIN EMBARGO, MUY NOTABLE, Y EL GASTO DEL MEDIO REFRIGERANTE ES MUY ELEVADO. CON EL FIN DE AMINORAR EL GASTO DE MEDIO REFRIGERANTE JUNTO A UNA MEJORA CONSIDERABLE DE LA FINURA DE MOLIDO, SE ENFRIA LA MATERIA A TRITURAR (11), SEPARADA DE LA CRIBA (5) DEL MOLINO, CON EL MEDIO REFRIGERANTE DENTRO DEL MOLINO DE BANCADA CONTINUA - CONTRARADIACION Y SE CONDUCE A LA CAMARA DE MOLIDO (2). COMO MEDIO REFRIGERANTE ES PREFERIBLE EL NITROGENO LIQUIDO, CON EL QUE SE REFRIGERA EL DEPOSITO (3) DEL MOLINO.
