Hemos mencionado en repetidas ocasiones el t\u00e9rmino \u00abgrado de llenado del molino con bolas de molienda\u00bb. A primera vista, es un concepto sencillo que significa la cantidad necesaria de bolas de molienda en un molino de bolas para lograr la molienda m\u00e1s eficiente del material.<\/p>\n

\"\"<\/p>\n

El grado de llenado puede expresarse en la documentaci\u00f3n t\u00e9cnica de dos maneras: indicando la masa de los cuerpos de molienda o el porcentaje de llenado del volumen interno del tambor del molino con bolas de molienda.<\/p>\n

Es importante comprender qu\u00e9 valores deben utilizarse en la pr\u00e1ctica. Esto es especialmente relevante en las pruebas industriales, donde cada tonelada de bolas de molienda no considerada puede afectar el resultado. Dado el car\u00e1cter prolongado de las pruebas industriales, el error en los c\u00e1lculos se acumula y distorsiona significativamente los resultados.<\/p>\n

Por ejemplo, el grado de llenado de un molino de bolas (78 metros c\u00fabicos) es del 44% (seg\u00fan la documentaci\u00f3n t\u00e9cnica del molino). Conociendo el peso volum\u00e9trico de las bolas de molienda, entendemos que para el funcionamiento eficiente del molino es necesario cargar 374 toneladas de bolas de molienda.<\/p>\n

Sin embargo, el di\u00e1metro interno del molino de bolas aumenta gradualmente durante el per\u00edodo de operaci\u00f3n. Esto es especialmente cierto cuando se utiliza un revestimiento de acero. El aumento del volumen del molino significa que el 44% ya no pesar\u00e1 374 toneladas, sino, por ejemplo, 400 toneladas. Este incremento en la masa total de carga puede provocar fallos en el motor, los ejes y otros componentes electromec\u00e1nicos. Adem\u00e1s, el cambio en la relaci\u00f3n entre la masa de las bolas de molienda y la masa del material molido puede dar lugar al deterioro de los par\u00e1metros tecnol\u00f3gicos de la molienda, al aumento del consumo de energ\u00eda el\u00e9ctrica, al incremento del consumo espec\u00edfico de bolas de molienda, etc. Estos factores reducen significativamente la eficiencia de la molienda y aumentan el costo de molienda de 1 tonelada de material.<\/p>\n

Para evitar esta situaci\u00f3n, los especialistas de Energosteel recomiendan:<\/p>\n

    \n
  1. Determinar el volumen interno m\u00ednimo del molino.<\/li>\n
  2. Si el fabricante del molino recomienda un llenado del 30%, el c\u00e1lculo del tonelaje de carga debe realizarse utilizando la capacidad m\u00ednima del molino. Mantener el 30% de llenado del tambor con bolas de molienda, pero sin superar el tonelaje previamente calculado.<\/li>\n<\/ol>\n

    La regla principal es no exceder este valor, independientemente del volumen interno del tambor del molino.<\/p>\n

    Esperamos que esta informaci\u00f3n le ayude en esta cuesti\u00f3n aparentemente sencilla y que el proceso de molienda en su empresa se lleve a cabo de la manera m\u00e1s eficiente posible.<\/p>\n","protected":false},"excerpt":{"rendered":"
