Abstract

La presente invención hace referencia a un procedimiento y a un dispositivo para separar una carga (3) adherida sobre la pared interna de un contenedor (2), en particular de un tubo de molienda (2). Para separa la carga (3) adherida, la cual se denomina también como "carga congelada", al movimiento se le aplica una perturbación recurrente sobre el movimiento de rotación del tubo de molienda (2). La perturbación recurrente, de manera preferente, se produce mediante una corriente de perturbación (?I), que se ha aplicado en la corriente del motor (I). De este modo, la corriente de perturbación (?I) preferentemente se selecciona mediante el tipo de carga y/o mediante las propiedades físicas del molino tubular. Mediante la invención al menos se simplifica en alto grado la separación de la carga (3) adherida. De manera opcional o alternativa, la perturbación recurrente puede tener lugar también mediante una perturbación mecánica (ms).
