Mar 27, 2020 Ball mill charge becomes measurably swollen only when there is a buildup of large unground material in the ball mill or when the density of the pulp in a wet mill is extremely high. Although these conditions are seldom encountered, it is recommended that ball mills be ground out prior to shutdown for measurement of the charge level.
In agency, this becomes a 40 to 50 percent attack, behind a while a bigness dullness considerably inferior than that of stacked rods. Ball mill attack becomes measurably distended merely when there is a buildup of abundant unreason symbolical in the sphere mill or when the dullness of the pulp in a wet mill is greatly excellent.
