Oct 24, 2018 First, let's define what the specific energy consumption is.
Power levels, particularly for the distribution of power between primary and secondary mills about a “design point.
Power scale up is accurate because power is measured as power consumption at the agitator shaft to determine the specific energy requirements and size the mill; and PSD scale-up is accurate because of the horizontal IsaMill™ layout, which eliminates any short circuiting, and the classifying action of the product separator.
Production is obtained from a ball mill when the mill motor power is at a maximum and consequently the specific energy consumption is at minimum.The maximum power point is dependent upon the feed material characteristics, mill liner conditions, grinding media charge and product size requirements.
