Consequently, as a mill is progressively filled, the noise level within it is progressively decreased; conversely, as amil is progressively emptied, the noise level is progressively increased.
A material which is hard to grind will have a longer retention time and cause an increase in the amount of material charge.conversely,
easier to grind materials will have a shorter retention time and cause a decrease in the material charge.

BENEFITS
         • Improve the uniformity of grind
         • Reduce operator supervision
         • Reduce labor costs
         • Reduce mill liner, ball and rod wear per unit of product
         • Decrease power costs, per unit of product
         • Improve productivity
         • Reduce Overgrinding
         • Eliminate plugging and loss of production

FEATURES
         • Up to five (5) inputs from various monitoring points on the mill
         • Discrete 4-20 mA outputs for each point being monitored
         • Simple to install
         • Ideal for dry and wet grinding processes
         • Greater control over varying conditions in your grinding mill due to changes in specific gravity or hardness
