1. Introduction. The term chemical additives or grinding aids (GAs) refers to any substance which results in increased grinding efficiency and reduction in power consumption when added to the mill charge (amounts not exceeding wt.% of the feed) during grinding [1], [2], [3].The use of grinding aids to increase mill throughput is quite common in the cement industry [2], [4], [5].

In light of these drawbacks, Industrial Sonomechanics has developed a flowthrough, ultrasonic wet milling process, which employs highamplitude ultrasound to quickly reduce the size of CaCO 3 particles down to the required d 50 < 3 µm level. This method is directly scalable, has no need for expensive steel or silica media, requires reduced dispersant amounts and can achieve greater ...

1. Fine grinding in the mining industry. It has been estimated that approximately 2% of the world's energy usage is applied to mineral comminution, and around a quarter of this is used specifically in metalliferous ore grinding [1] where it is typically the most energy intensive set of operations [2].The purpose of comminution in ore processing is to reduce particle size in ...

Grinding time is related to media diameter and agitator speed via: T = KD 2 /N 1/2. where T is the grinding time to reach a certain median particle size, K is a constant that depends upon the material being processed, the type of media and the particular mill being used, D is the diameter of the media, and N is the shaft rpm. This equation shows that total grinding time is directly ...
