According to this classification, there are dry calcium carbonate grinding mill and wet calcium carbonate grinding mill. Besides, due to different designs and working principles, there are varied kinds of limestone grinding mills, such as Raymond mill, ball mill, vertical mill, hammer mill, and so on.
Calcium carbonate was chosen as a model material since its behavior during stirred media milling is well representative of the majority of inorganic or organic materials. It is obvious that many parameters related to the mill geometry, the operating mode and to the formulation of the suspension, affect the grinding result.
Dry grinding of calcium carbonate means to obtain ground calcium carbonate powder by grinding slumps of limestone or marble, rather than the slurry version. To grind calcium carbonate in a dry way, a calcium carbonate plant often includes a set of machinery, such as grinding mill, conveying device, classifier, dust collector, silos and so on.
The ball mill had a solidtoliquid ratio of 2000 g/L, and a materialsball mass ratio of The mean size of the slag particles decreased from 18 μm to μm after 1 h of grinding. They found that the surface area of the slag significantly increased, which, in turn, increased the degree of the hydration reaction.
The ultrafine calcium carbonate ball mill plant is a new energysaving and efficient grinding production line that combines the selfdividing flow micropowder classification technology with the ultrafine ball milling technology.

Most of the grinding plants for calcite are equipped according to the setups of tumbling mills such as ball mills. However, it would be much more logical to replace such plants using ball mills for calcites with types of equipment based on vertical mills characterized by lower energy consumption and higher capacity.
1. Introduction. The history of grinding aids in dry fine grinding processes starts in the late 1930s with the application of the first commercial grinding aids in the cement industry [1].Since that time, the importance of grinding aids in industrial dry fine grinding processes has strongly increased; so did the number of scientific papers dealing with this topic.

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].
