Quantifying the effect of clinker grinding aids under laboratory
The effect of clinker grinding aids (GAs) on mill performance and cement properties is currently quantified in real-scale grinding plants. In fact, laboratory-grinding mills operated for given time interval do not consider the effect of circulating load, thereby leading to increased specific energy consumption (Ec) with excessively wide cement 行星式球磨仪 PM 100 Wet and nano-scale grinding with the PM 100. Wet grinding is used to obtain particle sizes below 5 µm, as small particles tend to get charged on their surfaces and agglomerate, which makes further grinding in dry mode difficult. By adding a liquid or dispersant the particles can be kept separated.行星式球磨仪PM100--德国RETSCH（莱驰）研磨仪粉碎仪

Cement dry-type ball mill is mainly used for grinding raw materials and clinker (finished products and raw materials) in cement plant, and also for grinding various ores and other grindable materials in metallurgy, chemical industry, electric power and other industrial and mining enterprises. It can be used for open flow grinding and circularMost of the available studies on the investigation of GAs in continuously operated grinding plants focus on closed-circuit operations with tumbling ball mills. For instance, Sottili and Padovani [11] showed that industrial closed-circuit grinding of cement clinker using a tumbling ball strongly benefits from GA applications.

Industrial versus Laboratory Clinker Processing
The evaluation of grinding aid (GA) effect on clinker processing in laboratory grinding mills is relatively simple. Yet, the results obtained cannot be directly transposed to industrial mills, given the The specific rate of breakage (S i) in the widely accepted first-order expression of grinding rate is one of the important factors required to evaluate a grinding process, particularly for the initial grinding stage in various mill types.In this study, the effects of ball diameter and feed size on the specific rate of breakage were investigated on A study on the specific rate of breakage of cement materials
