Grinding of highly viscous bentonite containing slurries
This work showed that the presence of bentonite had adverse effects on the grinding performance mainly due to the high swelling capacity of bentonite. When the solid percentage of the bentonite-containing slurries was higher than 62%, the grinding performance was significantly reduced. However, the addition of Ca 2+ ions significantly Grinding Aids for Mining Applications.

Cement grinding optimisation ScienceDirect
The world energy consumed for cement production is similar to energy used for grinding in US mining industry, which is a significant fraction of the world total. In the minerals industry, research in modelling and simulation of the grinding process has a long and successful history. Grinding aids for dry fine grinding processes Part I1. Introduction1.1. 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 Stirred media mills in the mining industry: Material

Influence of Sodium Hexametaphosphate on Muscovite Grinding
In this paper, different doses of sodium hexametaphosphate (SHMP) were added as grinding aids in the process of muscovite grinding, and the effect of SHMP on the grinding efficiency of muscovite was studied. The grinding experiment results show that the grinding efficiency increases significantly with the increase in SHMP dosage. The 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.Grinding aids for dry fine grinding processes ScienceDirect

Coatings Free Full-Text Effects of Grinding Aids Used in Grinding
In the cement and industrial mineral grinding technologies, liquid grinding aids are used to prevent the coating-effects on grinding media and mill equipment, agglomeration of fine particles, to increase the grinding performance, fineness of the product, and energy efficiency [1,2].Amine and glycol compounds are the most widely Introduction. The production of fine particles in the lower micron range by dry grinding processes demands large amounts of energy. For instance, the cement industry alone consumes approximately 12–15% of the world’s total industrial energy, whereby the fine finish grinding of the cementitious products accounts for about 30% of the overall Comparative study of the grinding aid effects for dry fine grinding

Towards waterless operations from mine to mill ScienceDirect
The advantages of using grinding aids are reported to be reduced energy consumption, increased production capacity and the potential to produce finer particles from grinding (Sverak et al. 2013). Grinding aids are typically active on ore surfaces causing local stresses and thus allow fragmentation at the grain boundaries during grinding.
