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].
The breakage and liberation of minerals are the key to fluidized mining for minerals. In the ball milling process, steel balls function as not only a grinding action implementer but also energy carrier to determine the breakage behavior of ores and the production capacity of the mill. When ground products present a much coarse or much fine particle size distribution, the separation process ...
In contrast to manual grinding, which is open and susceptible to a range of environmental factors, 20 ball milling offers an enclosed solventfree reaction environment with welldefined parameters for optimizing reactivity, such as frequency, mediumtosample weight ratio, etc. 21,22 Among different mill designs, 23,24 shaker and planetary mill ...
