“…As the grinding size becomes increasingly fine, its energy consumption experiences exponential growth. Due to their excellent wear resistance, high hardness, and low-density characteristics, ceramic balls, a revolutionary form of grinding media, can significantly reduce the consumption of grinding power and grinding media when used in stirred mills [15,16]. According to Fang et al [17], ceramic balls were first used in the secondary mill of the two-stage grinding circuit.…”

Steel balls as traditional grinding media are prone to excessive fines generation and high energy consumption. Therefore, in light of this problem, the authors investigated another media—ceramic balls based on the output characteristics of fine particles. This study discusses the effect of ceramic balls on the change of the particle size distribution, zero-order output characteristics, micro-strain, and collision energy in ground products. The results showed that for −10 μm particle size, ceramic balls have a smaller production rate than steel balls. In addition, when the filling rate of ceramic balls is 40%, the yield of −10 μm is reduced compared to steel balls. Therefore, ceramic balls greatly reduced the overgeneration of fines. Additionally, the micro-strain rate of ceramic ball grinding with time is 67% lower than that of steel ball grinding. Furthermore, ceramic balls cannot only mitigate excessive fines generation but also effectively reduce energy consumption.
