Section snippets Theoretical background. The discrete-size continuous-time Population Balance Model (PBM), a batch grinding kinetics model, has been proved to be well successful in not only the design and optimization of mills but also predicting and simulating the evolution behavior of the particle size distribution in large industrial-scale Suitable for grinding raw materials with Moh’s hardness below 9. Compared with ball mill, higher grinding efficiency, small occupation. Particle size can be adjustable by adjusting parameters such as grinding medium, amplitude, and frequency.

Assisted by the impact and abrasion between media (steel ball, steel rod, gravel, ceramic ball) and ore, the grinding operation reduces the particle size in the mill [[1], [2], [3]]. To produce the qualified size and high liberation of granule for the subsequent separation is the primary objective of the grinding operation [4,5].A and b is collectively called impact parameters, and t a is called abrasion parameter. These parameters are well suited for simulations of AG/SAG (autogenous and semi-autogenous) mills, crushers, HPGR (high pressure grinding rolls) [22]. JK impact parameters, A and b are usually obtained by fitting the JK drop-weight test data into JK A novel and direct approach for modeling and simulation of impact grinding

Quartz is a piezoelectric material that exhibits a strong luminescence caused by mechanical loading. This is a reason for intensive use of quartz for studying of luminescence-related phenomena. Pacovich [4] and Streletsky et al. [5] reported about the study of luminescence of quartz induced due to grinding in lab scale vibration mill.where μ is the viscosity of the suspensions, (dV/dr), shear velocity, and n, an indicator which depends on the nature of the fluid flow in the gap.Figure 1 shows the diagram of the cavitation-impact colloid mill which represents an improved version of MKI-160 mills.
