Then, a single-pick cutting model of different damaged rocks was established. Through this model, the rock crushing process and cutting force during the cutting were obtained, and the influence of rock damage on the cutting mechanism was explored. Furthermore, the effect of rock damage on cutting force and cutting energy consumption was studied.

Learn MoreThe Bond work index is a measure of ore resistance to crushing and grinding and is determined using the Bond grindability test. Its value constitutes ore characteristic and is used for industrial

Learn MoreBond's work index is given below: The indices derived by Kick, Bond and Von Rittinger all assume a constant energy requirement per unit of size reduction regardless of the particle size range. Industrial and laboratory results indicate that the energy required for size reduction increases as the product particle size decreases.

Learn MoreDetermination of the energy consumption for ore grinding in a Bond ball mill requires samples of standard size, because changes in the size of the samples cause the change of the Bond work index (Magdalinovic et al., ). Due to the Bond test

Learn MoreComminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. In geology, it occurs naturally during faulting in the upper part of the Earth's crust. In industry, it is an important unit operation in mineral processing, ceramics, electronics, and other fields, accomplished with
