The influence of particle size on wear rate in compressive crushing of rock was investigated experimentally. A test apparatus was developed to replicate the squeezing wear that is present in many rock crushers. Silica sand of different size classes between 0.725 and 2.03 mm was used. The crushing load was varied.

The free rock crushing method involves breaking or shattering a risky block using explosive or crushing material without taking any preventive measures. This method is not preferred in areas where archaeological sites and settlements are located. Free rock crushing is generally used in open-pit mines, for opening highway routes, and in tunnels.

The weathering of silicate rock is the dominant natural CO 2 removal process over geologic time scales (Arrhenius and Holden, 1897; Urey, 1952; Walker et al., 1981; Berner et al., 1983; Brantley et al., 2023).Practitioners of ERW accelerate this natural CDR process by applying finely ground (high reactive surface area) rock powder to soils and coastal environments.

After fractal theory was introduced by Mandelbrot (1985), subsequent scholars such as Tyler et al. (1985; 1992) have established a mass fracture distribution model for the particle size distribution of rock fractures. Fractal dimension, as a key parameter, has been widely applied to quantify the degree of rock fragmentation (Li et al. 2015; Li et al. 2022; Deng et al. …
