Aggregate production: Fines generation during rock …

The generation of fines increases when shear is imposed during crushing. Aggregates produced in current crushing operations show the effects of multiple loading conditions and fracture modes. Results support the producers'' empirical observations that the desired cubicity of aggregates is obtained at the expense of increased fines generation when standard equipment is used.

Fines/dust generation and dispersion are influenced by blast design parameters and execution (Bhandari et al, 2004). The fine material is assumed to originate from a cylindrical crushed zone around the blast hole, within which particles are generated by the crushing of the rock due to comprehensive-shear failure (Kanchibotla et al, 1999).
