fines generation iron industry

Estimation of Fines Generation in Blasting Using

2020-6-16  At iron ore and coal mines, respectively, fines can be defined as 6.3 mm and 1.0 mm [8]. Therefore, it is important to define the size of the fines before investigating their generation. In this study, fines are assumed to be 75–1000 μm, the typically accepted size in hard-rock mining [2, 9, 10].

2007-1-1  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.

2007-1-15  in fines production during the crushing of single aggregates and aggregates within granular packs. Results show that particle-level loading conditions determine the failure mode, resulting particle shape and fines generation. Point loading (both single particles and grains in loose packings) produces clean fractures and a small percentage of fines.
