The aggregates on which the crushing test was performed had been obtained either by dry sieving for 12 studies, or by wet sieving for 20 studies (see Table 1). To evaluate the amount of carbon protected within aggregates, the authors systematically monitored the carbon mineralization from the soil with the intact versus crushed aggregates.

Hence, the black mass created during the initial crushing consists of a higher graphite content, which can be easily recovered by sieving. Consecutive two-step separation in zigzag air classifiers generates a separator concentrate containing the plastics, an electrode mixture, and a housing fraction [ 9, 96 ].

Sieving is usually used as a preliminary separation treatment after crushing, according to the differences in the particle size distribution of each component. He and Zhang et al. conducted detailed chemical and mineralogical characterization of waste LIB, and discussed possible crushing, sieving and separation methods ( Zhang et al., 2014a ).

back is that sieving—especially wet sieving—requires significant manual operation, which makes it costly and dependent on operator skills. Some automation is possi-ble but requires more expensive equipment. Some examples of sieves are shown in Fig. 8.1, together with the logos/names of the major manufacturers of sieves.

All quarries applied drill and blast to extract the rock, followed by crushing and sieving. The crushed rock was transported to storage piles or to further processing. The drilling, located on top of the quarry bench ( Fig. 1 ), was occasionally present in Quarries 2, 4, 5 and 6 during the measurement days.

The more reclaimed asphalt pavement (RAP) is used in asphalt production, the more properties of the pavement depend on the characteristics of the RAP. Crushing and sieving of RAP into different fractions are the most used means of RAP processing that can allow ensuring consistency and the desired properties of the produced mixture.
