Laboratory crushing of rock aggregates Semantic Scholar

In the present study laboratory crushing was carried out on four rock types in one Swedish and four Finnish laboratories. Flakiness index, grain size distribution, and mechanical properties (resistance to abrasion) of the aggregates were analysed. Run characteristics and crusher settings were monitored from crushers. The results of this study indicate that standardisation of laboratory ...

Crushing in Mineral Processing

2015-12-26  Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface. Less abrasive and softer rocks or stones are crushed by impact and shear but also compressive mechanisms.
