An evaluation of the procedure and results of laboratory

2004-2-27  Quality estimation of rock aggregate raw materials is often performed with mechanical tests on aggregates crushed with laboratory crushers. However, standardised mechanical tests are intended for testing products, not raw materials. Different laboratory crushers produce aggregates with varying shape properties [flakiness index (FI), shape index and surface roughness], and this has a

Evaluation of size reduction process for rock aggregates

2020-6-4  The size reduction process of rocks in cone crushers is one of the most important issues, particularly for the secondary and tertiary stages of crushing operations.
