Improving yield and shape in a crushing plant - ScienceDirect

This final stage in the crushing plant produces high quality aggregate for both asphalt and concrete. It is essential to minimise the production of particles sized 0–2 mm and to produce as cubic particles as possible for all fraction sizes larger than 2 mm. The particle shape was measured in FI (Flakiness Index), (SS-EN 933-3).
