Modelling of crushing operations in the aggregates industry
create more environmental friendly quarry operations. Two major issues in quarry operations are: 1. Energy Wastage due to inefficient flowsheet development of the quarry processing operations 2. Generation of fines from crushing (nominally -4 mm) which cannot be utilised and sold. These sometimes have to be stored and stockpiled on site.

aggregate crushing plant presentation
After primary crushing/reduction the resulting aggregate generally is placed in a large "surge" pile where the aggregate may be fed into the secondary operation whenever convenient. Care is always taken when building up and loading out surge piles, as this step may be a major source of segregation of material going to the secondary plant.
