Optimisation of pre-blending process for raw materials in quarrying
ABSTRACT. The negative effects of using fossil fuels and production costs are major problems for cement industry. In this study, the unit production costs and CO 2 emissions from raw material production were calculated for cement quarries. A mathematical model was used to blend the raw materials produced by the cement quarries.

Sea water forces air into cracks and joints in the rock. The pressure from the waves on this air causes the cracks and joints to expand. When larger, loose blocks of rocks are eroded in this way, it is called wave quarrying. If the waves are very large, cavitation will occur. High-pressure air bubbles in the wave collapse on the rock ...
