Sažetak
Mobile crushers on large open pits are mainly used for crushing overburden or mineral raw material prior to conveying. Parallel with truck haulage, these systems provide lower transportation costs. Usage of mobile crushers and screens on medium and small sized pits, particularly in quarrying of construction and building materials, has somewhat different objective. They are mainly used on bench for primary crushing and screening of crushed stone, which reduces loading and haulage costs. Secondly, they are used for beneficiation of old spoil dumps, low quality sections of deposit and overburden. In this way, more rational exploitation of crushed stone reduces the loading-haulage costs and environmental impact, while respecting the principles of sustainable development and energy efficiency. This paper deals with analysis of production costs in quarrying aggregates, comparing process with and without mobile crushing and screening plants.
