Analysis of technical-technological parameters of secondary impact rotary crusher in limestone processing
This paper deals with the production of limestone at the stable plant separation of the open pit 'Duboki potok-Bijela rijeka'. Besides that, the effects of different levels of production and material flows were researched. Research was carried out in a fixed plant separation of the open pit limestone 'Duboki potok-Bijela rijeka' in Duboki Potok. Positions of research were on the secondary part of separation (impact crusher, routers materials, funnels, rubber conveyors, vibrating screens, etc). In the course of using different methods of measuring material flow, calculating capacity conveyors, laboratory methods where used in measuring size and distribution obtained material, and particle shape. The research results were reported in: - particle size distribution diagrams of the obtained aggregate stone with the best bands of particle size distribution - defining the functional dependence of impact crusher gap size distribution and structure of the obtained materials.
