This paper sets out the methodology and presents the results of calculation the efficiency of transport system in separation of the OP "Dimnjače", based on the data of monitoring the operating time and downtime/failure. Properly determined state of operation of the transport system, allows preventive measures and selection of maintenance strategy. Data collection lasted a year, and the data were analyzed, and thus the results are given by month for the transport system as a whole.
This paper will demonstrate the methodology and results of analysis the stationary phenomena upon gravitational pipeline transport of brine from the Salt Mine Tuzla to the ultimate consumer. Moreover, it will provide the analysis of reciprocal effects of flow, change in diameter, speed of hydraulic ascent, loss of pressure and density of brine.
The present paper analyzes the operation of the plant for washing stone aggregate 0/2 mm. Researches were conducted on a semi fixed plant for washing aggregates at the open pit 'Drenik' in Srebrenik. Positions of exploration works were on dispenser entrance points, hydrocyclones, distribution system for water supply rubber belt conveyors, etc.). The methods for measuring material flow, calculation the capacity of conveyors, laboratory methods for grain-size distribution of the obtained material were used in this work. The research results are present in the form of tabular data and dependence diagrams of filler content (fractions of technical stone aggregate, granulation -0.063 mm) on capacity of dosed material.
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.
