Abstract
Some operating characteristics of heading-and-winning machines ‘Ural-20R’ were subject to investigation. It was proved that the scope of effective application of these winning machines is restricted by the capacity of the loading operating equipment: screw conveyors and chain-and-flight conveyors. The potash solid destruction by means of the business end of ‘Ural-20R’ machines is supplemented by intense ore circulation and over-degradation when transported using single-thread screw conveyors. Feeding of ore in discrete quantities to the conveyor causes significant base plate vibrations and formation of dynamic loads on drive elements of chain-and-flight conveyors. When using winning machines in workings at a negative inclination angle, flight-and-chain conveyors capacity decreases significantly. Technical proposals on the improvement of potash ore loading process efficiency were developed based on the analysis of specific design properties of screw conveyors and ‘Ural-20R’ combined machine conveyors.
