Increase in the efficiency of water transport of bulk mineral cargo by the segregation of feedstock at the initial technological stage

The paper gives the analysis of the volume of transportation of bulk mineral cargoes by water transport. It is established that the problem of the use of technological processes for sorting non-metallic building materials and coals transported by water transport is relevant. It is revealed that in t...
