Essay

With the help of physical and computer simulation as well as with natural observations in the laboratory environment, the microstructure of flotation concentrate cake tailing and its influence on vacuum dehydration indices has been investigated in the thesis. It is experimentally determined that slightly quantity of big canals in cake microstructure denotes its penetrability and filter discrimination. It is defined that during the stage of sediment collecting, pores are mainly of round form and at the stage of drying they become elongated ones. The experimental dependence of sediment penetrability on the structure of porous medium is established. The technological characteristic of filtration of coal slurry at continuously functioning filters are investigated and improved. The release testing of the recommendation are carried out.
