Experimental technique to analyse the slurry erosion wear due to turbulence

Erosion due to turbulence is a predominant factor in plant design for slurry handling. DUCOM Instruments (P) Ltd. has built a “counter rotating double disc erosion tester” to analyse surfaces for erosion due to turbulence. Volume loss of Stainless Steel and aluminum as a function of varying time, particle hardness, speed and slurry concentration is evaluated in this erosion tester. Individual study on the effect of corrosion on the total volume loss is conducted and found to be high in alumina slurry and low in silica slurry.
