A slurry pot test rig is the device used to evaluate slurry erosion wear of different engineering materials under controlled conditions. Generally, two test specimens with or without propeller are rotated in solid-liquid mixture at the test speed to evaluate erosion wear with postulation of uniform suspension of solids in liquid. The arrangement of rotation of test specimens without propeller does not ensure the uniform distribution of solids in liquid while rotation of test specimens with propeller mounted on same shaft generates high strength whirlpool which renders random motion to solid particles. The evaluation of erosion wear of plane surface test specimens in terms of mass loss at different impact angles is one embodiment of the present invention. A propeller mounted on separate shaft used to rotate in down-pumping mode to suspend the solid particles. In another embodiment, the invention includes the placement of test specimens in the zone where solid particles have nearly uniform flow with minimum random motion. The test specimens are mounted on another shaft and used to rotate at the test speed in a direction opposite to the propeller rotation is another embodiment of the slurry pot test rig.
