Slake Durability Apparatus simulates weather-related wetting/drying cycles to evaluate the durability of rocks (shale and weak rock). Samples are rotated at 20rpm in 5.5 x 3.9in (140 x 100mm) Dia. x W Wire Mesh Drums within 11.5 x 8.5 x 7.5in (292.1 x 215.9 x 190.5mm) WxDxH Water Tanks, then oven-dried for two cycles. The Slake Durability Index is the percent sample loss after subsequent wetting and drying cycles.
The 4ft (1.2m) wide base can accommodate a total of four Water Tank and Drum Assemblies. Additional Water Tank and Drum Assemblies, Wire Mesh Drums, and Water Tanks can be purchased separately for increased sample testing.
