Appareil pour mesurer la durabilité Slake

Specimens are placed inside the wire mesh drums, which rotate at a constant speed of 20 RPM via a motorized mechanism. The drums operate inside water-filled tanks up to a designated level, and throughout the test cycle, the specimens are subjected to continuous wetting and mechanical abrasion. This process simulates natural weathering conditions in which rocks undergo repeated contact with rainfall, streams, or groundwater. At the end of the test, the specimens are dried and re-weighed to calculate the Slake Durability Index, which numerically represents the rock’s resistance to moisture-induced disintegration. The wire mesh drums used in the device allow free water circulation while securely containing the specimens. The motor system operates at a constant speed to ensure identical test conditions for each run. A digital timer allows the operator to preset test duration, and the motor automatically stops at the end of the cycle, providing both convenience and repeatability. With its compact size and robust construction, the Slake Durability Apparatus can be easily integrated into laboratory settings. Its durable steel structure ensures long-term stability and consistent performance, even under frequent use.
