Appareil de durabilité Slake

The Slake durability apparatus has been developed to assess the deterioration of rocks over a period of time when subjected to water immersion.

The rock samples are dried and then submitted to wear stress inside a drum which is rotated into water. The test is performed different times and the wear is given by the loss in weight of the sample.

This Apparatus consists of a motorized drive unit which is mounted on a baseplate and which can rotate two or four drums at a speed of 20 r.p.m.

The tank assemblies are filled with water to a level 20 mm below the drum axis. The test drums are manufactured from 2.00 mm mesh, 140 mm dia. x 100 mm long.

A digital timer automatically stops the motor after the preset time. The equipment is supplied complete with two drums with tanks, and it can accept two additional drums.
