Slake Durability Apparatus

The apparatus consists of a motor on baseboard capable of driving two or four drums at a speed of 20 rpm. A suitable number of plastic water troughs, each designed to contain a test drum with quick release drive assemblies, permit 1 to 4 drums to be driven at one time. The test drums are supported on water lubricated bearings allowing 40 mm unobstructed clearances below the drum and a trough water level 20 mm below the axis of the drum. Drums are made of brass and comprise 2 mm wire mesh cylinders of 140 mm dia and 100 mm length.
