STANDARDS : ASTM D4644
This equipment has been developed to assess the durability of rock to weakening and disintegration when subjected to the simulated effects of climatic slaking.
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.
The system incorporates a motor drive unit mounted on a baseplate which revolves two (or up to four) stainless steel drums manufactured from 2 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 (see accessory).
Power supply: 230V 1ph 50Hz 250W
Dimensions: 350x740x300 mm approx.
Weight: 30 kg approx.
