STANDARD: 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 diameter x 100 mm long.
The tanks are filled with water to a level 20 mm below the drum axis.
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
