Description

This test method has been developed to ASTM D4644 for assessing the deterioration of rocks over a period of time when subjected to water immersion . The apparatus consists of a motorized drive unit mounted on a baseplate and connected to two or four drums which rotate at a speed of 20 r.p.m.
The machine mounts a digital display for the visualization of the residual testing time (10 minutes for ASTM D4644). The tank assemblies are filled with water to a level 20 mm below the drum axis. The water level is indicated by a mark.
The test drums are manufactured from 2.00 mm mesh, 140 mm dia. x 100 mm long. Two drums are already included, while two additional ones can be ordered separately, see accessories. The drums can be mounted / disassembled easily with the quick-release drive units.
  • Overall dimensions (lxdxh) with two drums standard included: 733x413x305 mm
  • Overall weight: 22.5 kg
  • Overall dimensions (lxdxh) considering the two extra drums (4 in total): 1151x413x305 mm
  • Overall weight considering the two extra drums (4 in total):  33.5 kg
