Micro-Deval apparatus
Twin-drum micro-Deval apparatus for determining the wear resistance of aggregates in the presence of water.
- 24-month warranty and spare parts from stock
- Commissioning, staff training and methodological support
- Assistance with equipment certification as part of your laboratory
Description
The micro-Deval apparatus evaluates the wear resistance of crushed stone and gravel: the sample is abraded by steel balls in a rotating drum with added water, simulating the behaviour of the aggregate in a road pavement.
The apparatus is equipped with two sealed stainless steel drums, allowing two samples to be tested in parallel and halving the duration of a test series. The electronic counter switches off the drive precisely after 12,000 revolutions.
Features
- Two stainless steel drums for parallel testing
- Sealed lids with quick-release clamps
- Automatic stop at the preset number of revolutions
- Set of ⌀ 10 mm abrasive balls in the scope of supply
- Protective guard with a limit switch
