The disc abrader conforming to Böhme method consists of a rotating wheel made of heavy duty steel, 750 mm dia., with a defined test track to receive the abrasive material (white corundum sand) and a no-vibration specimen holder with a two arms lever loading device. The test speciment is clamped with an holder and submitted to a test force of 294 +/-3 N. After the abrasive is strew on the disc, the disc starts to rotate with a constant speed for a certain number of cycles (according to Standards).
At the end of the test the abrasion effect is measured as the loss in specimen thickness or volume.
This machine is used for testing of:
natural stones (EN 14157)
concrete paving blocks (EN 1338), flags (EN 1339) and
kerbs (EN 1340) screed materials (EN 13892-3) tiles (EN 13748-2)
(Testing specimens in wet or water-saturated conditions is not feasible).
The machine is equipped with a display control panel that allows the setting of speed and number of cycles.
Once the machine is started, it will automatically stop at the end of the set number of cycles programmed on the controls panel. White carborundum abrasive sand have to be ordered separately.
