Abrasion tester boehme

The instrument measures a volume loss in a specimen under abrasion test and it’s used in tests such as:

– paving stones
– concrete slabs
– slabs made of natural rocks
– natural stone slabs

The test is performed by positioning a specimen to be verified in a abrasion tester Böhme apparatus on the test track on which has been spread normalized abrasive; the grinding wheel it’s made rotate and the specimen submitted to the abrasive load of 294 N for a certain number of cycles. Before doing a test, establish the specimen’s bulk density by measuring weight and thickness. Perform the test for 16 cycles composed of 22 turn each, calculating at the end a worn as a average loss in volume and weight. The apparatus is basically composed of:

– cast iron horizontal disc with a speed of 30 rpm and a diameter of 750mm furnished of a 200mm test track to position a specimen.

– separate control panel with digital revolutions counter with automatic stop after preset revolutions

– specimen’s holder

– adjustable charger used to produce a force of 294 N ± 3 N on a specimen

Power supply: 230V 50Hz 1PH 800 W

Dimension: 1500 x 1000 xh 850 mm

Weight: 250 kg
