Boheme abrasion machine

This instrument measures the volume loss in a sample under abrasion test and is used in tests such as:

• Cobblestones
• Concrete slabs
• Slabs made of natural rocks
• Natural stone slabs

The test is performed by placing a sample to be tested in a Böhme abrasion test apparatus on the test track on which standardized abrasive has been spread;

The grinding wheel is rotated and the sample is subjected to an abrasive load of 294 N for a certain number of cycles. Before performing a test, establish the bulk density of the sample by measuring the weight and thickness. Perform the test for 16 cycles of 22 laps each, calculating at the end a wear as an average loss of volume and weight. The apparatus basically consists of:

• Horizontal cast iron disc with a speed of 30 rpm and a diameter of 750 mm provided with a 200 mm test track for positioning a sample.
• Separate control panel with digital speed counter with automatic stop after preset speeds
• Sample holder
• Adjustable loader used to produce a force of 294 N ± 3 N on a specimen
