Tiles Testing Instruments

The tile sample is pressed under a specified load against a grinding path, strewn evenly with an abrasive powder, revolving at the rate of 30 ± 1 rpm. At the end of 100 revolutions of the disc, the second parallel side of the tile is subjected to wear for an equal number of revolutions of the disc. The wear of the tile is measured using thickness-measuring device (which is supplied at extra cost). The abrasion-testing machine consists of a replaceable grinding path, fitted on to a disc rotating about its vertical axis. The rotating disc and the grinding path are enclosed by a circular tray. A bracket holds the specimen. The loading is by a counter-balanced lever. A funnel is provided to facilitate charging the grinding path with abrasive powder. Supplied complete with automatic preset revolution counter and one 7.5 kg weight, but without abrasive powder and thickness measuring device. To work on 220V, 50 Hz, 1 phase, AC Supply.

Optional Extra Thickness Measuring Device, with Dial Gauge, having 25 mm travel and 0.01 mm least count

This is a double lever (leverage 1:12) loading machine and the load is applied by flow of lead shots, which automatically stops when the sample breaks. The load is applied at rate of 450 to 550 N/minute ( 45 to 55 kg minute) or 2000 N/minute (200 Kg/minute) and the accuracy of load indication is ± 2%. The sample is mounted between rollers 40 mm dia or12 mm dia. Bearing Rollers can be placed at center distance of 150 mm, 200 mm, 250mm or 270mm as the case may be. Complete with 20 Kg lead shots.
