Tile Abrasion Testing Machine 
Ref. Standard IS:1237, 1706

EKE 466:

The tile sample is pressed under a specified load against a grinding path, strewn evenly with 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 .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 pre – set revolution counter and one 7.5 kg weight, but without abrasive  powder and thickness measuring device. Suitable for operation  on 415 V, 50 Hz, 3 Phase , AC Supply
