Description and Specification for Lab Tenders
Astra Scientific Tile Abrasion Testing Machine.
Specification: This is used for determination of resistance to wear for
Cement & Concrete flooring tiles. Tiles specimen of size 7.06 cm x
7.06 cm is pressed face-wise under specific load on a grinding path and
abrasive powder is evenly spread on the rotating grinding disc the
second parallel side of the tile is subjected to wear for similar number
of rotations. The wear of the tile is measured on a thickness gauge
specifically made for the purpose. The machine consists of a disc
rotating at a speed of 30 R.P.M. in a circular tray. A bracket is
provided to hold the specimen. A counter balance lever loads the
specimen. Load applied is 30 Kgf. A funnel is fitted to evenly spread
abrasive powder on the grinding path. A Pre-set Counter automatically
stops the machine after 22 revolutions. This counter is Re-adjustable.
The machine works on 440 V A.C. Three Phase electrical supply. On
request machine to operate on 230 V A.C. Supply can also be supplied.
