TILE ABRASION TESTING MACHINE





Description:

 

TILE ABRASION TESTING MACHINE:

AS PER IS: 1237 & 1706.

 

Introduction: Natural building stones used in stops, floorings, pavements etc are subject to heavy wear and tear as well as friction. Their durability under such circumstances can duly be ensured only by stones which have the necessary hardness and resistance to abrasion. Similarly flooring tiles are chosen for their elegant appearance and also the case with which they can be laid.  A tiled floor apart from looking pleasant easily adopts itself to slight settlement of the foundation backfill.  If at all there is a crack due to this it will be imperceptible and localized in joints only. Added to this they have good strength, durability, resistance to wear and can easily be replaced. The Tile Abrasion Testing Machine is for testing the resistance to wear and abrasion of natural building stones, and cement concrete flooring tiles.  The instrument is as per ISL 1706 and IS 1237.

 

General Description and Specifications:

  • 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 tace-wise under specific load on a grinding path and abrasive powder is evenly spread on the rotating grinding path and after specific number of revolutions of the 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 rpm 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 preset counter automatically stops the machine after 22 revolutions.
  • This counter is re-adjustable.
  • The machine works on 440 volts AC, three phase electrical supply. On request machine to operate on 230 Volts AC supply can also be supplied.
