LOS ANGELES ABRASION TESTING MACHINE

TECHNICAL DESCRIPTION :
Used for testing Crushed Rock, Crushed Slag, Crushed and Uncrushed Gravel For Resistance to Abrasion.
The machine consists of a hollow cylinder mounted horizontally on a study frame on ball bearings. There is an opening which can be closed with a dust tight cover to facilitate charging and discharging the drum with the material under test. A detachable shelf which extends throughout the inside length of the drum which catches the abrasive charge and does not allow it to fall on the cover. The drum is rotated by an electric motor through a heavy reduction gear at a speed of 30-30 33 R.P.M. A revolution counter is fitted to the frame. A tray is supplied for collection of the material at the end of the test. Complete with. Abrasive Charge consisting of a set of Twelve hardened steel balls, approximately 48mm dia. Suitable for operation on 440 V, 3 Phase, 50 cycles, A.C. Supply.

TILE ABRASION TESTING MACHINE

TECHNICAL DESCRIPTION :
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

TILE FLEXURE STRENGTH TESTER

TECHNICAL DESCRIPTION :
As per IS-653-1962. For the determination of breaking load of clay roofing tile.
The equipment consists of two bearing rollers and one loading roller all 40mm diameter. The centre of bearing rollers can be set at 250mm or 270mm. The loading is done through a double lever loading system by means of a steady flow of lead shot from a container into the receiver hung on the lever system. The lead shot flow stops automatically when the specimen fails. The lead shot can be weighed and the load taken by the tile calculated by multiplying by the lever ratio i.e. 12.Maximum capacity of the machine is 2KN. Lever ratio is 1: 12.Supplied complete with all accessories
