- Los Angeles Abrasion Testing Machine
|
|
The machine is for determining the resistance to wear of small size coarse aggregates and crushed rock. The machine consists of a hollow cylinder, mounted on a sturdy frame on ball bearings. A detachable shelf which extends throughout the inside length of the drum catches the abrasive charge and does not allow it to fall on the cover. The drum is rotated at a speed of 30-33 rpm by an electric motor through a heavy-duty reduction gear. Motor is suitable for operation on 415V, 3 Phase, 50 HZ, AC Supply.
Supplied complete with a tray for collection of the materials with revolution counter and abrasive charge.
Spares:
* Abrasive charge, consist of a set of 12 hardened steel balls of 48mm dia. Approx.
* Revolution Counter

- Tile Abrasion Testing Machine
|
| |
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 revolution 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 kg. 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 volts A.C., three phase electrical supply.
On request machine to operate on 230 Volts A.C. supply can also be supplied.

The concrete test hammer is an instrument which is easy to use, for quick and approximate measurement of the resistance to pressure of manufactured concrete products. The principles on which it works are based on the rebound impact of a hammer on a piston which rests against the surface of the concrete products. The Greater the resistance of the concrete, greater is the rebounded impact. By reading this rebound impact on a scale and relating it to curves on graphs supplied with the instrument, the resistance to compression in MPa or PSI can be found, with 20% of actual.
Salient Features
- Specifications:
- Consists of a barrel in which is housed a hammer mass attached to an impact spring which slides on a guide bar. A plunger is attached to the guide bar which is pressed against the surface to be tested. As the piston is pressed against the surface to be tested, on reaching the compressive strength, the hammer mass is released and rebounds to a certain extent (according to the strength of the surface) which is indicated by a rider on a calibrated scale. A lock button fixed on the body of the hammer locks the rider in place and the rider can be recared to zero position by using the same button. The equivalent compressive strength can be computed from the chart supplied. Each hammer is calibrated against at standard test hammer, and is suitable for specimen of compressive strengths 100 - 700 kg/cm. The instrument, complete with a grinding stone for polishing the test surface, is supplied in carrying case.
