Features

• The machine comprises a hollow cylinder that is mounted on a robust frame on ball bearings.
• A detachable shelf that spreads throughout the inner length of the drum catches the abrasive charge without allowing it to fall on the cover.
• The drum is revolved at a speed of 30-33 RPM through an electric motor by a heavy duty reduction gear.
• Motor is apt for operation on 3 phase, 440 volts, and A.C. supply.
• The unit should be offered with a tray for accumulation of the material with abrasive charge.
• It is also be supplied with 12 nos. hardened steel balls (Abrasive Charge) of 48mm dia.

The marshall stability & Compaction of mix is defined as a maximum load carried by a compacted specimen at a standard test temperature of 60ºC. The flow value is deformation the marshall test specimen under goes during the loading upto the maximum load, 0.25 mm units. In this test and attempt is made to determine optimum binder content for the type of aggregate mix and traffic intensity.

The reaction container is one of the most important apparatus required for determination of the potential alkali reactivity of aggregates by chemical method. It is made from stainless steel and fitted with an air tight cover which is held in position with the special clamp.
