As Per IS 2386 (P-IV)
Specification :Aggregate Impact Value Test Apparatus is used for determining the aggregate impact value. The Sturdy Construction consists of a base and support columns to form a rigid framework around the quick release trigger mechanism to ensure an effective free fall of the hammer during test. The free fall can be adjusted through 380±5mm. The hammer is provided with a locking arrangement. Aggregate impact value test apparatus is supplied complete with a cylindrical measure of 75mm dia x 50mm depth, an automatic blow counter and a tamping rod.

As Per IS 2386 (P-IV) ASTM: C131, AASHTO T-96
Specification: Los Angeles Abrasion Testing Machine is used for determining the resistance to wear of small size coarse aggregates and crushed rock. The abrasion testing machine consists of a Closed hollow cylindrical steel drum rotating around its horizontal axis on ball bearing units mounted on a sturdy base framework at a speed of between 30-33 rpm. Supplied complete with subtracting revolution counter to preset the number of revolutions, a sample collection tray for removal of the sample on completion of testing and set of 12 abrasive charges.The los Angeles Abrasion testing machine is fitted with 1 HP Motor. Suitable for Operation on 440V, Three Phase, 50Hz, AC Supply.

ASTM D2-33 & IS 2386 (PART IV)For The Determination of Resistance of Aggregates to Wear by Abrasion.
Specification: It consists of two hollow cylinders closed at one end and provided with Fitting covers at the either end. These cylinders are mounted an a shaft 0 at angle of 30 with the axis of rotation of the shaft. The shaft rotates at 30-33 RPM. Through a reduction gear operated by a motor and is provided with a revolution counter. Complete with Abrasive Charge consisting of 12 Nos. Hardened steel Balls of 48mm dia. Suitable for operation on 440 Volts, Three Phase, 50 Cycles, A.C. supply.

Aggregates which are flaky and/or elongated will often lower the work ability of a concrete mix and may also affect long term durability. In bituminous mixtures, flaky aggregates make for a harsh mix and may also crack and break up during compacting by rolling. The flakiness of aggregate is determined by measuring the thickness of individual particles. Hence we offer thickness gauge and length gauge to check flakiness and elongation index of the aggregate respectively.

AS PER IS: 2386 (Part- III)Determines bulk density or unit weight of aggregates.
Specifications:Calibrated cylindrical measures of sheet iron with handles. Consists of 3 measures one each 3 liters to 30 liters capacity. Complete with one tamping rod, round, 16mm dia. and 600mm long, one end rounded.

BS 812For Testing Aggregates for Resistance to Abrasion.
Specification: It consists of a disc rotating about a shaft connected to a reduction gear box coupled to a motor. The disc rotates at 28-30 RPM. Under the rotating disc is a tray with an outlet to facilitate the removal of sand. Two Conical Hoppers are mounted on a bracket fixed to the circular tray. An arrangement is made for start and stops the flow of sand. Two containers with weights are supplied to keep the specimens pressed against the rotating disc. Suitable for operation on 220 V, 50 cycles, A.C. Supply.

The crusher has maganess steel jaws. The opening of the jaws is adjustable from 20 mm to 6 mm. The capacity is 200 kg/hr. The crusher is made of cast steel. The jaws have forward and downward strokes with sufficient rocking action to throw crushed material down to the jaws. A hopper is provided at the top for pouring material. The crusher is supplied complete with 3 h.p. electric motor, triple V-belt pulley drive and mounting frame.

The Laboratory Pulverize is a disc type grinder, designed to grind virtually any material to produce a fine mesh sample in one operation. The instrument is useful for assaying , mining and for metallurgical, quarrying, aggregate processing, chemical, geological and industrial laboratories. It is a self contained grinder, with a rotary disc, having a planetary movement in a vertical plane. This feature gives added life to the moving parts and produces a sample of uniform fineness. Grinding is done between two discs-one stationery and the other revolving eccentrically at high speed. The discs are made from heat treated machinate metal. With the help of a convenient hand wheel, the size of the final product can be adjusted. This can be done, even while the machine is in operation. A self locking device holds the hinged grinding chamber in place and affords easy and quick access to it, for removal of ground samples and for cleaning. The Pulverize has a capacity of reducing about half of a kilogram of a quartz type sample to 100 mesh in a about a minute. The Pulverser is supplied complete with a 3 H.P motor, a starter, a "V" belt pulley drive and mounting wired for 440V, 3 Ph, 50Hz, Disc Diameter:175m, Maximum Feed size: 6mm. Yield: 250gms./min, Size of Finished Product: 100mesh.

IS 2386 (PART-III) & BS 812For Density Tests on Aggregates as per Procedure Laid Down.
Specification: Made of Brass/GI with Stainless steel Wire Mesh 6.3mm/4.75mm size Ruggedly Constructed, Approximately 20cm dia x 20cm high. Complete with Handle.

Riffle sample divider is required for the rapid collection of true representative samples from aggregates, sand and fillers. Riffle Sample Divider consists of a metal box fitted with a series of chutes of equal width which discharge the material alternatively in opposite directions into separate pans. The chutes of the riffle are steep enough to allow rapid flow of the material. The sample divider is supplied with two containers and a sampling scoop.
