A HOLLOW STEEL CYLINDER WHICH IS CLOSED AT BOTH ENDS, WITH INSIDE DIAMETER OF APPROX. 700 MM AND INSIDE LENGTH OF APPROX. 500 MM. THE CYLINDER MOUNTED ON A STURDY FRAME ON BALL BEARINGS. THE OPENING WILL BE CLOSED DUST TIGHT WITH A REMOVABLE BOLTED COVER IN PLACE. THE DRUM IS ROTATED AT A SPEED OF 30-33 RPM. BY AN ELECTRIC MOTOR THROUGH A HEAVY DUTY REDUCTION GEAR. FITTED WITH COUNTER AND PUSH BUTTON STARTER. SUPPLIED COMPLETE WITH A TRAY FOR COLLECTION OF THE MATERIAL. SET OF 12 NOS ABRASIVE CHARGE - CAST IRON SPHERES OR STEEL SPEHERES APPROX. 48 MM DAIMETER

EACH WEIGH BETWEEN 390-450 GRAM.

This machines used the for determination of resistance to wear by attrition iron cylinders 20 cm. dia 34 cm. long with dust and water-tight covers, mounted on shaft with their axis inclined at 30 deg. to the axis of rotation of the shaft. Rotation speed is 30-33 rpm.

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 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 volts A. C. , three phase electrical supply

For conducting torsion and twist tests on various metal wires, tubes, sheet materials .

It is based on the Constant hydraulic principle. The machine provide tension & compression test .load frame depend on the machine capacity. Middle slide is moving with the help of leading screw and upper slide is stile with help of two pillars. And lower slide up & down with help of hydraulic cylinder to control oil tank, pump and two wall & limit switch to auto stop. Pressure Tran juicer and sensor connected directly indicates the load & displacement (elongation) in Digital form in Newton and kg as we set and displacement show in mm. Middle slide traveling speed is 80mm _+ 5mm per min. lower slide traveling speed is 25mm _+2mm per min. measuring the load with help of hydraulic pressure

Tile Flexure Testing Machineis used to determine the flexural strength of clay roofing tiles and cement concrete flooring tiles. We are one of the leading manufacturers of Tile Flexure Testing Machines. Our machines are manufactured using best raw materials to ensure good functionality and durability.
Functionality :
The Tile Flexure Testing Machine is a double lever loading machine where load is placed by a flow of lead metal that automatically stops as the sample breaks. The sample is mounted between rollers which are 40mm or 12mm in dia. Bearing rollers can be placed at center distances of 150, 200 or 270mm. The unit comes equipped with a 20 Kg lead metal.

Hand operated with accessories, helical springs . Machine enable to load deflection tests of tension and compression springs to be carried out accurately & quickly. The machine should be capable of accommodating 8 length dia rod up to 4 dia, springs for tension, 6 length dia, rod, 4 springs for compression. Scale graduations up to 15cm.
