Tile Flexure Testing Machine - ASI-644

Tile Flexure Testing Machine - ASI-644

Unit for finding flexural strength of clay roofing tiles and Cement flooring tiles. Flexural load is applied on the tiles using lead shots. The machine consists of a stand on which two 40mm dia. bearing rollers or 12mm dia. rollers are placed at centre distance of 150mm, 200mm, 250mm, or 2720mm as the case may be, The third upper roller applies centrally flexural load by means of lever arrangement. Lead shot contained in an upper vessel start flowing into lower container at a rate of 45 to 55 kg per minute of 200kg per minute there by, starting loading the specimen. Arrangement is made such that loading automatically stops when specimen breaks. Supplied without lead shots.
