Multifunctional Ceramic Testing Equipment Cement Pavement Concrete Tiles Deep Abrasion Ceramic Tester

The ability of unglazed tiles to resist deep abrasion is determined by holding the tile under test in a vertical plane and pressing it against a steel disc rotating at a specified speed, used for Unglazed Tiles. The abrasive material of specified grit size is dropped from a funnel at fixed rate so as to fall between the face of the tile under test and the steel disc. The length of impression produced on the surface of the tile under test is measured. The volume of material abraded away from the tile is calculated to evaluate resistance to deep abrasion of the tile under test.

The Resistance to Deep Abrasion Tester for unglazed tiles consists of a metal disc held with its axis lying in a horizontal plane, a motorized arrangement to rotate the disc, a pre-set type electronic counter to record the number of rotations of the disc and also to automatically stop the motor after a preset number of rotations, a frame to hold the test specimen in a vertical plane tangential to the circumference of the metal disc, a trolley on which the test specimen holder is mounted and dead weights to pull the trolley to press the test specimen against the metal disc.

The metal disc is made of commercially available mild steel. It can be rotated about a horizontal axis at the specified speed with the help of an electric motor and a two stage V-belt and pulley arrangement. A pre-set type electronic counter with reset and memory backup is provided to record the total number of rotations of the disc and also to switch off the motor after the desired number of rotations.

The test specimen is held in a clamp such that its upper face lies in a vertical plane and can be pressed against the outer face of the metal disc. The clamp is mounted on a wheeled trolley moving over guide rods. the trolley can be pulled with the help of dead weight to press the test specimen against the metal disc.
