Operating Principle
- The ability of glazed tiles to resist surface abrasion encountered in everyday use is determined by abrading the glazed surface either with wet abrasive media consisting of steel balls of 1 to 5 mm diameter, aluminum oxide abrasive powder and distilled water, or with dry abrasive media consisting of porcelain cylinders and Aluminum Oxide Abrasive Powder.
- The test is conducted by holding test specimens on a flat horizontal disc. The disc is rotated at 300 rpm with the axis of rotation displaced by 22.5 mm. The abrasive load placed above the test specimen rubs over the test surface in a circle of 45 cm diameter. The abrasive load is held in place inside a rubber-lined cylindrical metallic ring, which also keeps the test specimen firmly pressed against the metallic disc.
Construction Details
- Fabricated horizontal metal disc with motorized arrangement for rotation.
- Mild steel rotating disc with vertical axis displaced by 22.5 mm from the centre.
- Counterweight provided on the lower face of the disc to balance vibrations caused by eccentricity.
- Motor and V-belt and pulley arrangement for disc rotation.
- Pre-set electronic counter with key-lock reset and memory backup to record disc rotations and switch off the motor after the desired number of rotations.
- Rubber-lined circular specimen holding rings and holding plates with covers for holding test specimens and abrasive loads.
- Rigid metallic base construction.
- Attractive powder-coated and bright chrome/Zinc-plated finish for corrosion resistance.
- Supplied with steel balls of 1 mm, 2 mm, 3 mm and 5 mm diameter and White Fused Alumina Oxide 80 Grit.
- Other grinding media available at extra cost.
