  • Details
  • Overview:

    The Rock Disintegration Test Apparatus is a testing instrument primarily used to determine the durability disintegration index of rocks. It can assess the long-term resistance of rocks to disintegration after undergoing repeated cycles of drying and wetting due to climatic factors. The equipment features two drum-shaped specimen chambers that are rotated at 20 revolutions per minute by a motor mounted on the baseplate. The drum-shaped specimen chambers are fitted with lubricated bearings, ensuring smooth rotation with minimal friction. These chambers are constructed from corrosion‑resistant materials and are equipped with two water tanks. The apparatus is widely applicable in universities, research institutes, testing centers, and other institutions for the determination of clayey rocks and weathered rocks, among others.
