Grinding & Classifying Systems

  • Clay Grinding Systems

    Applications, Process, Properties
    Clay is widely used for floor-, wall- and roof tiles, bricks and hollow gauged blocks in the building industry. Clay is manufactured in a wet or dry process. Grinding and drying of raw material is done before mixing with water and storaging on wet piles. Clay has a flaked or layered shape, a good affinity for water and a tendency towards high plasticity while being wet. After baking the clay converts into a ceramic material.
