[0002] Ceramic sand, as the name suggests, consists of ceramic particles. The finer particles are called sand. Also known as oil fracturing proppant, ceramsite sand is made from a variety of raw materials, including clay, slate, shale, coal gangue, and industrial solid waste, through ceramic sintering. It is generally used to replace gravel and pebbles in concrete. Ceramic sand offers numerous advantages, including low density, thermal insulation, excellent impermeability, excellent resistance to alkali-aggregate reactivity, low water absorption, and good frost resistance and durability. In ceramsite sand production, the raw ore must first be crushed using crushing equipment, followed by screening.
