According to different materials, There are several different types Ceramsites, LECA and Ceramic Sand Oil Proppant; lightweight weight clay aggregate(LECA) is mainly used fly ash, clay, sludge, coal gangue as the main material, the LECA is widely used as a substitute of aggregate in building material industry, and can use in agricultural and gardening industry, etc. the ceramic sand oil proppant is mainly used in oil and gas exploiting. The Ceramsite Sand features lighter weight, higher pressure strength, good frost resistance. A complete ceramsite plant includes crushing unit-batching and mixing unit---grinding unit ---granulator making unit---calcining process unit---cooling and screening unit---packing.
