Rotary Kiln

Qingdao Three-Star Diatomite CO., Ltd is specialized in the design and production of Special Equipment for Diatomite,Rotary Kiln. Founded in February, 1995, Qingdao Three-star Diatomite Co., Ltd is engaged in development, production and sales of diatomite products as well as design, production, installation, shakedown test and technical training of diatomite whole sets, being a comprehensive enterprise which takes the lead in passing ISO9001 International Quality System Certification, ISO14001 Environment management System and Occupational Safety and Health Management System (OSHMS) among the production enterprises of diatomite. By right of many years’ deploitation and practice, our products have made their application expand quickly in every business area and could compare favorably with imported products of the same kind. At present, the ACHANG diatomite series produced by our company have developed four major categorize including over twenty models, with the annual throughput of 18,000 tons. Equipments and production technology of environmental protection and energy saving type specialized for diatomite and powder that are designed and developed by our company have gained several national patents; and tested by environmental protection departments, all of their guidelines have met the requirements of environmental protection. This set of craft and equipments is favored by customers at home and abroad; besides, we have formed cooperative relation with many countries. It is advantaged diatomite resources, advanced production craft and equipments together with our painstaking work that gestate today’s SANGXING. In the future, we shall strengthen cooperation with universities and innovate and develop constantly. 　Diatomite series products are carefully made from sediment of single-cell alga water plant. Because the category of diatorm is complex and porosity, the diatomite products has the un-competitive filtraing capability and absorbent capability than any other filtrating medium, at present it is widely used for filtrate-supporting dose, stuffing and carriers. 　　The diatomite series products made in our factory use good quality diatomite which contained more than 87 of silicon dioxide as its raw material, adopting purified coal gas as its fuel, it is formed after burning in revolving kiln and gas-dividing. The diatomite based products can be divided into the following three categories by production process: Dried product: After the raw diatomite is dried under 100℃ to 200℃, and then purified by high pressure gas flow pulverization, the product can be made by classification, it appear grey white-light yellow. Roasted product: The product is made through roasting the cleaned diatomite under high temperature of 700℃-900℃, high pressure gas flow pulverization and classification, it appears orange and brown. Melting aided roasted product: The cleaned diatomite is mixed with proper amount of melting additive, ang roasted under 900℃
