Our calcium aluminate powder rotary kiln, the minerals through 1300 --- 1500 ℃ calcination, after cooling to obtain calcium aluminate products. The kiln has a simple structure, reliable operation, easy to control the production process and so on. Calcium aluminum powder is made from a certain grade of aluminum ore and limestone grinding into a ball by a certain percentage, calcining, cooling, ground and become refined, has been widely used in chemical, environmental protection, sewage treatment and other fields. Another addition to the calcination of calcium aluminate this method can get outside and melting gas fired tunnel kiln sintering method. Calcium aluminate powder is mainly used to produce aluminum chloride, aluminum sulfate, sodium aluminate and other aluminum products. Also be used for adjustment of basicity, can be used for refractories. Calcium aluminum powder is off-white powder. The main ingredient is two calcium aluminate (CaO · 2A1203) and a calcium aluminate (CaO · A1203) mixtures. Slightly soluble in water, aqueous solution is alkaline, PH value of about 11. Calcium aluminum powder with an inorganic acid reactivity, occurs at room temperature to start. And heat capacity, fast heating, alumina dissolution rate of 90% or more, use it as raw material to produce liquid or solid PAC can simplify processes, reduce costs, improve product quality, is most at home and abroad polymerization chlorine aluminum raw materials used by manufacturers.
