Using it as a raw material for aluminum chloride can reduce costs and improve product quality. Calcium aluminate powder is mainly used to produce aluminum sulfate, polyaluminum chloride, sodium chlorate and other products. Calcium aluminate powder is a white powder obtained by mixing limestone and aluminum ore in a certain proportion, grinding them, calcining them in a rotary kiln, and then grinding them again; calcium aluminate calcined in a rotary kiln usually condenses into blocks or large particles, and needs to be further ground into calcium aluminate powder of the required particle size.
