Abstract

Raw stock for cement and sulphuric acid manufacture is obtained by mixing, without a joint milling step, CaSO4 residues with the usual additions such as clay, sand, coke and pyrites, both the residues and the additions having a particle size less than 0.090 mms. Any coarse CaSO4 residue present after drying and calcining is comminuted before being added to the separately ground additives.
