Process for the preparation of high alumina cement

A process for the preparation of high alumina cement using production equipment comprising (i) a submerged combustion melter (1) comprising melting chamber walls (19) and a melting chamber bottom, submerged combustion burners (21, 22, 23, 24, 25, 26) arranged at the melting chamber bottom, a raw material discharge or feeder (10) and a melt outlet (9), (ii) a melt cooling station, and (iii) a grinding station;

• the process comprising:
• introducing a solid batch material for the preparation of high alumina cement into the melter (1);
• melting the solid batch material in the melter (1) by submerged combustion to form a liquid melt, wherein one or more burner nozzles are arranged in the melter bottom;
• discharging at least a portion of the liquid melt from the melter (1);
• cooling the discharged liquid melt to obtain a solidified melt;
• and
• grinding the solidified melt using the grinding station to produce high alumina cement grains.
