Kiln commitment

摘要

CALCINATION IS ONE of the key heat treatment processes for a range of industrial minerals, and most crucially for dolomite, limestone, and magnesite. Recent market demand for the calcined grades of these minerals is reflected in the number and range of orders of the world's leading kiln developers, the Maerz-Polysius-RCE Group. Polysius Group is a combination of three leaders in the field of calcination and mineral processing technology which have merged together over the last few years (see panel). In essence, Polysius specialises in the design and engineering of kilns and furnaces for the calcination of limestone and dolomite, magnesite, dolomite, and tabular alumina, calcination of flotation concentrates, and filter cakes as well as the thermal treatment of minerals. The accompanying table highlights some of the orders received by RCE for new shaft kiln installations over the last two years. The company is largely active in most of the major calcined magnesia projects that are in the process of development.
