Caustic Calcined Magnesia

Caustic Calcined Magnesia (CCM) is made from Magnesia ore (MgCO3) through calcination in various types of shaft kilns. There is a variety of grades differing in a wide range of chemistry and physical properties. This active Magnesia compound can be widely used in many fields, such as chemical industry (paper and pulp, water purification, desulphurization), agriculture (fertilizers, animal feed), metallurgical industry ( slag splashing in steelmaking), building industry ( fireproof and light partition boards) medicine, rubber, refractories etc..

Caustic Calcined Magnesia Balls

Caustic Calcined Magnesia Balls (CCM Balls) are made of ordinary CCM powder by mixing and compressing into ball-shaped briquettes. It is mainly used for slag conditioning and slag splashing in the converter steelmaking process.

Dead Burned Magnesia

Dead Burned Magnesia (DBM) is made of finely-selected high-quality raw magnesia ores by different ways of beneficiation, calcined in various types of shaft kilns. With high sintering level and compact structure, DBM is an excellent raw material for producing shaped and unshaped refractory products for a wide range of applications, in electric furnace, converters, ladles, tundishes, as well as for many other Magnesia-based products.<br /> The DBM grades containing 90-93% MgO with heterogeneous structure is produced by selective mining of appropriate grades of Magnesia ore. After hand selection follows single step calcination at over 1600°C in vertical shaft kilns. After post-burning selection, crushing and screening to customized sizes (from lumps to fines) create the various grades, well established for the production of monolithic and low category burnt bricks.

Middle-grade Dead Burned Magnesia

DBM 95: The group of DBM grades with MgO contents of 94-95% MgO are made by 2 step calcination. The first step is shaft kiln caustic calcining, followed by milling and briquetting, then sintering at over 1850°C temperature shaft kilns. Featured with good sintering and dense crystallization, it is an excellent material for making mid-range Magnesia shaped and unshaped refractory products.
