Calcined bauxite is produced by sintering/calcining with natural bauxite ore of low iron, low alkali at temperatures of 1600 - 1800 degree Celsius in the rotary kiln or round kiln through pre-heationg, calcination, cooling and other processes. During Calcining, it can be removed impurities and improving the content of alumina. Refractory grade bauxite has high refractoriness, good mechanical strength and moderate slag resistance. Therefore calcined bauxite is one of the most important raw materials for the production of shaped and unshaped refractories for the steel industry, foundries, glass and cement plants.
Dead burned magnesite 97% is a chemical substance, which means that when magnesite is calcined at 1800C, carbon dioxide completely escapes, and magnesium oxide forms a dense block of periclase. This dead burned magnesite has a high degree of fire resistance. Its main component is magnesia, which is made of natural special magnesite magnesia through flotation purification, light burning, fine grinding, high pressure ball pressing, and ultra high temperature oil shaft kiln calcination. Application: Dead burned magnesite 97% are made from sorted super grade natural magnesite through sections including float concentration, calcination, fine grinding, high pressure briquetting and ultra high temperature sintering in heavy oil shaft kilns. They are good quality materials for making magnesia bricks and monolithic refractories. Packing: Jumbo bag(or according to the customer requirement)
