Rotary Kiln Calcined Bauxite For Refractory Industry

Refractory grade bauxite   Calcined bauxite is produced by sintering/calcining of low iron, low alkali containing raw bauxites at temperatures of 1600 - 1800 degree Celsius. In this calcination process the high refractory mineral phases corundum and mullite are formed. 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.       Application     Refractory applications remain the premiere non-metal market for calcined bauxite which is mixed with binders and pressed, extruded, cast and shaped into a variety of forms that are then dried and transfered to kilns for firing. The calcined refractory grade bauxite is also used in unfired monolithic refractories.   It should be noted that another source of materials suitable for refractory use is the calcined bauxite used to produce brown fused alumina, which has higher mechanical and chemical corrosion resistance than other high alumina refractory raw materials.     SINOCEAN Available Refractory Grade Bauxite   Item  SNR90  SNR88  SNR87  SNR85  SNR80  Al2O3(%)  90.0min  88.0min  87.0min  85.0min  80.0min  SiO2(%)  3.5max  5.5max  7.0max  8.0max  10.0max  Fe2O3(%)  1.5max  1.6max  1.8max  2.0max  2.5max  TiO2(%)  3.8max  4.0max  4.0max  4.0max  4.0max  CaO+MgO  0.35max  0.40max  0.40max  0.40max  0.50max  K2O+Na2O  0.35max  0.40max  0.40max  0.40max  0.50max  B.D(gm/cc)  3.35min  3.25min  3.20min  3.10min  2.90min  Moisture  0.3max  0.3max  0.3max  0.4max  0.5max       Available grain size  0-1mm; 1-3mm; 3-5mm; 5-8mm; 16-30mesh; 30-60mesh; 120mesh; 200mesh; 325mesh or as customer's requirement.    Package 1MT Jumbo bag Standard exporting package for sea transportation or air delivery Special packing requirement is acceptable  Company information Sinocean Industrial Limited is an investor, producer and supplier of calcined bauxite & related products to a wide variety of industries throughout the world.
