Rotary Kiln Is a Mineral Processing Machine

The dry crude materials enter the kiln outlet, i.e. the high end of the cylinder through the preheater, and then are fed into the kiln by the tremie pipe. Due to the inclination of the cylinder and slow rotation of the material, the materials roll in hoop direction. On the other hand, the materials move from the high end to the low end, where they are decomposed, burnt, cooled in succession. Thus they become cement clinker, and are discharged from the low end of the cylinder. Finally, they enter the cooling device.For external-heating Cement Rotary Kiln , Materials do not have direct contact with fire and smoke , the heat source lies between heating furnace and the cylinder .Through transfer from heat-resisting Steel , Material is heated . The heating furnace is covered with refractory fibre , which can save energy and consumption . As limited by the cylinder material and heating method , the length of hongxing barrel is not more than 15 meters , with heating temperature not exceed 1200℃. Compared with internal-heating cement Rotary Kiln , the external-heating cement Rotary Kiln have smaller production .Applicable heating methods are : electric heating , fuel gas , fuel oil , bunkercoal and etc .Henan Hongxing machinery co.ltd. specially produces Mineral Processing Equipment, crushing equipment, Sand Making Equipment, drying equipment, and fertilizer making equipment (and sell more fittings of these equipment). The refractory bricks are selected according to distribution of stress and heat stress in the inner side of kiln. Ceramic rotary kiln is high temperature calcinations equipment and in which refractory bricks accept heat stress actions. Especially in the burning zone of kiln body the refractor bricks are pressed by pull tress, press stress and cut stress so the refractory bricks are required for this place having high mechanical strength and heat shock resistance.At the present, Hongxing mining machinery has set up three state level machinery research...
