Why Do Smoke Chamber Drop Brick In The Ceramic Sand Rotary Kiln Production

(1) ceramic sand rotary kiln side wall of the kiln inlet smoking room off the brick "backpack" in the cement plant is also a chronic problem.The higher the temperature of the smoke chamber, the material in advance part of the liquid lead to serious side wall of the crust.With high pressure water jet cleaning, high pressure cold water stream rushed on the red hot brick, and likely to cause the brick to burst off.Continuous side wall of crust, so they need to be vacuumed at least once in each class.After the burst of the brick body, sometimes one with the crusts fall off.In this way, after each inspection, the side wall of the smoke chamber ignition soon have been incidents off the brick "backpack" in some places may have to back several levels of management.(2) rotary kiln outside space, kiln inlet side wall of the smoke chamber, can be extended to shell out shift, thick firebrick alternative insulation bricks, calcium silicate boards, and every layer of refractory bricks in the vertical direction add a layer of height 20cm, castable beam (within the welding heat-resisting steel anchors to the shell), in order to improve the tension between the wall and the shell, both play an insulation role, did not increase too much weight and thickness, to avoid the smoke chamber side wall behind the brick collapse phenomenon.(3) a factory ceramic sands rotary kiln at the end of smoke chamber in the overhaul, starting from the most serious damage to the west side of the shell to the relocation of the 70mm, the original thickness of 114mm of firebrick thickening to 230mm, the original two layers of insulation material (the layer of insulating brick, thickness of 114mm; another layer of calcium silicate board, thick 30mm) into a 100mm thick calcium silicate board, and every 5 to 6 layers of firebrick plus one in the vertical direction storey for 200mm castable beam.More than 10 months after the overhaul, in addition to the refractory brick surface with minor fragmentation, the entire wall is not collapsed out of brick phenomenon.(4) for the outside space, the side wall of the smoke chamber can not be extended, not too close from the rotary kiln, playing "backpack" difficult, so i can not change the size of the original case, high-quality high-strength castable refractory bricks will be replaced by within the weld heat-resistant steel anchor.According to reports, one year after such improvements, castable was no loose, peeling phenomenon.But to do so, the construction maintenance requirements should be paid special attention to avoid castable play bad.We also provide jaw crusher,stone production line,welcome to visit our factory! henan kefan mining machinery co.,ltd.Is a mining machinery which mainly supply mining equipment, such as crusher,brick making machine,briquetting machine,rotary dryer,jaw crusher,raymond mill,grinding mill,cement mill,autoclaved aerated concrete,block machine,granulator,rotary kiln,etc.
