Are You Famliar with Circumgyrate Cement Kiln?

Our country ore machine industry technology foundation is weak at present,since the reform and opening,mining machinery industry as the main way of improve the product technical level by use taking market change technology,also face the grim situation of foreign competitors invest in China at the same time. There are some problems in the dry hollow cement rotary kiln, so need modification. Through a long time practice and research, modern small dry hollow cement rotary kiln inlet dosen”t have any primary heater unit, the temperature of exhaust gas from the kiln inlet is very high, and directly discharged, resulting in a waste of thermal energy, unit clinker”s heat consumption is very high.

After a long period of trying and analysis, decide in the rotarycement kiln adopt cyclone preheater or shaft preheater, circumgyrate cement kiln outside preheating decomposition technique, these are relatively good technical improvement methods. However, due to the funds in the process of transformation is relatively high, and technical requirements are more stringent, so some manufacturers dispel the transformation plan.

Through many years of experience, circumgyrate cement kiln technology departmentsummarize some reasons: axial force of riding wheel oversize; oil selection is improper, oilviscosity is not enough; cement kiln body local high temperature radiation bearing reducelubricating oil viscosity, oil film becomes thin; radial force of riding wheel oversize, resultingin increasing the friction between axle and bearing bush, oil film may breakdown; in thebearings, cooling water interrupt for a long time, resulting in temperature increment,breaking the oil viscosity; in the bearings, lubrication device break down or points tank clogto make oil level low; the cement mill operates slowly for a long time, reducing oil spoonwith oil, and can”t meet the lubrication requirements between axle and tile; in winter andlow temperature, lubricating oil viscosity is on the high side in the bearings, bad liquidity,showing lack of oil state. Of course, maybe my summary is not comprehensive. And we also have other mining machines, such as China jaw crusher, ball grinding mill, sand making machinery and so on. If you have other supplement, you can comment about my article. We learn from each other, and make progress together.
