Early resistance of old cyclone preheater rotary kiln larger, mainly due to imports of cut cyclone preheater rotary air to air collision with internal interference, the gas-solid two-phase flow field is changing. Transformation through the addition of the spoiler, you can reduce the collision interference effects, and stable flow, reduce flow in the cyclone preheater rotary kiln within the travel and reduce the amount of air circulation to reduce the cyclone preheater resistance.

 Rotary deflector is too short, reduction in resistance is not obvious, long hand, significantly affect the separation efficiency, or even increase resistance. As the rotary spoiler role in the reduction in resistance was more evident under certain conditions, so the transformation, when you can easily volute, to transform the inner cylinder, when, by taking reasonable volute, tube structure within the rotary kiln form and reasonable parameters, can significantly reduce the resistance of the system, which produces the effect of changes is equally clear, and not necessarily have to use spoiler, after all, to increase after the preheater structure components complicate the maintenance phase of increase in long-term adverse operating conditions may be deformed or broken, hand rotary kiln system will run rate of adverse effects. Conversely, if the traditional form of rotary kiln preheater system can not be a big transformation, the use of deflector plates is an effective modification measures.

 Gas from the inlet to the cyclone preheater rotary kiln exhaust outlet of the campaign process is similar to "Tornado", the last chance to enter the cyclone air pre-heater of the cone at the discharge nozzle, will be separated once again roll down the raw material starting out with central air preheater cyclone to reduce the separation efficiency of the system. The traditional cyclone preheater rotary kiln, cyclone preheater rotary kiln of its height H and the ratio of the effective diameter Di small. In the transformation, combined with the original equipment, frame size, should be possible to transform all levels of post-cyclone preheater rotary kiln to import centerline length of the discharge opening is greater than the "Tornado" length, tail away from the wind discharge nozzle.
