General Rotary Kiln or Rotary kiln low yields due to other reasons, the Rotary kiln conditions just getting easier fluctuations.Negative performance fluctuations up and down the table frequently, Rotary kiln drive current (or torque) can not be stable, low firing temperature fluctuated.This is caused by the accumulation of material caused by the collapse of the material in the system. Easy material in the preheater, the decomposition of some of the small platform inside the furnace, a small cone angle and other parts piled, stacked system to a certain extent when the wind speed varies, plot material will lose stability and collapse into the gas stream.Since wind speed is low, much higher than normal amount of these materials can not be uniformly dispersed in the gas stream, but in no case suitable for heat exchange and quickly discover fleeing into the Rotary kiln firing zone.
