Ordinary rotary kiln feeding amount adjusting according to the thickness of the material layer in the kiln, maintain proper kiln material load rate. The feeding machine and the kiln speed synchronization, in order that we can maintain the kiln homogeneous material layer. Regulation of decomposition furnace system of feed quantity, you should take care of the two aspects, not alone in the rotary kiln, we should also as a share of consumption more than half of the decomposition furnace, comprehensive analysis judgment. But the feeding machine of the decomposition furnace should change with the corresponding changes of the rotary kiln. When the speed of the rotary kiln changes, it can keep the material in the rotary kiln. As a result of the fluctuation of the furnace, the material in the furnace residence time is short; the heat transfer rate is greater, than that of the rotary kiln adjustment, which can quickly overcome the interference factor.

Only feed quantity control in the appropriate range, so as to ensure the working efficiency of rotary kiln. When the feed quantity is not appropriate, it is required to adjust the feed quantity in time.

As a result of the flucation of the furnace the material in the furnace residence can quickly overcame the interference factor.
