Solutions of Unstable Incoming Material of Rotary Kiln

In normal production, raw material feeding volume is fluctuating, but the fluctuation range is small. But when the equipment there are some problems, or in the rainy season raw water is not easy to control, prone to raw materials in the library top or library wall agglomeration, resulting in poor cutting, there will be greater volatility. In this case requires the operator to ground observation, ground adjustment, but also a certain degree of predictability. According to some of the current changes in the delivery device to determine the amount of material. Pre-response measures reduce the production, quality and adverse effects of equipment.

(1) When the incoming materials less, should not extend into the coal pipe, open large exhaust, elongated flame, so that the temperature will rise sharply kiln, decomposition furnace, cyclone temperature will soon rise, Which can easily cause the cyclone tube or cutting the pipe of the bond or even plug, rotary kiln furnace and the decomposition chamber is also easy to crust, and the system resistance increases. When the material is less correct method of operation is: appropriate to the coal pipe out a little, off the small exhaust, reducing the decomposition furnace and the kiln feed coal, control the temperature and the temperature of the cyclone cylinder, and adopt short flame burning, waiting for the arrival of materials.
(2) When more incoming, there will be positive pressure kiln head there, cyclone exit and decomposition furnace temperature, kiln temperature will drop sharply, this time should be appropriate to reduce the kiln speed, reduce the feeding volume, open large exhaust, also can be appropriate to add coal, but must not be too much, otherwise it will cause reduction atmosphere, so that the temperature inside the kiln is lower, so that the temperature of the kiln can be increased. When the kiln main motor current decline faster, to reduce the kiln speed, out of the coal injection pipe, appropriate to adjust the small amount of exhaust, this time can be short flame burned to make it back to normal. When the kiln conditions are normal, and then feeding, do not feed to mention the temperature, this will make the operation in a passive state, production, quality is also difficult to be guaranteed.
