In the process of continuous production and use of cow dung dryer, there may be some common problems, such as one-time drying of raw materials or the problem of raw material fire in the dryer.  Here are the causes of the problem and simple solutions.  
First, cow dung once dry reasons:  
(1) the dryer is too small  
(2) The calculation of wind pressure and flow of wind network is wrong.  
Second. Targeted solutions:  
(1), increase the temperature of the cow dung dryer, but this method is easy to cause fire in the dryer, the best way is to replace or modify the drying equipment  
(2) Require the dryer manufacturer to recalculate the air pressure and flow and then provide the design change scheme according to the actual situation.  
Thrid, the raw materials in the cow dung dryer fire cause:  
(1) Improper use of dryer equipment  
(2) the dryer equipment is too small to achieve the drying effect and forced heating causes fire  
(3) There are problems in the design principle of dryer equipment  
(4) The principle can not be sucked away, resulting in fire in the dryer  
Last. Targeted solutions:  
(1) Learn the correct use method of dryer according to the instruction  
(2) replace or transform the dryer equipment  
(3) Require the manufacturer to replace or transform the dryer equipment  
(4) check whether the dryer equipment is installed correctly, whether air leakage or increase the air pressure.
