20、 reduce contact time between material and high temperature gas flow and avoid material returning,material can be fed in drying area equipped with lifter flight.Chapter 2 Product IntroductionDue to inclination of shell and rotating movement,material can be uniformly scattered and fed into high temper

21、ature media inside for heat exchanging to keep material dry;vibration device is mounted at feeding end of shell to prevent fertilizer from melting on the inner wall due to high temperature and keep drying operation normal.1.Starting operation steps:(1)Ignite to rise temperature in combustion chamber

22、;flue gas can empty by emptying chimney.(2)Start motor for dryer to keep running normal.(3)Start end gas system.(4)Close wind valve and start blower to draw hot flue gas into dryer;meanwhile adjust temperature at each point up to pre-setting value as per process regulations.(5)Put necessary dried ma

23、terial into dryer.Chapter 2 Product Introduction2.Stopping operation steps:(1)Stop putting wet material into dryer.(2)Before stopping,we firstly stop supplying fuel to combustion chamber;after stop feeding wet material for 15 minutes,open exhaust air valve and stop air entraining machine;stop supply

24、ing gas to dryer.(3)After completely discharging from dryer,we can stop the machine when temperature of shell drops up to 60 avoid shell bending and out of sharp.(4)During stopping due to faults,we shall immediately stop feeding material;and let flue gas empty and press fire;then spiral the machine

25、about one circle by manual(or auxiliary drive device will side-start auxiliary drive)for 10-12 minutes until shell cools;at that time,it can be stopped.Chapter 2 Product IntroductionNew Words and Expressionsdryer dra n.吹风机；干衣机；干燥剂compound kmpand n.场地；复合物;fertilizer ftlaz n.肥料，化肥preliminary prlmn()r
