Analysis on rotary kiln Secondary air supply
Great Wall rotary kiln has advanced technology supporting and sound after-sales service,Hereby Great Wall company as the professional rotary kiln manufacturer with over 50 years experience,we analysis on the reasons of high temperature in rotary kiln secondary air.
1:the granularity is good shaped,however the materials layer is thick in cooling machine first cavity.
2:the fire length is too short,which causes the thermal zone shift forward and raises the temperature of calcining clinker.
3:the fire is so scattered that coarse coal powder mixes with clinker and continues combustion after entering into cooling machine.
4:Clinker granularity is too fine,which makes the material layer resistance increase,reduces the secondary air volume and raises air temperature,so that there are a lot of fine grained clinker back rotary kiln along with secondary air.
