reasons for the steel ring formation with limestone formation

reasons for the steel ring formation with limestone formation : 1. kiln combustion temperature is too high, much higher than 

the appropriate limestone calcination temperature ; 2 , high levels of coal ash , low volatile , while on-site plus large spray of 

pulverized coal , pulverized coal is very kiln ash high ; 3 , raw sludge content is too high , sludge and coal fly ash in the Si, 

Fe, Al oxides such as CaO generated with low melting mineral phase generated in the kiln , is the main knot ring ; 4 , deep 

colored limestone of poor performance , coupled with lower raw -site screening efficiency , resulting in higher levels of 

powdered materials in the kiln , resulting in poor ventilation , the impact of lime calcination ; 5 , another through on-site 

testing, you can get the Stone Production Line negative pressure is very low, so that the amount and velocity of the secondary air is not enough 

coal combustion , leaving the high temperature zone is too concentrated, thereby generating local liquid ; 6 , to determine 

the causes of ring material is due to sludge and coal ash of Si, Fe, Al and CaO Melting minerals formed at high temperature 

kiln local lead in forming liquid liner bonded to the kiln , and then with mineral mud , ash and gravel gray adhesive into 

blocks . Specializing in the production of rotary kiln in Henan YuFeng Heavy Equipment : The main products are : lime kiln ,
