LIQUID PHASE

Good day experts.

Can someone tell me the general effects of a high and low liquid phase, both positives and negatives?

Thanks.

Re: LIQUID PHASE

  Liquid formation is important for

ü       Effective Granulation and formation  of clinker

ü       Stable coating

ü       Protecting the refractory

 

At the same time excessive coating will lead to

Reduced kiln diamater and hence reduced prodn

Ball formation

Reduced consumption of silica/lowgrade limestone

Frequent coating fall and unstable operation

 

% Liquid =        2.92 Al2O3

                                    + 2.25 Fe2O3

                                    + Mgo    

                                    + Alkali

 

Normal range 25 % to 28%

Vinayak

Re: LIQUID PHASE

Hi Stephen,

In addition to the good information that Vinayak has provided, excessively high liquid phase may also promote attack of the bricks, "washing out" of coating, hard to grind clinker and increased tendency to form "snowmen" in the cooler.

Excessively low liquid phase promotes little or no coating, very hard to burn clinker (high free lime), increase in clinker dustiness and high thermal loads.

Also, liquid phase is inversely proportional to the Silica Ratio. 

Hope this helps,

Ted.
