How can the efficiency of clinker cooler be increased without any modifications?

I can't recall any really good articles on the formation of snowballs but know they can be quite frightening. They are caused by variations in the clinkering range or flux content of the feed. Mostly they break up under the flame but I have seen monsters fall into the cooler, which is quite alarming and can cause major damage. This happened occasionally in one kiln where I was involved and we traced the problem to variations in the MgO content of the limestone and kiln feed. That might be the answer.

What are the possible causes of large snowballs occurring in a short precalciner kiln, which build up and eventually cross into the burning zone, and require a stoppage to break them up.

Regarding silicon carbide blocks in cooler to ease the removal of snowman, would you kindly send installation's name available in cement plant. Can you also please suggest LSF, S/R & A/F values to be maintained to avoid snowman. Kindly suggest any other parameters for raw mix and process to be maintained.
