The possible reasons of cyclone jamming

1.Molar ratio not balanced.

2.Higher than the normal volatile matter i.e. S03,K2O & Na2O & Cl. in the hotmeal

3.Obstruction in the cyclone i.e. tipping valve not functioning properly.

4.Bricks or coating stuck-up in the meal pipe.

5.Over-burning and incomplete combustion of fuel in main and calciner.

Please analyse the blockage material by conventional wet method and mineralogically/microstructurally by XRD and Optical microscopy to find out the root cause of cyclone blockage.These are the ways to analyse any problem.Without pain there is no gain.
