In the WET PROCESS method, Clay from storage bins is shifted through a belt conveyor. During movement in the conveyor, unwanted materials are sorted out from the clay by manual inspection.
The clay from the conveyor is then shifted to high speed blungers connected with VFD motors. Here the clay is dispersed in water medium by using additives like sodium silicate, sodium carbonate, dispex etc. For better dispersion normally a very high ratio of water is always preferred.
The blunged clay liquid slurry is passed through the series of magnets and sieves where all the iron and other impurities like free silica, organic materials and carbonaceous materials are removed.
This slurry is then passed through filter presses where the formed clay cakes are removed and shifted to a pug mill.
Here the caked clay is pugged and the formed cylinders are transported to a shredding machine where the clay is shredded into nodules.
Then this is shifted to a dryer normally heated with hot gases in a rotary dryer. The dried clay nodules are bagged according to the grades, stored and sent to various end users according to their requirements.
Normally the clay manufactured in this process is very costly however the properties are very superior when compared to the dry processed clay.
