It is actually a pressure vessel, so it is filled with steam till it is very warm and rolls at varying speeds. A solution is then sprayed on it which immediately evaporates the free water, then we scrape the “dried” Potassium off of it. Creating a finished product ready to be milled and sifted to whatever granulation customer requests. It is one of a pair. We have several pairs. This set needed a new finish. It has been a long few days getting to this point. We literally roll two of these side by side at less than twenty thousands apart. Enough to suspend solution and yet allow dried material to pass. Apologies I went all engineer geek!
