Hello paloturk,
There are many kinds of different agglomerators and the choice depence on capacity of processing,properties of your material and on the target properties and price of your product: particle size distribution, uniformity, the amount and sort of a binder and some other properties like flowability, stability, rate of dissolution, final moisture content etc. If you are dealing with a pharmaceutical product in a range of maybe hundreed kg/day you will probably use more expencive and complex technology batch process(fluid bed agglomerator)compared to a continuous fertilizer agglomerator with a few tons/hour output.
