Wet agglomeration

These relationships predict the binding Hquid content for wet agglomeration with an accuracy of only ca 30%. The Hquid content required to agglomerate a particular feed material depends, for example, on the interfacial properties of the system (45). Typical values of moisture content required for hailing a variety of materials are listed in Table 2. Very accurate information on the optimum Hquid content to agglomerate a particular feed material must be obtained from experimental tests.

Very often the bonding of wet agglomerates uses a combination of mechanisms III.l and III.2. In that case partial volumes exist which are completely filled with liquid while in others liquid bridges prevail. 

An important parameter of wet agglomerates is their liquid saturation l> the relative amount of voids filled with liquid ... 

Assuming that the density Pw of the liquid (in most cases water) is known and the mass of the wet agglomerates M>v+s had been determined prior to drying, the liquid saturation can be calculated from M>v=Mw+s s ...
