Disc agglomerator operation

Mixer-agglomerators The mechanisms of agglomeration in mixer-agglomerators are very similar to those in the drum. While industrial drum and disc agglomerators always operate continuously, mixer-agglomerators may be batch or continuous. The mechanisms are different in both cases. 

Other advantages claimed for the disc graniilator include low equipment cost, sensitivity to operating controls, and easy observation of the granulation/classification action, all of which lend versatility in agglomerating many different materials. Dusty materials and Chernies reactions such as the ammoniation of fertilizer are handled less readily in the disc granulator than in the drum.

Finally, an agglomerator design combining features of both the inclined disc and the horizontal drum should be noted. This machine, known as a cone pelletizer, is described in Fig. 3.17 and Table 3.4. As the name implies, the vessel is in the form of a truncated cone and the scraped inner surface has a bowl-like shape as build-up takes place during operation. The cone...

Often, only the easily determined moisture content is measured and reported. Such data normally show a wide scatter which may result in misleading conclusions. After introducing the pellet porosity and calculating the liquid saturation, the scatter is reduced to yield more reproducible data (compare Table 11). At optimum operation of the granulation disc, pellets feature nearly constant saturations between approximately 80 and 95 7o. The lower than expected saturation figures are caused by air entrapped in the structure by pores that are completely filled with liquid and surround such areas. If moisture contents deviate considerably from these values, agglomerates with low quality are produced (compare Figure 128).
