Principle of the Drum Flaker Adhesion Growing layer Second layer Crystallization Further Cooling Scrape off Principle of the Drum flaker Features of the Drum Flaker Simple process: Simple operation Long lifetime Machine can be encased Toxic, smelling products Inertisation possible Sublimating products Completely closed cooling circuit Compact equipment Low energy consumption 4
Principle of the Disc Pastillator Dosing / Feeding Pastille Formation Crystallization and cooling Pastille scrape-off / discharge Features of the Disc Pastillator Machine can be encased Toxic, smelling products Inertization possible Sublimating products Completely closed cooling unit Compact equipment Low energy consumption Uniform Pastilles Example: MA Solidification Installations in Hungary and China Objective (Market requirements) Free Flowing Dust free No lumps Question Most efficient technology: Pastillator versus Flaker+Briquetter 5
