Discription of rotary drum granulator
Rotary drum agglomerator/granulator (also known as balling drums or rotary granulators) are very versatile pieces of equipment that can process a wide array of materials
The equipment is typically used for high capacity applications and usually requires some type of recycle depending on the product specifications
Drum granulators are used when an agglomeration - chemical reaction process is required
Typical applications of a rotary drum granulator include, but are not limited to the following:
Agglomeration involving chemical reactions where the feed component(s) consist of reactive liquids or gases
The liquid and/or gas can be added into the bed of material to get a complete reaction and contain or reduce any emissions that may be generated
Many inorganic fertilizers are produced in this manner
Conversion of fine mineral ores into easy to handle agglomerates or balls for further processing
Iron ore, copper ore, and gold ore are a few examples
Granulation where the only feed or the majority of the feed is a liquid or melt such as urea granulation
Coating of finished products by spraying a liquid onto the bed of material
