Pan pelletizer operation is oftentimes considered an art because of the many mechanical and process variables that must be properly combined to achieve the desired pellet characteristics. A trained operator is necessary to create the most efficient pelletization process, and the most ideal end-product. The list below outlines the variables that must be considered during pan pelletizer operation:
Mechanical variables:
- Pan angle
- Pan speed
- Spray nozzles (including nozzle quantity, location, type etc.)
Process variables:
- Raw material characteristics (fine/course; sticky/not-sticky)
- Ratio of dry to wet product
- Binder type
- Desired size of finished product
- Raw material moisture content
- Feed Rate
- Binder Rate
While the mechanical and process variables are wide and far, they offer an opportunity to fine-tune and customize the pelletization process unique to a specific material, and ultimately create a premium end-product.
