Manufacturing process
※This process is just one example, and the manufacturing methods vary by company.
reaction
recovery
During this process, the raw materials undergo phase transitions (from low-viscosity liquid to high-viscosity liquid, then chunk and powder), resulting in significant changes in their state. In addition, since the recovered organic solvents have relatively high boiling points, careful control of temperature and vacuum conditions is required to improve productivity.
The twin-shaft indirect heating dryer “Differential-Speed SC Processor” can stably process raw materials that undergo phase transitions or have high boiling points by the following mechanical characteristics.
Smooth conveying of high-viscosity materials achieved through the self-wiping function
Large heat transfer area ensured by the jacketed barrel and hollow shafts
Efficient processing of raw materials with high boiling points through vacuum operation
bulk density
When a liquid binder is added for granulation, a subsequent drying process becomes necessary, which may increase labor and costs, potentially reducing productivity.
The mixing and compression granulating machine - “MRCP Roller Compactor” enables binder-free granulation thanks to the following mechanical characteristics.
Raw materials are fed and pressed into the rollers by screws and paddles.
Discharged in sheet form through roller compression
Crushed into granules by a coarse crusher, then classified and adjusted for particle size
