Belt-Cooling Pelletizing System PFS Series 30

The Belt-Cooling Pelletizing System PFS is specially designed for water soluble and brittle formulations. The variable system configuration enables perfect adaptation to the product being processed and guarantees continuous manufacturing. Even elastic and very flexible polymers can be handled by the belt system in a simple and efficient way. The system produces top-quality cylindrical pellets or micro-pellets which are ideal for further downstream processing.
