A new underwater pelletizer from Crown Machine, Addison, Ill., has blades with four cutting edges instead of the usual two.

A new underwater pelletizer from Crown Machine, Addison, Ill., has blades with four cutting edges instead of the usual two. Cutting edges are formed on two opposing surfaces. Diametrically opposed cutting edges are formed on the same surface. Crown says this design has twice the efficiency and double the wear life of competing systems.
The unit’s Easy-Flow Anti-Turbulent Water Chamber is said to minimize random pellet impact to eliminate fines and angel hair. Improved water-chamber flow is also said to reduce horsepower demand. The turbulence-free cutting chamber utilizes pressurized process water, which creates a laminar flow in the rotational direction of the cutter blades. The flexible cutter hub utilizes a servo-adjusting mechanism to provide precise bladepressure control against the die face.

The unit also has an electromagnetic clamp and automatic positioning system, which completely automate the pelletizing process. With the push of a button, the cutter hub is brought together by the automatic positioning system. The magnetic clamp is then electrically actuated and completely seals the cutter hub with 1000 lb of clamping force. These features allow one operator to easily activate the pelletizer.

Crown also recently introduced the Ultra Low Impact Belt Dryer. It has a continuous, porous conveyor belt, which transports pellets through one or more drying chambers for low-impact drying. A vacuum-stripper chamber utilizes multiple air knives plus vacuum to strip water from the pellets.

The dryer also features a centrifugal dewatering column. Dewatered pellets exit the column and are deposited on the stainless-steel mesh conveyor. The conveyor belt moves pellets through the vacuum chamber and drying chamber to the outlet port. The unit also is equipped with an “auto clean” cycle for quick clean out and changeover.
