The NICA™ S450 is designed for both product development purposes and small scale production of spherical pellets from extrudate.

Principles of Operation
The NICA™ Spheronizer consists of a horizontal spinning wheel with a special friction pattern machined on its top surface; it rotates within a cylindrical bowl. The spaghetti-like extrudates are batched and dropped onto the spinning wheel where they are fractured into short lengths. Interaction between the spinning wheel and the wall causes the extrudate to be worked into spheres. The size distribution and suface characteristics of the spheres are controlled by the batch size, speed, process time and most importantly, by the characteristics of the extruded mass. The NICA™ 450 Spheronizer has a patented 'smooth edge' on the friction wheel to eliminate milling of the developing pellets and ensure a narrow size distribution. Different friction whell patterns can be interchanged to suit particular requirements. For continuous production, multiple units can be combined with appropriate up and downstream equipment forming an extremely compact and flexible package.
