AEROMATIC-FIELDER - Spheronizer - NICA S700

NICA Spheronizers, model S700

Year of construction: 1998

Developed specifically for the pharmaceutical industry, the NICA Spheronizers S700 from 1998 delivers spherical pellets at fast production rates using patented technology to maximize yields.

Features: 

• Patented 'smooth edge' wheel design 
• Low attrition for maximum yield 
• Reduced spheronization time 
• Interchangeable friction discs for process optimisation 

NICA Spheronizer Process

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. Spaghetti-like extrudates are batched and dropped onto the spinning wheel where they are fractured into short lengths. Interactions between the spinning wheel, the wall and the pellets themselves cause the extrudate to be worked into spheres.

The size distribution and surface 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 Spheronizer has a patented 'smooth edge' on the friction wheel to eliminate 'milling' of the developing pellets, ensuring a narrow size distribution. 

Different friction wheel patterns can be interchanged to suit particular requirements. For continuous production, multiple units can be combined with appropriate up and downstream equipment to form an extremely compact and flexible package (such as the NICA IPS range of integrated pelletizing systems).
