Product Details

Working Principle
Raw materials and excipients are first blended with a binding agent to form a homogeneous mixture. The mixture is then extruded into cylindrical strands through an extrusion module. These strands are fed into a high-speed rotating spheronization plate, where cutting, rotation, and centrifugal forces shape the cylinders into uniform spheres. The resulting micro-pellets exhibit consistent particle size distribution, high mechanical strength, high density, and high yield, achieving a high one-pass qualification rate.

The rotary extrusion module uses a unique low-shear technology, minimizing processing time and limiting temperature rise, making it ideal for heat-sensitive products. Extrusion screens of different pore sizes are available to optimize particle size, surface quality, and uniformity. The spheronizer’s smooth-edged, tightly fitted friction wheels ensure well-formed spherical pellets with consistent size distribution while reducing the generation of fines often encountered in conventional methods.
