ZYLX Rotary Extrusion–Spheronization Unit

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.

Key Features
Produces uniform, dense, high-strength micro-pellets with high yield.

Low-shear extrusion protects heat-sensitive materials.

Multiple extrusion screen options for tailored particle size and surface quality.

High-speed spheronization ensures smooth, spherical pellets and minimizes fines.

Suitable for various dosage forms, including tablets, capsules, granules, and inhalable powders.

Efficient and reproducible process, suitable for laboratory, pilot, and small-to-medium scale production.
