    • The integrated extrusion–spheronization system combines extrusion and rounding functions within a single, continuous process. Moist granulated material produced by a mixer is fed into the auxiliary hopper at the top of the unit. The screw feeder delivers the material evenly to the vertical extruder, where it is pressed and shaped through a perforated screen into short cylindrical extrudates. These extrudates then fall by gravity into a timed valve chamber, which intermittently transfers batches into the centrifugal spheronizing chamber. Inside, the rotating plate and frictional forces between particles, chamber wall, and airflow ensure consistent rounding, producing smooth, dense, and uniform pellets that are discharged through a pneumatic gate.

    The powder processing and palletizing equipment is widely used in pharmaceutical, food, and chemical applications. Selection can be made based on material type (e.g. wet, dry, or fragile), flowability, and target throughput. Based on these parameters, a suitable model and configuration are recommended for the intended process.

    Our powder handling equipment can be built using high-temperature-resistant, corrosion-resistant, and explosion-proof designs. Typical options include 316L stainless steel construction, PTFE sealing, explosion-proof motors, and nitrogen inerting systems.

    Our powder processing machines are designed in line with GMP requirements. Product-contact surfaces can be supplied in SS304 or SS316L with polished finishes down to Ra ≤ 0.4 μm, suitable for installation in clean production areas.

    Complete lines can be tailored, including equipment footprint, capacity range, and inlet/outlet height, to achieve direct integration into existing processes.

    Voltage and frequency can be supplied according to regional standards (for example 220 V / 380 V / 415 V, 50 Hz / 60 Hz). Control systems can include PLC and HMI with Siemens or Schneider electrical components.
