Granulation & Pelletizing Equipment and Systems

Centrifugal Pelletizer

Centrifugal pelletizing machine combining granulation and coating processes for converting fine powder materials into granular products

Centrifugal Pelletizer

The centrifugal pelletizer integrates granulation and coating into a single continuous process. Fine powders are introduced into the processing chamber, where a fine mist of binder solution is sprayed to bind the particles together and initiate seed granulation. The resulting seed granules are dried and then reintroduced with additional powder and binder for layering and growth, forming dense, uniformly sized spherical pellets with excellent roundness. By spraying atomized coating liquid onto the finished pellets, a uniform and continuous film layer is formed, making this system ideal for producing coated microgranules and controlled-release pharmaceutical pellets.

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.
