Granulation Systems

Powder Pelleting Plant

LCI can engineer and provide complete granulation systems which take your product from powder to pellet or sphere, ready for packaging or further processing. These systems are based on the broadest range of extrusion methods available. This flexibility of choice allows our clients to more closely produce the exact granule properties they require.

The Powder Pelleting Process

The Solids Handling Process

1. Feeding

Circle Feeder – Up to 1.9 m3/min (~68 ft3/min)

The Circle Feeder™ is widely known for its ability to prevent material arching, bridging, and ratholing. The Circle Feeder™ can be manufactured with several outlets for “one to multiple” feeding, which saves on equipment, space, and maintenance costs.

2. Kneading

Continuous Kneader – Up to 480 L (~125 gal) working volume

The Continuous Kneader is a counter rotating twin shaft mixer. The Kneader mixes powders and liquids together continuously and homogeneously, making it ideal for continuous downstream processes that require consistent moisture levels. Can be jacketed for heating or cooling applications.

3. Extrusion

Basket Granulator™ - Lowest pressure extruder – Up to 1500 kg/hr (~3305 lb/hr)

Twin Screw Xtruder™ - Radial Configuration – Up to 1200 kg/hr (~2645 lb/hr)

The Extruder transforms the homogeneous wet mass to produce well-formed cylindrical extrudates of a controlled diameter. The extrudates break off by their own weight and are collected for the next processing step. Depending on the desired end product, the wet extrudates will either be spheronized or dried.

4. Drying and Packaging

The wet extrudates (or spheres) exiting the extruder (or spheronizer) are charged to the inlet of a Continuously Vibrating Fluid Bed Dryer. The dried granules (or spheres) are then discharged to sieving and / or packaging.
