Pelleting Machines, Basket Extruders and Spheronizers

Extrusion is understood as low pressure extrusion for the production of slightly dispersed dust-free granulates.

If cylindrical granulates are achieved, a process using the Gear Pelletizer comes into use. Typically granulates of 1 to 10 mm diameter are produced. In the Gear Pelletizer the extrusion takes place by a pair of counter rotating hollow toothed rollers.

For shingled, highly porous granulates with good dispersal properties the Bextruder is used. With the Bextruder the material is compressed with an extrusion rotor with a perforating die.

The rounding off of pellets is known as spheronisation. This process is often used after an extrusion process in which soft granulate is produced with the Bexroller.

Gear Pelletizer

With the Gear Pelletizer cylindrical, stable pellets with uniform length are formed.

Bextruder

With the Bextruder the product is gently pressed to granulate with a loose structure and large surface area.

Bexroller

With the Bexroller pellets are rounded off. The rounding process is known as spheronisation.
