Roller shell, commonly known as roller, is one of the main parts of pellet mill. It can be used to process various biofuel pellets, animal feed and other pellets.Material: Alloy steel, spring steel and bearing steel.Special thermal treatment ensures better wear resisting, and pelletizing performance.
Now we have the roller shells of different shapes, such as:
closed-end grooved roller shell, honeycombed roller shell, drum-hole groove roller, open-end grooved roller shell, deflective-grooved roller shell etc.
Grooved roller shell
Grooved roller shell: good material intake performance, and is widely applied by feed plants.
Includes thin corrugated and strong corrugated
Normally, for small hole ring die, thin corrugated roller shell shall be applied, while strong corrugated roller shell is applied to large hole ring die.
Grooved roller shell can be divided into open-end and closed-end, closed-end roller shell is good for material discharge from side holes, and increase extrusion force on both sides.
Honeycombed roller shell
Honeycombed roller shell is mainly applied to pelletize poultry feeds. The advantage is that it is uniform wearing，but has bad material intake performance. Large frictional force makes easy polishing.
FDSP can manufacture roller shells of different size and appearance according to your requirements or drawings or samples.
|Open-end grooved type||Closed-end grooved type||Herringbone-grooved type|
|Deflective grooved type||Drum-hole groove type|
|Open-end grooved drum roller||Arc alveolar type|
Honeycomb alveolar compound type
