How Does Pellet Form Its Shape?
You want to produce pellets by pellet mills, you may wonder how does pellet form its shape. Weikeer will tell you the truth
1.The Basic Theory
Inside the ring die of pellet mill, there is double roller shells mounted on an eccentric, turn on a rotating shaft as friction develops. The mutual pressure between ring die and roller shells overcomes the resistance when feed is forced through the die holes in high speed so that dissections of finished pellets become tight layers of feed mixture. The die is driven by a motor and the roller shell turn only as feed between rolls and pellet press dies develops friction.
2. Roller Shells
Because there is friction, so we can see roller shells operate in extremely harsh conditions. Massive forces are transferred from the die face through the bearings to the roll support shaft. The friction causes fatigue crack on the surface. During production, the fatigue crack occurs in a certain depth later, service life of the shell will be longer accordingly.
The life of roller shell is so critical for frequently changing roller shells will also damage the ring die. Which means the material of roller shell should also be got into consideration in purchasing pelleting equipments. Material of Chrome Steel Alloys is advisable for it has good property of fatigue resistance, which suits the requirement of operating in harsh environment.
A good roller shells is not only made of good material, but also match the excellent performance of its dies. Each die and roller assembly stay together as a unit, extending die and roller life and enabling easy storage and conversion.
Why We Need Spare Parts And Why Choose Us ?
Maintenance is necessary for every machine after working a period of time. Pellet mill roller shell is one of the primary working components for pellet mill, used to process different kinds of biomass pellet fuel, feed pellet, wood pellet and so on.
