 How Does Pellet Form Its Shape?

You want to produce pellets by pellet mills, you may wonder how does pellet form its shape.FDSP 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.

Different Patterns Of Roller Shell

Roller shell is the surface of roller assembly where raw materials are pressed against the die. It can be used on pellet machine to make various kinds of feed pellets, fuel pellets or other kinds of pellets.

There are many types of roller shell, such as Open Ends Corrugated, Closed Ends Corrugated, Dimpled and oblique shaped roller shell, honeycomb shaped,scallop shaped,fluted shaped etc. Corrugated roller shell and dimpled roller shell are the mostly used types in the livestock and poultry feed pelleting and biomass pelleting industry.

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.

We are a professional manufacturer specialized in roller shells and other pellet mill spare parts like ring die ,bearings, shafts and so on with about 20 years experiences. Our roller shells enjoy high abrasion resistance and corrosion resistance, which make sure roller shells get long service life.

Our roll shells and other pellet machine spare parts can be used either in feed pelleting industry to produce animal feeds or fuel pelleting industry to produce wood pellets. We use good quality bearing steel, alloy steel or carbon steel to make roller shell. The roller shell working areas ranges from 60mm to 300mm, the diameter of the pellet roll/shell ranges from 110mm to 450mm, the hardness reaches at HRC58-62.

I.D. = Inner Diameter of Roller Shell: inside diameter is the most common identified dimension of a pellet roll shell and is always specified during the die selection.

O.D. = Overall Diameter of Roller Shell: The diameter of the pellet roll/shell 

W = Width of Roller Shell

Our ring dies and roller shells are well sold all over the world, We can also make all kinds of pellet mill roller shells as per customers' drawing. We have every part you need to keep your equipment running smoothly.
