Deflective Grooved Roller Shell

Features:

*The service life is based on Sinova’s R&D Lab data. The actual life is decided by several factors such as operation level, raw material quality,
formula composition etc.

Why Sinova:

Advantages:

High quality raw material

40Cr/60Si2Mn/20CrMn/GCr15 alloy steel, tempered to 60-65HRC, is adopted to meet the demand of high grade roller shell. All the raw materials are from one of the biggest forging companies in Asia.

Shorter lead time

Plenty of automatic CNC machines, automatic lathes and milling machines, ensure most of the processing could be conducted in unmanned mode. Sinova factory is still expanding year by year.

FAQ:

1.Q: What is pellet mill?

A: A pellet mill, also known as a pellet press, is a type of mill or machine press used to
create pellets from powdered material. Pellet mills are unlike grinding mills, in that they combine small materials into a larger, homogeneous mass, rather than break large materials into smaller pieces.

There are many types of pellet mills that can be generally grouped into large-scale and small-scale types. According to the production capacity, pellet mills also can be divided into flat die
pellet mill and ring die pellet mill.

There are two common types of large-scale pellet mills: flat die mills and ring die mills. Flat die mills use a flat die with slots. The powder is introduced to the top of the die and as the die
rotates a roller presses the powder through the holes in the die. A cutter on the other side of the die cuts the exposed pellet free from the die. In the ring die there are radial slot throughout the die. Powder is fed into
the inside of the die and spreaders evenly distribute the powder. Two rollers then compress the powder through the die holes. Two cutters are used to cut the pellets free from the outside of the die.

Large scale pellet mills are usually used to produce animal feed, wood pellets, and fuel pellets for use in a pellet stove.

Small-scale mills are usually variations of screw presses or hydraulic presses. The same basic process is used for both types. A die, also known as a mold, holds the uncompressed powder in a shaped
pocket. The pocket shape defined the final pellet shape. A platen is attached to the end of the screw (in a screw press) or the ram (in a hydraulic press) which compresses the powder.

Some platens are heated to speed up the time it takes and improve the overall structure of the pellet. They may also have water ports for quick cooling
between uses.

2.Q:How long is the service life of roller shell?

A:As per Sinova’s test results, it could service for 400-600hours. The actual life will be decided by several
factors such as operation level, raw material quality, formula etc.
