Pellet mill specifications

Wood pellets mills are comprised of  a few different parts. The first part may be the feeder, in which the feed enters the pellet mill and is carried along. Then the feed may enter one or more conditioning chamber/s (particularly for feed, especially aquatic feed). Here the feed is treated with steam and could have molasses added.

When the above has been completed, the raw material enters the pelleting chamber. It's here that the material is compressed by roller shells, and is forced through the holes of the pellet die. The raw material is continued to be compressed in the holes, and through the outer side of the pellet die, come out the formed pellet dies. Knives attached to the pellet mill then cut the pellets into predetermined length and also the pelleting process is over with formed, cut pellets decrease the output chute.

If neccessary pellets will then undergo a crumbler, which is positioned underneath the output chute of the pellet mill, the pellet crumbler will crumble the pellets into crumbles. Following the wood pellet mill comes the cooler, which cools the pellets down as the pellets are hot after the pelleting process. Pellets are then sifted and finished pellets are output from the plant, ready for bagging or use.

The wood pellets mill must be sized properly to efficiently handle one's pelleting requirements.

The next application factors need to be determined before proper selection of a wood pellet mill can be made.

a. Types of formulation or ingredients used.

b. Capacity requirements in tons.

c. Pellet quality requirements, i.e., pellet durability index.

d. Product mix -- both required pellet diameter and length of run.
