Automatic Lubricating Biomass Hard Wood Press Mill Machine 3t/h
Biomass Wood press mill is used to make pellets which is a new
green biofuel widely applied in power plant ,civilian heating and
living energy ,industrial boiler .
The raw material fo biomass wood press mill is quite extensive like
agricultural residues ,energy corps ,wood material ,industrial
waste .Sawdust for example ,it is squeezed by wood pelletizing
machine under high temperature becoming into high density pellets
without any chemical additive or binder ,this finished pellet has
advantage of high calorific value ,easy transportation .

How to work of Automatic Lubricating Biomass Hard Wood Press Mill
The material in the granulation bin is fed into the chute by the
feeding auger, the material enters the pressing chamber through the
forced feeder, and is fed into the two pressing areas in the ring
die by the feeding scraper. Due to the high-speed rotation of the
ring die The material is brought between the ring die and the
pressure roller. Under the strong extrusion action of the ring die
and the pressure roller, the material is gradually compacted and
formed in the die hole. Because the extrusion of the material
between the die rollers is continuous , so the formed material is
continuously discharged from the die hole in a columnar shape, and
then cut into particles of the required length by the cutter, and
then enters the next process.
The compression ratio of Biomass Ring Die Pellet Mill
(Compression Ratio= L/D L: Effective Die Hole Pelleting Length; D:
Effective Die Hole Dia)
Generally speaking, the higher the compression ratio, the denser
the finished pellets. But it does not mean that the higher the
compression ratio, the better the pellet quality. Compression ratio
should be calculated based on your raw material for making pellets.
Commonly compression ratio is inversely proportion to the hardness
of raw material, the harder the raw material, the smaller the
compression ratio.
The Spare parts of :Automatic Lubricating Biomass Hard Wood Press Mill
1. Ring die :Pellet dies must resist abrasion, corrosion from chemical
exposure and breakage caused by the physical stresses of pellet
formation. The optimum die combines high resistance to abrasion,
breakage and corrosion with maximum productivity. Our expertise
enables us to precisely match the die specification to your
required formulation, even if it means customizing a die pattern to
meet your exact needs.
2. Roller shell :
Each die and roller assembly stay together as a unit, extending die
and roller life and enabling easy storage and conversion.
Raw material :alloy steel .
Others such as five piece cover ,o ring ,main shaft etc .
