Large Capacity Biomass Spent Coffee Pellet Making Machine 200kw
Spent Coffee Pellet Press
Biomass Spent Coffee grounds are a renewable resource and can be
recycled after granulation.They are the solid residue left after
coffee beans are ground and brewed , making the spent coffee
grounds that can get profit in waste .
To make Biomass Spent Coffee Pellet , the request for the raw
materials :
1. the moisture <=20%
2. the size is <10mm
If can not get we can provide total proposal .
Brife Introduction of Biomass Spent Coffee Pellet :
- The pelletizing chamber temperatue of the coffee ground pellet
machine is controlled at 90°C by utilizing aerodynamics technology,
so that the machine can operate continuously.
- There is a timing feeder to control the feeding amount in order to
reduce material blockage.
- The machine body of ring die pellet mill is Stainless steel more
durable to use than those from many other suppliers because it is
made from ductile iron.
- It is driven by high precision gears.
- Users do not have to stop the pellet machine to lubricate it.
- This type of commercial pellet mill is controlled by PLC system,
which makes it convenient to operate and saves labor cost.
- The power consumption is 30% less than those from other
manufacturers.
- All the transmission parts of the pellet mill adopt high quality
imported bearings and oil seals to guarantee high efficiency
transmission, stability and low noise.

How to work of Biomass Spent Coffee Pellet
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 Spent Coffee Pellet
(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 Biomass Spent Coffee Pellet
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 .
Why chooseing us :
1. large CNC die drilling center
2. Pellet mill machine assembly and testing center
3. Large embryo forging base
4. Auxiliary manufacturing base and pellet production test center
