beautiful shape,pellet mill:6-12mm
1.pellet machine
This equipment is popular in granulating agricultural residues and forestry residues to forming pellets, which can be used as bio-fuel for bio-energy industry, such as biomass-fire powered boiler. The advancement of our product as follows
1)
feed device for feedstock is specially designed, so that can keep feeding smoothly, also, you can adjust the feeding speed.
2)
Transport device we choose advanced gear box, which can improve more than 15% capacity of production.
3)
Main bearing we purchase imported high character bearing. Make sure its high effective, high stable and high reliable.
4)
One of the important parts ring die whose material is stainless steel and alloy steel we fabricated with advanced technical process. In this case, we can promise its long service life, smooth enough for granulating and high qulity.
5)
Transport equipment we purchase siemens motors which can provide continuously powerful power.
Parameter of our product
420 type main power: 90kw capacity :0.8-1.5t/h
508 type main power :132kw capacity :1.5-2t/h
2. spares
1)main bearing the technique of forging process for main bearing of granulator is specially designed, which is especially for the high strength alloy steel. As a result, our main bearing have a good character in bending resistance and anti-torque.
2)race-rotation material use high strength alloy steel, make sure its long term for stable and smooth operation.
3)gear:
material use high quality alloy steel, and be grinded smoothly by advanced grinding process. So we can promise its running in good condition, smoothly, little noise and have a long service time.
4)pressure roller it is different from the common press roller. Our press rollers are made of high quality rall bearing steel, so they have good hardness, against wearing and tearing. According to the difference of feedstock, we can choose different type of press roller.
5)ring die: material is high quality alloy steel and stainless steel. Use advanced technique process to forging it. The holes of the die is drilled by import driller at the same time. the surface of the hole is very smooth which can make sure the nice visual and good character of the pellets. In conclusion, our ring die has a long service life and can help to improving the production capacity.
3 the pendulous cooler


We have reflow theory for the condenser, which can sufficiently cool the pellets
The slide valve type discharge device is specially designed.
The discharge device can keep operating stably and discharging smoothly.
The temperature of pellets that cooled down is no more than 3-5 degree Celsius compared to room temperature.

4.feedstock sieving device

Instruction detail
Diameter 1000-2500mm Single power 1.5kw
It is used to separating original residues to getting biomass fuel feedstock.
The design is uncomplicated, operation is easy and comfortable, little noisy for function.
5. Drying device of


Advancement of our dryer
1.
simple construction for which have less spares for transmission device. It has little chance for breakdown, so our product can reduce the cost of maintenance and construction.
2.
it improves the pellets’ surface area of dryness and the effectivity of heating transfer
3.
continuously feeding for feedstock and power supplying
4.
high capacity



6. miller device

Whatever the size of pellets, the second mill tool in mill space can improve the production capacity up to 15%.
Two small gap between mixing space and sieving space is used to do the rough grinding and final grinding separately.
This equipment can mill all kinds of biomass feedstock
Technique parameter
7.belt type conveyor

1.belt is driven by powerful electrical motor.
2.the material of belt is mainly like nylon. The support of the belt is made of aluminium alloy, painted steel and stainless steel as you like.
3.the conveyor have the advancement for high effectivity and easy maintenance.
8.sample of bio-fuel pellets

The bio-fuel pellets are granulated at room temperature with high pressure that depending on the rotation of the ring die around the roller. The feedstock of pellets usually is wood sawdust, straw and something else. The original density of these feedstock normally is 130kg/m3, but after granulating the density can improve up to 1100kg/m3. it is very convenience for transporting and storing these pellets , at the same time, the heating value of pellets are largely improved compared to original feedstock.
production process
1.
pick up feedstock. 2.mill feedstock.3.granulate feedstock to pellets.4package pellets
2.
according to the different harvest time of different agriculture, we should timely pick up feedstock as much as we can, than make them to bio-fuel pellets in time.
3.
one thing we should pay attention to is we should not immediately package up the pellets until them cooled down 40 minutes later, because the pellets will be expanded when heated up, in contrast, they will be contracted when cooled down ect.
