Advantages of biomass pellets :
- Made from waste wood and straw , wide variety of sources .
- New energy , protect the environment .
- High calorific value , ideal energy .
- Make potash fertilizer after burning to impove efficiency .
Main machines used : Wood pellet mills , Drum type wood chipper ,
Hammer mill , Rotatry drum type drying machine, counterlflow cooler
, Automatic packing system .
1. Wood chipping section :
To make the wood into chips with less than 5cm . Drum type wood
chipper is an ideal equipment to produce large capacity wood chips
. The uniquely designed presure reducing device ensures the
long-term stable operation of the equipment .
2. Crushing section :
The wood crushing system can make wood chips into wood sawdust. The
hammer mill is applied mainly to grind the raw materials to make it
suitable to make pellets . The impeller variable frequency feeder
is used to ensure work efficiency .
3. Drying section :
The rotatry drum dryer is designed to reduce the moisture of the
unqualitified raw material , for which the mositure is too high .
the moisture will be from 50% reduce to 15-18% . Burning stove to
supply hot air to drum dryer .
4. Pelleting section :
This is the core equipment of the production line . Used to make
wood sawdust into pellets . The more wear-resistant 42CrMo ring die
is used to produce wood pellets with a high compression ratio .
5. Cooling section :
To cool the pellets to room temperature and remove the moisture in
the pellets , The hardness of the pellets will become stronger . So
as to obtain better hardness and strength . It can also improve
transportaion capacity and storage capacity .
6. Packing section :
The pellets are packed into plastic bag from 10kg-100kg . then use
the thermoplastic sealing machine to sew . these can make the
pellets dry and water-proof . To extend the wood pellets storage
time .
Application of Biomass pellets :
Biomass pellets are made by recycling waste and are a new type of
environmentally friendly fuel , widely used in residential heating
equipment , power plants , boiler plants . etc. It has the
characteristics of large heat generation , low ash content , low
enviromental pollution, and recyclablility .
Commly used in Fireplace , biomass power plant , boiler fuel ,
Household biomass stove .
The advantages of Zhongdebao wood granulator machine's ring die ?
The ring die is the core coponent of the pellet machine ,and the
quality of the ring die affects the life of the pellet machine .
- The ring die of the Zhongdebao biomass pellet machine is made of
42CrMo , which is more wear-resistant and durable than ordineary
alloy steel or carbon steel ring die .
- The special surface carburizing treatment increases the surface
hardness of the ring die and significantly improves the service
life .
- Compressed step release hole is adopted to ensure that the material
enters teh die hole smoothly .
- The high hole opening rate of ring die to ensure the continuous
high output of the plellet machine .
This vertical ring die pellet machine have these models :
