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 :
