Wood scraps to make biomass pellets

Wood waste has many types such as: boards, wood blocks, wood chips, scraps, leftovers, decorative boards, twigs, twigs, trunks, building molds, etc… We can process Treating these waste wood materials and reusing them, can effectively reduce the waste of wood resources, and is very helpful for environmental protection.

Wood materials are a renewable biological resource and the only renewable and recyclable green and biological resource among the four main materials (steel, cement, wood and plastic) in the world. Currently. Currently, the recycling of scrap wood scrap is mainly used in the following fields:

1. Waste wood can be used to make paper. Raw materials for paper processing are created from the crushing process, which not only helps to reuse waste wood but also brings economic value. This is a very good wood waste solution, which saves wood resources and protects the surrounding environment.

2. Use waste wood to make wooden panels. Such as particle board, medium fiber board, gypsum particle board, cement particle board, etc.

3. Use waste wood to make handicrafts. Wood is often made into art by craft lovers.

4. Use wood waste to make wood pellets, charcoal, wood vinegar and wood gas.

Advantages of using wood scraps as fuel pellets

Wood scrap is an ideal raw material for making pellets with great economic and social value. The following introduces the advantages of using wood scraps as pellets:

1. Material advantage. In large wood factories, furniture factories, garden yards and enterprises related to the wood industry, a large amount of surplus wood will be produced. These leftover materials are so large and cheap that they were often piled up and corroded directly, or buried or burned, which is also a serious waste of wood resources.

2. High fuel value particles. The fuel value of processed wood pellets can reach 4,500 kcal/kg. Compared with coal, the fire point is low and easy to catch fire; The density is increased and the energy density is high.

3. Fewer harmful particles. When burned, the content of harmful gas components is extremely low, and the emission of harmful gases is also less, which has the effect of protecting the environment. In addition, burning ash can also be used directly as potash fertilizer, which is very cost-effective. In addition, there is very little ash after burning, which greatly reduces the place where coal is piled up and reduces the cost of ballast.

4. Low cost of transporting pellets. Because of the particle shape, the volume is compacted, saving storage space, convenient transportation, reducing transportation costs.

Technology of processing wood scrap to make pellets

Raw material granulation standard: fineness is less than 8mm, moisture content is about 15%

Crushing sieve drying hydraulic collecting barrel hydraulic fine powder collection barrel granulating cooling ton packing dust removal

The processing technology of the granules can be customized according to customer requirements.

Screening: The large wood material is screened out and ground again, the fine material is put into the dryer for drying;

Drying: Wood chips are dried by rotary drum dryer, the drying rate is reduced to 10% -15%;

Hydraulic silo: dried coarse powder into silo to wait for fine powder;

Fine powder: the material is further ground by a high-performance mill to meet the requirements of granulation;

Hydraulic silo: the crushed material enters the silo and waits for granulation;

Granulating: According to different output, one or more high efficiency centrifugal granulators can be equipped for granulation;

Cooling: The temperature of pellets from the pelletizer is above 90 degrees and needs to be cooled down before they can be packed;

Packing: It can be equipped with ton bag scale and granule packing scale.

Dust removal: A large amount of dust will be generated during the grinding, drying, granulation of raw materials, which not only harms workers, but also damages the machine. According to local environmental protection requirements, self-contained production and a total dust removal system can be applied.

Issues to pay attention to in wood pellet processing:

1. Before the worker gets on the machine, the operator must carefully read the manual and understand the various technological processes of the equipment.

2. In the production process, follow the correct operating procedures and orders, and perform installation operations at the request of the unit.

3. Host units should be installed and fixed on a flat concrete floor and secured with screws.

4. Place of production and open flame.

5. After each boot, you need to idling first. After the device is working properly and there is no abnormal condition, you can import together.

6. Other materials are added to the feeder to granulate hard objects such as rocks and metals, then scrap metal is removed to form a screen.

7. During the operation of the equipment, if the material is moved by hand or other tools, it is dangerous.

8. If abnormal sound occurs during production, the power supply must be immediately cut off and production resumed if abnormal conditions occur.

9. Before stopping the machine, you need to stop the feed first. After the raw material processing of the feed system is fully produced, the power supply can be cut off.

Operating the pellet machine exactly as required and paying attention to related issues as required, this can increase the output and operational efficiency of the equipment, and prolong the life of the equipment.
