Professional wood pellet machine production line used in urban forestry

Brief introduction of wood pellet machine production line

wood pellet machine production line is a kind of biomass energy pretreatment equipment. The main raw materials are wood chips, straw, rice husk, bark and other biomass from agricultural and forestry processing, which are solidified into high-density granular fuels through pretreatment and processing. wood pellet machine production line is divided into flat-model biomass granulator and Ring-Model biomass granulator.

Due to the different raw materials used in different places, the wood pellet machine production line is also called wood pellet machine, straw pellet machine, sawdust particle machine, wood pellet machine, bamboo pellet machine, fuel pellet machine, straw pellet machine, rice husk pellet machine, etc. in different places. Also known as granulators, although they are called differently, they are all the same machine.

Advantage of wood pellet machine production line

With the combined treatment of energy and environment in China, straw fuel (i.e. biofuel) is a kind of small rod solid granular fuel, which uses solid wastes such as corn stalk, wheat straw, rice straw, peanut hull, corn cob, cotton stalk, soybean stalk, weeds, branches, leaves, sawdust, bark and so on as raw materials and is crushed, pressurized, densified and shaped. Pellet fuel is produced by extruding wood chips, straw and other raw materials with rollers and ring dies at room temperature. The density of raw materials is generally about 0.6-0.8, and the density of formed particles is more than 1.1. It is very convenient to transport and store. At the same time, its combustion performance is greatly improved, reducing human dependence on petrochemical energy and atmospheric emissions.

 Rational utilization of wood pellet machine production line

Biomass fuel is a kind of small rod solid granular fuel, which is made of solid waste such as corn stalk, wheat straw, rice straw, peanut hull, corn cob, cotton stalk, soybean stalk, grain hull, weeds, branches, leaves, sawdust, bark and so on. Pellet fuel is produced by extruding wood chips, straw and other raw materials with rollers and ring dies at room temperature. The density of raw materials is generally about 0.6-0.8. The density of formed particles is more than 1.1. It is very convenient to transport and store. At the same time, its combustion performance has been greatly improved, which has brought some employment problems and economic benefits.

Technological process of wood pellet machine production line

Collection of agricultural and forestry raw materials crushing of raw materials drying of raw materials granulation and shaping cooling screening bagging. 

Fuel characteristics and usage of wood pellet machine production line

Characteristic of biofuels; Formed pellet fuel, with large proportion, small volume, combustibility, easy storage and transportation. The density after moulding is 1.1-1.5. The calorific value can reach 3400-4800 calories. It is a solid fuel with high volatile content and low sulfur content.

 The pellet fuel is a new type of bio-energy. It can replace wood, raw coal, fuel oil, liquefied gas, etc. It is widely used in heating, domestic stoves, hot water boilers, industrial boilers, biomass power plants and so on.

Main uses

1. Civil heating and household energy: high fuel utilization rate, easy storage;

2. Biomass industrial boilers: as the main fuel of industrial boilers, they can replace coal combustion and reduce atmospheric emissions and pollution.

3. Power generation: It can be used as fuel for thermal power generation.
