Small Scale 500-700 KG/H Biomass Wood Pellet Production Line

Richi machinery small scale good quality 500-700 kg/h biomass wood pellet production line is specially designed for all manufacturers based on the principle of biomass recycling, such as biomass fuel manufacturers, wood board plants, organic fertilizer plants, feed plants, carton plants, etc. The main processing flow of 500-700 kg/h biomass wood pellet production line: raw material crushing, drying, pelletizing, cooling, screening, packaging. The main equipment of a complete 500-700 kg/h biomass wood pellet mill plant includes wood chipper machine, wood hammer mill crusher, drum rotary dryer, wood pellet mill machine, counter-flow cooler, vibrating screen classifier, automatic bagging system, electric control cabinet, etc.

Raw Materials of Biomass Wood Pellet Production Line

Animal manure: mixture of poultry litter and animal waste, such as the wastes of slaughterhouse, fish market, urine and dung of cattle, pigs, sheep, chicken, ducks, geese, goat, etc.
Forestry waste: wood, logs, wood chips, branches, leaves, roots, bark, sawdust, bamboo, bamboo chips, timber slash, mill scrap and other forest residues and waste wood.
Plant: grass, hay, alfalfa, lucerne, elephant grass, miscanthus, hemp, hops, etc.
Agricultural waste: cotton stalks, cotton husks, corn stalks, soybean stalks, wheat stalks, sunflower trays, sunflower husks, rice husks, bagasse, olive pomace, peanut husks, peanut seedlings, rice bran, etc.
Home scrap: food waste, the roots and leaves of vegetables, etc.
Industrial waste: wine lees, vinegar residue, manioc waste, sugar scum, silica fume, furfural residue, etc.
Sludge: The sludge that can be pelletized mainly comes from paper mills, Slaughterhouse, live-stock, rubber, landfill leachate, dairy, brewery, textile and other effluents.

How to Make Biomass Wood Pellet?

Process of Complete Wood Biomass Pellet Production Line

Wood biomass pellets can be made from sawdust, wood shavings, wood chips or wood logs, any forestry wastes or biomass straws, stalks, etc.
Crushing machine is used for crushing the larger materials into smaller powder for supporting produce wood pellets. Wood crusher is ideal equipment for crushing raw materials like square logs with diameter less than 200mm; if the material has a diameter less than 50mm, then wood hammer mill is the best choice. The best thickness of the wood chip is less 5mm. After milled, the output size can reach diameter 3-5 mm,which is convenient for further processing to get dried and pelletized.
The best moisture content to pelletizing is about 11-17%. So before pelletizing, a drying machine is needed to make the moisture content reaches the required standards.
Pellet mill is the significant part of the wood pellet production line, and has reliable and stable performance. Capacity ranges from 1T to 10T per hour. You can choose ring die pellet mill or flat die pellet mill depend on your capacity requirements.
After pelletizing process, the temperature of wood biomass pellets is between 60-80 degrees and the moisture content is close to 15%. So a cooler must be used to reduce their surface temperat

Application

1) As biomass fuel

Biomass pellets as fuels are usually burning at pellet boilers, pellet stoves and other pellet appliance at household. While large scale biomass pellets usually co-fires with traditional fuels, such as coals, oil and others, at large scale boilers or power plant or factory, etc.

2) As animal feed

Biomass straw grass pellets can be good pellet fodder for animals. Comparing with biomass, the biomass pellets fodders has the advantages of cleanness, balance nutrition, easy to store and longer quality guarantee period.

3) As animal bedding

Beside being used as fuel and animal fodders, biomass pellets can also be used as animal bedding, such as horse bedding, cat litter, etc. biomass pellets used as animal bedding are popular for biomass pellets are , natural products without additives and of high hygienic, they are the best products for animal bedding.
