wood pellet production line
The flow path:
Grinding Process——→Drying Process——→Pelleting Process——→Cooling & Sieving Process——→Packing process.
FLOWCHART:
Pelletizing is the process of making waste materials into solid fuel. The pellets are then used for thermal combustion. Wood pellets are one of the most common products of pelletization. biomass pellets can be made from any type of agro-forestry waste: sawdust, wood branches, peanut shells, sugarcane bagasse, caster shells/stalks, sawdust, coffee husks, paddy straw, sunflower stalks, cotton stalks, tobacco waste, mustard stalks, jute waste, bamboo dust, tea waste, wheat straw, palm husks, soybean husks, coconut residues, rice husks, forestry waste, woodchips and other agro-wastes. The moisture content should be less than 12%.
(1).biomass pellet production line---Crushing Process:
When the thickness of the raw wood material is >10 mm, and >50 * 50 mm (L * W), the wood chipper must first be used for size reduction before the feedstock is sent to the hammer mill (crusher) to reach a diameter of less than 3 mm.
(2). Biomass pellet production line---Drying Process:
The best moisture content for pelletizing is about 13-15%. Our rotary dryer can reduce the moisture content from 60% to 10%. The stove may be fueled by sawdust, waste wood, or coal which can save on electricity consumption.

(3). Biomass pellet production line---Pelletizing Process:
RG Wood Pellet Mill,the essence of the complete line, has the following features:
1. The automatic lubrication system for wood pellet mill adopts a tracing and inspection system controlled by a microcomputer. When the temperature of the bearings exceed normal temperatures, the microcomputer will start the auto-lubrication system for lubrication—thereby conveniently ensuring smooth functioning of the rollers. The lubrication system is comprised of a tracing and inspection system controlled by a microcomputer. There is also the option to lubricate by hand.
2. The drive gear is a precision-made transmission mechanism. The bearings are sourced from SKF in Sweden. The ring die uses a hoop fastening method which increases the speed of discharge in comparison with the previous bolt-fastening method. As a result, the capacity is 10-15% higher than the belt transmission structure.
3. The ring die and roller of the wood pellet mill has been finely machined using alloyed steel. The heat treatment process is different from other domestic manufacturers in that the carburization treatment increases the depth of hard-facing to 2 mm which improves the anti-abrasion properties of the ring die and roller by a factor of ten. This greatly saves on replacement costs.
(4). Biomass pellet production line---Cooling Process:
After the pelletizing process, the temperature of the wood pellet is about 60-80 degrees Celsius, with a moisture content of about 15%. A Cooler must then be used to reduce the moisture content of the biomass pellets to about 3-4%, thereby making the wood pellets easier to store.
Suggestion from some clients has suggested that in humid climates, the moisture content must be reduced to 7-8%. In order to satisfy the needs of these clients, we have developed a new Stabilizer Combined Cooler.
(5). Biomass pellet production line---Packing Process:
After cooling, the wood pellet must be protected from moisture and other environmental conditions. For this there is the packing process, which is effectively handled by our Semi-Auto Packing Machine.
Generally, most clients require a small scale with the auto-sealing packing machine and a scale for higher weight ranges for the semi-auto packing machine. For the first, the weight range is 10-45 kgs per bag.
