Wood pallet is a type of fuel that is made from compacted sawdust and related industrial wastes from the milling of wood, manufacture of wood products, and furniture. Wood pellets are manufactured by pellet plants and available in bags for sale for both commercials as well as personal use. If you want to make use of a Wood Log to Sawdust Making, contact wood log dealers.
Raw material preparation
Preparing raw material is the first thing when we make wood pellets. In order to make a small wood pellet plant, the quantity of raw material is not much. If you want to make wood pellet for personal use, the raw material is normally the crop waste in the farmland. And for commercial use, the raw materials are the wood shaving collected from a saw mill nearby. The large wood pellet plant on the other side faces major problems regarding the preparation of raw material.
Initial size-reduction
The first thing that has to be done for a large pellet plant is reducing the size of raw material when raw materials are ready. The diameter of the raw materials to produce wood pellets must be under the diameter of 5mm so that the logs and branches should be cut into small pieces.
Drying
After reducing the size of raw material the next step is to dry the raw materials. The raw materials must maintain moisture 8 to 12% to get a high-quality wood pellet. Therefore the raw material must be put into a dryer to reduce its moisture content. A rotary drum dryer is considered the most cost-effective choice for a large pellet plant. This step is also essential for a small-scale pellet plant to produce commercial wood pellets.
Grinding
This is also a type of size reduction step to make wood pellets, and it is an essential step for small as well as large pellet plants. The raw material is put into a hammer mill which will grind them into small pieces having a diameter under 5 mm.
Pelletizing
Pellet mill is the name of the machine which is used to pelletize the raw material into the wood pellet. And this is of two types, ring die pellet mill is used for large plant having capacity 1ton per hour while the other flat die pellet mill which is used for small plat having a capacity of 500kg per hour.
Cooling
After the pelletizing process, the wood pellet will be fed into a pellet cooler so that it can regain its rigidity and temperature. There are three kinds of pellet cooler, horizontal cooler, vertical cooler, and counter flow cooler. All of them can be used for cooling purposes but the counter flow cooler is the most advanced pellet cooler in the market.
Final sieving
This step only exists in the commercial wood pellet plant as the commercial wood pellet has a strict limit on content after the pellet cooling process, the wood pellet products will be sieved to separate the fine particles from the proper-made wood pellet.
Conclusion
The wood pellet manufacture process is different in real pellet plants and this is due to its different utilization. So this is the complete guide on how to make sawdust from the wood log. Usually, the use of Wood Log to Sawdust Making is on-demand these days.
