Making Briquettes from Sawdust for Fuel Use
Sawdust as FuelBurning wood for fuel has became one of living skill of people since the ancient time, with the development of human beings, people start to burn not only burn the wood but also the residues of wood processing including the wood chippings, shavings, twigs, even, people collect the sawdust produced from the sawing wood to burn as fuel for daily cooking and heating.
Speaking of sawdust, as well all know that sawdust is the by-products produced after the wood processing, which can be the fine powder from sawing the wood, the shavings produced from the timber making. Due to the fine-powder shape, at the early time, people use the sawdust for keeping the flowers and trees warm in winter through putting the sawdust into the root part; use sawdust after fermentation as fertilizer to grow flowers and plants well. While in some places, sawdust with high concentration would be regarded as an environmental problem, because the sawdust is not so easy to discompose, needing a very long time. With combustion, sawdust can release out heat and help people to reduce the daily fuel cost. Therefore, sawdust is widely sued for fuel every day.
Development of Making Briquettes from Sawdust for UseWhen time comes to the modern society, with the increasingly worse and worse air pollution and global warming, people start to realize the bad effects of direct sawdust combustion on the living environment and then begin to research and develop green energy and green energy making technology.
Briquetting technology briquetting machine was born in this proper time. This punching briquetting machine is designed for making briquettes from sawdust. Through briquetting machine, the loose sawdust can be made into high density sawdust briquettes with uniform diameter and length.
|Model||Specification||Density||Main engine power||Output||Dimensions|
|Punching briquetting machine||Diameter 8mm-22mm pellets||Diameter 30mm-70mm briquettes||1000-1300kg/m3||45KW||0.8-1.2 t/h||Main engine 3.4m*2m*1.8m||Main engine 3.4m*2m*1.8m|
Different size of sawdust briquettes have different applications in different countries and regions. Generally, the diameter 8mm-22mm pellet is widely used for BBQ, small home-use stove, home cooking etc; the diameter 30mm-70mm briquette is widely produced for industrial boiler, biomass power generation, especially the 70mm diameter briquette is more suitable for the large industrial boiler, stove etc.
Besides, in the relatively developing countries, people produce the sawdust briquettes and directly sell out around the neighborhood; while in the developed countries, people care the sawdust briquette quality, package and other elements, making briquettes from sawdust becomes a more serious thing, needing more complete processing. Thus, the production for making briquettes from sawdust is suggested to set up.
How to Make High Quality Sawdust Briquettes?
- Sawdust preparation. Due to the strict requirement in the raw material, you should prepare the sawdust well in the aspects of moisture content and size, the moisture content should be kept within 12%to 15%. If the raw material is the wood chipping or shavings, the hammer mill should be equipped as well in making sawdust briquettes.
- After sawdust preparation, briquetting can start. In this processing, the type of briquetting machine should be equipped with the actual situation and final requirements in applications.
- High quality sawdust briquette includes the smooth surface, high density, not easy breaking etc. When the sawdust briquette is produced from the briquetting machine, it should be cooled into the indoor temperature for later better storage.
- At last, after the series processing, sawdust briquette has been produced with perfect features, thus needing good package as well for later selling, auto packing machine is equipped for the final processing.
