Effect of species, particle size and compacting pressure on briquette making machine

Densification of biomass waste materials has provided a great boost to the utilization of wood and agricultural waste for domestic and industrial fuel. However, the processes involved in the production of this fuel make it more expensive than fossil fuel. This is because densification of wood waste into fuel briquettes is not simple. The research found that the effect of species, particle size and compacting pressure on relaxed density and compressive strength affect the performance of biomass briquette making machine greatly.

As for the species of material, the hardwood and soft wood have different density, so the finished products of them are varied in density. The hardwood has high density and the thermal value is higher than the soft wood material. While the softwood materials are difficult to compress into briquette by the briquette making machine. Under the same condition, the hardwood has good performance in the briquetting process and consumption effect. As for the crop straw and other biomass material, the density is lower than the wood material in general. And it is difficult for them to briquetting by the briquette making machine.
 
Particle size plays an important role to the briquette making machine. The agriculture waste or forest waste are different in shape and size, which are disadvantages to the briquetting process. As for the features of the waste residues, the hammer mill or the debarking machine is used to reduce the particle size of the material. It can increase the contact surface of the particles which strengthen the combing force between them. So the briquette has high density. At the same time, the briquette has high thermal value with less ash content and waste air.
 
Compressive pressure is the key point of the briquetting process. The quality of finished products is greatly decided upon the briquetting process. And a good quality briquette making machine can compress the material well no matter what kind of material for briquetting. Compressive pressure is the heart technology of the biomass briquette making machine. While the pressure come form the durable wear parts, scientific design of the structure and the proper adjustment of the briquette making machine. In addition, an experienced operator has good knowledge of the technology is a plus of the briquetting process success. The bigger the pressure is, the lignin content contained in the biomass material is more reliable to come out to combine the relaxed material. But the biggest pressure can damage the briquetting machine sometimes, if the pressure is beyond the wearing resistance of the wear parts. Of course, too small of the pressure give rise to the failure of the briquetting or the finished products are lower in density which are easy to break during transportation.
 
Of course, briquetting technology is a complicated process for different material. For good quality briquette, many related elements should be considered. On the basis of the combination of adjustment of species, pressure and particle size, we have to pay attention the drying process, cooling process and the sifting process. Actually, a good quality biomass briquetting making machine merely provides a foundation for the making briquette. Of course, the three elements give you a chance to making high quality briquette if you mastering the adjustment skills. KMEC is a professional provider of briquette making machine.
