The moisture content of raw materials plays an important role in the briquetting process, it decides the quality of finished products directly. Therefore, it is quite necessary to know the moisture content of materials and how it influences the briquetting process before making briquettes with biomass briquette machine.
The percentage of moisture in the feed biomass to extruder machine is a very critical factor. In general, it has been found that when the feed moisture content is 8-10%, the moisture content of briquettes will be 6-8%. At this moisture content, the briquettes are strong and free of cracks and the process is smooth. But when the moisture content is more than 10%, the briquettes are poor and weak and the operation is erratic. Excess steam is produced at higher moisture content leading to the blockage of incoming feed from the hopper, and sometimes it shoots out the briquettes from the die. Therefore, it is necessary to maintain optimum moisture content.
In the process water also acts as a film type binder by strengthening the bonding in briquettes. In the case of organic and cellular products, water helps in promoting bonding by increasing the true area of contact of the particles. In fact, the surface effects of water are so pronounced that the success or failure of the compaction process solely depends upon the moisture content of the material. The right amount of moisture develops self-bonding properties in lignocelluloses substances at elevated temperatures and pressures prevalent in machines. It is important to establish the initial moisture content of the biomass feed so that the briquettes produced have moisture content greater than the equilibrium value, otherwise the briquettes may swell during storage and transportation and disintegrate when exposed to humid atmospheric conditions.
