Optimization The Pelletiser Perfomance

Carpet is a thin layer of material that is pressed, which are at the peak of the die surface. When the incoming raw materials into pelletiser it will be driven by the roller and forming carpet. The more materials put into pelletiser it will further add to the carpet. Carpet is then pressed into the die holes and produce pellets. So for material that can form a pellet, initially to be able to form a carpet.

All wood pellet production is a matter of reducing energy requirements and the degree of wear of equipment while simultaneously improving quality and productivity of the pellets. This is why the production of quality pellets require special skills. Setting between roller and die with a certain distance which is called the roller gap that is essential for the above purpose. Characteristics of raw materials such as density and bonding ability are other parameters that need to be considered. Roller gap can be set at a certain distance so that the pelletiser performance will optimal. Generally, gap 1 mm is the optimum condition, but the gap variation can be tried for the specific conditions of certain raw materials.

On hole die if we look deeper , it turns out is also not a form of cylindrical holes from the tip to the hilt . These conditions also deliberately designed so that the densification process can be optimal . If the shape of the tip is widened at the inlet of the die wear and missing then the quality of pellets produced will decline even not formed pellets . Comparison of length ( L ) and diameter ( D ) on the die hole according to the characteristics of raw materials will result in optimal performance . Selection of an appropriate metal material will make the pelleting process can be done economically . The quality of metal and metal working to die makes no domestic manufacturers are making in Indonesia. Another factor in has not many wood pellet producers in Indonesia may also be a factor in the reluctance of domestic manufacturers to make dies for wood / biomass pellets. But as the needs of wood pellet or pellet fuel increasingly skyrocketing then the above is possible.
