Die and Roller in Pelletiser

Pelletiser is the heart of the production of wood pellets. The quality and quantity of products of wood pellets is mainly determined by this equipmnent. Quality equipment of pelletiser itself is determined by the ability to produce wood pellets according to specifications or international standards. More and more product of wood pellets are produced or the longer lifespan (life) of pelletiser it indicates good quality. After going through the boundary of the capacity or useful life of the pelletiser to be replaced because it is no longer effective when continuously used. As a benchmark cost for this pelletiser range from Rp 40-75, -/kg wood pellets, including good category.

Pelletiser which is the principle of compression or suppression of material by the roller into the mold (die) to form wood pellets. The high friction on the roller and die on the raw materials and the heat causes the temperature of the metal wear faster. The greater the friction the more dense wood pellet produced  or hard but metal material of pelletiser wear faster. The quality of the metal material in the die and roller of pelletiser and pelletiser design itself contributes greatly to the performance and life of the pelletiser.

Currently there are two kinds pelletiser commonly used in the production process of wood pellet flat die and ring die. The flat die design simpler, commonly used for woodpellet production in small capacity, its history  adopted from animal feed pellet machine. While the type of ring die is a more advanced design, the technique of making it more difficult than further development of the type flat die and commonly used  in production of wood pellets medium-large scale.
