The key of an efficient pelleting process is to determine the optimal compromise between energy consumption and pellet quality, while producing the desired capacity. The pelleting process is influenced by many factors, from steam addition to Pellet mill settings and motor load.

Enhancing Gelatinization for Optimal Pelleting Performance

By adding more steam, gelatinization is improved and the meal can be pelleted better. This results in a higher capacity, improved quality and less energy consumption. There is a limit to the quantity of steam that can be added as too much steam addition can cause roller slip and lead to downtime by the mill becoming blocked.

Precision in Pellet Quality: Roller Gap Distance and Mechanical Energy

By increasing the roller gap distance to the die, a higher quality can be realized because more pressure (mechanical energy) is applied. This will however have a negative effect on capacity and energy consumption as more power is needed to force the meal through the die. The same effect can be achieved by changing to a die with a larger die thickness.

What if…

Explore the possibilities of the Van Aarsen pelleting technology.

Animal feed pellets can be produced in several diameters and hardness, by pelletizing raw materials after grinding, mixing, and conditioning. The Van Aarsen C and CU pellet mill range enable capacities up to 70 tons per hour depending on various parameters. They offer low operational costs per ton feed, even down to 1 €/ton, including dies, rollers and wear parts.
