Find out how you can optimize your pelleting process with the new generation Van Aarsen pellet mills with motor-operated roller adjustment and active roller slip control. These functionalities provide you optimized operation and the opportunity to experiment with the roller distance and steam addition for the recipes to boost feed quality and production efficiency.

Optimizing your pelleting process

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.

  • 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.
  • 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…

  • your pellet mill allows automatic and recipe controlled roller gap setting
  • blockages caused by roller slip would be eliminated
  • the down time of die blockages due to another overload could be reduced
  • feed quality would be optimized
  • and production efficiency was to be increased

A new generation pellet mills

Adding new functionalities

  • Motor operated roller adjustment
    The motor-operated roller adjustment enables the operator to easily choose the desired roller distance to the die, even when the pellet mill is in full operation. This system offers precise and recipe controlled roller gap settings enabling you to optimize the pellet quality.
  • Active roller slip control
    This system detects roller slip and activates the system to automatically resolve the slip if desired, reducing the downtime of the pellet mill caused by roller slip to nil.It also offers you the opportunity to experiment with the roller distance and steam addition for the recipes to boost feed quality and production efficiency. You can rely on this system while exploring the settings for the most optimum production.

Reduced maintenance costs

  • Longer lifetime of the die and rollers
    Another benefit is the increased life expectancy of the die and rollers up to 30%. By linking the operation of the dosing screw to the roller distance, the rollers will retract when the pellet mill is not producing.
  • Easy die-cleaning mode
    The system is equipped with a die-cleaning mode, enabling the operator to clean the die after a batch. This will also provide a quick start-up of the pellet mill after a standstill, because the product doesn’t get the opportunity to “cake” to the die.
  • Easy-to-clean coating
    All critical components are treated with an easy-to-clean coating.

There is a strong link between our expertise and the quality of your machine

Reduced Total Cost Of Ownership

Real value

The acquisition costs of a machine are just half the truth. The operating costs (maintenance costs, unplanned downtime, change-over costs, energy costs, quality costs, etc.) determine the real investment in your machine. The extra investment of a new CU Dynamic pellet mill compared to a CU Basic pellet mill has a short payback time. Even less than 1 year is realistic.

Upgrade your existing pellet mill

When you are not looking for a new pellet mill but are interested in the additional benefits of the CU Dynamic, it is also possible to upgrade your existing Van Aarsen C-type pellet mill to this new standard. An upgrade is recommended when the current die holder should be replaced, saving revision costs.

Turning cost factors into success factors

Optimizing your pelleting process

Low maintenance, high durability
Less wear and tear – easy adjustment of the roller lever and changing of the rollers – die cleaning mode – easy to clean coating.
New materials – less vibrations sensitive – even longer lifetime


High efficiency, extra capacity
Higher capacity against lower costs – less down time


Energy efficient
Always the ideal settings – rollers retract during empty running – higher motor load and capacity = less kwh per ton feed


User friendly
One touch on the control panel or by feed mill automation


High flexibility
Recipe controlled roller gap setting


High feed quality
Optimal settings for required feed quality – larger roller gap without fear for slip or blockages
