Van Aarsen launches new CU Dynamic pellet mill




Van Aarsen International develops, manufactures and supplies machines and complete production lines for compound feed and premixes worldwide.

Van Aarsen has now launched its CU Dynamic pellet mill with motor-operated roller adjustment and active roller slip control. This means that compound feed manufacturers can always produce exactly the correct pellet quality with one push of a button.

Moreover, with the new CU Dynamic pellet mill, producers can prevent downtime caused by the obstruction of the mill. This can result in a 15% increase in production capacity.

Motor-operated roller adjustment increases pellet quality and production capacity

An optimum constant pellet quality boosts feed intake and animal health. In addition, optimum quality feed pellets means less dust and waste in transport and feeding systems. However, supplying the correct pellet quality is not a constant process and is highly dependent on factors such as desired end quality, production capacity, the recipe used and raw materials.

When producing pellets, setting the correct roller distance to the die is one of the main factors to guarantee correct pellet quality. This is a time-consuming factor that, in practice, calls for several manual actions, a problem which makes implementing the correct setting difficult.

Reduce downtime due to roller slip by 95%

The new CU Dynamic pellet mill is equipped with an active roller slip control system. When the rollers slip and the mill risks overload, the system detects the slip and takes immediate action. The active roller slip control presses the rollers immediately against the die, preventing the rollers from slipping. The meal that is accumulated in front of the roller is milled away. The control system reduces downtime due to roller slip by 95%. If the mill stops due to another overload, the rollers can be retracted by the motor-operated roller adjustment and pressed against the die so that the mill starts up again quickly. The motor-operated adjustment of the rollers can done in the midst of the pellet mill's operation. In combination with the roller slip control, the operator can experiment during the production process with the roller setting to optimise pellet mill load and production capacity.

Reduce wear and die changes

Van Aarsen developed the new CU Dynamic pellet mill with motor-operated roller adjustment specifically for compound feed manufacturers who have to make regular recipe changes.

With this new mill, feed producers can set optimum roller distance to the die with one push of a button.

Due to a link to the factory automation system, selecting the correct roller setting automatically for established recipe settings can be done. This means the recipe can be conveniently changed.

As the mechanical energy factor can also be determined by setting the roller distance, the die (thickness) does not have to be adjusted as often. This also helps reduce downtime. The CU Dynamic pellet mill is equipped with a die cleaning mode so that the operator can clean the die easily whenever he wants. Thus, the meal will not easily cake onto the die, leading to a quick start-up of the pellet mill. As the rollers retract automatically after each product, there is less wear of the die and rollers and their life is increased by up to 30%.

Payback time less than two years

The new CU Dynamic pellet mill by Van Aarsen International from Panheel (the Netherlands) increases flexibility and pellet quality and reduces downtime. This results in an increase in production capacity as well as savings on maintenance and equipment.

When required, existing Van Aarsen mills can be upgraded to the new advanced CU Dynamic.
