preventing the rollers slipping and the meal 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 is even possible while the 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 press of a button. Moreover, with the new CU Dynamic pellet mill, producers can prevent downtime caused by the mill becoming blocked. This results 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 systems and feed equipment. 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 milling the correct pellet, 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 so many manual actions that correct setting is almost impossible.


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 threatens to become full, the system detects the slip and takes immediate action. The active roller slip control presses the rollers immediately against the die,

is in operation. In combination with the roller slip control, the operator can experiment during the production process with the correct roller adjustment 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 especially 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 press of a button. Thanks to a link to the factory automation system it is possible to select the correct roller setting automatically for established recipe settings. This means the recipe can be changed quickly and easily. As the mechanical energy factor can also be determined by setting roller distance, the die (thickness) does not have to be changed as often. This also helps reduce downtime. The CU Dynamic Mill is equipped with a die cleaning mode so that the operator can clean the die easily whenever necessary. As the meal does not have the opportunity to cake onto the die, which results in a quick start-up of the pellet mill. As the rollers retract automatically after each product, there is less wear of the die and roller 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 and also savings on maintenance and equipment. If required, existing Van Aarsen mills can be upgraded to the new advanced CU Dynamic.
