Havens Diervoeders pleasantly surprised following upgrade to the latest CU Dynamic pellet mill


Left: Havens Diervoeders, the Netherlands


Havens Diervoeders produces feed for pigs, cattle, goats, horses, rabbits and poultry. In practice the company works with more than 600 different recipes each with its own specific quality requirements. During the past two years Havens has tested the new CU Dynamic pellet mill by Van Aarsen in practice. Havens is positively surprised by the results of the new motor-operated roller adjustment and active slip control. Havens decided to upgrade the existing C900 mill to the new CU Dynamic pellet mill. To do this the complete internal mechanism of the pellet mill had to be replaced. Havens Diervoeders produces a wide range of animal feeds and


operates its pellet mill 24 hours a day. To obtain optimum feed quality and capacity Havens has to change its roller setting after each recipe. What is more, as production conditions vary every day (raw materials quality, capacity required per batch, air humidity and ambient temperature) the roller settings would even have to be adjusted during each production process. This would be impractical and time- consuming in the day-to-day operation of Havens Diervoeders and the desired production capacity would never be achieved. This meant

that in the past recipes sometimes had to be modified because they were too difficult for the mill. Motor-operated roller adjustment is the ideal solution for Havens Diervoeders. With one press of the button Havens can now determine the correct roller setting, even when the production process is in operation. This means that the manufacturer is now guaranteed optimum pellet quality for all feed types. Factory manager Hans Graat: “We are positively surprised by the reduced wear of the costly dies and rollers.” Operator Roel Brouwers adds: “There’s a lot less wear. This is due to the automatic retraction of the rollers after each batch. It’s also much easier to respond to the conditions on the day during the production process.” According to Roel: “The product passes through the die better. We can determine the hardness of the pellet better and set everything accordingly.” The motor-operated slip control detects slip and resolves the problem immediately. Factory manager Hans Graat: “The system reacts immediately. Without this system you’re always too late. It’s ideal as in the worst case we lose hours changing the dies. The whole package results in a series of cost savings and extra profits”.
