AMANDUS KAHL increases energy efficiency with the new Distamat technology

For AMANDUS KAHL, this year's LIGNA is all about energy efficiency. At the world's leading trade fair for the woodworking and wood processing industry in Hanover from May 15 to 19, the company will showcase its wood processing equipment. Thanks to the specially developed electronic automatic pellet mill control system EAPR, the machines of the Reinbek-based company ensure optimum operation combined with low manpower requirements and long service lives. An intelligent automatic gap control called Distamat enables a predefined roller gap to be precisely maintained for optimum production results. 

Since the middle of the 1920s, AMANDUS KAHL has been developing pellet mills for a wide range of applications. Their reliable mechanical system as well as the individual configuration according to the customer's needs guarantee high throughput rates of up to 12 tonnes per hour. That is why they are particularly suitable for wood processing. At LIGNA, the machine manufacturer will be exhibiting its pellet mill 60-1500 and will be focusing on energy saving and energy efficiency.

For upstream and downstream processes, AMANDUS KAHL offers various systems for the preparation of wood products. For grinding wood chips, sawdust and wood shavings, the hammer mill and above all the pan grinder mill are used. Due to its crushing and grinding effect, the pan grinder mill is ideally suited for grinding relatively moist biomass. Its throughputs range from a few hundred kilograms to over 40 tonnes per hour. Special belt driers and coolers are used for drying and cooling, which optimally cool and dehumidify the final product before it is conveyed to a fully automatic packaging unit.

Technological edge through EAPR and Distamat
With the EAPR automatic pellet mill control, AMANDUS KAHL tackles the big topic of Industry 4.0. The EAPR enables optimum automatic operation of all flat die pellet mills of the company KAHL. It consists of a local control cabinet with touch panel (TP) and an intuitive software user interface. For more energy efficiency, AMANDUS KAHL thus takes into account the entire plant and equips all pellet mills with corresponding switching and control systems. If desired, the customised software enables the user to control and monitor the pellet mill, the dosing screw, the mixer, the auxiliary units - the cooler if required - and the respective upstream and downstream elements at any time. Once the process parameters have been specified, the EAPR controls the fully automatic operation, including error and alarm messages as well as system diagnostics. In the event of trouble, the system can be accessed via remote maintenance.

As a further option for automatic pellet mill control, AMANDUS KAHL has developed the Distamat, an automatic gap control system for a continuously adjustable and constant roller gap during operation. The constant gap between the pan grinder roller and the die is essential for pellet quality and stable operation. The system not only increases the pellet quality, but also offers a high degree of automation, which results in less maintenance work during operation, such as adjusting and checking the roller gap. 

Further information about the functions and possibilities of the KAHL machines can be obtained directly at booth F57 in hall 26.
