Automation is in the focus of KAHL systems. We have developed the EAPR and DISTAMAT for the automatic control of our KAHL flat die pelleting presses. The EAPR from KAHL consists of a local control cabinet with graphic touch panel (TP) and a PLC with Step 7 CPU as central components. It thus controls and regulates all relevant process parameters. As an option, the DISTAMAT can be used for continuous adjustment and regulation of the roller gap, as good pellet quality requires a constant roller gap. Our EAPR and DISTAMAT systems therefore ensure optimum press operation combined with low manpower requirements.

A special field of application for KAHL presses are oil mills processing various oil seeds into food. The pressed oilseeds can be directly transformed into pellets with the KAHL flat die pelleting press.

Depending on the setpoint deviations, the pressure of the hydraulic system of the pelleting press is controlled in such a way that the roller gap is kept constant. In this way, our DISTAMAT allows a continuous preselection of the roller gap. Apart from that, the direct contact of die and pan grinder rollers which usually results from a product shortage is avoided. Thus service lives of pan grinder rollers and die are considerably increased. By means of alternating lifting and lowering of the pan grinder rollers, the optional unblocking programme causes an automatic unblocking in case of an overfilling of the pelleting press.

The main part of the system is arotation atomiser permitting the finestspraying of liquids. The specialdistribution of the solid matter flowguarantees an all-round liquidcoverage on to the product.

Our KAHL pelleting presses facilitate storage and transport of your bulk products and product mixtures. Particularly fine-particle or dusty products are often a challenge when it comes to storage. Both the porosity and the volume require special measures – also during transport. Our KAHL pelleting presses help you to save operating, transport and above all storage costs. Products with different structures, bulk densities, binding strength and particle sizes are no problem for the flat die pelleting press. It is also irrelevant whether the products are powdery, fibrous, lumpy or pasty. The following products are mainly pelleted: Compound feed, raw materials and mineral mixes as well as by-products in flour and oil mills or malthouses. Also straw, wood, biomass and dried sludge (see sewage sludge).

The annular gap expander consists of a thick-walled mixing tube with replaceable liners and cantilevered shaft which is provided with proportioning, mixing and kneading elements.

Two steps with one machine: The crown expander not only expands a product, but shapes it at the same time. This allows shaped products to be produced for all animal species.

Our mixing conditioner enables you to condition feed mixtures or individual products with the addition of steam, water and liquids. Conditioning is necessary to achieve the best feed quality. At the same time it is required for the effective performance of the downstream pelleting presses. The mixing conditioner is therefore ideally suited for effective and economic thermal treatment of compound feed. During conditioning, steam, water and other liquids are added to the input product with firmly defined ratio of retention time and throughput. A good filling degree results in a uniform and sufficient absorption of steam and added liquids. Optimum product treatment requires precise monitoring of the conditioning parameters, such as temperature and moisture.

Wood chips, sawdust or wood shavings as well as other lumpy biomass can easily be ground with our KAHL pan grinder mill.

Our KAHL hammer mills are used for the grinding of feed components and mixtures, but also for all types of grain, straw, wood and similar products.
