From Machines - Pelleting
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 products are pressed through our flat die by pan grinder rollers, formed into endless strands, and then cut to the desired particle length by means of knives. The diameter of our pan grinder rollers is between 130 and 450 mm. The diameter of the die is 175 to 1500 mm, resulting in pellets of 2 to 40 mm in diameter. The drive motor has a power of 3 to 630 kW.
The product to be pelleted is fed by gravity. The low roller speed of approximately 2.5 m/s ensures a good deaeration of the product. As a result of the low speed, the press noise is below 70 dbA. The thick product layer between the pan grinder rollers and the large die surface results in a high throughput, even in case of products which are difficult to pellet. Mixtures with high levels of fat and molasses can be effectively pelleted. Each pelleting press is tested before supply under full-load simulation.
- The roller gap can be adjusted during operation
- Permanently lubricated roller bearings prevent contamination by lubricating grease as well as grease losses
- Quickly exchangeable pelleting tools
