KAHL belt units dry and cool pellets without the formation of cracks.
By means of modular design, the size and the process technology of the plant can be exactly adapted to the particular requirements. Subsequent extension of the plant is also possible.
Due to their flat design, the KAHL crumblers can be integrated into existing plants without any problem. The modular design ensures easy roll replacement towards the front or to the side. Our customers benefit from the advantages of a fully developed technology and solid machine construction.
KAHL crumblers can process pellets and coarse-grained products. Crumbles have favourable properties in feeding.
Using the KAHL crushing roller mill cereals, legumes, oilseeds, and feed mixtures can be crushed efficiently and with a considerably lower expenditure of energy compared to the hammer mill. Our chilled cast iron rollers are available in three sizes. The advantages of the KAHL plant:
Compound feed for pigs, poultry or cattle produced in the KAHL crushing roller mill offers advantages in animal nutrition:
The main part of the system is a rotation nozzle which allows an ultra-fine spraying of the liquids. The special distribution of the solid matter flow ensures spraying of the product from all sides.
Sophisticated machines such as the annular gap expander and the pelleting press require an appropriate control system. For this reason, the ESEP (Electrical control System of the ExPander) and the EAPR (Electrical Automatic system for PResses) have been developed by the company KAHL.
The individually programmed control of a complete plant or the automation of complete production lines also belongs to our range of services, including switch cabinet manufacture.
A high quality awareness establishes KAHL on the wood pellet market. For more than 30 years Kahl has dealt with this product and can offer a sophisticated process for the production of high-quality pellets with very good combustibility, now.
Robust design and a high availability of the plant ensure economic operation. KAHL pelleting presses are available with a drive power of 3 kW to 500 kW and a throughput of 300 kg/h to 8 t/h.

Pelleting of renewable raw materials for energy recovery has been a topic for KAHL for more than 30 years, after receiving corresponding research assignments following the energy crisis in the 1970's. Straw and dried forage pelleting plants have formed part of our delivery programme since then, too. So, we can rely on long-standing experience.
The worldwide energy and resource consciousness has increasingly moved materials into focus which have been unexploited so far, such as straw, rape straw, or by-products from cereals and pulses. Pellets offer enormous advantages, e.g. for thermal utilisation:
For decades, KAHL pelleting plants have been applied successfully for compacting organic products of different consistency.
Do you need constantly uniform, optimally compacted pellets? Our presses are able to produce pellets of 2 to 40 mm in diameter. The KAHL pelleting presses process also materials which are difficult to compact:
The product is formed into endless strands at a high throughput which are precisely cut by means of knives. With a roller speed of only 2.5 m/s an optimum deaeration of the product is achieved. The plants are extremely silent with a noise level of less than 70 dbA. 12 types of pelleting presses are available for different applications.
For gentle drying of wood shavings and wood chips we have developed special belt driers ensuring:
The plants which are individually composed of modules ensure convectional drying using hot air. Thanks to an intelligent control system, the KAHL fabric belt drier adapts to varying moisture degrees and climatic conditions. Depending on the demands, ambient air or recirculated air with a temperature of up to 200 °C are used in KAHL belt units. Inert gas designs avoid emissions and dust explosions.
Our fabric belt made of special plastic serves not only for transport but also as an exhaust air fan. The drying plants are also suited for high throughputs at automatic operation.
Wood shavings, sawdust, wood chips, and other lumpy biomass raw materials are crushed in an eco-friendly way using the KAHL pan grinder mill:
The mill can be designed for capacity ranges from a few hundred kg up to 20 t/h and does not need much space. Both dry and wet raw material is processed.
KAHL pan grinder mills defibre wet wood chips of the categories G30 and G50. Subsequent fine grinding with conventional hammer mills is not necessary.
With KAHL flat die pelleting presses the product is ground to a particle size of 0.4 to 0.6 mm. Our company has decades of experience in the compaction and pelleting of raw materials. This process ensures effective and economical granulation of difficult products such as waste tyres - completely without nitrogen.
The flat die pelleting presses are characterized by their sturdy construction and their high flexibility. Granulation presses for waste tyres achieve a throughput of 2.5 t/h in three-shift operation.
Waste belongs to the category of the most difficult materials to be processed. With KAHL plants municipal and industrial waste can be transformed into valuable alternative fuels.
Seven million tons of municipal waste can be processed into about three million tons of alternative fuels with a caloric value of abt. 17,500 KJ/kg. They are used as an important energy source in the following sectors:
Compacted and dust-free municipal and industrial sewage sludge can be treated further at low costs. KAHL sewage sludge pelleting provides:
After an appropriate pre-treatment, the solid content of the sewage sludge is between 60 and 95 %. By means of the pan grinder rollers it is ground and compacted on the die. The bulk density of the pellets is about 800 kg/m³.
