The production of ethanol is a demanding process. Ethanol producers are therefore dependent on the safe and reliable operation of the crushing process at the beginning of the entire production process. The production of ethanol is traditionally carried out through the fermentation of sugar or starch. Fruits or crops are used for this purpose. Ethanol extracted from straw is also becoming an increasingly interesting option worldwide. Excellent grain structures with high throughput rates and availability are a precondition for highly competitive ethanol and alcohol production. We optimally prepare the input materials for your ethanol and alcohol production and deliver reliable capacity and quality commitments for our crushing. Take advantage of our experience in natural and artificial fermentation lines.

60 years of expertise
Grinding solutions for the production of ethanol and alcohol

We have been building hammer mills since 1959 and supply our customers with tailor-made systems: From simple self-feeding grinding systems for small operations to computer-controlled large chamber mills with automatic screen change. Our high-speed mills are well established in the production of bio-ethanol, drinking alcohol and in the brewing industry. These are robust universal machines for small to medium throughput volumes. They are suitable for coarse and fine grinding.

The VDK high-speed mill is one of the most successful machines for the production of ethanol and alcohol. It is a robust hammer mill for medium throughputs. The screen is made of two parts and can be changed without using any tools when the machine is at a standstill.  The VDK high-speed mill is capable of processing all cereals, oil fruits, starch plants and their by-products, individually or in the form of recipes.

Our feeders

The distributed loading of the product across the entire width of the hammer mill has a significant effect on the grinding process. It makes a substantial contribution to efficiency and low-wear operation. The feeders are used to supply the aspiration air for grinding and they guarantee a safe product. We can provide you with the right feed technology, customised to the properties of your product and the structural configuration of your system.

The AGS air-gravity separator is well suited for the continuous separation of foreign bodies from bulk materials. Dosing occurs in combination with a dosing screw, which can also convey non-free-flowing bulk materials such as flours and bridge conveyor lines. The side doors and retractable magnets as well as foreign object catching lugs ensure easy cleaning.

The DA drum feeder is suited for the continuous separation of foreign bodies from bulk materials. This variant stands out due to its compact design and the loading of the mill directly from the above-lying upstream container. The dosing can be load-dependent in combination with a frequency converter.

The R vibration feeder is used to feed and dose free-flowing bulk material. Vibration feeding is also suitable for materials that are difficult to flow and bulky products. Dosing is load-dependent in combination with a thyristor control. A magnet ensures the separation of magnetic substances.
