The classic for medium throughputs

ROBUST MACHINE FOR USE IN ULTRA-FINE GRINDING

The Hammer Mill VDK is designed for fine grinding in pet food and aqua feed production, as well as for coarse grinding, in the feed-milling, ethanol and wood industries. Specifically designed for efficient grinding for challenging recipes and products: The special 6-axis rotor design plus optimized beater configuration in combination with high beater tip speed guarantees maximum material contact for the efficient production of the finest feed as well as coarser products.

Specialist for fibrous material

FOR EXTREMELY EFFICIENT Size reduction OF FIBRES

The straw mill SD has been specially designed for crushing fibrous material such as

straw, hay, alfalfa, miscanthus, hemp, jute, coconut fiber

A comb in the inlet area as well as the special geometry of the grinding chamber grind the fibres particularly efficiently. Foreign bodies are separated by means of a catch pocket that is accessible from the outside. The beaters are fixed to carrier frames, which can be quickly and easily changed with a supplied device. This means that it only takes a few minutes to change the beaters and downtime is reduced to a minimum.

Increase your biogas yield

Grinder / Shredder for biogas plants

By de-fibering, crushing and grinding with Tietjen’s BMS, a higher gas yield is achieved, and difficult substrates can be made usable in the digester.

These raw materials are typically grinded and crushed in the Biomass Shredder BMS:

• Solid manure from chickens, cattle, horses, turkeys or pigs.

• Corn and grass silage

• Grass clippings and straw

• Sugar beets

• Crops and agricultural waste

• other biomass

Robust and durable

Depackaging machine for food waste

With a high throughput our equipment is designed for professional food waste recycling. Here, our system achieves the highest degrees of purity.

Today, DRM is in continuous use in various food waste recycling plants: it unpacks and sorts the food waste and thus optimally prepares it for recycling in biogas plants.

Separation of foreign matter – Tietjen press screw

Additional Dewatering of Foreign Matter from Organic Waste

Separated foreign materials such as plastic packaging from organic waste are usually still contaminated with sticky liquids. For cost-efficient thermal disposal, the foreign matter should be as free of liquids as possible after depacking and separation.
The screw press was especially developed for the removal of residual liquids on packaging material after the depacking and separating process of packed organic waste.  It is made entirely of stainless-steel (depending on the order), is extremely robust and easy to maintain. Therefore, it is ideally suited for demanding applications with difficult conditions, such as in industrial organic waste processing. The innovative design ensures a high pressing pressure with the best dewatering performance. The pneumatic control of the press flap ensures automatic adjustment to different materials. The separated liquid is collected and can be added to the remaining bio mass for energy recovery. A regular cleaning can be carried out via flushing nozzles.
