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
The biomass shredder BMS in operation
The biomass, such as solid manure, straw or silage, is fed into the machine from above, pre-shredded by a ripping comb above the rotor and then enters the impact zone. Shredding then takes place by means of a rapidly rotating rotor and impact bars made of wear-resistant material. The beaters mounted on the rotor provide a blunt de-fibering action, resulting in a homogeneous and well-digested substrate that is ideally prepared for anaerobic digestion.

High machine availability and a long service life increase the economic efficiency of the Biomass Shredder BMS:
- Smooth running of the machine due to ripping combs for distribution of the material
- Impact parts and beaters made of wear-resistant materials such as Hardox and carbide
- Monitoring of unbalance, contaminant ingress and vibrations with the aid of a vibration sensor
- Energy savings due to fewer floating layers and lower agitation power in the fermenter
- Insensitive to impurities, as no sharp tools are used.
- Clog-free operation due to discharge in the bottom of the impact chamber
- Bearing temperature control
- Less build up due to stainless steel plates
Maintenance-friendly shredder for biogas plants
During the development of the Biomass Shredder BMS, special emphasis was placed on ease of maintenance. Both time, cost and ergonomics of maintenance were taken into account:
- Minimal wear costs due to replaceable shredding tools on the beater.
- Easy to change wear plates due to external screw connection
- Large maintenance door ensures maximum accessibility
- Adaptable to on-site conditions: Maintenance opening can be varied in 90° steps
- Maintenance platform at the maintenance door
- Easy removal of heavy parts by crossbeam with chain hoist (option)
