The Shredding Solution for the Smooth Operation of Your Biogas Plant
Tietjen’s biomass shredder BMS is a vertical grinder that efficiently and homogeneously processes biomass for anaerobic digestion. 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
Functional principle
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.
Advantages at a glance
PROBLEM SOLVER FOR BIOGAS PLANTS
- Efficient particle size reduction of even the most difficult substrates
- Flexibility and economy using alternative raw materials
- High throughput rates of up to 15 t/h (depends on substrate)
- Process optimisation through better pumping and agitating properties, minimisation of the floating layer
RELIABLE OPERATION AND LONG DURABILITY
- Robust welded construction for continuous industrial operation (24/7)
- Impact parts and beaters made of wear-resistant materials such as Hardox and tungsten carbide
- Clog-free operation due to discharge in the bottom of the impact chamber
- Resistant to impurities, as no sharp tools are used
HIGH AVAILABILITY AND EASY MAINTENANCE
- Large maintenance door with platform ensures maximum accessibility
- Position of the maintenance door can be adjusted in 90° steps to suit the conditions on site
- Minimal wear costs due to replaceable shredding tools on the beater
- Easy to change wear plates due to outside screw connection
- Easy removal of heavy parts by crane traverse with chain hoist (option)
HIGH SAFETY OF PERSONNEL AND PLANT
- Door securing with key transfer system
- Monitoring of unbalance, contaminant ingress and vibrations by means of vibration sensor
- Sensors for monitoring the bearing temperature
