VIV Asia 2013, Roller mill and expander Amandus, CropTech-FeedTech debate, co-organized by Perendale

  1. 1. Intelligent Solutions in the Feed Processing ChainCoarse particle structure – grinding by roller mill and processing with expander Olaf Naehrig, Senior Area Manager Amandus Kahl GmbH & Co. KG Crushing Roller Mill Kahl Expander
  2. 2. Intelligent Solutions in the Feed Processing Chain Effect coarse particles for production costs and animal nutrition and health:A. Energy consumption: B. Animal nutrition and health:Hammer mill 7 kWh/t Coarse particles are superior in digestionRoller mill 2 kWh/t and for animal healthEnergy saving, up to 5 kWh/t Key words: proventriculitis, ascites, gizzard erosion, ulcers, salmonella too fine suitable particle size
  3. 3. Intelligent Solutions in the Feed Processing ChainEffect of Coarse and Fine Grinding Stage grinding with roller mill + hammer mill 100 90 80 70 hammer millTotal proportion in % 60 50 40 30 roller mill 20 10 0 0 0,5 1 1,4 2 2,8 Particle size in mm Wheat roller mill gap 0,5 mm Corn roller mill gap 0,75 mm Wheat hammer mill screen 4 mm
  4. 4. Intelligent Solutions in the Feed Processing ChainMaintaining coarse particles in downstream processing Coarse structure maintained in expander Pelleting presses grind down coarse particles!!
  5. 5. Intelligent Solutions in the Feed Processing Chain Gap Adjustment Device: • PLC control • Gap adjustment by manual spindle drive • Continuously adjustable • Gap size: 0,3 – 13,0 mm (+/-0,1mm) Treatment control: • PLC control • Annular gap adjustment by hydraulic cylinder • cone positioning • flexible energy inputs • adapted conditioning
  6. 6. Intelligent Solutions in the Feed Processing ChainOutlook / Trends:• Online Particle Measurement during grinding process • Technology already implemented for precision grinding, e.g. in coffee and pharmaceutical industry• Phase-Feeding vs. Universal Feeding • Production of smaller dedicated batches instead of large batches • Fast and easy change of processing parameters required • Advantage of Crushing Roller Mill with gap adjustment• Processing of mono-components • Production of specialty feeds in small batches• Efficient utilisation of feed • Coarse grinding allows more efficient nutrient uptake• Increased use of expander for better feed conversion rate, lower feed costs and better animal health
