Grinding

Pre and post grinding
Icon Grinding

Post grinding is the grinding of a mixture of different raw materials in a batch process.
Pre grinding means that every raw material is ground separately and continuously.

The decisions for either post grinding or pre grinding are dependent on the specific customer requirements and possibilities.

  • Post grinding
  • Many recipes
  • Hammer mill requires a higher capacity than the feed mill capacity
  • Requires more storage bins
  • Pre grinding
  • A few recipes/ raw materials
  • grinding capacity of the hammer mill is equal or even less, compared to the feed mill capacity
  • Requires more storage bins

The GD and 2D hammer mills are designed for the animal feed industry, to grind raw materials into small particles and meal. Both the GD and 2D hammer mill series cover capacities ranging from 5 – 100 tons per hour, dependent on type of raw material, formula and required grinding structure and can be incorporated in a pre-grinding as well as a post grinding system as a complete grinding solution including pre-bin, feeder, magnet cleaner, hammer mill, discharge hopper, aspiration filter, fan and control system.
