Oak pellets

Hardwood makes dense, heavy pellets but puts more load on the die than pine.

We grind oak finer and pelletise it on a die of a different thickness than for softwood. Oak pellets have a high calorific value and are sought after by owners of fireplaces and A1 pellet boilers.

1. Feed hopper needed

   Takes in the raw material and feeds it evenly into the line.

   Feed hoppers with a screw discharger (V-shaped walls), Feed hoppers with a slat scraper (vertical walls)

2. Grinding needed

   The material has to be ground to sawdust size before it reaches the pellet mill.

   Hammer mills

3. Drying it depends

   A dryer only above 15% moisture. We measure it on a sample.

4. Pelleting needed

   The heart of the line. For this material: thicker die, 6 mm holes.

   Granulators

5. Cooling it depends

   Needed from about 200 to 250 kg/h. It can be skipped with big bags, not with small bags.

   Coolers

6. Screening needed

   A drum or vibrating screen separates dust from the finished pellets.

   Drum screens, Vibrating screens

7. Packing your choice

   15 kg bags, big bags or bulk, depending on the buyer.

   Packaging systems

8. Transport between stages needed

   Belt and screw conveyors connect the machines into one line.

   Belt conveyors, Screw feeders, Redlers

9. Control cabinet needed

   Controls the whole line, also remotely from a phone.

   Industrial automation
