RUMBO Stone on Stone Grinder

Please Call

The RUMBO stone-on-stone grinder for the craft chocolate maker; a nice, heavy-duty melangeur with more features and functionality over competitor brands.


The Rumbo is 500 kg machine -- a heavy duty stone mill grinder designed for craft chocolate makers committed to traditional stone-on-stone grinding with improved functionality for more precise control over the parameters of the chocolate-making process.

Unlike other stone grinder systems where the base or the working bowl rotates, the Rumbo's wheels or millstones turn, driven by direct drive motor, so the pressure is harder and production time is less. Customers enjoy speed and temperature control, plus the ability to incorporate ambient or hot air into the tank to warm the stones prior to starting to release the cocoa butter from the nibs more effectively than from a cold start, and to continue as desired to obtain shorter processing times.


  • 2 solid granite millstones weighing 45 kg ea.
  • Millstones turn instead of bowl
  • Direct drive, adjustable speed motor - No belts, gears, or chains
  • Stainless steel working bowl capacity: 120 kg
  • Recommended Batch capacity: 60 kg
  • Plexiglass bowl cover with latch.
  • Forced ventilation with adjustable temperature; ambient up to 75°C (167°F)

Whether you are working from-the-bean, purchasing roasted nibs or working from chocolate liquor, the Rumbo stone mill grinder can be operated "low and slow" or "hot and fast" to create craft chocolate to suit the chocolate maker's intentions.
