Gruber GS2350 Dual Vessel Blender
Up to 700 lb capacity!

Heavy-duty, dual-mixing pot blender with two 350 lb (158 kg) capacity stainless steel pots for up to 700 lb total capacity, or for added flexibility to simultaneously blend two different formulations. Designed for batch cultured marble or onyx production.


  • Two large capacity (375 lb or 158 kg each depending on viscosity) stainless steel mixing vessels. Each vessel has its own 3 horsepower motor for thorough mixing

  • The heavy-duty stainless steel mixing blade is mounted to a pneumatic boom that is used to raise or lower the blade into either vessels.

  • The blade attached to the boom assembly by a twist lock mechanism for quick blade removal and replacement. When in the raised position, the blade can be rotated away from the mixing vessel for unobstructed access or positioned to blend the next vessel of matrix.

  • Can be used in conjunction with a Batchmaster with the optional rotating base.
