Mixer for forming ceramic suspension with reduced cooling and related method

A method of mixing a ceramic suspension with reduced cooling the ceramic suspension, the method comprising:

• adding at least two constituents of the ceramic suspension into a mixing bowl positioned in a mixing chamber, the mixing chamber and the mixing bowl being tilted relative to horizontal;
• sealing the mixing chamber with a lid and applying a vacuum through a first portal and using a vacuum source, creating a sealed mixing chamber, wherein the vacuum source is one of a pump or compressor;
• mixing the at least two constituents in the mixing bowl in the sealed mixing chamber with reduced cooling by simultaneously:
• first rotating a rotating mixing head relative to the mixing bowl,
• second rotating the mixing bowl, and
• moving the sealed mixing chamber in at least one linear direction;
• and
• adding a third constituent to the ceramic suspension through a second portal in the lid.
