Question about Kenwood Spice mixer AT320A

Yes, the AT320A spice grinder is compatible with the Titanium Chef Baker. It can be connected to the high-speed connection of the food processor.

I don't know the Titanium Chef Baker, but in my experience the connections are always the same on Kenwood machines. However, I have already used various accessories (including the spice mixer) with various "guest machines" :-).
