Wet grinding is performed in the ball mill as shown in Figure. 3. This operation is similar to wet mixing with the only difference that the ball-mill running time is 20 to 24 hours, instead of 8 hrs, to ensure the particle size reduction to 2 to 16 µm. After wet grinding, the slurry is driedup in the - oven.

A few possible kludges: 1) On a small horizontal mill, make up a fly cutter to fit the arbor. If the arbor is over, say, 1 3/4" diameter, make up a smaller arbor. This assumes the cross travel is enough to cut the cove in your part. 2) On a regular vertical mill with a tilting head, turn the head 90 degrees and insert an arbor with a fly cutter.
