To micronize ceramics, dispersion is performed with a bead mill.

• The beads were offset in the disperser due to the pump pulsation, leading to excessive dispersion.
• Beads were discharged from the bead mill outlet and were bitten by the pump, which sometimes led to emergency stops.
• Because high-mix low-volume production is performed, the liquid must be changed frequently, leading to a high frequency of cleaning.

In cooperation with a bead mill manufacturer, we developed a Smoothflow Pump dedicated for use with bead mills.

• Because there is no pulsation, the bead offset could be suppressed, which made it possible to obtain sharp particle size distribution.
• A special valve seat whose clearance was adjusted to match the bead diameter was used, so emergency stops no longer occur even if beads flow into the pump.
• Sanitary specifications were used for the liquid end part of the pump, thereby making this pump easy to clean even during inline cleaning.
• Ferrule joints, which enable disassembly without requiring any tools, have been used, making it possible to disassemble and clean the pump in a short length of time.
