Sonic's Benchtop Colloid Mill measures only 18 x 18 inches. It uses a 115 volt, 1 phase AC motor for convenient electrical hookup. This mill is used extensively for validation trials, re-formulation test work in the lab, and process development. These units are custom fabricated to meet your needs and can be built as a fully automated system with feed pump, PLC controls, instrumentation, etc. It scales up directly to any of our mills, including the new 2004 RotoMill designs.
