A pair of dry grinding attritors (30SD and 50SD Attritors) work in tandem with one unit milling a dry powder for nano-sized particle reduction and then transferring the material to the other unit for complete and thorough dispersion and blending in a second stage wet process. The dry powder material created in the 30SD is transferred via dry powder pump into the 50SD for this two-stage process. Both include a one-piece stainless steel tank cover with Meco shaft and a variable frequency drive that is housed in a NEMA 4X/12 wash down duty enclosure. An LCD operator interface module displays agitator RPM, motor AMPS and motor HP being used. The mills are also equipped with a specially designed process control timer package per the customer’s request, which includes a process run timer, temperature warning and cut-off switch, as well as cooling water flow sensors.
