This pair of dry grinding attritors, the 30SD and 50SD, 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 attritors include a one-piece stainless steel tank cover with Meco shaft, and a variable frequency drive that is housed in a NEMA 4X/12 washdown-duty enclosure. An LCD operator interface module displays agitator RPM, motor AMPS, and motor HP being used. The 50SD is powered by a 75-HP, TEFC inverter-duty motor, while the 30SD has a 40-HP motor.
