Product Overview Conical mills are designed for milling processes in the pharmaceutical, food, chemical and related industries. The conical mill offers numerous benefits over alternative milling methods including higher throughput, tighter particle size distribution, easier cleaning/maintenance and less noise, heat and dust. They are suitable for a wide range of applications and offer full process scalability from laboratory to pilot to production. The Uni-Mill U-series (M05-U, M10-U, M20-U, M30-U) utilises the current industry standard under-driven conical mill design, featuring a...

The Uni-Mill M05-U is designed for laboratory and small scale applications. The unit features an 83mm diameter screen (3.25”), enabling throughputs up to ~200kgs/hr (425 lbs/hr). The Uni-Mill M20-U is designed for a wide scope of production applications. The unit features a 203mm diameter screen (8”), enabling throughputs up to ~2000kgs/hr (4250 lbs/hr). The M05-U features an 8” feed chute with 6” outlet (note: inlet / outlet configuration can be modified to suit any application requirement). The unit is supplied with a 0.375kW motor set to a standard speed of 3600RPM (includes variable...

Typical Applications Milling into Drum Isolator Milling The conical mill can be hand-fed allowing immediate discharge into the drum below (various methods of dust containment are available). By positioning a bin above the mill, and another bin below the mill, product is released from the top IBC, milled, and then passes directly into the bottom IBC. The Uni-Mill is suitable for isolator integration using our ‘through-the-wall’ design. This mounts the milling head inside the isolator, whilst keeping motor and controls external.

Tooling Screens A wide range of screens are available for satisfying the required particle size across nearly all milling applications. Screens are available with a wide range of hole sizes, and the following hole shapes: Round, Square, Slotted, Grater and Conidur hole. Impellers A wide range of impellers are also available, for providing the right milling action (e.g. maximising throughput or minimising fines). Impellers are available with the following arm profiles: round-bar, square-bar, bevel-bar, reverse bevel bar. We can also engineer custom impeller shapes upon request Spare and Care...
