To produce a high quality product, manufacturers require reliable and efficient size reduction equipment for the milling of powders. The Hanningfield Uni-Mill is a conical mill designed for high integrity milling processes, offering many benefits over alternative milling methods including higher throughput, tighter particle size distribution (PSD), easier cleaning / maintenance and less noise, heat and dust.
Our industry leading conical mill is being used by customers worldwide in industries including pharmaceutical, biotech, nutraceutical, chemical and food. Its high performance and versatile design means that it is suitable for a wide range of dry and wet milling applications.
Narrow PSD
The Uni-Mill removes irregularities from the material during the milling process and allows manufacturers to exactly control and achieve a narrow PSD. Controlling final PSD targets is crucial in maximising the amount of milled material within the required PSD range and to not waste valuable ingredients.
Conical mills are typically suitable for size reduction down to approximately 150 microns (80 mesh). The Uni-Mill is designed to generate very little heat during the milling process so as to keep material properties unchanged as much as possible.
Interchangeable Tooling
The Uni-Mill offers incredible versatility as it is possible to achieve a wide PSD spectrum with the same mill. This helps to achieve the flexibility manufacturers require in production, as different forces and particle sizes can be achieved by changing the impeller type and screen type respectively; hence the cone mill can be used across a broad range of applications simply by changing a couple of parts.
Mills are available with a wide range of screen and impeller tooling, allowing for the various required final particle sizes and throughputs.
Typical Applications
We supply a range of conical mill models for different applications (dry and wet), ranging from small scale laboratory to full scale production. All mills are fully scalable from laboratory to pilot to production, so the results achieved on a lab mill can be replicated on a production size model.
Below is some examples of applications the Uni-Mill is suited to:
> Milling into Drum: The conical mill can be hand-fed allowing immediate discharge into the drum below (various methods of dust containment are available)
> IBC to IBC Milling: 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
> Isolator Milling: The Uni-Mill is suitable for isolator integration using our ‘through-the-wall’ design – the milling head is mounted inside the isolator, while the motor and controls are external
> Table Top Laboratory Scale Milling: The Uni-Mill M05-U is suitable for table-top use, such as those performed in R&D or lab scale applications – product can be milled into bags, drums etc. (containment available)
> Wet Milling (Post-Granulation): Milling after granulation increases the surface area of the material, enabling a faster, more consistent drying process downstream
> In-Line Vacuum Transfer Milling: The Uni-Mill can be integrated with vacuum transfer systems for the automated loading or unloading of process machinery, with in-line conical milling (example application: unloading a fluid bed dryer)
Our extensive experience in the process industry, coupled with our range of high quality products, means that we are able to supply the mill as an item of standalone equipment, or as part of a fully integrated system. We can design, manufacture and install full turnkey systems to customers.
