Once you have decided on a conical mill for your process, you then have a choice between under-driven and over-driven mills. Both options will have advantages in different applications, so it is important to know the process and material specifics in question before deciding.
Here’s a brief guide that highlights the key differences between the under-driven and over-driven conical mills.
Under-Driven Conical Mill Benefits
> Spacer-less design with preset optimised gap for milling. Spacers are time consuming to set up and heighten the risk of operator error in setting the gap correctly. The spacer-less design eliminates these issues.
> In-line feed and discharge for higher capacity milling. As the inlet is in-line with the outlet on the milling chamber, this makes it better for in-line processing (e.g. container to container milling) and easier system integration due to the minimal stack-up height.
> Hygienic, easy clean design. Detachable mill head allows the chamber to be removed from the machine for easier cleaning.
Over-Driven Conical Mill Benefits
> Perfect for heat sensitive materials. An over-driven conical mill uses a belt-driven gearbox which runs cooler than the gear driven alternative. This means that the machine is able to run cooler and is, therefore, better suited for heat sensitive materials.
> Robust design for more rugged applications. The belt-driven design is generally more robust and is suited to tougher materials and plant-like materials.
> Ability to change the gap between the screen and impeller. The over-driven conical mill uses spacers to set the gap which allows the gap to be altered depending on the material being processed.
> Low noise for a better working environment. Another advantage of this design is the lower noise created due to the belt-driven operation compared to mechanical gears.
The choice between an under-driven and over-driven conical mill will be determined by your application specifics. We have an experienced team that will guide you through the options available, so you choose the mill that delivers the best results for you.
