Aluminum is widely being used in a grinder and in general, an aluminum grinder will outlast a plastic grinder, right? well, that really depends on really how you look at it. Does a grinder that contaminates your medicine consider as being durable?
Basically aluminum is a very soft material, yes, it sounds weird but it is the truth and still, it is not the only reason aluminum grinders fails. For the grind to go on, rotation is applied, having 2 surfaces of the same molecular structure rubbing against each other is not a good idea.
So, how come our ALUMINUM GRINDER IS SAFER?
The answer lays in our core technology, our FRICTION REDUCTION RING is what makes our grinder to stand above the rest. Not only it will degrade prior to the ALUMINUM but also we have applied an extra safety measurement by HARD ANODISING, pigment-free! (very important), the main parts, so the aluminum is not as soft as it was before and actually make it hard as steel.
So, the aluminum will not fail, but what about the plastic ring?
The Friction reduction rings degradation is locked outside of the grinding chamber. As the ring is softer than aluminum, it will get chunks displacement rather than microscopic dust, so you can easily address maintained and prevent medicinal contamination.
