The Milling Stone

The milling stone forms the heart of the grain mill.


You can choose between the synthetically produced millstone made from corundum-ceramic or the naturally grown granite millstone.

Only the smallest amount of abraded particles from both the synthetic and the natural milling stones are transported to the freshly milled flour.

The same applies to both milling stones:
The size of the milling stones is not decisive for the refinement of the flour.

The best possible adjustment of the millstone diameter to the speed of the motor is however essential. This combined with the new warmth and energy optimized geometry of the milling mechanism provides for a gentle milling of the grain.

The special flexible positioning of the millstones has two advantages.
A quieter milling process and protection damage to the milling mechanism due to foreign particles in the grain.

In the following you can find detailed information on the granite and corundum-ceramic milling mechanisms.
Granite Milling Mechanism:

There are hundreds of different kinds of granite but only a few of them have proved suitable for use as millstones.

35 years ago we began looking for “the stone”. For many years we have been searching all over Europe and have tested the pros and cons in order to find the granite most suited for use in our Salzburger MT-Series. Today we know which characteristics the stone must have with regard to hardness, wear, self sharpening and above all how it must behave during the milling process.
We Salzburger grain mill constructors can also claim with pride that we are unique in Europe in having 35 years of experience with granite millstones for use in household mills.

The naturally formed granite which is carefully selected by us is a completely natural product – free from additives – nature pure!

One characteristic of granite is its high resistance to abrasion being harder than many types of steel. Granite is perfectly bonded by nature (without any bonding agents), it is self-sharpening and has proven itself to be durable. Until today no forms of allergic reactions to granite mill-stones have been reported.

Pair by pair our granite stones are individually and carefully worked by hand and adjusted to each other, which very time consuming.
Each pair of stones is unique!

The granite millstones used in our mills have proven to have an extremely long service life. In fact even after many years of service we have been able to rework granite mill-stones which are then as good as new!

Granite millstones are of course pollution-free.

It goes without saying that the modern granite milling mechanism has been constructed according to the latest findings in millstone technology.

Corundum-Ceramic Milling-Mechanism:

The millstones are extremely hard, self-sharpening and durable.

In addition to the conventional corundum-ceramic milling mechanism (grey in colour) on some of our grain mill we offer – or at additional cost – the higher quality Superior Corundum-Ceramic Milling Mechanism. This is more resistant to abrasion and therefore is more durable
