The Milling Stone

The milling stone forms the heart of the grain mill.

Today you can choose between the synthetically produced milling stone made from corundum-ceramic or the naturally grown granite milling stone.

Based on experience and full of conviction, we decided in 2016 to produce exclusively mills with the granite milling stone mined in nature under the name of Salzburg flour mills.

GRANITE MILLING STONE

Decisive for this decision were the convincing characteristics:

  • Extreme longevity
  • The almost absolute resistance to breakage
  • The only natural abrasion – without artificial additives
  • The self-sharpening
  • The delicacy and baking joy of the flour
  • No noticeable stonegrit in the flour

The size of the milling stone is not decisive for the refinement of the flour.

The best possible adjustment of the milling stone 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 milling stones 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 IS NOT GRANITE

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

40 years ago we began looking for “the ntural millstone”. 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 milling  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 40 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 milling stones have been reported.

Pair by pair our granite natural millstone are individually and carefully worked by hand and adjusted to each other, which very time consuming.

Each pair of millstone is unique!

The granite milling stones 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 milling stones which are then as good as new!

A Granite milling stone is 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 Stones

Almost all the mills offered in the trade are equipped with an artificial millstone

These consist for the most part of aluminum oxide and silicon oxide. These consist for the most part of aluminum oxide and silicon oxide.

Under high pressure the corundum and ceramic mass is pressed into the millstone form and subsequently burned in a furnace at a very high temperature.

The milling stones are hard, self-sharpening and durable.

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