Salzburg Grain Mills

This is how we build mills

The heart of the grain mill is the milling-stone.

From experience and full conviction, we decided in 2016 to produce exclusively mills with granite grinding stones obtained from nature under the name Salzburger Grain Mills. The decisive factors for this decision were the convincing properties:

  • Extreme durability: Our granite grinding stones often provide excellent service for 30 to 40 years with the factory sharpening and can be resharpened by us for their second, equally long life. Higher demands on the durability of a product cannot be made.
  • Almost unbreakable: That there has ever been a break of the grinding stone or chipping of parts is not known to us. Even the grinding of small pebbles that can be found in the grain, our granite grinding stones withstand and thus protect your teeth. Therefore, we gladly provide a lifetime warranty on our natural stones*
  • Granite is naturally perfect: Without any artificial binding agents and without additives, granite as a pure and natural material has ideal properties for grinding grain. Environmentally friendly and sustainable, granite is the only right choice for us.

The flour from natural stones can hardly be described in words… Airy, powdery, velvety, soft.
These words are not enough. You have to feel the flour between your fingertips.
Flour that you buy pre-packaged in the store is classified into types and produced in standardized processes.

Grind it yourself with an original Salzburger grain mill and experience the differences and special qualities of the flour already in the bowl that catches your flour under the spout. How it piles up into flour cones and slips down, how easily it can be shaken or later during kneading behaves, unfolds during baking, and ultimately reveals itself in the outstanding taste.

Words from experienced bakers count here more than the standards of the industry.

Only with the flour from my Salzburger can it be done – this was told to us at a show by an Upper Austrian farmer, who always bakes a very special cake for her small community for the harvest festival. And one could literally see the pride in her eyes.

From granite block to grinding stone:

Our granite stones are carefully and patiently matched to each other and worked on with manual skill, each pair individually.
The manufacturing of our grinding stones begins with a grinding stone blank, to which the basic shape of the grinding surfaces and perfect roundness are given.
Then follow several uncompromising optimization steps, in which perfection is worked out through grinding tests, repeated dismantling, and resharpening, to achieve the desired fineness of the flour and the grinding performance.
It is a matter of experience and something very individual, which shape the professional gives to the stone, until hard and bulky grains like rice or chickpeas are ground as finely as rye and wheat.
It is almost like building a musical instrument, where often several paths lead to an outstanding result.

Now you understand the effort required to transform the granite blocks quarried from the quarry into small, round, perfectly balanced grinding stones. And how simple it is, in comparison, to industrially produce artificial grinding stones made of corundum ceramic, pressed into shape with chemical binding material, in high-temperature ovens.

Each pair of stones is unique!

Our search for the right granite for our mills began over 40 years ago. Even at our beginnings, in the pioneer times in the 1970s, we set out in search of “the stone”. For years, we searched in Austria, Germany, and all over Europe, examining the advantages and disadvantages of different natural stones, to find the most suitable granite for the Salzburger MT series.

Even today, the blocks are quarried in the same area in Europe, but our knowledge about the value of these stones is much greater. More than ever, we appreciate properties such as hardness, self-sharpening, and durability, and especially the quality of the flour that can be produced with granite stones.

Moreover, we, Salzburger mill builders, can today proudly claim to be the only ones in Europe to have over 40 years of experience with granite grinding stones for electric household mills.

Our Stainless Steel Thread

and the symbiosis with the grinding stones of the grain mills MT 5 ED, MT 12, and MT 18

  • The stainless steel thread, together with the grinding stones, is the most important part of the mill
  • Guarantees the finest flour for decades
  • Ensures no change in flour fineness during grinding

Over 40 years ago, Ing. Johann Thurner set himself the ambitious goal to develop the best possible adjustment system for his mills.
Since then, a precise steel thread, matching the massive diameter of the mill housing, adjusts the distance between the two grinding stones.
A system that still ensures the finest flour, even after decades, in many mills worldwide.

Today, modern CNC machines manufacture the thread, with utmost precision, not from steel but from the highest quality stainless steel alloy available.
The weight of the thread of the mill MT 12 is about 3.5 kg with a diameter of 16.5 cm.
This massive component is what gives a Salzburger grain mill the stability and robustness to perfectly align the two grinding stones.

This guarantees the finest flour for decades and no change in flour fineness during grinding

The symbiosis of adjustment with the grinding stones
Every adjustment system adjusts the distance between the lower and upper grinding stone. The stones always grind in direct interaction with the adjustment to produce fine or coarser flour – as desired.

Therefore, not only the stones but equally the adjustment system is important for the fineness of your flour.

Whether you turn a dial or a funnel or operate a slider, you are always changing the distance between the stones.

If an adjustment system does not work precisely, then the grinding stones are not exactly flat (i.e., they do not lie exactly parallel to each other). Then the stones cannot grind the finest flour, and the coarse portion of the flour is significantly increased.

However, often one hears: My mill is only 10 years old (the problem can occur sooner or later) and no longer grinds fine! Most often in this case, the adjustment system is to blame, not the grinding stones, as is often suspected.

The stainless steel thread guarantees that the set fineness level does not change during grinding. 

For a layman, it may be difficult to assess the value of the stainless steel thread. But technicians, metalworkers, etc., know about the material costs, the manufacturing costs, the requirements for precision, etc.

Our stainless steel threads work with millimeter precision for decades, not only when you grind your favorite grains like wheat, rye, or spelt, but also hard and large grains like corn, chickpeas, or beans.

A stainless steel thread is uncompromising quality from the first to the last minute of grinding – over decades!

The Milling Chamber Made of Solid Wood

In the milling chamber, the wood of the grain mill is subjected to the greatest strain. With great force, the grinding stone crushes the grain, which, due to the rotational movement of the stone, rubs against the outer sides, the walls of the milling chamber.

Wear of the milling chamber can get into your flour – therefore, only solid, untreated, and especially hard wood is considered as material for us (except for stone carriers and grinding stone).

Recent findings show that natural beech wood has antibacterial properties! It is also well-known that wood has antistatic properties!

wood milling chamber hardly charges electrostatically during milling and therefore hardly transfers any electrostatic charges to the flour.

Many plastics, on the other hand, are highly chargeable electrostatically. A generally known, visible and tangible sign of discharge from plastics, for example, is the so-called electric shock/spark.

Almost all other mill manufacturers have opted for food-safe plastic – but we remain true to our tradition and prefer wood milling chambers – a rarity!

The cleaning of the milling chamber is not complex and only necessary from time to time. Using the mill regularly is the best thing you can do. Regular use also prevents moths or other pests from nesting in your mill.

Why Domestic Wood Instead of Plastic?

Wood is part of human history and is a living, organic material.

Real wood is nature and fulfills the desire for authenticity in an artificial world.

Anyone who owns a natural wood kitchen knows the advantages of wood. In a solid wood body, food stays fresh longer, bread does not start to mold, etc.

Recent studies have even attributed bactericidal properties to the natural material.

Germs cannot grow on natural wood surfaces.

Due to its cellular composition, with an almost unimaginably large surface area, wood has a strong hygroscopic effect. The associated dehydration creates a hostile environment for bacteria, leading to their death.
For several years now, “Wood & Hygiene” has been a research focus at the Institute for Wood Research at the University of Natural Resources and Life Sciences, Vienna.

The Design – The Philosophy of Design

In the 1970s, grain mills were still relatively unknown and accordingly, the selection was small.
Thus, the appearance of the mills matched the taste of the time and they fitted well into the typical living rooms and kitchens of Austria and Bavaria.

To fulfill a heartfelt wish of his wife Monika, Ing. Johann Thurner took it upon himself not only to build a technically perfect mill but also, in his eyes, a truly beautiful one. Accordingly, he put a lot of thought into the appearance of the mill:

What form suits a grain mill from Salzburg? It quickly became clear to him: It should be round, like the Salzburger Mozartkugel!

As a child and teenager, Johann Thurner was already a talented artist, and we owe the timelessly beautiful form of the MT series – the Original Salzburger Grain Mill – to his pencil.

For decades, it has been referred to by many as “the queen of mills” or sportily as “the Mercedes among mills”.

However, not only taste but also budget plays a role in the choice of the mill.
The fact that round wooden parts with steel elements are significantly more expensive than square ones led us later to design a particularly price-friendly mill.
The mill AM 1 was the beginning, and the models MAX, and MAX SPECIAL followed.

Good design is more than just shaping, more than a creative solution for technical, aesthetic, and functional requirements.

Today, good design also includes sustainability and environmental friendliness.
