75 years of KSL staubtechnik

KSL is celebrating a special company anniversary today. 75 years ago, on August 1st, 1949, KSL was founded by Konrad Schumacher in Lauingen. A few years earlier, his father had left him and his two brothers a limestone quarry in Haunsheim near the Swabian Alb, where limestone was mined and processed into fillers for the construction industry. Konrad Schumacher quickly realized, however, that this business was not particularly profitable and so he teamed up with FOGRA and developed the world’s first anti set-off powder (K4/15) in 1951.

The idea behind was simple: using classic mechanical processing technology (grinding, sieving, air-separation, mixing), to develop a powder which particles all have approximately the same diameter in order to enable efficient sheet separation in sheet-fed offset printing. This development was the starting signal for a success story that continues until today. From the 1970s onwards, his son and successor as managing director, Michael Schumacher, developed KSL into a global supplier of high-quality separation powders made from different materials for various industrial purposes. In addition to the printing industry, KSL today also supplies leading manufacturers of e.g. glass and film applications.

Thanks to our 75 years of experience, our separating powders can still guarantee an incomparably precise and consistent particle size distribution. Dr. Rupert Stadler, managing director since 2010 and now also managing owner of KSL, continues to focus on the quality of KSL products: “We want to maintain our status as the quality leader for separation powders and technical dusts. To achieve this, we care for our machinery just as well as our QM system, pay attention to stable processes and thus consistent products, and at the same time react flexibly to the wishes and requirements of our customers.”

We would like to thank our decades-long customers for their long-standing loyalty as well as our new customers for their trust. Our aim and ambition is to keep on working towards mutually successful collaborations in the future.
