History
Foundation and first achievements
The company was founded in Dessau: around Easter 1859, master locksmith Gottfried Polysius opened a workshop in Dessau with an apprentice and laid the foundations for today's company with his locksmith's shop and the manufacture of safes. On May 23, 1870, he founded G. Polysius iron foundery and engineering factory, which established itself in the then-young building materials industry with self-designed and powerful mills. Besides money cabinets, the company also produced drains and vibrating screens.
In addition to agricultural machinery, Polysius also produced grain mills, brewery and distillery equipment. He was particularly involved in the up-and-coming beet sugar industry. From then on, Polysius specialized in crushing and processing machines. After Polysius' death, his sons Otto and Max Polysius successfully continued the company.
