economical reliable resource-saving. In 1899, Polysius put Europe's first rotary kiln into operation. In those days, rotary kilns were a maximum of 2 m in diameter and 20 m in length, managing daily outputs of 30 to 50 tonnes of cement clinker per day. Nowadays, production capacities of 10,000 tonnes per day are nothing unusual.
