Extended service life in the cement industry

Today, cement is manufactured in a continuous process in modern cement works from predominantly natural raw materials according to the dry process described below. In doing so, the systems achieve an output of 3,000 to 10,000 tons of clinker per day.

The materials (usually limestone, clay, and sand) are mined in quarries, precrushed in crushers and conveyed into the cement works. All raw materials are ground together in a raw mill. The raw mix produced thereby is then fired to so-called clinker in a rotary oven at temperatures of approx. 1450 °C. The clinker is then cooled down to a temperature of less than 200 °C in a cooler. Afterwards, the grey-brown granules produced are ground together with plaster or anhydrite to the finished product, cement, in a ball mill.

During the processing of coarse, ceramic materials, machine parts are subject to significant wear. An analysis of the wear parts is made; to combat wear,appropriate recommendations are developed for the component's design and materials of construction. Chilled iron, hardfacing materials, composite wear plates, composite casting and composite alloys utilised as necessary.
