Pneumatic conveying technology for Dyckerhoff

Pneumatic conveying technology features prominently in handling the flow of materials in the cement industry. Blowers convey the fine material in pipelines throughout the production process. The requirements for the availability of the assembled units are high, as production would come to a standstill without blower air. Dyckerhoff has used Aerzen solutions for decades in its Lengerich cement plant, convinced by the innovative approach to air compression.

Hot process air is one of the most important energy sources in a cement plant. Dyckerhoff uses fuel oil for heating up, and then switches to pulverised lignite which is blown into the rotary kiln by means of a burner lance. The lignite burns immediately. In its kilns, Dyckerhoff can also burn derived fuels like fluff, a fibrous and high-calorific mass that consists mainly of chlorine-free plastics.

1 Blower technology for fuel supply

Dyckerhoff also uses the principle of pneumatic conveying technology to supply the burner. Positive Displacement Blowers (GM 25, 304 to 1452 m³/h, 55 kW max) of the...
