Cement industry

Individual, innovative, reliable: the industry relies on Lechler.

Every cement plant has its own challenges. In processes with nozzle applications, extreme environmental conditions prevail. Here, the benefits of Lechler nozzles are clear as they are made of highly resistant ceramic materials with minimal wear. A powerful gas treatment offers a variety of approaches to reduce costs and increase efficiency. With an international team of engineers and process engineers, Lechler develops individual solutions and adapts them to the challenges. What are the potentials of your plant? Let's find out together.

Lechler applications in the cement industry at a glance

Lechler Applications at a glance Injection of water to stabilize the grinding bed and to optimize the grinding process. Precise cooling and conditioning of hot flue gases creates stable outlet conditions for the safe and efficient operation of downstream plant components. Pre-cooling to protect downstream plant components and reduce the amount of operating gas. Injection for compensation of temperature peaks or additional cooling before the downcomer duct. SNCR process for the reduction of nitrogen oxides and compliance with the legal limit values through powerful denitrification systems in various configurations. Cooling of partial gas flow for the safe and efficient operation of the downstream plant components. Controllable and multi-stage injection to ensure precise SNCR denitrification for plants with optimal temperature range in the rotating kiln. Gas cooling in or after the clinker cooler to optimize, protect and improve the efficiency of the downstream plant components Injected water lowers the temperature in the mill.
