BLOWERS AND COMPRESSORS: OPTIMAL SOLUTIONS FOR THE CEMENT AND LIME INDUSTRY FROM AERZEN

AERZEN understands that safety is the top priority for the most challenging applications in cement plant operations. That’s why AERZEN’s blowers, vane compressors, and screw compressors for the cement industry are built to the highest standards, ensuring safe and reliable performance in the demanding and harsh environment of cement production.

Utilizing AERZEN Technology in the Cement Industry

With an experienced team of experts, AERZEN is ready to provide a comprehensive solution package that addresses every need and challenge your cement production system may encounter. Below are key applications where AERZEN technology has been successfully implemented:

Application 1: Pneumatic Transport from Raw Mill to Raw Meal Silo

AERZEN blowers are designed to ensure continuous airflow and stable pressure, preventing pipe blockages caused by uneven material flow.

Application 2: Raw Meal Silo Homogenization

AERZEN blowers offer flexible operation, suitable for various homogenization systems, ensuring optimal performance in pulse, continuous flow, or time-based operating modes.

Application 3: Pneumatic Transport from Raw Meal Silo to Preheater Tower or Kiln

AERZEN’s Delta Hybrid units provide superior energy efficiency for this critical application in high-dust environments. The Delta Hybrid models are equipped with electronic control systems and remote data transmission capabilities.

Application 4: Pneumatic Transport of Coal or Alternative Fuels

AERZEN’s Delta or Delta Hybrid blowers are ideal for this application, depending on operational data and fuel type. Upon request, AERZEN can certify all machines according to ATEX regulations to ensure safety in explosive environments.

Application 5: Gas Supply

AERZEN’s Delta Blower and Delta Hybrid are the perfect solutions for this critical application in cement plants. All machines are equipped with Variable Frequency Drives (VFD) to ensure reliable control of airflow and flame size in the combustion chamber, resulting in high-quality clinker production.

Application 6: Pneumatic Transport from Cement Mill to Cement Silo

The Delta Blower, Hybrid, or Screw compressors are ideal solutions for this demanding application, depending on the distance and pipe size. AERZEN provides the most suitable machine to ensure continuous material flow and prevent pipe blockages.

Application 7: Cement Silo Fluidization

AERZEN offers a unique option for standardizing models in this application, helping the plant optimize resources by using similar machines for homogenization and fluidization. The best selection is always made based on energy efficiency and machine capacity according to operational requirements.

Application 8: Cement Packaging

AERZEN blowers are the best choice for this application, providing high airflow and stable pressure to ensure that the cement loading system into trucks operates smoothly.

Two main methods of cement production:

The dry method is the most common and widely used method for cement production. In this method, raw materials such as chalk, limestone, silica sand, clay, and shale undergo several stages of crushing until they are reduced to a diameter of three inches or less. Next, other components like iron ore are mixed with the crushed stone, and this mixture is fed into a slightly inclined cement kiln, where it is heated at extremely high temperatures. As the mixture moves down from the higher end of the kiln to the lower end, the heat burns off some of the materials into gases. The remaining elements then fuse together, forming a material called clinker. The clinker exits the kiln, cools down, and is ground into an ultra-fine powder, which can be loaded onto trucks and transported to concrete suppliers.

The wet method is similar to the dry method, with the only difference being that limestone and other raw materials are mixed with water before being fed into the kiln. This method consumes more energy than the dry method.
