Cement solutions

Blowers and compressors designed for better solutions in cement applications

Cement blowers and compressors are vital in several cement plants operations. For instance, at the start of the cement manufacturing process, blowers convey materials both into and out of the kiln. Afterward, bulk transfer blowers convey the cement to various transport points, including loading the cement in and out of bulk containers, trucks, and railcars.

Depending on your cement plant’s operations, the specialists at AERZEN can tailor make a package offering you the solutions you need to address any challenges your system might be facing.

We understand how crucial cement applications safety is and how challenging it is to maintain. Fortunately, our engineers manufacture our blower systems, screw compressors, and rotary lobe compressors with the highest possible standards.

Doing so enables us to guarantee all our clients a safe and reliable operation that will not be limited, even in the high-demanding nature of cement applications.

Specific features for cement industry

Scheme of the production of cement by the dry process

There are two ways to manufacture cement. The dry method is the most common and popular cement manufacturing method. Here, raw materials like chalk, limestone, silica sand, clay, and slate undergo several crushing stages until they are three inches or less in diameter.

Next, other ingredients like iron ore are mixed with the crushed rock, and the mixture is put in a cement kiln, which, slightly tilted on an axis, heats them at an extremely high temperature.

As the mixture descends from the higher end of the kiln to the lower, the heat burns off certain materials as gases. The elements left behind then meld together, forming a material known as clinker.

The clinker exits the kiln, cools, and is ground into an extremely fine powder that you can load onto trucks and transport to concrete suppliers.

The wet method is similar to the first, with the only difference being that the limestone and other raw materials are mixed with water before being put in the kiln and the whole process consumes more energy than the dry process.

Improving the Coal-Feeding Conveying System in a Holcim Cement Plant


Holcim Colombia plant, located in Nobsa, two and a half hours from Bogota, has a capacity of about 3Mt/year of cement and 12% of the country’s market share, with high growth expected after 2015’s Lafarge Holcim joint venture.

Though AERZEN began operations in Colombia in 2008, in 2014, the company’s Application Sale Team identified an opportunity to upgrade the plant's Pfister system—the coal pneumatic conveying transport to the main burner.
