Clinker Cooler Modifications

After 70 successful years in the clinker cooler business as a technologically leading company, Claudius Peters is the reliable partner for conversions and modifications. 

We offer the complete range of services, from the replacement of individual plant components, the replacement of only the core parts, to the complete replacement of coolers.

In close coordination and cooperation with our customers, we develop the best possible solution for the respective application.

A Cooler Modification with or without a capacity upgrade will include design upgrades with the focus will be on three targets:
Efficiency & Energy Consumption
Extended life time design
100% availability

Finding the right strategy for a cooler upgrade implies that all effects in between the different pyro process steps need to be taken into consideration.

If you plan to upgrade the clinker capacity of the pyro line or want to evaluate a system upgrade of the cooler by a Waste Heat Recovery system, Claudius Peters is your partner with a precise understanding how these changes impact the interfaces for the overall process.  

Through close partnerships in the market Claudius Peters can offer you the complete cooler package for the required modifications of your existing cooler including exhaust air or water injection system, kiln hood and sealing as well as the providing a new burner platform etc.

Capacity Increase

Upgrading your clinker production rate often surpasses the capacity limits of the existing clinker cooler and it is needed to adapt or even replace the existing system. 

Separate cooler components or even the new 5th Generation ETA Cooler are available to be embedded in your plant environment. The use of latest technologies – if required - like i.e. 3D-Laser Scan technology, Claudius Peters ensures smooth project execution and a short installation time.


Cooler drive systems have undergone major development in recent decades.

From the electromechanical drive (1950...1970s) - with fixed stroke lengths to the hydraulic differential drive (1970s...1980s) with limit switches to the hydraulic proportional drive (since 1990s) with continuous displacement transducers, the possible operating problems (e.g. availability) can be counteracted with different conversion packages.

HE Module

Claudius Peters supplies all his coolers since years with a static grate in the inlet zone of the clinker cooler, the so-called HE module. In recent years, the HE module has been developed to achieve a long service life with low-pressure losses, reducing operating costs to a minimum.

Claudius Peters Clinker Crushers

The hammer crusher is the standard solution for crushing clinker. Claudius Peters has been supplying hammer crushers worldwide for capacities up to 6000 t/d since 1955.

Claudius Peters developed the roller crusher for use in clinker coolers at the end of the 1970s. Today, the roller crusher is the standard unit for crushing the clinker inside the clinker cooler. Due to the slow speed, the roller crusher produces a lower dust load and less wear inside the cooler and on the crusher itself.
