Solutions for the
cement, lime and gypsum industry

In the cement, lime and gypsum industries, high temperatures, constant load changes and abrasive dusts place extreme demands on process air technology and system components. New decarbonisation technologies require innovative solutions for fans and their accessories. Venti Oelde develops robust, low-noise and durable fans that reliably ensure process stability, efficiency and high availability even in continuous operation and is a solution partner in the development of pioneering processes.

Process-safe fans
for extreme conditions

Venti Oelde develops fans for the cement, lime and gypsum industries that operate reliably and consistently even under extreme conditions. Robust designs for continuous operation reliably handle high-temperature gas environments, high dust loads and abrasive media – even under highly variable loads and demanding process conditions.

Our solutions combine hot gas resistance and abrasion protection with precise flow control for process stabilisation. Energy-optimised gas flow enables significant energy and, consequently, greenhouse gas savings, whilst low noise emissions further enhance operational performance.

As a technology partner for innovative projects, Venti Oelde combines decades of experience with modern development tools such as CFD analyses and FEM calculations. This results in fans, filter and conveying systems that are optimally designed to reliably meet both today’s requirements and future concepts for climate-friendly cement production – for example in the following applications and process areas:

Core components of our solutions

Dedusting Technologies


Process fans and filter systems with integrated cyclone pre-separation. Separation of highly abrasive mineral dusts using particularly durable filter media, including robust wear protection and reliable cleaning – even with high dust loads.
Our filter systems are already capable of meeting the requirements for future green cement production processes, thereby optimally preparing the flue gas for downstream CCS and CCU processes.

Sorting & Seperating


Venti Oelde separator fans are available with various wear-resistant linings, which are selected according to the composition of the dust.

Cooling icon

Cooling Systems


Targeted cooling of units, drives and process zones through energy-optimised airflow. Essential for temperature control within the kiln and its peripheral areas.
Venti Oelde clinker cooler fans ensure efficient and stable operation of the clinker cooler.
Specially designed high-pressure fans are used as combustion air fans.

Convey icon

Conveyance Solutions


Venti Oelde supplies large-scale process fans which, in the case of raw mill and kiln exhaust fans, convey tonnes of material in the process gas. Depending on the project, special wear protection is provided. As with all fans, the utmost attention is paid to efficiency and durability.

Over 1000 cement plants worldwide operate fans from Venti Oelde!
