Centrifugal Fans • Industries
The cement industry is one of the sectors with the most demanding operating conditions for process air technology.
POLLRICH centrifugal fans are up to these challenges. In cement plants, extreme temperatures, abrasive dusts and corrosive gases prevail, which quickly push conventional fans to their limits.
POLLRICH therefore relies on robust designs and special wear protection systems. Wear-resistant materials and coatings protect the impellers and housings from abrasion and significantly increase the service life of the fans. This is how we ensure reliable operation and minimize your maintenance costs.
POLLRICH has many years of experience in the development and production of centrifugal fans for the cement industry. Our experts are familiar with the harsh operating conditions in cement plants and will provide you with competent consulting on the selection of the optimal fan for your application.

Which impeller types are used by POLLRICH in their centrifugal fans for the cement industry, and what are the advantages of these?
Depending on the application, different impeller types are used, e.g. backward-curved impellers for high efficiencies when conveying hot gases or radial impellers with open blades for transporting dust-laden gases.
How are POLLRICH centrifugal fans protected against abrasive media in the cement industry?
We use a variety of wear protection measures, such as wear-resistant linings made of Hardox steel, ceramic coatings or hard metal plating on the impeller blades.
Which storage concepts are used for POLLRICH centrifugal fans in the cement industry?
Depending on the requirements and size of the fan, sleeve bearings, roller bearings or magnetic bearings are used. The bearing is selected to withstand the high temperatures and dust loads in the cement industry.
How does POLLRICH guarantee the tightness of the fans when conveying dust-laden gases?
We use special sealing systems, such as labyrinth seals, stuffing box packings or mechanical seals, to prevent dust from entering the bearings and the housing.
Which options for speed control does POLLRICH offer for centrifugal fans used in the cement industry?
Frequency inverters, tap changers or hydraulic couplings can be used for speed control. The choice of the optimal system depends on the requirements of the plant.
How are POLLRICH centrifugal fans maintained in the cement industry?
In addition to regular inspections and maintenance work, such as lubricating the bearings and checking the seals, we offer a range of predictive maintenance solutions to detect potential damage at an early stage and avoid downtime.
What options does POLLRICH offer for reducing noise emissions from centrifugal fans in the cement industry?
We offer various soundproofing measures, such as silencers, sound-absorbing enclosures and vibration-damping installation devices. We also optimize the flow control in the fans to minimize noise.
Which requirements do POLLRICH centrifugal fans have to fulfill in the cement industry with regard to explosion protection?
Depending on the location and the materials used, the fans must meet the requirements of the ATEX guidelines. POLLRICH offers ATEX-certified fans in various device categories.
How does POLLRICH take energy efficiency into account when developing centrifugal fans for the cement industry?
We rely on aerodynamically optimized impellers and housings to maximize fan efficiency and minimize energy consumption. We also offer energy-efficient drive systems.
What possibilities for digitization does POLLRICH offer for centrifugal fans in the cement industry?
Our fans can be equipped with various sensors and control systems to enable continuous monitoring and control of operating parameters. We also offer digital solutions for remote maintenance and monitoring.
We realize efficient and innovative centrifugal fans for our customers from the respective industries according to our motto “Living Productivity”. With our extensive experience and expert knowledge and using all of our expertise, we produce durable and reliable products and support your company with customer-centric service to keep your production processes running.
