Xinfeng Mini-Classroom---How to Address Excessive Noise from Centrifugal Fans in the Cement Industry?

What about the noise levels of centrifugal fans in the cement industry? When it comes to centrifugal fan equipment, everyone is quite familiar with it. Whether centrifugal fans or other types of centrifugal fans, they play an increasingly vital role in our social life, which is inseparable from the concept of energy conservation! How about the centrifugal fans used in the cement industry? What about the noise?

Centrifugal fans are the primary energy-consuming equipment in the cement industry. Energy conservation and environmental protection remain major trends and themes in the cement industry. The primary electrical equipment in cement plants—crushing machinery, ball mills, and centrifugal fans—account for the bulk of total electricity consumption. Centrifugal fans alone consume 20% of total power usage and constitute 30-35% of the plant's total installed capacity. Enhancing the environmental performance and energy efficiency of centrifugal fans holds significant practical importance for reducing cement production costs and strengthening corporate competitiveness.

Current Status and Applications of Centrifugal Fans in the Cement Industry: Vertical kilns utilize centrifugal fans for calcination air supply, offering advantages of low thermal consumption, minimal investment, and high efficiency. Centrifugal fans deliver robust exhaust performance and strong pressure adaptability, making them widely adopted for cement calcination air supply. For cement plant vertical kilns, required air pressure often fluctuates with changes in the material layer height within the kiln. The higher the material layer, the greater the required air pressure and volume, making the centrifugal fan's robust exhaust capability particularly well-suited to meet this demand.

What harm does noise cause? The noise generated by factory centrifugal fans during operation is complex, composed of sounds at various frequencies without periodicity. This not only disrupts production and processing management plans but also impairs employee physical and mental health, leading to reduced efficiency. How to address noise? Centrifugal fans equipped with installed noise reduction devices produce noticeable steam-driven noise during high-speed operation. To prevent sound diffusion without obstructing airflow, install silencers at the fan's air outlet to control steam-driven noise.

Installing soundproofing materials for noise reduction is a common technical measure in noise control projects. Utilizing various wall panels and prefabricated components as structural applications confines noise within a defined range, obstructing its propagation to ensure effective noise reduction.  Decorate walls or ceilings with sound-absorbing panels using acoustic materials, soundproof structures, or suspended systems. Apply acoustic materials—once mixed, they become fully integrated. Acoustic materials play a crucial role in sound absorption and noise reduction methods; select appropriate raw materials based on on-site noise source analysis.
