Background Introduction

In the chemical, building materials, rubber and plastic industries, light calcium carbonate (light calcium) is an important filler and reinforcing agent, and its quality directly affects the performance of the final product. However, due to its unique physical properties - high hygroscopicity and adhesion, traditional screening equipment often faces problems such as clogging and agglomeration when processing light calcium carbonate, which seriously affects production efficiency and product quality.

Problem Analysis

1. Blockage phenomenon: Light calcium carbonate powder is easy to block the screen due to electrostatic adsorption and adhesion between particles during the screening process, resulting in a significant decrease in screening efficiency.

2. Low screening accuracy: Ordinary vibrating screens are difficult to accurately control the screening particle size and are difficult to meet the requirements of the high-end market for particle size uniformity.

3. Limited production capacity: The blockage problem directly slows down the screening speed and affects the overall production capacity.

Solution: Application of ultrasonic vibrating screen

To solve the above problems, a light calcium carbonate production enterprise introduced ultrasonic vibrating screen for screening operations, achieving significant technical upgrades and efficiency improvements.

Working principle of ultrasonic vibrating screen: The device forms high-frequency and low-amplitude vibration waves on the screen through the built-in high-frequency ultrasonic transducer. This special vibration characteristic can not only effectively inhibit the adhesion of materials, but also perform secondary crushing of materials that have been electrostatically adhered into agglomerates, thereby significantly improving screening efficiency and screening quality.

Implementation effect

1. Screening accuracy is significantly improved: Ultrasonic vibrating screens can easily handle the screening of ultrafine powder materials up to 625 mesh, far exceeding the screening capacity of ordinary vibrating screens, ensuring the uniformity of particle size and high quality of the product.

2. The screen cleaning effect is significant: high-frequency and low-amplitude vibration effectively prevents the blockage of the screen holes, reduces the frequency of cleaning the screen, and increases the service life of the screen and production continuity.

3. The output is greatly increased: due to the solution of the blockage problem, the screening speed is significantly accelerated. Compared with the traditional rotary vibrating screen, the output of the ultrasonic vibrating screen is increased by 0.5-10 times, which greatly improves the production efficiency.

4. Maintain material properties: During the entire screening process, the physical and chemical properties of light calcium carbonate remain unchanged, ensuring the quality stability of the final product.

Conclusion

By introducing the ultrasonic vibrating screen, the light calcium carbonate production enterprise successfully solved the problems faced by traditional screening equipment, such as blockage, low screening accuracy, and limited production capacity, and achieved a comprehensive upgrade of the screening process. This successful case not only improved the company's production efficiency and product quality, but also provided valuable experience and reference for the same industry. With its excellent performance and wide application prospects, the ultrasonic vibrating screen is gradually becoming the preferred equipment for screening difficult-to-screen materials such as light calcium carbonate.
