The China Cement Association recently published the Blue Book: Development Report of China's Cement Industry (2019–2020). The paper "Application Research on FuYuan Air-Bearing Blowers for Energy Saving and Noise Reduction in the Cement Industry", written by Weifang FuYuan Turbocharger Co., Ltd., was included in the Blue Book's "Equipment and Services" section.
The air-bearing centrifugal blower developed independently by Weifang FuYuan Turbocharger Co., Ltd. integrates core technologies including an air bearing, a high-efficiency centrifugal impeller, a high-speed permanent-magnet synchronous motor, a variable-frequency drive and cooling and filtration systems. Its advantages are high efficiency and energy saving; no vibration and low noise; no lubricating oil and no mechanical servicing; and a high degree of system integration with remote control capability. In the cement industry it is used for the rotary kiln, kiln-head primary air, and air supply to raw meal silos and precalciners. Customers estimate the energy saving at 20%–30% compared with conventional Roots blowers, a clear saving that has made the blower popular with customers.
It is now used in volume by major Chinese cement producers including Conch Group, BBMC Jidong, Shanshui (Sunnsy) Group, Jinyuan Cement and Mengxi Cement.
