On June 21, 2022, Shaanxi Hongsishang New Materials congratulated Guilin Raytek Mining Machinery Co., Ltd. on the successful completion of the signing and plaque-unveiling ceremony for cooperation with the Suzhou Non-Metallic Minerals Institute, the Xianyang Non-Metallic Minerals Institute, and Guangxi University. Hongsishang New Materials purchased Guilin Raytek Mining Machinery Co., Ltd.’s extra-large new-type pendulum grinding mill HD1900B (Raymond mill), extra-large pendulum grinding mill HD2150 (Raymond mill), as well as the new integrated sand and powder machine HDD1900B, which is currently being installed. The new-generation extra-large new-type pendulum grinding mill HD1900B is an innovative and optimized best-selling model of Guilin Raytek Mining Machinery Co., Ltd. The technical features of this model are very significant, including an innovative main unit structure and a “maintenance-free” grinding roller assembly, achieving increased output and reduced energy consumption. Taking Hongsishang New Materials as an example, when processing heavy calcium powder at 200 mesh, the output can reach more than 20 tons per hour. Compared with traditional pendulum grinding mills of the same model, the output is increased by more than 30%. The new-generation integrated sand and powder machine HDD1900B is a star product of Guilin Raytek Mining Machinery Co., Ltd. Without changing the power of the grinding mill, it realizes the simultaneous production of sand and powder. Compared with traditional pendulum grinding mills (Raymond mills), while producing fine powder, it also produces sand particles at 1.5 times the output of fine powder. Compared with the sand output of current domestic sand-powder machines, the sand particle output is increased by 50%. It has the advantages of low energy consumption, high output, and high cost performance. Pendulum grinding mills (Raymond mills) are indispensable grinding equipment for the development of various industries and non-metallic minerals in China. In recent years, Guilin Raytek Mining Machinery Co., Ltd. has continued to increase its efforts in technological innovation, promoting product upgrading and replacement, and rapidly developing toward personalization, automation, and intelligence. The company has quickly enhanced its technical strength, capability, and reputation, making every effort to build the “China Grinding Mill” brand.
