Cronus HGM series ultrafine ring roller mill delivers precision grinding from 300 to 3000 mesh. Engineered for non-metallic mineral processing with over 50 years of manufacturing excellence from Guilin Mining Machinery.
About Our Company
Shanghai Cronus Machinery Co., Ltd. is a wholly-owned subsidiary of Guilin Mining Machinery Co., Ltd. (formerly Guilin Mining Machinery Factory), founded in 1973. With over 50 years of equipment manufacturing history, we are one of the two major grinding equipment manufacturers designated by the former Ministry of Electrical and Mechanical Services of China, and a backbone enterprise of Guangxi's machinery industry.
Our company integrates R&D, design, production, and sales. We specialize in manufacturing Raymond mills, ultrafine ring roller mills (HGM series), vertical roller mills, hydrated lime production lines, and comprehensive mineral processing solutions. All products have passed ISO 9001:2008 and CE international quality system certifications.
Contact Us TodayThe HGM series ultrafine ring roller mill uses a multi-layer ring roller grinding mechanism to achieve ultra-fine powder production at 300-3000 mesh.
Raw materials are fed into the grinding chamber through a vibrating feeder. Materials smaller than 20mm are continuously and evenly delivered to the mill.
The material is ground between the grinding rollers and rings in multiple layers. The ring rollers rotate around the central shaft while spinning on their own axes, creating high-pressure grinding action.
Ground powder is carried by airflow to the classifier. The high-precision classifier separates fine powder (300-3000 mesh adjustable) from coarse particles, which are returned for re-grinding.
Qualified fine powder passes through the classifier and is collected by the cyclone collector and pulse dust collector. The final product is discharged through the discharge valve.
Our HGM series ring roller mills offer fineness from 300 to 3000 mesh, covering a wide range of production capacities for different industrial needs.
