Formally known as the MTW Series European-style Trapezium Mill, this machine serves as a modernized and industrialized upgrade to the traditional Raymond Mill. Its core positioning targets medium-to-large-scale production lines for non-metallic mineral powder processing. Its objective is to consistently produce fine powders ranging from 80 to 400 mesh (approximately 0.038–0.18 mm) with lower unit energy consumption and enhanced operational reliability.
Simply put, it currently stands as the primary workhorse for processing medium-hardness materials such as limestone and calcite.
Patented technology, with an Inner automatic thin-oil lubricating system, and a long oil change cycle.
Employs an integrated bevel gear transmission system, replacing the traditional reducer-plus-coupling structure. This design results in a more compact transmission layout and significantly lower noise levels.
The core bearings utilize a thin oil lubrication system (as opposed to grease lubrication). This system offers superior heat dissipation and lower frictional resistance, thereby substantially extending the service life of both the bearings and the gears.
Features a unique curved air duct design that minimizes air resistance. When combined with a high-efficiency powder classifier, this design reduces energy consumption by approximately 20–30% compared to traditional Raymond Mills.
• Machine Positioning: Classified as a medium-speed mill, it occupies an intermediate position between high-speed impact mills and low-speed ball mills. It is primarily utilized to grind materials of medium hardness (Mohs hardness ≤ 7) into fine powders ranging from 80 to 400 mesh (approximately 0.038–0.18 mm). It serves as a versatile, core piece of equipment across various sectors, including building materials, chemical processing, and power plant desulfurization.
• Working Principle: Material is scooped up by scraper blades and fed into the space between the grinding rollers and the grinding ring, where it is pulverized through a process of rolling compression (rather than impact). The resulting powder rises along with the airflow and undergoes classification within a powder separator; coarse particles fall back down for further grinding, while the qualified fine powder is collected.
