Formally known as the Vertical Roller Mill, this equipment acts as an advanced and high-capacity upgrading solution for conventional grinding equipment. Its core positioning focuses on large-scale industrial grinding projects for minerals, cement raw materials and solid materials. Its objective is to stably produce diversified powder products from 80 to 1250 mesh (approximately 0.01–0.18 mm), featuring compact structure and comprehensive energy-saving performance.
Simply put, it has become the mainstream core equipment for large-volume ultra-fine grinding of hard and medium-hard materials like clinker, slag and iron ore.
• Equipment Type: Vertical grinding mill (positioned between medium-speed grinding equipment and heavy-duty ball mills).
• Product Fineness: 80–1250 mesh (approx. 0.01–0.18 mm), freely adjustable.
• Core Value: While maintaining large hourly output, the equipment realizes overall energy saving and stable operation through integrated structural design.
• Applicable Materials: Cement clinker, slag, iron ore, limestone, coal powder, quartz sand, bauxite, etc.
• Industry Applications: Cement raw material grinding, industrial slag powder production, mine ore processing, thermal power coal pulverizing and large-scale building materials deep processing.
Patented technology, with an Inner automatic thin-oil lubricating system, and a long oil change cycle.
The system operates under negative pressure, ensuring there is no dust leakage. The dust removal efficiency of the bag dust collector is as high as 99.9%.
Low energy consumption results in saving 30%-50% of electricity compared to traditional ball mills. The roller plate is wear-resistant and has a long lifespan.
It occupies a small area and saves construction costs. It is suitable for materials with different humidity levels and can dry materials with a maximum humidity of 15%.
• Machine Positioning: Classified as a large-scale vertical roller mill, it occupies a high-efficiency position between medium-speed grinding mills and traditional ball mills. It is primarily utilized to grind materials of varying hardness into fine and ultra-fine powders ranging from 80 to 1250 mesh (approximately 0.01–0.18 mm). It serves as a versatile, core piece of equipment across various sectors, including cement production, mineral processing, and power plant coal pulverization.
• Working Principle: Materials are fed into the center of the grinding table and move outward under centrifugal force, then are crushed and ground between the rotating table and the hydraulic-pressed grinding rollers. The ground material is carried upward by hot gas flow into the classifier for sorting; qualified fine powder is collected, while coarse particles fall back to the grinding table for regrinding.
