Grinding Equipment for Processing Quartz Stone: Process Characteristics and Principles of Ultrafine Grinding

Quartz crystals rank second only to diamonds in natural hardness. With their four key advantages—scratch-resistant, non-staining, durable, and non-combustible—they have emerged as an eco-friendly, innovative material for interior building decoration. Investors recognize the promising market outlook for quartz grinding machines but often struggle to identify which model can effectively tackle this “tough nut to crack.” Today, we introduce Shanghai ZENITH's LUM Ultra-Fine Vertical Mill, which can transform even quartz stone-hard materials into powder as soft as silk. Based on market demand and years of grinding mill production experience, Shanghai ZENITH built upon traditional vertical mill technology. By integrating advanced powder classification and grinding roller techniques, it created a national utility model patented product for ultra-fine dry powder processing that combines micron-level grinding, classification, and conveying. The LUM Ultra-Fine Vertical Mill excels at grinding highly hard and fine-grained materials. Its remarkable adaptability to quartz stone demonstrates its potential to significantly boost production and profitability for other non-metallic mineral processing enterprises.

Using Shanghai ZENITH's quartz stone vertical mill for quartz powder production consumes 20%-30% less electricity than traditional grinding machines. It also offers high output, excellent wear resistance, low noise, minimal dust emission, and a clean operating environment. The ground product features stable chemical composition, uniform particle size distribution, and adjustable fineness, enabling precise control over the desired quartz powder particle size and enhancing quartz grinding efficiency.

LUM Ultra-Fine Vertical Mill Structural Principle: Material enters via the reducer feeder and falls onto the central grinding disc. The main motor drives the reducer, rotating the grinding disc to generate centrifugal force that moves material toward the periphery. As material passes over the roller track on the grinding disc, it is crushed by the grinding rollers. Large lumps are crushed, and smaller particles move toward the mill disc edge. These particles are carried by airflow entering through the inlet to the classifier. Under the action of classifier blades, particles below the target size fall back to the mill disc for re-grinding. Particles meeting the standard pass through the classifier with the airflow into the pulse dust collector for collection. The collected powder is the finished product.
