Gypsum is a versatile mineral used in construction materials, cement additives, fertilizers, and even food and pharmaceuticals. To meet these diverse demands, it must often be ground into fine powders in the 200–400 mesh range. Selecting the right mill can make a major difference in efficiency, cost, and product quality. Liming Heavy Industry offers three strong options: the classic Raymond Mill, the MTW European Trapezium Mill, and the LM Vertical Roller Mill.

Raymond Mill – Reliable for Basic Needs

This long-established machine is suited for small to medium gypsum plants producing 200–325 mesh powders. With straightforward design, modest investment, and simple upkeep, it remains a dependable choice. Its centrifugal grinding rollers ensure steady output, though precision at finer ranges above 325 mesh is somewhat limited.

MTW European Trapezium Mill – Modernized Performance

An evolution of the traditional Raymond mill, the MTW model delivers better grinding efficiency, longer component life, and improved classification. With a bevel gear drive, thin-oil lubrication, and optimized blade design, it handles 200–400 mesh requirements with ease. Its efficient dust collection and low noise levels also make it a more environmentally friendly option.

LM Vertical Mill – High Capacity and Energy Saving

For large-scale gypsum production, the LM vertical roller mill offers clear advantages. It integrates drying, grinding, and classifying in one vertical structure, reducing both energy costs and floor space. The built-in hot air system allows effective processing of gypsum with higher moisture, making it well-suited for plants that require drying and grinding in a single step.

Conclusion

The choice depends on scale and goals: Raymond for cost-conscious smaller operations, MTW for higher precision and efficiency, and LM vertical for high-volume, energy-efficient production. By matching the mill to production needs, gypsum manufacturers can ensure consistent quality and stronger profitability.
