Calcite, one of the most common forms of calcium carbonate, is a crucial raw material in plastics, rubber, coatings, and papermaking. These sectors often demand ultra-fine powders in the 325–3000 mesh range, which calls for reliable grinding systems that combine high performance with low operating costs. Liming Heavy Industry provides two standout options: the LUM Ultrafine Vertical Roller Mill and the MW Series Micro Powder Mill.

The LUM ultrafine vertical mill is engineered for large-scale operations requiring fine and stable powder between 400–3000 mesh. By combining grinding, classification, and conveying into one compact system, it minimizes energy use while delivering consistent results. Its multi-head classifier ensures accurate fineness, while the roller design reduces wear, making it ideal for industries that demand precise particle size control and product stability.

For smaller businesses or those seeking a more flexible investment, the MW Micro Powder Mill offers an excellent balance between cost and performance. Capable of producing powders from 325 to 2500 mesh, it comes with a compact footprint and an advanced dust collection system. Despite its smaller scale, it ensures steady output quality and efficient energy use.

When it comes to overall cost, both mills provide strong long-term value. The LUM model, while requiring higher initial spending, offers lower energy consumption per ton and reduced maintenance downtime, making it the go-to choice for continuous mass production. The MW mill is better suited for companies focusing on customized output or moderate production needs.

Both models also meet strict environmental standards with integrated dust and noise control, ensuring clean, eco-friendly operation. In short, whether your priority is large-scale efficiency or cost-sensitive flexibility, Liming’s grinding solutions deliver dependable performance for today’s calcite powder market.
