Abstract: Non-metallic ores differ greatly in hardness and required powder fineness. This content sorts applicable capacity and mesh range of seven SBM grinding models to help mineral factories match proper equipment quickly.
Non-metallic minerals cover wide varieties including limestone, gypsum, coal, barite, calcium carbonate and bauxite. Different ores have distinct hardness, target powder fineness and annual production scale. Many buyers select equipment blindly and encounter insufficient capacity, unqualified fineness or excessive energy consumption. Seven series of SBM grinding mills cover all non-metallic ore processing requirements. We clarify applicable scenarios clearly as below:

LM Vertical Grinding Mill: Large-capacity coarse powder processing for limestone and coal, 20–400 mesh, maximum 700 t/h, first choice for large desulfurization and building material projects.
MTW European Trapezium Mill: Medium-small gypsum and regular limestone plants, 3–45 t/h, 0.038–1.6 mm, cost-effective option.
MTW6X Intelligent European Mill: Quicklime and moisture-sensitive materials with full oil lubrication and remote intelligent control system.
PMD Permanent Magnet Direct Drive Mill: Explosion-proof processing of coal and petroleum coke for carbon industry with 20%–30% energy saving.
LUM Ultrafine Vertical Mill: High-end ultrafine GCC production, 325–2500 mesh.
SCM Ultrafine Powder Mill: Ultrafine barite for drilling and low-output ultrafine powder processing.
LM-Y Vertical Pre-grinding Roller Mill: Integrated bauxite aggregate and fine powder output for refractory industry.
All mills adopt sealed negative-pressure dust removal to meet environmental standards. Original wear-resistant spare parts and one-stop service are available for all models. Buyers only need to provide processed material, target hourly capacity and required powder mesh size to get accurate model matching and avoid waste of equipment investment. Thousands of non-metallic mineral processing factories worldwide adopt complete SBM grinding production lines, covering building material, chemical, oilfield, refractory and carbon industries.
If you are unsure which grinding mill fits your raw material, send material name, annual output and required powder fineness via online consultation. Our engineers provide free model comparison tables, site layout plans and reference cases of nearby operating projects.
Summary (~50 words)
Choose LM vertical mill for large-capacity coarse powder; MTW/MTW6X for regular medium-small materials; LUM for ultrafine GCC; PMD for coal & carbon materials; LMSF for integrated sand & powder production.
FAQ
Q: Which mill should be chosen for 325 mesh limestone powder, LM or MTW?
A: Select LM vertical mill for annual output over 300,000 tons; MTW European mill for medium-small projects with annual output 50,000–200,000 tons.
Q: Which equipment produces 2000 mesh ultrafine GCC?
A: Dedicated LUM ultrafine vertical mill. Ordinary European mill cannot steadily produce 2000 mesh ultrafine powder.
Q: Why is PMD model preferred for coal powder preparation?
A: Permanent magnet direct drive saves power, and full explosion-proof protection fits long-term continuous operation of carbon and power plants.
