Calcium carbonate powder is a cornerstone material across industries such as plastics, paints, pharmaceuticals, and construction. Achieving consistent particle size distribution (PSD) and ultra-fine grinding (down to 5μm) demands precision-engineered milling systems. This article explores how our cutting-edge grinding technologies—from coarse crushing to ultrafine classification—deliver unmatched efficiency, scalability, and sustainability for calcium carbonate processing.

A streamlined production line typically integrates:
Our SCM series consumes only 0.8-1.2kWh/kg for 1250 mesh powder—30% lower than conventional mills. LM vertical mills reduce power use by 35-50% via optimized grinding kinematics.
Smart classification systems (e.g., SCM’s vertical turbine classifier) ensure ≤±2% deviation in D50 values. Real-time particle analyzers feed data to automatic adjustment systems.
Hardened alloy rollers (HRC≥58) in MTW mills last 8,000+ hours in continuous CaCO3 processing. Modular designs enable roller replacement in under 4 hours.
Based on the absorption of advanced technologies of famous international corporations and 30 years’ experience in grinding mill production, SBM has launched the LM Vertical Grinding Mill which integrates five functions of crushing, grinding, powder selection, drying and material conveying. It is characterized by centralized technological process, small occupational area, low investment, high efficiency, energy conservation and environment protection.
SCM Ultrafine Grinding Mill is a new superfine powder (325-2500 mesh) production equipment developed through accumulating years of experience in grinding mill production, absorbing Swedish advanced machine manufacturing technology, and undergoing many years of tests and improvements. The SCM Ultrafine Grinding Mill is the result of combination of advanced Chinese and Swedish technologies. Meanwhile, it symbolizes the new development and new science in the grinding world.
LUM Ultrafine Vertical Grinding Mill is independently designed by SBM on the basis of years of experience in grinding mill production. LUM grinding mill adopts the latest Taiwan grinding roller technology and German powder separating technology. The ultrafine vertical grinding mill integrating ultrafine powder grinding, grading and transporting has become a better choice in the ultrafine powder grinding industry.
MRN Pendulous Hanging Grinding Mill represents the most advanced grinding processing technology. The brand-new structural design not only lowers the operation and maintenance cost, but also does well in environmental protection and finished product quality. It is available when processing the non-combustible, non-explosive brittle minerals products like limestone, calcite and marble, etc. MRN Pendulum mill is widely used in mining, building, power plant and coating industries.
