Calcium carbonate (CaCO₃) is a versatile mineral widely used in industries such as plastics, paints, paper, and construction. The production of high-quality calcium carbonate powder requires efficient grinding equipment that can achieve precise particle size distribution while maintaining low operational costs. Raymond mill technology has evolved significantly, offering advanced solutions for fine and ultra-fine grinding applications.
Producing consistent quality calcium carbonate powder involves several challenges: achieving desired fineness (from coarse 600μm to ultra-fine 5μm), maintaining energy efficiency, ensuring minimal contamination, and meeting environmental standards. Traditional grinding methods often fall short in addressing these requirements comprehensively.
Different applications demand specific particle size distributions. For instance, paper coating requires 90% of particles below 2μm, while plastic filler applications may accept 45-75μm ranges. This necessitates grinding equipment with precise classification capabilities.
Grinding operations typically account for 60-70% of total energy consumption in mineral processing. Advanced mills must optimize energy usage while maintaining throughput capacity.
Modern grinding systems incorporate several technological innovations to address the challenges of calcium carbonate processing:
High-efficiency classifiers ensure accurate particle size separation, preventing coarse particles from contaminating the final product. Turbine classifiers with adjustable rotor speeds enable real-time fineness control.
Advanced materials for grinding components significantly extend operational life. Hardened alloy rollers and grinding rings maintain performance consistency while reducing maintenance frequency.
For ultra-fine calcium carbonate production (325-2500 mesh), we recommend our SCM Ultrafine Mill series. This equipment represents the pinnacle of grinding technology, specifically designed for producing high-value fine powders.

Successful calcium carbonate grinding operations require attention to several critical factors:
Optimal moisture content (typically <1%) ensures efficient grinding and prevents material adhesion. Pre-drying systems may be necessary for high-moisture feedstocks.
Complete grinding systems should include feeding, grinding, classification, and collection components. Proper integration ensures smooth operation and consistent product quality.
Modern grinding systems must meet stringent environmental regulations. Our mills feature advanced pulse dust collectors with efficiency exceeding 99.9%, ensuring dust emissions remain below 20mg/m³. Noise levels are controlled below 75dB through comprehensive sound insulation measures.
The selection of grinding equipment significantly impacts operational economics. Our SCM and MTW series mills offer rapid return on investment through:
30-40% reduction in power consumption compared to conventional ball mills
Extended component life and quick-change systems minimize downtime
Increased throughput capacity per unit of floor space
