A micro classifier for dolomite in China refers to a small-scale or laboratory-sized classification system used to separate dolomite particles based on size, density, or other properties. Dolomite (CaMg(CO₃)₂) is an important industrial mineral used in construction, agriculture, ceramics, and steel production.
Key Considerations for a Micro Classifier for Dolomite in China:
1. Classification Principle
– Air Classification: Uses airflow to separate fine dolomite particles (e.g., for fillers or chemical processing).
– Wet Classification: Uses water-based methods (e.g., hydrocyclones) for coarser separation.
– Screening: Mechanical sieving for larger particle size fractions.
2. Applications in China
– Construction Materials: Fine dolomite powder for cement and asphalt modifiers.
– Agriculture: Soil pH adjustment and magnesium supplements.
– Chemical Industry: High-purity dolomite for magnesium extraction.
3. Chinese Manufacturers & Suppliers
– Companies like Hosokawa Alpine, HCM Machinery (Guilin Hongcheng), and local firms produce micro classifiers suitable for dolomite processing.
– Look for suppliers specializing in:
– Jet mills (for ultrafine classification).
– Air classifiers (for dry powder separation).
4. Technical Specifications
– Particle size range: 1–100 µm (adjustable based on classifier type).
– Capacity: Small lab-scale (~1–50 kg/h) to pilot-scale (~100–500 kg/h).
5. Challenges & Solutions
– Dust control (use closed-loop systems).
– Moisture sensitivity (pre-drying may be required).
