GUIKUANG Raymond Mill Technical Solution for 325-Mesh Calcite Powder Processing ‌Process Optimization

GUIKUANG’s Raymond mill integrates ‌multi-stage vortex classification‌ and ‌intelligent frequency control‌ to achieve precise 325-mesh (45μm) calcite powder production, with purity ≥98.5% and whiteness ≥95°, ideal for high-end coatings, plastics, and paper industries‌13. The system employs ‌dynamic pressure grinding‌ and ‌thermal energy recycling‌, reducing energy consumption by 20% while maintaining a stable output of 18-22 t/h.
‌Core Advantages‌
‌Precision Particle Control‌:
Adjustable grinding pressure (0.08-0.2MPa) and ‌turbo-classifier‌ (200-1200 rpm) ensure D97 deviation <2%, supporting flexible fineness adjustment from 80 to 2500 mesh. Optimized grinding trajectory minimizes over-grinding, achieving 99% powder yield for 325-mesh calcite. ‌Energy Efficiency‌: Frequency-controlled motors and ‌layered grinding technology‌ reduce power consumption to ≤15 kWh/t, meeting China’s Grade 1 energy standards. Heat recovery systems cut thermal loss by 25%, enabling direct processing of raw materials with ≤10% moisture. ‌Durability & Eco-Friendliness‌: High-manganese alloy rollers and grinding rings extend service life by 4× (up to 8,000 hours), reducing metal contamination to <0.005%. Closed-loop pulse dust removal ensures emissions ≤5 mg/m³ (CE-certified), with noise levels ≤78 dB. ‌Technical Validation‌ A Southeast Asian calcite project achieved ‌annual output of 600,000 tons‌ of 325-mesh powder, boosting productivity by 40% and reducing processing costs by $1.8/t. ‌Why Choose GUIKUANG?‌ With 52 years of expertise in mineral processing, GUIKUANG combines ‌intelligent grading‌, ‌ultra-low energy consumption‌, and ‌zero-pollution production‌ to deliver a 20% reduction in operational costs for 325-mesh calcite processing‌13. Its modular design and IoT remote monitoring further ensure 95% uptime, making it the optimal solution for sustainable, high-value mineral powder production.
