‌1. Raymond Mill Series: Redefining Efficiency in Coarse-to-Medium Grinding‌

GUIKUANG’s Raymond Mill series (5R-7R models) sets new benchmarks for ‌high-volume, low-energy grinding‌ of non-metallic minerals (80-400 mesh).

‌Core Innovations:‌

‌Enhanced Grinding Structure‌:

Multi-layer high-chromium alloy grinding rollers paired with optimized curved grinding rings increase contact area by 35%, achieving a ‌325-mesh output capacity of 25 tons/hour‌ (40% higher than conventional mills).

Intelligent pressure control adjusts roller force in real-time, maintaining product consistency even with fluctuating ore hardness (MoHS ≤7).

‌Smart Thermal Management‌:

Temperature sensors and airflow regulators stabilize grinding zones at 60-80°C, reducing moisture content in materials like limestone and bentonite to ‌<0.5%‌, while preventing overheating-induced degradation. ‌Energy-Saving Design‌: Motors coupled with frequency converters cut power consumption to ‌0.8 kWh/ton‌ (325 mesh), slashing operational costs by 25%. Closed-circuit pulse dust collection ensures ‌dust emissions <15 mg/m³‌, complying with EPA and EU industrial standards. ‌Applications‌: Ideal for calcium carbonate, barite, gypsum, and fly ash processing in cement, paint, and agriculture sectors. ‌2. Sand-Powder Integrated Mill: Dual-Mode Processing for Resource Maximization‌ GUIKUANG’s groundbreaking ‌Sand-Powder Integrated Mill‌ revolutionizes material utilization by producing ‌0-3mm high-quality mechanism sand and 80-400 mesh powder simultaneously‌, eliminating the need for separate crushing/grinding lines. ‌Breakthrough Technologies:‌ ‌Hybrid Grinding System‌: Modular design integrates vertical roller pre-grinding and grinding mill fine-tuning, enabling rapid switching between sand and powder modes in ‌<30 minutes‌. Adjustable classifier rotor speeds (1,200-4,500 rpm) achieve precise particle distribution, with sand gradation meeting ‌ISO 14688-1:2017 standards‌ and powder uniformity (D97 deviation <2%). ‌Eco-Friendly Operation‌: Water-cooled grinding chambers and noise-dampening enclosures reduce operational noise to ‌≤80 dB‌, while negative-pressure dust control maintains workshop air quality (PM2.5 <50 µg/m³). ‌Cost Efficiency‌: Shared power systems and centralized automation reduce infrastructure investment by 40%, with a compact footprint 50% smaller than traditional dual-line setups. ‌Applications‌: Perfect for aggregate plants, glass sand production, and industrial byproduct recycling (e.g., slag, quartz tailings). ‌3. Calcium Hydroxide (Hydrated Lime) Production Line: Precision Engineering for High-Purity Applications‌ GUIKUANG’s dedicated ‌Calcium Hydroxide Processing System‌ combines digestion, grinding, and classification into a seamless, automated workflow, delivering pharmaceutical/food-grade hydrated lime with ‌>95% active Ca(OH)₂ content‌.

‌Key Advancements:‌

‌Dual-Temperature Zone Digestion Technology‌:

Precision-controlled steam injection (120-150°C) and water-calcium ratio adjustment (0.7-1.2) minimize free calcium oxide residue to ‌<0.3%‌, enhancing product reactivity and shelf life. ‌Ultra-Fine Grinding & Classification‌: Grinding rollers liners produce ‌325-mesh powder at 99.5% pass rate‌ (D50 ≤10 µm), while driven turbo classifiers ensure ±0.5% particle size stability. ‌Closed-Loop Purity Control‌: Nitrogen-shielded milling and packaging systems prevent carbonation, maintaining pH consistency (12.4±0.2) and whiteness ≥92% (Hunter scale). Real-time impurity detection via XRF sensors triggers automatic process adjustments, ensuring compliance with ‌USP/FCC/EP standards‌ for food/pharma applications. ‌Output & Efficiency‌: Capacity: 8-15 tons/hour (adjustable based on fineness) Energy consumption: <55 kWh/ton (325 mesh) Labor reduction: Fully automated operation cuts manual intervention by 70%. ‌Unified Advantages of the GUIKUANG Milling Family‌ ‌Smart Manufacturing Ecosystem‌: All equipment integrates‌, enabling remote monitoring, predictive maintenance (90% fault pre-detection accuracy), and AI-driven process optimization. Cloud-based data analytics provide actionable insights, boosting overall equipment effectiveness (OEE) to ‌≥93%‌ and reducing unplanned downtime to <5 hours/year. ‌Sustainability Leadership‌: Heat recovery systems capture 85% of waste thermal energy for pre-drying raw materials, lowering carbon footprint by 1.2 tons CO₂/1000 tons product. 98% recyclable steel construction and ISO 14001-certified manufacturing processes support circular economy goals. ‌Global Service Network‌: Customizable retrofitting packages modernize legacy mills within 30 days, ensuring compatibility with Siemens/ABB PLCs. ‌Why Choose Guikuang?‌ With ‌300+ successful installations‌ across 50+ countries—including lithium hydroxide projects for CATL/BYD and pharmaceutical-grade lime lines for Bayer—GUIKUANG combines cutting-edge engineering with localized service expertise.
