Best Dolomite Grinding Mills for High-Quality Glass Production

Best Dolomite Grinding Mills for High-Quality Glass Production

Introduction

Dolomite is a critical raw material in glass manufacturing, requiring precise particle size distribution to ensure optimal melting properties and final product clarity. Selecting the right grinding mill significantly impacts production efficiency, energy consumption, and product quality. This article explores advanced dolomite grinding solutions with a focus on achieving the ultra-fine powders (45-5μm) essential for premium glass production.

Key Requirements for Glass-Grade Dolomite Powder

• Particle Uniformity: D97 ≤5μm with narrow size distribution
• Iron Content Control: ≤0.015% Fe₂O₃ to prevent coloration
• High Throughput: 5-25 ton/h for industrial-scale production
• Energy Efficiency: ≤30kWh/ton at 2500 mesh fineness

Advanced Grinding Technologies

1. Ultrafine Vertical Roller Mills

Modern vertical mills combine grinding and classification in a single unit, offering superior control over particle size distribution. Our SCM Ultrafine Mill series stands out with these features:

Technical Highlights:

• Precision Classification: Vertical turbine classifier achieves 99.9% separation efficiency
• Wear Resistance
• Closed-Circuit Design: Negative pressure operation prevents dust leakage (≤10mg/m³)

2. European-Type Trapezium Mills

For operations requiring coarser grinding (600-45μm) as a pre-processing stage, our MTW Series offers exceptional value:

• Curved air duct reduces energy loss by 15%
• Modular wear parts extend service intervals
• Integrated pulse dust collector meets ISO 8573-1 Class 0

Case Study: Glass Batch Optimization

A leading glass manufacturer achieved 18% energy reduction and 2.3% improvement in melting homogeneity by implementing our SCM1680 mill with these parameters:
