Raymond Mill Technical Specifications: Key Parameters for Efficient Powder Grinding

Introduction to Raymond Mill Technology

Raymond mill, a cornerstone in powder processing industries, is renowned for its precision grinding capabilities across minerals, chemicals, and construction materials. This article delves into the critical technical specifications that define high-performance Raymond mills, with insights from ZENITH’s 30+ years of engineering expertise in grinding solutions.

Core Design Principles

Modern Raymond mills integrate three fundamental components:

  1. Grinding Mechanism: Multi-layer grinding rings with synchronized roller pressure
  2. Classification System: Precision air separators for particle size control
  3. Material Handling: Optimized airflow paths for efficient powder collection

Critical Technical Parameters

1. Feed Size Capacity

Standard Raymond mills process materials with:

  • Maximum input size: ≤50mm (varies by model)
  • Ideal feed moisture: <6% for optimal grinding efficiency

2. Output Fineness Range

Advanced models achieve adjustable fineness:

  • Standard range: 30-325 mesh (0.045-0.6mm)
  • High-precision models: Up to 2500 mesh (5μm)

3. Production Capacity

Throughput varies by machine configuration:

Model Type Capacity Range Power Consumption
Small-scale 0.5-5 ton/h 45-75kW
Industrial 5-25 ton/h 132-315kW
Heavy-duty 25-45 ton/h 400-900kW
