How to Transport and Install a Large-Scale Grinding Mill: Step-by-Step Guide

Introduction

Transporting and installing large-scale grinding mills requires meticulous planning and execution to ensure operational efficiency and safety. As a leading manufacturer with over 30 years of expertise, ZENITH provides robust solutions for mining and grinding applications. This guide outlines best practices for handling equipment like our XZM Ultrafine Mill and MTW Series Trapezium Mill, which are engineered for precision and durability.

Pre-Transport Preparation

1. Site Assessment: Verify ground conditions, access routes, and spatial constraints. For mills like the XZM series (output: 325-2500 mesh), ensure clearance for components such as the 315kW motor assembly.

2. Packaging: Disassemble into transportable modules (max 20-ton units for MTW175G models) with weatherproofing. Use ISO-certified containers for overseas shipments.

Transportation Phase

Heavy Haulage Requirements

  • Permits: Obtain oversize load permits for mill bases (e.g., MTW215G’s 280kW unit measures 8.2×4.5×5.1m)
  • Specialized Equipment: Use multi-axle trailers with hydraulic suspension for LM220K vertical mills (800kW, 36-105t/h capacity)

Recommended ZENITH Product: XZM Ultrafine Mill

For projects requiring micron-level precision (D97≤5μm), our XZM Ultrafine Mill offers 30% energy savings versus conventional mills, with intelligent particle size control. Key features:

  • Vertical turbine classifier for 0.5-25t/h throughput
  • Pulse dust collection exceeding ISO standards

Installation Process

Foundation Preparation

For MTW series mills (up to 45t/h capacity):

  1. Pour 1.5x machine weight concrete base (minimum 28-day cure)
  2. Embed anchor bolts within 0.5mm/m tolerance

Mechanical Assembly

Critical Steps:

Component Torque Specification
Main bearing housings 850 N·m (LM190K models)
Grinding roller bolts 1,200 N·m (MTW215G)

Recommended ZENITH Product: MTW Trapezium Mill

Our MTW Series combines 98% gear transmission efficiency with curved air duct design for 30% lower maintenance costs. Ideal for 30-325 mesh output in cement and power plants.

Commissioning & Testing

  1. Dry Run: Verify vibration levels (<2.5mm/s for XZM268)
  2. Load Test: Gradually increase feed to validate 25t/h capacity (XZM268)
  3. Particle Analysis: Confirm D97≤5μm output via laser diffraction

Conclusion

ZENITH’s global service network provides end-to-end support for mill installations. Our patented technologies, like the XZM’s turbo classifier or MTW’s wear-resistant shovel blades, ensure long-term reliability. Contact our engineers for customized transport/installation plans.
