Introduction

This document provides an authoritative overview of the operational principles of Wirtgen milling machines, which are essential equipment in road construction and maintenance for removing pavement layers or the entire road surfaces.

Principles of Wirtgen Milling Machine Operation

Wirtgen milling machines work by using a rotating drum equipped with a large number of replaceable tungsten carbide-tipped milling bits. This drum rotates at speeds between 100-200 RPM, allowing it to effectively cut through materials up to 35 cm deep.

The key operational aspect is the rotation of the drum driven by diesel-powered engines ranging from 300 kW to 750 kW, depending on the model. The machine's working speed typically varies from 0.5 m/min to 10 m/min.

Cutting Precision

The precision is achieved through electrical control systems, maintaining a cutting accuracy of ±3 mm, ensuring a consistent milling depth across the pavement.

Mechanical Systems

The primary mechanical components consist of the milling drum, conveyor system, and the chassis.

• Milling Drum: Equipped with up to 300 replaceable cutting bits, ensuring efficient material removal.
• Conveyor System: Typically has a discharge capacity of up to 400 tons/hour, transporting the milled material to trucks.
• Chassis: Provides stability and can handle machines weighing between 15 to 50 tons.

Advanced Control Systems

Modern Wirtgen milling machines incorporate GPS-based control systems allowing for precise navigation and milling path control. These systems facilitate automatic depth and slope controls, increasing the efficiency and quality of the milling process.

Automation Features

Automation in Wirtgen machines includes load-dependent water systems for dust control and adjustable drum speed, optimizing fuel efficiency and operational capability under various working conditions.
