In the construction and concrete transportation industry, the concrete mixer truck is an essential piece of equipment. Over time, the mixing drum—or tank—undergoes severe wear and tear due to constant rotation, abrasive materials, and harsh operating environments. Instead of purchasing a brand-new truck, many contractors and construction companies are choosing a more cost-effective solution: replacing the mixer drum.
In this article, we’ll explore when and why to replace a mixer drum, the replacement process, important considerations, and how to choose a reliable supplier for your replacement drum.
The mixer drum is the core of any concrete mixer truck. It performs the critical function of mixing and transporting concrete to job sites. After years of operation, several issues can arise:
Severe wear on the inner lining
Reduced mixing efficiency
Cracks or corrosion due to cement buildup
Deformation from overloading or improper operation
These issues can lead to lower quality of concrete, longer mixing times, and even safety risks. Replacing the drum helps restore the truck’s full functionality and increases its service life without the cost of replacing the entire vehicle.
Some clear signs that it’s time to replace the mixing drum include:
Visible cracks or dents in the drum
Excessive leakage during mixing or unloading
Noisy or unbalanced rotation
Significantly reduced drum thickness
Mixing blades inside the drum are worn or broken
A professional inspection can confirm the condition of the drum and recommend a suitable replacement time.
Replacing a concrete mixer drum requires technical expertise and the right equipment. Here’s a general overview of the process:
Inspection and Measurement
The existing drum is measured to ensure compatibility with the replacement drum. Key dimensions include drum length, diameter, mouth opening, and mounting points.
Removal of the Old Drum
The old drum is removed carefully using a crane or lifting equipment. All hydraulic connections, rotation supports, and mounting bolts are detached.
Installation of the New Drum
The new drum is positioned and mounted. Technicians align it with the chassis, fix it securely, and connect the hydraulic system.
Testing and Quality Check
The drum is tested for proper rotation, balance, and discharge. Any issues are addressed before putting the truck back into service.
Before proceeding with drum replacement, consider the following:
Compatibility: Ensure the new drum matches your truck’s model, chassis type, and power system (diesel, electric, etc.)
Material and Thickness: High-quality steel, such as Q345 or NM400, ensures durability and wear resistance.
Mixing Blade Design: The internal blade structure should ensure fast, uniform mixing and easy discharge.
Supplier Reputation: Choose a manufacturer or supplier with experience, proper certification, and support services.
Cost and Delivery Time: Compare prices and lead times. Some manufacturers offer ready-stock or quick delivery options.
