Understanding Used Cement Mixers
Before diving into the specifics of buying a used cement mixer, it’s essential to understand what these machines are, their types, and how they function. Cement mixers, also known as concrete mixers, are devices used to combine cement, aggregate (such as sand or gravel), and water to form concrete. The mixing process must be thorough to produce a uniform and workable mixture, and the right mixer can significantly improve construction efficiency.
Types of Cement Mixers
Cement mixers come in various configurations, each suited to different scales of work and operational needs. The main types include:
1. Drum (Tilting or Non-Tilting) Mixers
- Tilting Drum Mixers: These mixers feature a drum that tilts to discharge the mixed concrete. They are generally portable and ideal for small to medium projects.
- Non-Tilting (Horizontal) Drum Mixers: The drum rotates without tilting, and concrete is discharged via a chute or on the ground. They are often used in larger projects.
2. Stationary Mixers
- Fixed in place, these mixers are suitable for large-scale industrial or commercial applications where continuous mixing is required.
3. Continuous Mixers
- Designed for high-volume, ongoing production, these mixers combine ingredients continuously as the materials pass through.
4. Portable Mixers
- Smaller, often hand-fed or walk-behind models, suitable for small projects, repairs, or on-site mixing in hard-to-reach locations.
Key Components of a Cement Mixer
Understanding the main parts of a cement mixer helps in assessing its condition and suitability:
- Drum: The rotating container where mixing occurs.
- Motor: Powers the rotation of the drum.
- Frame/Base: Supports the entire structure and provides mobility.
- Discharge Chute: Directs mixed concrete out of the drum.
- Gearbox: Transfers power from the motor to the drum.
- Controls: Switches and levers to operate and control mixing functions.

- Ensure the engine is in good condition, with no leaks or excessive smoke.
Capacity and Size
- Match the mixer’s capacity (measured in cubic feet or cubic meters) with your project needs.
- Larger capacity mixers are suitable for bigger projects but may be less portable.
Brand and Model
- Reputable brands like Belle, Crown, or Multiquip are known for durability.
- Research specific models for common issues or advantages.
Cost and Value
- Compare prices across sellers and consider the cost of potential repairs or refurbishments.
