Concrete Mixer Trucks Explained: Definition, Types, and How They Work

Look! Big Trucks Mix Concrete!

Have you ever seen a big truck with a spinning drum on the road? That is a camión mezclador de concreto. Some people call it a camión mezclador de cemento, a mezclador de transporte, or a concrete agitator truck. These big trucks do an important job. They help build roads, houses, bridges, and more.

What is a Concrete Mixer Truck?

A camión mezclador de concreto is a construction vehicle with a giant drum that spins. Inside the drum, it mixes cement, water, and aggregates like sand and gravel. This makes concreto. The truck brings the wet concrete to the place where builders need it.

Why do we need concrete mixer trucks?

  • Concrete gets hard fast. It must stay soft until builders use it.
  • If you drive too long, the concrete will dry and be bad.
  • We need the mixer truck to keep the concrete soft and ready for use.

Concrete mixer trucks are heroes of the construction industry. Without them, we would not have smooth roads, tall buildings, or cool bridges.

A long time ago, people mixed concrete by hand. Now, machine trucks like ours make it quick and easy. At GRUPO CLW, we make these big trucks strong and just right for your job.

How Concrete Mixer Trucks Work

  • Loading: The truck goes to a concrete batch plant. Cement, water, and sand go into the drum, through the loading hopper.
  • Mixing: The drum spins with spiral blades called fins. They mix everything together.
  • Transporting: While driving, the drum keeps spinning slowly. This is agitation. It keeps the concrete mixed and soft.
  • Discharging: At the job site, the drum spins the other way. Concrete comes out, down the discharge chute.

    The Mixer Drum

    The drum has strong spiral blades inside. They mix by spinning one way and discharge by spinning the other. High-strength steel keeps it tough. Our trucks have drum rotation speed controls so you can make the drum spin fast or slow.

    Sistema hidráulico

    Ever wonder how a big drum spins with so much concrete? It is the hydraulic pump y hydraulic motor. They use high pressure (about 250-450 bar!) to turn the drum. Our trucks at CLW GROUP use top hydraulic systems. This keeps your work safe and easy.

    The Mixing Process

    The drum turns fast to mix (about 10-18 rotations per minute), then slow (2-6 rpm) as the truck drives. The internal blades break up lumps and mix all the pieces. The chasis y suspension make a smooth ride so the mix stays just right.

    The Discharging Process

    When you reach the site, spin the drum the other way. The concreto comes down the swiveling chute. If you need to pour in a hard spot, you can add chute pieces! The discharge rate is about one whole cubic meter every minute. Just think: that's enough for a giant backyard patio!

    Types of Concrete Mixer Trucks

    Not all mixer trucks are the same. At GRUPO CLW, we build many kinds. Here are the main types:

    1. Transit Mixers (Ready-Mix Concrete Trucks)

    • Concrete mixes inside the drum, on the road or at the site.
    • Most common type on big jobs: houses, road work, bridges.
    • Load from a big planta de dosificación.
    • Pueden ser rear discharge o front discharge for easy pouring.
    • Excelentes para construction sites that need lots of concrete!

    2. Volumetric Concrete Mixers

    • Holds dry parts (cement, aggregates, water) in bins.
    • Mixes the concrete right at the site. No waste!
    • You get fresh, just-right concrete every time.
    • Super for small jobs, remote places, or when mix changes a lot.

    3. Self-Loading Concrete Mixers

    • Scoop up sand and cement by themselves with big buckets!
    • Make and pour concrete without a crew.
    • Mix on-site, fast and easy.
    • Like volumetric mixers, but they do the hard work for you, even in tough spots.

    Why Concrete Mixer Trucks Are Important

    • Bring concrete to far-away places.
    • Keep concrete soft, ready to use.
    • Save builders lots of time and hard work.
    • Needed for big and small jobs – houses, buildings, roads, and bridges.
