Self Loading Mixer Truck

How Does LUTON Self Loading Mixer Truck Work

When self loading mixer truck is used to produce concrete materials on site, only one operator and one auxiliary worker can efficiently complete the entire operation process, which is simple and convenient, saving time and manpower. Thanks to our engineers have designed such a highly integrated automatic mixing equipment and stable process control.

Its work process is completed in one go, and it is the result of the collaboration of multiple functional systems. Next, let’s take the drum type concrete mixer truck as an example to see how they work!

Loading Materials

The first step is certainly loading materials.

Without too many workers involved, the operator of the self loading mixer truck starts the diesel engine and the entire operating system in the operation cab, and then pulls the gear lever. Under the powerful drive of the hydraulic pump, the mechanical arms at the front of the truck drives the bucket loader to load cement,sand and other raw materials.

Measuring Materials

The raw materials are lifted by arms up to a certain height, the electronic weighing system switch is triggered and the mixer truck enter into the material weighing process, the second step of all working process.

Actually, there are two individual measuring system: aggregate weighing system and water measuring system. The two systems usually working separately and simultaneously.

To aggregate weighing, the self mixing concrete truck is equipped with a set of electrical weighing device and display instrument, which enable operators get the result directly and immediately. Accurate weighing results are the basis of good ingredient quality.

At the same time, water is measured by an electromagnetic flow meter and the water feed can be also read on the display screen in the operation cab.
Operators can easily activate the water pump by the driver’s seat to support water.

During measurement, the system sends an instruction, and the water supply pump starts.

At this time, the relay starts timing. When up to the preset value, the system sends an instruction to operator to stop the water supply pump, and the measurement ends.

When the loader reaches the highest point, the hydraulic control system obtains the signal of opening the discharge door at the bottom of the loader, and the weighed aggregate is unloaded into the mixer.

By this time, the third step begins.

Mixing Materials

Material mixing is the third step in the entire concrete production process, and it is also the core part. The weighed material is unloaded into the slowly rotating mixing drum by the loader, and at the same time, water is also added into the mixing drum. The mixing blades are designed and installed on the inner wall of the mixing drum to fully tumble and stir the Materials. Materials are constantly sinking with gravity until homogeneous concrete mix is
obtained. This process usually lasts about 2-5 minutes.

Unloading Concrete

Now it comes to the forth step, unloading process. In this stage, operator controls the mixing drum to rotate reversely through operating lever. In this way, the mixing blades will send the concrete mortar out of the drum.

With the help of the slewing support device on the chassis, the concrete mixing drum can be rotated horizontally by 270°. Sometimes, a removable chute is necessary, which is installed at the outlet of the mixing drum and extends the unloading distance.

And the chute can be rotated 90° mostly, which expands the paving area.

All of above mentioned realize the full area paving of concrete.

Cleaning Mixing Truck

At last, cleaning procession is also a working step that cannot be ignored.

The water tank is pressurized through the air reservoir of the braking system. And the pressurized water flows can be used to clean mixing tank system, loading port, unloading system, etc.

Keeping clean is the most basic daily maintenance for mixer trucks.
