In fact, when you see various cement mixers on the road, you will find that the cans on the car are rotating constantly, with the purpose of preventing cement from hardening.

In addition to excavators, cranes, and road rollers, the most common one on construction sites is cement mixer trucks. We all know that cement is composed of various sand and gravel and is very easy to harden. So why doesn’t the cement in the cement mixer tank solidify?

In fact, when you see various cement mixers on the road, you will find that the cans on the car are rotating constantly, with the purpose of preventing cement from hardening.

During transportation, the drum will be kept at about 4-8 revolutions every minute to keep the concrete from separating and make the cement material more uniform. Of course, rotation can prolong the time for cement to solidify, but it does not mean that it will be extended indefinitely. Generally, even rotation can be extended by about 3-5 hours.

Sometimes the weather temperature and the allocation ratio of concrete will also affect the time of solidification. If the tank truck cannot clean it in time, the cement in the tank will solidify, and at this time, it can only be manually cleaned, which is very time-consuming and labor-intensive.

Some friends also found that the can of the cement truck is facing upward, so how to discharge the cement? It turns out that rotating blades and hydraulic systems are provided in the cement tank . During the feeding and transportation process, these devices in the cement tank will rotate forward, so that the concrete in the tank can be properly fed and stirred.

When you arrive at the construction site and need to discharge the cement, the rotating blades and hydraulic device will rotate in reverse to discharge the cement.

Cement mixer truck not only saves time and effort, but can mix concrete more evenly, but also consume less materials, improve construction efficiency, and reduce various environmental pollution. It is an indispensable role in construction sites.
