What to Do with the Hopper Whilst Pumping Concrete?

The concrete trailer pump hopper, also known as aggregate hopper, is an important part of the machine. Equipped with mixing blades, the hopper not only carries the liquid concrete but also improves the cohesion of the cement. More importantly, it keeps rotating to prevent the concrete from segregation or solidification.

Well, many operators have no clue what to do with the hopper when the pumping system works and sucks wet concrete out of the hopper.

First, there should be a screen mesh on the hopper to prevent large stones and rocks falls into it. Also, arrange the personnel to inspect the aggregate discharge, avoiding the clog and blockage caused by large rocks and other objects.

Second, during the pumping, the concrete horizontal line should be always lower than the mixing shaft, otherwise, the pipeline will vibrate caused by air entering pipelines.

Third, after the pumping work is done, clean the hopper and pipelines thoroughly. If the remaining concrete in the material cylinder is not removed timely, it is more likely to stick to the cylinders and solidifies.

When the piston pushes again, it will withstand the pressure of the solidified cement, which will damage the position. The damage is not different from normal wear of piston seal, and it is unable to compensate under the pressure. Therefore, in this case, cement leakage, weak suction, and pumping or blockage will happen.
