Tips in operating concrete mixer and electric pump combination

The concrete mixer and electric pump combination is an integrated concrete machinery for combining mixing and pumping of ready mixed concrete. The mixing degree and state of concrete influences directly the building quality of a project. A mixer and pump cannot match a complete set of concrete batching plant for mixing efficiency and quality, for its configuration is very simple. However, proper running helps to bring the potential of a concrete mixer pump into full play. Here are some tips in operating it.

First, pay attention to raw material control. The raw materials for concrete are sand, aggregates, water and cement. Great importance should be attached to the aggregate size here. Generally, the sizes of the crushed stone fall on 10mm, 20mm, 30mm and 40mm. Each size accords to a capacity of the concrete mixer and pump. For example, 40m3 concrete pump can deal with 30mm aggregates, if you feed aggregates of larger sizes, the pumping pipe might be clogged. The ratio of raw materials should be 2:1:1.

Second, control the mixing time strictly. The mixing time of concrete has a significant effect on the homogeneity of the mixture. Shortage of mixing time leads to uneven strength and workability of the concrete, while extra mixing will not only affect the efficiency of the mixer, but also reduce the workability of the concrete again or cause delamination and segregation. Generally, the mixing time of the mixing drag pump has been scientifically set, and the mixing time of a tank of raw materials is about 15S. Or you can refer to the instructions to set a proper time period.

Third, when the concrete is finished mixing? The finish of mixing is marked by even mixing of materials and uniform color of concrete. This is particularly important for hard and dry concretes.
