JEL Concrete Plants manufactures material handling systems and concrete batch plants for ready mix, precast and concrete paving companies. We also manufacture parts for concrete plants, including feed systems, hoppers, bins, conveyors, radial stackers, turnheads, cement batchers, aggregate batchers and more.

One of the major causes of inconsistency in batching concrete is the varying moisture content of the sand and aggregates from one batch to another. Good storage of the sand and aggregates can help, but even for materials stored in covered silos the moisture will be constantly changing due the inevitable effects of drainage.

The concrete workability is the property of freshly mixed concrete which determines homogeneity, placed, combined, consolidated, and finished' as specified by ACI Standard 116R-90 or ACI 1990b.The w/c ratio, amount and type of aggregate and cement, admixtures, and weather conditions are the main factors that affect the workability of concrete.

Equipped with a powerful engine and 4 wheels steering, the self loading concrete mixer is just like a small truck and the operator can drive it to where it needs to go. It is very convenient for loading material, such as cement, aggregate, stone. All working from feeding material to discharging concrete can be done by one operator. Features: 1.
