Concrete Batching Plant Technical Manual

- Feb 21, 2019 -

一、HZS90Q concrete batching plant, equipped with JS1500 twin shafts mixer and belt type aggregates charging system, has rated output 90m3/h compacted concrete. It can mix various kinds of concrete and suitable for medium size construction sites, power stations, irrigation, highways, airfields, bridges, and medium size factories producing concrete prefabricated parts.

The plant is composed of batching system, weighing system, mixing system, electrical control system, pneumatic control system and etc. Three aggregates, one powders, one liquid additive and water can be automatically scaled and mixed by the plant. Aggregates were loaded to aggregate bin by front loader. Powder is conveyed from silo into weighing scale by screw conveyor .Water and liquid additive are pumped to the scales. All the weighing systems are electronic scales.

The plant is fully automatic controlled by computer with production management and data printing software.
