concrete mixing station metering system

Metering system is affecting the quality of concrete and concrete production cost of key components, mainly divided into Stabilized Soil Mixing Plant, powder weighing and A liquid weighing three parts. Under normal circumstances, less than 20 cubic meters per hour, mixing station using superposition weighing methods, namely aggregates (Sand, stone) with a scale, a scale with cement and fly ash, water and liquid admixtures were weighed, and then the liquid admixture Put into the bucket of water, said pre-mixed. In more than 50 cubic meters per hour, mixing station, the use of the said materials independently weighing Way, all have adopted electronic weighing scales and ready mix concrete plant. Aggregate weighing accuracy ≤ 2%, cement, powder, water and admixture Weighing accuracy to achieve ≤ 1%.
