materials weighing system

Material weighing system affecting the quality precast concrete plant and concrete production cost of key components, divided into aggregate weighing, weighing powder and liquid weighing three parts. Under normal circumstances, less than 20 cubic meters per hour, concrete mix plant 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 put into the water, said liquid additive pre-mixed bucket. In more than 50 cubic meters per hour, mixing station, the use of the said materials weighing independent way, all have adopted electronic weighing scales and computer control. Aggregate weighing accuracy ≤ 2%, cement, powder, water and admixtures are up weighing accuracy ≤ 1%.
