Cumulative weighing method used in concrete batching plant can achieve good results. This weighing system is a combined weighing machine, and it is composed of cement weighing scale and sand accumulation scale. The cement scale is set in the middle, and sand accumulation scale is set on both sides. In the level system of concrete batching plant, cement and stone have separate weighing system and separate discharging gate.Henan Daswell Machinery is a professional manufacturer of construction machine for almost 30 years in China. We are dedicated to supplying our customers with best service and products, our major products include:mobile concrete mixer,Cement Silo,If you are interested in our products, please contact us freely: sales@daswell.com Since concrete batching plants in nowadays usually divide the aggregate into two groups. That is to say, there are usually two weighing devices Mini concrete mixer equipment, namely coarse aggregate weighing device and fine aggregate weighing device. This weighing method has been widely applied, and cement is also weighed by this method. In order to avoid chemical changes, additive cannot be weighed in this way. Therefore, additive weighing usually has two devices. Water weighing adopts cumulative weighing method to weigh the clean water and recycling water together. In the production process of concrete mixing plant portable concrete batch plant SICOMA Twin-Shaft Concrete Mixers, aggregate, concrete, water and additive have their own independent weighing systems. Aggregate can be weighed according to its species and size, which is called independent weighing method. Although independent weighing method has the features of high weighing precision, its intensive hopper arrangement usually makes the weighing device of concrete batching plant much complex.
