This scraper mixer upstream system is independently developed by our company according to the principle of water wheel, mainly applicable to the plane structure of single-floor workshop buildings. This system can reduce the plant investment to the maximum extent and also retain the high control accuracy, stable operation, low energy consumption of the vertical screw-feeding upstream system. It is used for conveying carbon black/fillers with the means of the scraper circulation operation carrying materials to the scale for weighing. It can ensure carbon black/fillers to be conveyed in a closed state without dust leakage.

Compared with the negative pressure mixer upstream system commonly used in the single-floor workshop buildings, the scraper upstream system has very obvious advantages and is worthy of promotion and selection.
