TDG series screw scales are designed for the precise metering of powder materials during screw conveying. Key features include a sealed structure to prevent powder leakage, them widely used in environments with strict requirements such as cement products, cement raw materials, lime powder, fly ash, and grain processing. The control system can utilize intelligent meters or industrial control systems, allowing for standalone operation, group operation, or integration into batching control systems.

The TDG series screw scales are a patented mechatronic product that integrates powder locking conveying, metering, quantitative feeding, and control. They are widely applicable to continuous powder metering and batching control in various production processes. Incorporating multiple advanced technologies, they offer reliable and high control accuracy, and are extensively used in industries such as power, metallurgy, coal, chemical, port, building materials, ceramics, and food.

I. Working Principle

When the material is conveyed by the variable-speed screw to the feeding inlet of the metering screw, the weighing device installed below the metering screw detects the material weight and generates a signal proportional to the weighing load, which is sent to the dynamic weighing meter. After processing by the dynamic weighing meter, the instantaneous flow rate and cumulative weight value are calculated
