main features1. Specially designed for measuring and controlling powdered materials.
2. The feeding spiral has a unique stable flow structure, and the powder evenly sinks across the entire feeding port section, making it less prone to arching and material flushing.
3. The cycloidal pinwheel reduction motor ensures long-term stable operation.
4. The steady flow spiral adopts a variable pitch structure and an outlet overflow method, effectively solving the problem of material flushing (double tube steady flow is used for production>60T/H).
5. The measuring spiral scale adopts a direct weighing structure with three high-precision sensors (tension), which successfully solves the error caused by lever weighing and greatly improves the measuring accuracy.
6. Adopting a digital acquisition module with an effective resolution of up to 1 million; Collection rate of 50 times per second; Annual drift less than 50PPM; The temperature drift is less than 50PPM.
7. Sealed structure to reduce dust emissions.TECHNICAL INDEXMeasurement accuracy: ≤ ±1%
2. Control accuracy: ≤ ±2%
3. Speed range: 10:1
4. Working mode: continuousWorking principleThe material weight signal from the measuring screw is transmitted to the 3U403 (one machine, one DCS interface) or 3U600 (one machine, sixteen channels) measurement and control system (both 3U403 and 3U600 have microprocessors as the core). By continuously comparing the set value with the actual weight of the material conveyed by the spiral, the speed of the steady flow spiral operation is constantly adjusted. Therefore, the material flow rate can always remain stable at the set value.
