Screw scale Shandong Lingrui factory direct sales measurement is accurate and after-sales service is perfect

Screw scale
Product introduction
  Spiral scale is a special measuring equipment for continuous weighing, batch feeding and batching of various powdery and bulk materials
It is especially applicable to the measurement of powder materials with strong fluidity, such as fly ash, pulverized coal, etc
The screw scale is widely used in building materials, cement, chemical industry, coal, mining, ceramics, glass, metallurgy, grain, chemical fertilizer, feed, port, electric power, coking, environmental protection, transportation and other industries
working principle
  The weight signal of the material from the metering screw and the speed signal of the screw operation are transmitted to the controller together to automatically calculate the instantaneous flow of the material and the cumulative output of the material
By continuously comparing the set flow with the actual material flow, the speed of the metering screw is constantly adjusted, so that the material flow can always be stable at the set flow
At the same time, in order to ensure precise / accurate feeding, the advanced feedforward regulating system 3u-s control system is adopted
The 3u-s control system continuously adjusts the speed of the powder balance locking device according to the set feeding volume measurement, and achieves very precise / accurate, stable and continuous feeding
Screw scale with double control function &mdash& mdash; Control the feeding stability of the powder balance lock and the metering screw speed to improve the metering accuracy
Performance characteristics
1
The advanced feedforward regulation system 3u-s control system is adopted

2
The patented powder balance locking device is adopted to ensure stable feeding

3
The double control function is adopted, and the powder balance lock and metering screw are adjusted at the same time to improve the metering accuracy

4
Large feed inlet, variable diameter, variable distance and overflow outlet are adopted to ensure that the materials sink evenly, are stable and controlled, and do not collapse the warehouse, shed materials and channeling materials

5
It adopts high-precision digital weighing module and digital transmission technology, with simple circuit, no adjustment parts, high resolution, no signal attenuation and strong anti-interference

6
The controller adopts touch display technology, Chinese and English graphical display, wizard operation mode, simple operation and no memory

7
It can be connected to 485 communication, can communication, DCS, PLC and other interfaces

8
GPRS wireless data transmission function is adopted, including short message report, remote diagnosis, scale calibration and other functions
