Informatization Weigh Feeder System is a set of complete system equipment for continuous conveying, dynamic weighing and feeding control of granular and lump material on real-time. Informatization weigh feeder is a new generation intelligent product of traditional weigh feeder, which applies modern information technology to automation control system to realize the continuous weighing and control of granular material and bulk material. The control system has the characteristic of high degree informatization and can achieve production modernization and comprehensive production management through humanized operation.
● With the functions of message notification and alarm, and can bind more than one user's mobile phone numbers( such as directors and professional engineers, etc.) anywhere at any time.
● Commissioning and calibration adopts wireless hand-held equipment with friendly interface and easy operation.
● Weight feeder connected with DCS and the frequency converter through 485 bus. Using Modbus communication protocol makes the connection simple.
● For weighing and measurement, it adopts double load cell and direct gravimetric structure with the characteristics of simple structure, easy to install, easy to maintenance.
● For mechanical structure, the design is more flexible.
● The feeder has been equipped with automatic compensation cleaner to avoid the trouble of manual adjustment after the wear of the cleaner.
● Professor of the control system adopts 32 bit ARM chip, can greatly improve measurement accuracy and control precision.
● Touch-screen human-computer interface is user-friendly, so user can operate the weigh feeder without remembering lots of parameter codes so as to save the training cost.
● Application fields: All continuously operated processes e.g. mill feeding Suitable Materials: Fine, coarse and sticky materials such as limestone, gypsum, clay, clinker, iron ore, coal, coke, pellets, additives etc.

Control box of informatization weigh feeder collects belt speed signal and weighing signal by speed measurement device and load cell and calculates the instantaneous flow rate and adjust the motor rotary speed by frequency converter through 485 bus and Modbus communication protocol.
The field control box collects the belt deviation signal by limit switch and sends the operation condition of the weigh feeder to user's mobile phone or computer through GPRS message module.
User can operate and commissioning the weigh feeder through touch screen or wireless hand-held instrument and meanwhile the automatic control of the system can be realized through upper computer.
