The Working Principle and Product Features of Belt Weigh Feeder



Belt weigh feeder is a perfect equipment  for continuous weighing, feeding and dosing of bulk material and powder, and can also realize open-loop and closed loop flow control. It can be widely used in building materials, chemicals, coal, ports, ceramics, food, fertilizer, and other industries.It normally works together with belt conveyor.
Working Principle:
Electronic weighing devices are installed in the bottom of the conveyor belt,the weight of belt material effect on the weighing sensor,,and generate a electrical signal which is proportional to the material weight,and enter the system controller;at the same time, the belt running speed is measured by the speed sensor which is installed on the passive roller and taken to a system controller;according to the integral of material weight signal and material speed signal,it can calculate the instantaneous flow rate of material and the total cumulative amount of material.
Product Features:
1.Double sensor weighing;
2.Running deviation prevention device:maintain the belt efficientoperation at all times;
3.Automatic tensioning device:effectively prevent the belt from sagging skid;
4.Inside and outside the sweeper device:ensure zero residual materials;
5.Control system:a standard RS232 / 485 outlets ( standard Modbus RTU protocol).
