Belt weighing batcher is intended for continuous and portion batching of granular materials in mining and smelting, chemical, building and other branches.

• conveyor with the electric drive;
• receiving hopper;
• weight measuring device;
• belt speed sensor;
• weighing processor;
• panel of the local control;
• device of the drive control
• portable board.

During the operation of the belt weighing batcher the weight measuring device continuously measures the material load, incomming from the receiving hopper on the conveyor belt. Simultaneously the speed of belt moving is measured on the signal from the speed sensor. Under this data the weighing processor calculates the actual capacity of the batcher, the value of the mismatch of capacity with the set one and formes the corresponding signal on the adjuster output of the frequency converter.
The converter changes the rotation speed of the drive, keeping the set capacity of the batcher. The weighing processor evaluates the value of the portion and the total amount of the material which has passed through the feeder.
