    The material from the storage silo is extracted, and the same is fed to the weighing hopper by using air slides and bucket elevators. The material flow to the weighing hopper is controlled with a variable speed rotary feeder. If the set quantity of material is filled in the hopper, the rotary feeder stops feeding. The balance material is
