In the production of reduced pellets such as reduced iron pellets by the grate-kiln system for firing, a distributor and a belt conveyor provided with a weighing machine are arranged between a sieving machine that sieves produced green pellets to predetermined grain sizes and a travelling grate of a pretreatment furnace. The weight of green pellets fed from said sieving machine through said distributor onto said belt conveyor is continuously measured on said belt conveyor by means of said weighing machine, and a signal indicative of the measured value is fed back to said distributor. Said distributor operates in response to said signal and regulates the supply of green pellets so that the supply of green pellets to said belt conveyor, hence the supply of green pellets to said grate is kept constant. Said distributor is of such a construction as will not crush green pellets.
