Abstract: A bag filling apparatus includes a hopper for receiving raw material. The hopper feeds the material through an opening to a conveyor belt for transporting the material to a bagging head. The bagging head includes a gate having two positions for selectively diverting the material to one of a first and a second outlet ports. Underneath the bagging head is a receiving scale having a first pan and a second pan, each adapted to hold a bag for receiving the material, and a movable counterweight. The scale is constructed to move between two positions: a first position wherein the first pan is adjacent the first outlet port and the counterweight is adjacent the second pan and a second position wherein the second pan is adjacent the second outlet port and the counterweight is adjacent the first pan. The movement of receiving scale between the two positions occurs automatically when the sandbag reaches a preselected weight.
