The invention discloses a metal recycling and feeding method. When a feeding device does not feed a material to a discharging device, a material guiding plate enables an upper plate surface of the material guiding plate to squeeze a lower port of a material guiding drum under the action of the gravity of a balancing weight, so that the discharging device is in a closed state; when the feeding device feeds a material to the discharging device, a metal recycling material enters the material guiding drum through a feeding hopper and falls onto the material guiding plate; when the weight of the fed metal recycling material is greater than that of the balancing weight, the material guiding plate rotates around a hinged portion and tilts downwards, so as to guide the metal recycling material onthe material guiding plate onto a furnace bottom of a melting chamber; when the metal recycling material on the material guiding plate is all poured into a furnace, the material guiding plate blocks the lower port of the material guiding drum again under the action of the gravity of the balancing weight.
