Screw feeding scale mainly suits for fixed weight packing of powdery material. Screw feeding scale without hopper is applicable for the plant limited by the space or packing of powder material with high viscosity or with air, such as premix, ultrafine powder, flour, starch, etc. Moreover, the screw with hopper suits for packing of powder material which requires for high packaging speed, such as concentrate feed, ruminant feed and premix.
