Description

Technical Field

[0001] The utility model relates to a modified material production process, in particular to a feeding system equipped with a movable screen. Background Art

[0002] In the mixing stage of industrial production, manual feeding is required. During the feeding process, the raw material bag must be cut manually and then the material is directly poured into the hopper. However, during the cutting process, the raw material bag residue, the raw material bag binding rope, and other impurities will be put into the hopper together with the material, and during the feeding process, the material will often clump. When large pieces of material and impurities enter the processing system from the hopper, they will cause the loss-in-weight scale and extruder to malfunction, hindering the reaction.
