[0002] In the screening and processing of iron ore powder, the screening machine is one of the core pieces of equipment, used to classify iron ore powder of different particle sizes.
[0003] After screening, the material is usually discharged through the feed inlet. However, in actual production, the feed inlet is prone to blockage due to the stickiness, moisture content, or interparticle interactions of the iron ore powder. Blockage not only reduces production efficiency but can also cause equipment overload, downtime for maintenance, and other problems, seriously affecting the continuity and economy of the production line.
[0004] Therefore, we propose an auxiliary device for preventing clogging during iron ore powder screening. Utility Model Content (a) Technical problems to be solved
