Due to its special characteristics, materials tend to get entangled as the spiral shaft rotates, and the bearings mounted in the middle can also become clogged with materials; therefore, clogging is the most common fault that occurs. Once the conveyor gets clogged, it increases power consumption; in severe cases, it can even damage the motor. How can blockages be resolved? The editors at Shanghai Yuyin have compiled several tips for you. 1. Strictly follow the operating procedures: start without load and stop with no load; ensure a continuous and uniform feed. 　　2. The various technical parameters should be selected appropriately; for example, the low-speed rotation speed should not be too high. 　　3. Enlarge the discharge outlet or extend the end of the material chute to address issues such as poor discharge or delayed discharge. At the same time, a short section of blades with a reverse rotation direction can also be installed at the end of the discharge trough to prevent blockage at that end. 　　4. Minimize the lateral dimension of the intermediate suspension bearing as much as possible, in order to reduce the risk of blockages when materials pass through this bearing. 　　5. Thoroughly clean the materials entering the conveyor to prevent overly mixed or fibrous impurities from entering and causing blockages. 　　6. Install silo level sensors and blockage detectors to achieve automatic control and alarm functions. 　　7. A anti-clogging valve is provided on the discharge end cover plate. When a blockage occurs, the accumulation of material pushes open the anti-blockage door, which in turn cuts off the power supply via a limit switch.
