Half-wet materials generally have a moisture content of 50%–70%, and their high viscosity makes them prone to clogging, bridging, and blockage. Discharge control focuses on preventing clogging, ensuring stable material flow, and protecting downstream equipment.
Control the discharge opening and discharge speed. Sudden, large-scale opening of the gate is strictly prohibited. Concentrated discharge of wet material can easily overload and stall the downstream conveyor belt and elevator. Discharge at a uniform speed according to the feed load of the half-wet material crusher(compost crusher) to ensure continuous and uniform material intake, avoiding intermittent discharge that could lead to unstable subsequent batching. If the discharge volume fluctuates, fine-tune the gate opening to maintain a consistent material layer thickness.
Prevent bridging, clumping, and blockage within the bin. Before discharge, check the bin walls for any material adhering to them. Do not forcibly open the gate if adhesive material has accumulated and formed an arch. Use a vibration device to break up the arch first. Do not allow personnel to enter the bin for cleaning to prevent material collapse and injury. Remove large clumps of material in advance to avoid clogging the discharge port and chute. For prolonged shutdowns, promptly empty any remaining material from the silo to prevent it from drying and caking.
Monitor material moisture content. In rainy weather, when raw materials are damp and sticky, reduce the discharge rate to minimize material buildup on the silo walls. If the moisture content is low and the material is loose, slightly increase the discharge rate. If the discharged material contains large, uncrushed clumps of impurities, stop the discharge and return it to the crusher for further crushing to prevent large pieces from damaging downstream equipment.
Inspect the discharge port and sealing areas, paying attention to leaks and dust spills from the chute, and repair any damage promptly. Prevent foreign objects from falling into bearings and the discharge point. Immediately shut down the discharge gate if any downstream batching or conveying equipment malfunctions to prevent backflow and blockage of the discharge silo. Regularly stop production to clean the silo, removing any adhering layers from the walls to reduce blockages and ensure stable continuous operation of the entire bio-organic fertilizer produciton line.
