In an organic fertilizer production line, the conveying segment is the "link" connecting the crushing, fermentation, granulation, and packaging processes. Its efficiency directly impacts the production capacity and stability of the entire line. To avoid material accumulation and conveying jams, scientific planning is required from three aspects: equipment selection, layout design, and operation and maintenance.
Rational conveying equipment selection is crucial. Differentiated selections should be made based on the material characteristics of each process. Belt conveyors are ideal for crushed dry materials (such as straw powder). They offer high conveying capacities (up to 5-20 tons per hour), adjustable speeds, and a smooth, easy-to-clean belt surface, minimizing material residue. Bucket elevators are suitable for granular materials. Vertical conveying saves workshop space, and a sealed hopper prevents granules from spilling, accommodating the required height between the granulator and packaging machine. Furthermore, all conveying equipment must be constructed of corrosion-resistant materials, such as stainless steel or galvanized steel, to accommodate the acidic and alkaline properties of organic fertilizers and extend equipment life.
A scientific layout is essential. Conveyor routes should adhere to the principle of "shortest paths and fewer turns" to minimize resistance and energy consumption. Bucket elevator inlets are equipped with buffer devices to prevent particles from impacting and damaging the hopper. Belt conveyors are tilted no more than 15°; for larger angles, corrugated belts with sidewalls are used. Level sensors are installed at key points to automatically warn when material accumulation exceeds the limit, adjusting the conveyor speed to prevent overload and shutdown.
Proper operation and regular maintenance are key. Operators must strictly follow the "pre-startup inspection - ongoing monitoring - post-shutdown cleaning" process: Before starting up, check the conveyor belt tension and wear of the scraper or hopper. During operation, monitor the material conveying status in real time and make timely adjustments if any deviation or jamming is detected. After shutting down, thoroughly clean any remaining material inside the equipment, especially wet and sticky materials, using a high-pressure water jet to prevent caking and blockage. Regular maintenance includes weekly lubrication of conveyor bearings, monthly inspection of the tightness of the scraper and hopper, and timely replacement of worn parts to ensure efficient operation of the conveying chain and maintain stable production capacity of the organic fertilizer production line.
