The single silo single weigh dynamic automatic batching system is a quantitative feeding setup in which each storage bin corresponds to an independent weighing unit. Classified as continuous dynamic batching equipment, it differs from traditional batching machines where multiple bins share a single scale.
Each raw material has its own dedicated storage bin and independent belt-weighing mechanism, ensuring no cross-interference between materials; this makes the system ideal for batching operations involving various powdered and granular raw materials used in organic and compound fertilizers.
Drawing on our hands-on experience commissioning hundreds of fertilizer production lines, the entire batching process consists of six straightforward steps:
System Self-Check: Upon starting the control cabinet, all weighing scales automatically zero and calibrate, while the system checks the status of conveyor belts, motors, and sensors;
Recipe Selection: The operator selects the specific raw material ratio parameters for the fertilizer to be produced via the touchscreen interface;
Material Discharge: Anti-bridging devices activate, allowing raw materials—such as fermented manure, straw powder, and bentonite—to drop onto the weighing conveyor belt;
Dynamic Weighing and Feeding: Sensors transmit real-time material flow data, and the PLC adjusts the belt speed to ensure precise, metered feeding;
Converged Conveying: Once metered, the various raw materials drop onto a lower collection conveyor belt for transport to the next stage; if further mixing is required, the materials can be fed directly into a twin-shaft mixer (details available on the mixer product page);
Batch Recording and Cyclic Operation: The system automatically logs the consumption of each raw material for the batch and then repeats the feeding cycle.
Single silo single weigh dynamic automatic batching systems are suitable for handling powdered, granular, and liquid materials across various industries, including:
Fertilizer Industry: Batching for the production of BB fertilizers, organic fertilizers, compound fertilizers, and blended fertilizers.
Chemical Industry: Ingredient proportioning for fine chemicals, coatings, PVC plastics, and other materials.
Feed Industry: Precision batching for livestock, poultry, and aquaculture feeds.
Construction Materials Industry: Proportioning of materials such as dry-mixed mortar, concrete, and cement.
Food and Pharmaceuticals: Precision weighing of food additives and pharmaceutical raw materials.
Other Industries: Powder and granule handling applications in sectors such as glass, ceramics, metallurgy, and rubber.
From standalone weighing stations to large-scale batching production lines, the system offers customized automatic batching solutions tailored to user requirements.
Within the complete fertilizer production line, the single silo single weigh dynamic automatic batching system serves as the core intermediate batching stage; the compatible upstream and downstream equipment is listed below:
Upstream raw material pre-treatment: Semi-wet material crusher (crushes caked or fermented manure before feeding it into the batching bin);
Downstream mixing stage:Horizontal ribbon mixer, twin-shaft paddle mixer;
Granulation stage: Disc granulator, rotary drum granulator;
Post-processing equipment: Dryer, cooler, screening machine, fertilizer packaging machine.
