The single silo single weigh dynamic automatic batching system is an automated unit utilizing an independent "one bin, one scale" configuration; it is capable of automatically weighing, dispensing, and mixing various raw materials according to preset formulas. Unlike traditional methods where multiple bins share a single scale, this system equips each raw material bin with an independent weighing module. As the feeding and weighing processes for each material operate independently without interference, cross-contamination and delays caused by waiting for the scale are eliminated at the source.
This system is highly compatible with equipment for producing BB fertilizers, organic fertilizers, compound fertilizers, and blended fertilizers, serving as a core component of complete fertilizer production lines. Beyond the fertilizer industry, it is also well-suited for handling powdered and granular materials in sectors such as chemicals, food processing, pharmaceuticals, and building materials.
The core operational logic of the single silo single weigh dynamic automatic batching system can be summarized as "independent weighing, sequential batching, and unified mixing."
During operation, material level sensors in the storage system monitor inventory levels in real-time, automatically triggering replenishment commands when levels fall below set values. Once the batching process begins, feeding devices (such as screw conveyors or vibrating feeders) transport materials from the bins to their respective weighing systems. High-precision load cells attached to each bin perform independent dynamic weighing; the system’s dynamic weighing algorithms capture weight changes in real-time as material flows. Combined with variable-frequency drive (VFD) feeding technology, the system executes a staged feeding process—switching between fast, medium, and slow speeds—to effectively mitigate the impact of material impact forces on weighing accuracy.
After weighing is complete, the materials are transported to a mixer for uniform blending. The control core of the entire process consists of a PLC (Programmable Logic Controller) and an HMI (Human-Machine Interface): operators use the HMI to configure recipe parameters and monitor production, while the PLC precisely controls the timing and execution of material transport, weighing, and mixing based on these commands.
A complete single silo single weigh dynamic automatic batching system typically consists of the following five major subsystems:
This includes multiple independent raw material bins, each equipped with level sensors to monitor material inventory in real time. Bin designs are flexibly configured based on material characteristics: screw feeders are used for free-flowing granular materials, while vibrating feeders with agitation functions are employed for powders prone to caking.
Each raw material bin is paired with an independent weighing module comprising high-precision load cells and a weigh hopper. The system achieves Class I measurement accuracy, maintaining dosing precision within ±0.2% for materials in various forms, such as granules and powders.
Centered on a PLC and featuring an HMI (Human-Machine Interface), this system manages recipes, monitors processes, and records data. It can store parameters for hundreds of recipes, allowing for rapid retrieval and modification.
This system uniformly blends the various weighed raw materials to ensure consistent product quality.
Comprising components such as conveyor belts and pipelines, this system transports the mixed material to the next processing stage or packaging equipment.
The fertilizer production industry represents the primary application sector for single silo single weigh systems, covering production lines for organic fertilizers, compound fertilizers, blended fertilizers, and BB fertilizers. Organic fertilizer production utilizes a wide range of raw materials—from agricultural waste like livestock manure and crop stalks to industrial by-products such as humic acid and amino acids. Given the significant physical differences among these materials, the single-bin, single-scale system—with its flexible feeding configurations and high-precision weighing capabilities—has become a vital tool for organic fertilizer manufacturers seeking to enhance their core competitiveness.
Beyond this, the system is used in the chemical industry for the precise batching of raw materials in coatings, paint formulations, and plastic masterbatch mixing; in the food industry for the precise dosing of additives and seasonings; and in the pharmaceutical industry for weighing pharmaceutical ingredients that demand extremely high precision. As intelligent, unmanned factories become a key direction for industrial transformation and upgrading, the scope of application for single-bin, single-scale automatic batching systems continues to expand.
