The multiple silos single weigh static automatic batching system is equipment designed for the precise metering of various materials; its core feature can be summarized in a single phrase: multiple independent storage bins sharing a single weighing unit.
The system comprises four main components: the storage bin system, the metering system, the conveying system, and the control system. Typically featuring between three and eight bins—each dedicated to a specific raw material—the system effectively prevents cross-contamination during the batching process. All bins share a high-precision load cell and a weigh hopper, with an intelligent control system managing the sequential, precise weighing of each material.
This “multiple bins, single scale” design ensures batching accuracy while significantly reducing equipment costs, making it a mainstream solution for applications such as small-to-medium-sized production lines and compound fertilizer processing.
The workflow of the multiple silos single weigh static automatic batching system is not complicated, but each link relies on precise control logic.
Step one: recipe setting. The operator presets the proportion of each material and the total amount of each batch in the control system.
Step 2: Sequential feeding. After the system is started, the batching process of each warehouse will be started automatically starting from warehouse No. 1. The control system opens the pneumatic valve or conveying equipment corresponding to the silo, and the materials begin to be discharged into the weighing and batching hopper.
Step 3: Real-time weighing and precise stopping. The load sensor continuously monitors the real-time weight in the batching hopper. When the material weight reaches the preset value, the corresponding silo immediately stops supplying materials. The core difficulty in batching accuracy lies in “stopping accurately” - there is inertia between the material falling from the feeding port and completely stopping. When the scale reaches the target value, there is still a section of material in the air that has not fallen. An excellent system will compensate for this “gap” through algorithms, which is also the key to the difference in accuracy of equipment from different manufacturers.
Step 4: Mixing and output. After all the materials are batched in sequence, they are mixed in the mixing bin, and finally sent out automatically by the belt conveyor to enter the next process or packaging link. The system then enters the next batching cycle.
Fertilizer production. These systems serve as core auxiliary equipment for production lines manufacturing organic fertilizers, compound fertilizers, and blended fertilizers. They enable precise proportioning of various raw materials—such as nitrogen, phosphorus, potassium, and organic matter—and are widely used in the production of bio-organic fertilizers (e.g., from chicken manure) and the processing of compound fertilizers.
Chemical industry. Used for the precise proportioning and mixing of various chemical raw materials, pigments, additives, and other fine chemical ingredients.
