Multiple Silos Single Weigh Static Automatic Batching System

A multiple silos single weigh static automatic batching system is, simply put, an arrangement where multiple raw material bins share a single weighing unit to perform batching operations; materials from all bins are fed sequentially into a common weigh hopper for measurement.

This system is primarily designed for the mixing, batching, and feeding of 3 to 8 types of materials. Common applications include compound fertilizer production, organic fertilizer processing, chemical raw material proportioning, and construction material batching. The system utilizes a computerized scale or PLC for automatic control, employing pneumatic gates to regulate the metered discharge of materials from each bin, after which the weighed materials are collectively conveyed out via a belt conveyor.

In terms of layout, the bins are arranged in a straight line or a circular configuration, with the weigh hopper positioned beneath or beside them. The overall structure is compact and has a relatively small footprint, making it highly suitable for production lines with limited factory space.

How does an automatic multiple silos single weigh static automatic batching system operate?

The operational logic of a multiple silos single weigh static automatic batching system is straightforward, centering on the principle of "sequential feeding and unified weighing."

The workflow is generally as follows:

Recipe Setup: Operators input the production recipe via a touchscreen or host computer, specifying the proportions and target total quantity for each material.

Sequential Feeding: Upon system startup, the pneumatic valves or conveying equipment for the corresponding bins are activated one by one according to a preset sequence, allowing materials to enter the weigh hopper.

Real-time Weighing: Load cells continuously monitor the weight of the material inside the weigh hopper, feeding data back to the control system in real time.

Precise Cut-off: When the accumulated weight of a specific material reaches the preset value, the system shuts off the feed mechanism for that bin and switches to the next material.

Unified Conveying: Once all materials have been weighed sequentially, the weigh hopper discharges its contents, and the materials are transported via a belt conveyor or screw conveyor to a mixer or the next processing stage.

Cyclic Operation: After discharge is complete, the system initiates the next batching cycle.

For which industries is the multiple silos single weigh static automatic batching system suitable?

The multiple silos single weigh static automatic batching system has a wide range of applications:

Fertilizer industry: Precise proportioning of various raw materials—such as nitrogen, phosphorus, potassium, and organic matter—for the production of compound fertilizers, organic fertilizers, and BB (bulk blend) fertilizers.

Chemical industry: Mixing and batching of various chemical raw materials (e.g., titanium dioxide, calcium carbonate, additives).

Construction materials industry: Batching of materials such as cement, dry-mixed mortar, and concrete admixtures.

Metallurgy and refractory materials: Precise metering of materials such as ores, carbon products, and magnesite.

Food and feed: Precise weighing of additives, seasonings, and feed formulations.

How do you select the right multiple silos single weigh static automatic batching system?

Key factors to consider include:

Bin Configuration:Determine the number of bins based on the types of materials to be batched; a standard 3–8 bin setup covers most applications. If there are plans for future capacity expansion or the addition of new raw material types, it is advisable to reserve 1–2 spare bin slots.

Production Capacity:Select a model with an appropriate capacity range based on production cycle requirements to avoid either “over-specifying” (using oversized equipment for small-scale tasks) or facing insufficient output. You must calculate the balance between the batching time per cycle and the total required production capacity.

Material Characteristics:Different material forms—such as powders, granules, or flakes—impose varying requirements on feeding mechanisms; consult the manufacturer to confirm compatibility. For instance, materials with poor flowability require forced-feeding mechanisms, while dust-prone materials necessitate enhanced sealing and dust collection designs.

Control System:Prioritize intelligent control systems that support recipe storage, data export, and remote monitoring to facilitate future digital upgrades.

Manufacturer Capabilities:Evaluate the manufacturer's ability to provide customization, installation and commissioning services, and after-sales support. It is recommended to conduct on-site visits to existing customer facilities to observe the equipment's performance under actual operating conditions.
