How many compartments are suitable for the static batching machine of blended fertilizer?

The selection of the number of bins for the static batching machine of blended fertilizer should be determined comprehensively based on the production scale, material type and process accuracy. The recommended range is 2 to 8 bins. The specific analysis by Zhengzhou Hanke Machinery is as follows

I. The core basis for Selecting the number of bins in a static batching machine for blended fertilizers

Production scale

Small-scale production line (daily output 5-50 tons) : 2-4 bins can meet the basic formula requirements and are suitable for the mixing of single varieties or small amounts of materials.

Medium-sized production line (daily output 50-200 tons) : 4-6 compartments can support multi-element formulas (such as nitrogen, phosphorus, potassium + trace elements)

Large-scale production lines (with a daily output of over 200 tons) : 6-8 warehouses or more, capable of precisely controlling complex formulas (such as more than 10 types of materials)

Types and ratios of materials

Simple formula (2-3 main ingredients) : 2-3 bins are sufficient, such as the conventional blending of urea, monoammonium phosphate, and potassium fertilizer.

Complex formula (4-6 main ingredients + trace elements) : 4-6 compartments are required to avoid efficiency decline caused by frequent compartment changes.

Trace additives: A separate small warehouse (such as 0.5-1 cubic meter) should be set up to prevent cross-contamination.

Process accuracy requirements

Static batching error ≤1% : The number of bins should be ≥4 to ensure that each material is weighed independently and reduce cumulative error.

Dynamic batching error ≤2% : 2-3 bins can meet the basic requirements, but it needs to be combined with a high-speed mixer to shorten the cycle.

Ii. Typical Warehouse Number Configuration Plan

Advantages of applicable scenarios for warehouse numbers

The 2-warehouse small-scale farm and test line have low costs (starting from about 18,600 yuan) and are easy to operate

Large-scale compound fertilizer factories with 5-6 warehouses, customized production, precise formula control, and reduced warehouse change time

The 8-warehouse + special fertilizer production (such as slow-release fertilizer and bio-fertilizer) realizes multi-element synchronous batching and supports automated production lines

Iii. Suggestions for Selecting Static Batching Machines for Blended Fertilizers

Prioritize matching production demands: If the daily processing capacity is less than 50 tons, select 2 to 4 silos. If the capacity is greater than 200 tons, select 6 or more bins.

For example, a 600-head pig farm generates approximately 657 tons of manure annually. If it is to be used for the production of organic-inorganic compound fertilizer, it is recommended to choose the 4-6 bin model of Zhengzhou Hanke Machinery, with a daily processing capacity of 5-10 tons.

Consider scalability: Choose models that support the expansion of warehouse capacity (such as modular design) to avoid excessively high upgrade costs in the future.

Pay attention to the supporting functions

Automation control: PLC+ touch screen operation, reducing manual intervention

Data traceability: Supports formula storage and production record keeping
