Compound fertilizer for mixed fertilizer double bucket granule packing scale selection guide

For the purchase of compound fertilizer with mixed fertilizer double bucket pellet packaging scale, combined with technical parameters, performance characteristics, brand strength and after-sales service and other core elements, the following is a detailed purchase guide:

First, core selection elements

1. Suitable material characteristics

Particle hardness: Acid fertilizer is easy to absorb moisture and caking, need to prevent bridge design (vibration hopper/forced feed).

Corrosivity: chlorination or sulfur-based fertilizers require 316L stainless steel contact parts.

Mixing uniformity: double bucket independent weighing, dynamic compensation to avoid stratification (error ≤±0.5%).

2. Capacity demand

Package Specifications Economy (4-6 bags/min) Standard (8-10 bags/min) High speed (12-15 bags/min)

40-50kg single bucket (such as HK-K50B) Dual bucket (such as HK-KS50B) Dual bucket + automatic traction (high-end)

3. Precision control

Dual weight bucket alternate feeding: reduce waiting time, improve speed.

Three-stage feed (fast/medium/slow) : coarse feed screw + fine feed vibratory disk to ensure ±0.3% accuracy.

4. Device compatibility

Material adaptation: granular materials with good fluidity such as mixed fertilizer, compound fertilizer and feed particles should be supported.

Packaging specifications: Confirm that the device supports multi-specification presets (such as 20 pre-stored formulations) for flexible adjustment of packaging quantities.

Second, performance characteristics analysis

Double bucket structure advantage

Alternating working mode: dual scales operate independently, reducing waiting time and improving packaging efficiency.

High precision guarantee: Dual bucket design reduces the risk of accumulation of single weighing error by alternating calibration.

Material and durability

Contact parts: Full 304 stainless steel is preferred (such as Xinyuan technology equipment) to avoid damage to equipment caused by corrosive fertilizers.

Dustproof design: It is required to be equipped with a closed internal circulation system or dust removal device to prevent dust pollution.

Degree of automation

Intelligent functions: automatic drop correction, zero tracking, overshoot suppression and other functions can improve measurement stability.

Auxiliary configuration: infrared induction sewing machine, automatic statistics of packing quantity and other design to reduce manual intervention.

3. Choose a strategy

Zhengzhou Hanke Machinery:

Configuration flexibility: Provide no bucket/single bucket/double bucket full system configuration, support customized design.

Price transparency: factory direct supply model, no middleman price difference.

Through the above analysis, it can be combined with the actual production capacity, budget and after-sales service needs of the enterprise to choose the appropriate double-bucket particle packaging scale.
