How to select a type of compound fertilizer packaging machine

The selection of BB fertilizer packaging machines should focus on three core aspects: the material characteristics of BB fertilizer (multiple particle mixtures, prone to dust, and significant differences in fluidity), packaging specifications, and production capacity requirements. The key issues to be addressed are "accurate quantification, anti-clogging and anti-sticking, dust prevention and environmental protection, and wear and corrosion resistance." The following is a structured selection guide to assist agricultural production enterprises in making purchasing decisions:

I. Core selection criteria for compound fertilizer packaging machines (first clarify the requirements)

1.Key parameters of material properties

Particle size specification: Blended fertilizers are mostly mixed particles ranging from 0.5 to 8mm (including different particles such as urea, phosphate, and potash fertilizers). It is necessary to confirm whether there are powder or damp components (the moisture content should be no more than 12% for the best result; otherwise, it is prone to caking).

Fluidity: Large differences in particle density (such as urea density at 1.33g/cm³ and potassium fertilizer at 1.98g/cm³) can lead to uneven fluidity, causing "layered feeding" and affecting the accuracy of quantification.

Corrosiveness: Some blended fertilizers contain chloride ions (such as potassium chloride type), and the equipment contact parts need to be corrosion-resistant.

2. Packaging and Capacity Requirements

Packaging specifications: The mainstream ones are 10kg/bag, 25kg/bag, and 50kg/bag (industrial large packaging can be up to 100kg/bag).

Capacity requirement: Calculate backward based on "daily output" (for example, if 50 tons of blended fertilizer need to be packaged daily and the 25kg/bag specification is selected, 2000 bags/day are required, corresponding to equipment speed ≥ 15 bags/minute).

Automation requirements: manual feeding (suitable for small workshops), semi-automatic (with manual bag clamping assistance), fully automatic (automatic feeding + quantitative control + sealing + conveying).

II. How to Select the Right Model for Blended Fertilizer Packaging Machines for Enterprises

The core of selecting a compound fertilizer packaging machine is "dedicated model + compatible configuration + controllable cost":

Small enterprises: Semi-automatic quantitative packaging scales (18,000 to 45,000 yuan), meeting basic production needs.

Small and medium-sized enterprises: Fully automatic double-bucket weighing and packaging machine (45,000 to 120,000 yuan), balancing efficiency and accuracy.

Large enterprises: Four-bucket weighing + intelligent linkage production line (120,000 to 250,000 yuan), suitable for mass production and modern management.
