What is the price range for biological fertilizer packaging scales?

The biological fertilizer packaging scale is a quantitative weighing and packaging equipment specifically designed for biological fertilizers (powdered, granular, or block-shaped). Its core function is to achieve precise portioning of high-humidity, sticky, and bacterial residue and fibrous materials. The mainstream specifications range from 10 to 50 kg per bag, with an accuracy of ±0.2% to ±0.5%, and an efficiency of 8 to 12 bags per minute.

I. Core Types of Biological Fertilizer Packaging Scale (According to Material Form)

Granular/Columnar Biological Fertilizer Packaging Scale (Double Bucket/Single Bucket)

Suitable for fertilizers with uniform particles and good fluidity (such as granular microbial fertilizers and column-shaped organic fertilizers).

Features: Three-level feeding (coarse/medium/fine), alternate feeding by two hoppers, high speed, accuracy ±0.2%.

Powdered biological fertilizer packaging scale (belt type / screw type)

Suitable for powdery biological fertilizers with high humidity (20% - 40%), sticky properties and containing fibers.

Features: Anti-blocking for material feeding, adaptive calibration, fully enclosed stainless steel silo to prevent moisture and dust.

Irregularly shaped block-shaped biological fertilizer packaging scale (belt feeding + weighing)

Applicable to block-shaped fertilizers containing straw and microbial residue. Automatically adjusts weighing parameters to adapt to mixed materials.

II. Key technical parameters of the biological fertilizer packaging scale (main models)

Weighing range: 10 - 60 kg per bag (commonly 25/40/50 kg)

Packaging accuracy: ≤ ±0.5% (for high-end products, ±0.2%)

Packaging speed: 8 - 12 bags per minute (approximately 500 - 700 bags per hour)

Power Supply/Power: 220V/380V, 1.5–2.2kW

Contact material: 304 stainless steel (anti-corrosion, compliant with organic standards)

Control: 7-inch touch screen, automatic zero-point tracking, error correction, out-of-specification alarm

III. Core Functions of the Biological Fertilizer Packaging Scale

Precise weighing: High-precision sensor + dynamic compensation. Automatically calibrates when humidity fluctuates, with parameter fine-tuning taking only 0.5 seconds.

2. Anti-blocking and anti-sticking: Belt/arc gate feeding, suitable for high-humidity materials, with minimal residue and easy cleaning.

3. Intelligent Control: Pre-set multiple specifications, automatic accumulation, fault indication, RS232/485 communication.

4. Safe and durable: Fully enclosed dust-proof design, stainless steel cylinders/sensors, suitable for dusty and humid environments.

IV. Price Range of Biological Fertilizer Packaging Scale (Reference for 2026)

Semi-automatic (manual bagging): 3–80,000 yuan (basic model, accuracy ±0.5%)

Fully automatic (automatic bagging/sewing): 8 - 150,000 yuan (mid-range, accuracy ±0.2%)

High-end customization (dust removal/labeling/fully automated): 15 - 300,000 yuan

V. Key Points for Selecting Biological Fertilizer Packaging Scales

Matching materials: For granular materials, choose double-bucket type; for powdery materials, choose belt type. For high-humidity materials, adopt a structure that prevents adhesion first.

2. Accuracy requirement: For the high-end market, ±0.2% is sufficient; for the general market, ±0.5% is adequate.

3. Production capacity: Small factories choose semi-automatic, while large factories choose fully automatic (≥ 500 bags per hour).

4. Material Standards: The materials in contact with the products must be 304 stainless steel, meeting the hygiene requirements of organic agriculture.

VI. Suggestions for Packaging Scale of Bio-fertilizer

Combine the sewing machine / heat sealing machine with the conveyor, forming a "weighing → sewing → conveying" production line.

Select dust removal devices for high-dust environments to keep the workshop clean.

VII. Recommend some manufacturers of biological fertilizer packaging scales

In terms of reliable manufacturers, Zhengzhou Hanke Machinery is a local professional company that specializes in the research and production of fertilizer packaging scales. It offers a wide range of models, from the basic models priced at 20,000 yuan to the high-end dual-bucket models priced around 100,000 yuan. These models are suitable for various types of biological fertilizers, including granular and powdered ones. The manufacturer directly supplies the products and has a fast response to after-sales services.

When choosing equipment, one should not only consider the price, but also take into account one's own production capacity, material characteristics and budget. Do you not know how to select a cost-effective packaging scale based on your type of biofertilizer (granular/powdered) and daily production volume?
