Purchasing Guide for Servo Compound Fertilizer Granule Double-Bucket Packaging Scale

The following is a detailed guide to the servo compound fertilizer granule double-bucket packaging scale, covering the quotation range, key points for selection, and precautions for installation and commissioning. It is suitable for the large-scale production needs of large fertilizer factories

The quotation range for the servo double-bucket packaging scale is 80,000 to 180,000 yuan per unit

Note: The price difference mainly depends on the material (304 vs carbon steel), the brand of the servo motor, the degree of automation (whether it includes automatic bagging and dust removal systems), etc.

2. Key configurations affecting quotations

Weighing range: Commonly 50kg per bag. Customized 25kg to 100kg requires structure adjustment (±5% cost).

Additional features

Automatic bagging device (+ 30,000-60,000 yuan)

Dust removal system (+ 10,000-30,000 yuan)

Robot palletizing integrated Interface (+ 20,000-50,000 yuan)

Ii. Key Points for Selecting Servo Double-Bucket Packaging Scales for Compound Fertilizer Granules (Special for Compound Fertilizer Granules)

Core performance requirements

Weighing accuracy, corrosion resistance

Processing capacity: The two buckets work alternately, and the theoretical speed should reach 600 to 1000 bags per hour (50kg per bag).

2. Key component brand suggestions: servo motor, load cell, control system

3. Special design requirements

Dust-proof sealing: Compound fertilizers generate a lot of dust, so the motor and sensors must have an IP65 protection level.

Anti-clogging material structure: High-molecular lining plates or pneumatic vibration devices are installed on the inner walls of the hopper.

Compatibility: Reserved interfaces support switching between different bag types (woven bags /PE bags).

Iii. Installation and Commissioning Process of Servo Compound Fertilizer Granule Double-bucket Packaging Scale

1. Preparations before installation

Site requirements: Horizontal hardened ground (load-bearing capacity ≥2 tons /m²), with a 1.5m maintenance space reserved around the equipment.

Power supply: 380V±10%, 50Hz, separately grounded (resistance < 4Ω).

Auxiliary equipment: Feeding belt conveyor (height matching with packaging scale, inclination Angle ≤30°).

Air compressor (providing a stable air source of 0.6MPa for pneumatic bag clamping).

2. Debugging steps

1. Mechanical installation: Calibrate the levelness of the double buckets (error ≤0.1mm/m), and tighten the anchor bolts. Connect the gas path and the circuit, and check that the sensor has no lateral force interference.

2. Parameter Settings: Input particle density (typically 1.2 to 1.5g/cm³), target weight, and feeding speed (the recommended ratio of fast/medium/slow is 70%/20%/10%).

3. Trial operation: Test the action sequence of each motor and cylinder under no-load conditions. When conducting load tests, calibrate the load cell with standard weights (for example, the error at the 50kg point is ≤20g).

3. Common Problem Handling

Unstable weighing: Check if the sensor shielding wire is interfered with or if the particles have clumped, causing uneven feeding.

Bag clamping and material leakage: Adjust the Angle of the bag clamping device or replace the wear-resistant silicone gasket.

The speed does not meet the standard: Optimize the ratio of fast/medium/slow feeding time, or increase the volume of the hopper.

For large-scale compound fertilizer factories, it is recommended to choose servo granular double-bucket packaging scales (priced between 120,000 and 150,000 yuan). The focus should be on the anti-corrosion design and feeding stability. During installation, the sensors must be strictly calibrated. Regular maintenance should be carried out in the later stage to ensure long-term accuracy.
