How to choose a compound fertilizer belt scale

When choosing a compound fertilizer belt scale, a comprehensive consideration should be made from core dimensions such as accuracy, measurement range, material, structure, intelligent functions, brand after-sales service and budget. Zhengzhou Hanke Machinery has specifically summarized the following for you:

I. Clarify core demands

1. Material properties

Granular/powdered compound fertilizer

Fluidity (whether it is prone to caking)

Corrosiveness (Chlorine-containing compound fertilizers require anti-corrosion design)

2. Production requirements

Production capacity (1-5t/h small line, 5-20t/h medium line, 20t/h+ large line)

Accuracy requirements (generally ±0.5% to 1%, ±0.2% for high precision)

3. Installation environment

Indoor/outdoor (rain and dust protection requirements)

Space limitations (belt length and inclination Angle)

Ii. Comparison Table of Key Purchasing Parameters for Compound Fertilizer Belt Scales

Parameters: Economy type, Standard type, High-end type

Frame material: Carbon steel with plastic coating, 304 stainless steel, 316L stainless steel

Dust removal configuration: No, simple dust removal hood, pulse reverse blowing dust removal system

Price range: 20,000-50,000 yuan, 50,000-120,000 yuan, 120,000-300,000 yuan

Iii. Key Points of Special Design for Compound Fertilizer Belt Scales

1. Anti-slip belt

Patterned or diamond-patterned belts must be selected (to prevent particles from rolling off).

Chlorine-containing fertilizers need to be coated with polyurethane for anti-corrosion

2. Anti-sticking design

Configure an automatic scraper (to prevent materials from sticking to the belt)

Vibrator-assisted feeding (for fertilizers prone to caking)

3. Intelligent calibration

Dynamic zero-point tracking technology (to avoid errors caused by belt material adhesion)

Automatic zero calibration every 4 hours (optional)

Iv. Maintenance Tips

Daily: Clean the accumulated material on the scraper

Weekly: Check the tension of the belt

Monthly: Calibrate the sensor

Each season: Replace worn idlers

Efficiency enhancement techniques

The belt inclination Angle is ≤15° (to prevent material from sliding down)

Adding 0.5% silicone oil can reduce the sticky material by 50%

Choose the right belt scale and reduce the packaging error of compound fertilizer by 70% directly!
