Quotation and selection plan for servo scale organic fertilizer hopper granular packaging scale

The following is a detailed comparative analysis of the organic fertilizer hopper granular packaging scale by Zhengzhou Hanke Machinery, covering core performance comparison, quotation and cost analysis, and selection scheme comparison, for reference by fertilizer factories in selection

I. Core Performance Comparison of Servo Scale Organic Fertilizer with Bucket Granule Packaging Scale

Packaging speed

Single-bucket servo scale: Taking 25 kilograms per bag as an example, the conventional equipment speed is 8-12 bags per minute (480-600 bags per hour), and it is suitable for medium and small-scale production.

Double-bucket servo scale: The speed can reach 40-60 bags per minute (2400-3600 bags per hour), and the efficiency is increased by 3-5 times.

Key difference: The double-bucket scale significantly increases the total output by reducing the single weighing time, making it particularly suitable for large-scale production lines.

Precision and stability

Servo control technology: It adopts high-precision servo motors to drive the feeding mechanism, achieving three-speed (coarse, medium, and fine) feeding, with dynamic accuracy ≤±0.2% and static accuracy ≤±0.1%.

Sensor configuration: The all-stainless steel load cell features impact resistance and corrosion resistance. Its long-term stability is superior to that of ordinary sensors, reducing maintenance frequency.

Ii. Quotation and Cost Analysis of Servo Scale Organic Fertilizer Hopper Granular Packaging Scale

The core differences between the quotations for equipment types: 25 kilograms per bag and 40 kilograms per bag

Single-bucket economic type: 12,000-18,000 yuan, 25,000-35,000 yuan. The weighing module of the 40-kilogram equipment has higher precision requirements, and the price increases by 30%-50%.

Single-bucket high-end type: 32,000-50,000 yuan; 50,000-80,000 yuan. The high-end type is equipped with PLC servo system and intelligent deviation correction algorithm, doubling the price.

The high-end double-bucket scale costs 50,000 to 80,000 yuan and 80,000 to 120,000 yuan. It requires dual-channel synchronous control, which increases the hardware cost by 40% to 60%.

Long-term usage cost

Energy consumption: The efficiency of servo motors is higher than that of ordinary motors. The power consumption of a single-bucket scale is approximately 1.8-2.2kW, and that of a double-bucket scale is about 3.5-4kW. Calculated at 8 hours per day, the daily power consumption of a single-bucket scale is about 14.4-17.6 kilowatt-hours, and that of a double-bucket scale is about 28-32 kilowatt-hours.

Efficiency benefit: Taking a daily output of 200 tons as an example, a double-bucket scale saves 4 to 6 hours per day compared to a single-bucket scale. Calculated at a labor cost of 200 yuan per person per hour, the annual cost savings are approximately 200,000 to 300,000 yuan.

Iii. Recommended Solution for Servo Scale Organic Fertilizer with Bucket Granule Packaging Scale

For medium and small-scale production (≤50 tons per day), single-bucket servo scales and organic fertilizer granule packaging scales are selected

Budget: 32,000-50,000 yuan.

For large-scale production (≥100 tons per day), choose the double-bucket servo scale for organic fertilizer granule packaging

Budget: 80,000-120,000 yuan.
