Technical Points and Selection Guide for Urea Granule Filling Machines

The urea granule filling machine is an automated quantitative packaging equipment suitable for urea granules (with a particle size of 1-4mm and a moisture content of ≤1%). Its core functions include automatic feeding, metering filling, bag clamping and sealing, and finished product conveying. It features corrosion resistance, anti-caking, and precise metering. The following are the technical and selection points of the urea granule filling machine:

I. Core Configuration and Technical Requirements (Specific to Urea Characteristics)

1.Corrosion-resistant material

Components in contact with urea (hoppers, metering bins, screw/vibrating feeders) should be made of 304 stainless steel to prevent weakly acidic corrosion of equipment caused by moisture absorption of urea and to extend service life.

2. Anti-caking and anti-bridging design

Install vibration arch-breaking devices or agitators in the silo to prevent urea particles from caking due to moisture absorption and blocking the discharge port.

The feeding port is designed with a large diameter and is equipped with variable frequency speed regulation to ensure smooth material discharge.

3. Control of Measurement Accuracy

It adopts a weighing sensor + PLC control system, supports "fast addition + slow addition" stepwise feeding, automatically compensates for the drop difference during discharging, and the packaging accuracy of urea granules can be stably maintained at ±0.2% to ±0.5%, meeting the packaging standards of the fertilizer industry.

4. Dust-proof and Environmental Protection Configurations

Install a pulse dust removal system to absorb the urea dust generated during the packaging process, prevent dust leakage from polluting the environment, and protect the health of the operators at the same time.

5. Sealing accessory equipment

5-50kg bagged: Matched with automatic sewing machine (thread-sealed) or heat sealer (laminated bag), the sealing is firm and moisture-proof.

Ton bag packaging: Equipped with lifting strap reinforcement device to prevent bag damage during lifting.

II. Core Points for Model Selection

1.Select the model based on packaging specifications and production capacity.

For small-scale retail (1-10kg), choose a screw-type quantitative packaging scale, which balances accuracy and efficiency.

Conventional large bags (25-50kg): Vibration type quantitative packaging scales are preferred, offering high cost performance.

For bulk wholesale (ton bags): Choose ton bag packaging machines to meet the requirements of large-scale shipments.

2. Venue and Supporting Conditions

It is necessary to reserve space for the production line of feeding, packaging and conveying. The small single machine occupies about 3-5 square meters, and the large ton bag machine occupies about 10-15 square meters.

The air compressor (0.6 - 0.8 MPa) is provided to drive the pneumatic bag clamping and arch-breaking devices, ensuring the stable operation of the equipment.

3. Cost Reference

Small spiral packaging scale: 80,000 - 150,000 yuan;

Medium-sized vibrating packaging scale: 150,000 - 300,000 yuan;

Large ton bag packaging machine: 500,000 - 1,000,000 yuan (including dust removal system).
