How to choose a compound fertilizer quantitative packaging machine? Attached are the selection tips.

Compound fertilizer quantitative packaging machine is an automated equipment specifically designed for the quantitative weighing and packaging of compound fertilizer granules (or powder). It is widely used in fertilizer manufacturing enterprises. Its core function is to precisely divide compound fertilizer into packaging bags according to preset weights (such as 10kg, 25kg, 50kg, etc.) and complete the sealing and other processes. When purchasing and using it, the following points should be focused on:

I. Key Points for Selection and Purchase

1.Clarify packaging requirements

Weight specification: Determine the common single-bag weight (such as 25kg as the main one, and whether 50kg is needed as well), to avoid a mismatch between the equipment's measurement range and the requirements, which could lead to a decrease in accuracy.

Capacity: Calculated by "number of bags packaged per hour" (for example, fully automatic machines typically package 30 to 60 bags per minute). Ensure that the equipment capacity is slightly higher than the actual demand to reserve a buffer space.

Specify the type of packaging bag: clearly indicate whether it is a woven bag, composite bag or paper bag, as well as the sealing method (sewing, heat sealing, or stapling), to ensure that the sealing mechanism of the equipment is compatible.

2. Core configuration stability

Feeding mechanism: Granular compound fertilizer can be selected for feeding by screw (high precision) or belt (fast speed); powder compound fertilizer needs to be fed by dust-proof screw or vacuum feeding.

Weighing system: It is recommended to choose "Dual-speed feeding" (fast feeding + slow feeding). Fast feeding improves efficiency, while slow feeding ensures accuracy and reduces over-run error.

The control system should support touchscreen operation, be capable of storing multiple sets of parameters (such as different weight specifications), and have fault alarm functions (such as bag absence, overweight/underweight alarms).

3. Weather Resistance and Maintenance

The overall protection level of the equipment: The compound fertilizer workshop may be damp or dusty. Therefore, IP54 or higher protection should be selected to prevent the motor and circuit from being damaged by moisture.

Wear parts replacement: The feeding port, sealing rings and other easily worn components should be easy to disassemble and replace, and the manufacturer should provide sufficient spare parts to reduce downtime.

4. Compliance and Environmental Protection

Comply with industry standards: For instance, the measurement accuracy of packaging machines must be certified by the national metrology department to avoid subsequent quality inspection disputes.

Dust control: If local environmental protection requirements are strict, models with built-in dust removal devices should be selected, or dust removal interfaces should be reserved for connection to the central dust removal system in the workshop.

II. Selection Process and Risk Avoidance

Parameter confirmation: Clearly define key parameters such as material characteristics (density, particle size), packaging speed, and bag size with the supplier, and obtain a customized solution.

Field investigation: Prioritize manufacturers that offer trial use of sample machines, test the packaging effects of different particle varieties, and verify the accuracy and stability.

After-sales guarantee: Confirm that the supplier has a self-diagnosis system for faults (with code prompts for maintenance), a rapid response service, and the ability to supply spare parts, to reduce the risk of downtime.

Brand and reputation: Refer to industry cases (such as the repurchase rate of granulation plants), and choose brands with mature technology to avoid a sharp increase in maintenance costs due to low-priced equipment in the future.

Through the above steps, enterprises can precisely match the functions of plastic granule packaging machines with their actual needs, and balance the initial investment with the long-term operational benefits.
