A Purchasing Guide for Specialized Double-Hopper Granular Fertilizer Packaging Machines

The dual-hopper packaging machine for granular fertilizers is a device used for fertilizer packaging. Generally, it quantitatively weighs and packages fertilizers through electronic weighing technology and microcomputer control. For instance, some packaging machines use a self-flowing vibration feeding method, which can evenly distribute the fertilizers from the storage hopper to the feeding device, thus completing the packaging process.

The fertilizer-specific double-bag packaging machine is mainly applied in industries such as feed, grain, metallurgy, medicine, petrochemicals, non-metallic minerals, fine chemicals, inorganic salts, rubber and plastics, leather, and chemical fertilizers. It is suitable for packaging various granular fertilizers.

I. Clarify Requirements

1.Determine the range, accuracy and packaging speed.

Before purchasing, it is necessary to determine the measurement range, accuracy and packaging speed of the selected equipment. For example, different fertilizers have different packaging specifications, and the required measurement range is also different. Some granular fertilizers may require a measurement range of 5 - 50kg; in terms of accuracy, it is generally required to reach ±0.2%; the packaging speed is determined according to actual production needs, such as the packaging speed of viscous powder may be 80 - 20 bags per hour.

2. Consider production requirements

Understand your hourly output requirements for the granular fertilizer-specific double-hopper packaging machine. The hourly output of the fertilizer double-hopper automatic weighing packaging machine is usually around 10 to 20 tons. If the output demand is larger, you may need to choose a larger model or combine multiple devices; if the output is smaller, choosing a suitable specification of equipment can avoid resource waste.

3. Clearly define the usage occasions.

When choosing a packaging machine, it is necessary to consider the specific application environment. If the environment is poor, such as in a production workshop with a lot of dust and high humidity, a machine of better quality from a reputable brand should be selected. However, if the environment is relatively good, a more cost-effective product can be chosen. For instance, in a workshop with significant dust and high humidity, the packaging machine must have good protective performance.

II. Understand Product Features

1.Applicable Materials

The dual-bucket packaging machine for granular fertilizers is mainly suitable for various types of fertilizers. It can also be used for quantitative packaging of granular materials in industries such as grains, rice seeds, chemicals, and food. It is also applicable for packaging granular materials with good fluidity, such as compound fertilizers, blended fertilizers, organic fertilizer granules, urea, rubber granules, plastic granules, biomass granules, feed, and BB fertilizers.

2. Functional Features

Measurement and Speed: It features high measurement accuracy, fast packaging speed, stable performance, and easy operation. For instance, it adopts high-precision sensors, high-speed AD sampling processing, and anti-interference technology to achieve automatic error correction and compensation, ensuring accurate measurement.

Control intelligence: The large display touch screen constitutes the core of the drive control, maximizing the control accuracy, reliability and intelligence level of the entire machine. Some packaging machines adopt large, medium and small three-level feeding, with the forced execution function in the simulation state, truly achieving self-diagnosis of faults, which is convenient for maintenance and repair.

Environmental-friendly design: Some packaging machines adopt a closed internal circulation system, effectively preventing dust from flying, improving the working environment and protecting the health of operators.

3. Material Selection

The packaging machine is available in materials such as carbon steel and stainless steel. The selection of materials for parts that come into direct contact with the material needs to take into account the characteristics of the fertilizer, such as whether it is corrosive or not. If the fertilizer is somewhat corrosive, the material of the bearing components needs to consider the reliability of mechanical action in a corrosive environment.

III. Investigation of the Manufacturer's Situation

1.Business qualifications

It is necessary to have a thorough understanding of the manufacturer's business qualifications. Choose manufacturers with a good market reputation and those that provide high-quality products. This can ensure the performance and durability of the equipment. Equipment produced by regular manufacturers is of higher quality and more reliable in terms of after-sales service and other aspects.

2. Technical support and training

It is very important to know whether the manufacturer provides necessary technical support and operation training. Professional technical support can help users better use and maintain the packaging machine and reduce the impact of equipment failure on production.

3. After-sales Service

Choose a manufacturer that offers good after-sales service so that problems can be solved promptly during use. For example, Zhengzhou Hanko Machinery Factory can solve problems on-site for faulty products within a short time. For users in other regions, the manufacturer will also provide specific solutions.

4. Price and Cost

The price range of the double-hopper automatic weighing and packaging machine for fertilizers in the market varies widely, from several thousand to over a hundred thousand. When comparing quotations from different manufacturers, make sure the selected equipment meets the budget requirements. At the same time, factors such as the quality, performance and after-sales service of the equipment should also be comprehensively considered. One should not only focus on the price.

5. Other Precautions

When consulting the manufacturer, you should explain the situation of packaging materials, packaging equipment (such as bag size, material, etc.), expected output, etc., so that the manufacturer can provide you with suitable machine models. In addition, you also need to understand the manufacturer's delivery cycle, payment methods and other information. For example, some manufacturers have a delivery cycle of 3 to 5 days after placing an order, and products in stock will be dispatched within a short time; all products support online payment or on-site purchase, etc.
