Hello, I am a salesman at Tongli Heavy Machinery, and today I would like to introduce to you the process of compound fertilizer production. Compound fertilizer is mainly the process of making fertilizer products by mixing a variety of nutrients in reasonable proportion and powder form, so the next will carefully introduce the process flow.

I. Raw material selection and pretreatment

This is the first step and the preparation work. Before using our compound fertilizer production line, you need to prepare all the raw materials, including the main nutrients such as nitrogen, phosphorus, and potassium, as well as containing trace elements. Here are the steps for each aspect.

1. Selection of main raw materials: According to the difference in nutrient demand of different crops, appropriate compounds of main nutrients such as nitrogen, phosphorus, and potassium are selected as main raw materials. For example, urea, ammonium sulfate, potassium chloride, etc.

2. Auxiliary raw materials selection: auxiliary raw materials include trace elements, slow-release agents, synergists, etc., which are selected according to soil conditions and crop needs.

3. raw material quality testing: the selected raw materials for laboratory testing to ensure that their quality meets the standard requirements.

Raw material grinding and formula mixing

The second part is to crush and grind all the selected raw materials (nitrogen, phosphorus, and potassium raw materials), so that the purpose is to make the raw materials evenly distributed and in line with a certain ratio, to grind the particles of uniform size and improve efficiency.

1. raw material grinding: the main raw materials selected are crushed and ground to make the particles of uniform size and meticulousness, to improve the dissolution speed and fertilizer efficiency.

2. Formula mixing: according to the specific fertilization formula and ratio, the main raw materials and auxiliary raw materials are mechanically mixed to ensure that various nutrient elements are evenly distributed.

Granulation process

1. Formula granulation: The mixed formula is ground again through the grinder to make the particles more uniform in size.

2. Granulation: The powdered mixture is fed into the granulator to form granules through extrusion, shearing, and friction while adding the right amount of binding agent for curing. Commonly used granulators are drum granulators, flake granulators, etc.

Drying and cooling

1. drying: the newly made fertilizer granules are sent into the dryer, and the moisture on their surface is evaporated by hot air or cyclone, etc., to improve storage stability.

2. Cooling: The dried fertilizer pellets enter the cooler and are cooled naturally with cold air to reduce the temperature of the pellets and prevent agglomeration caused by high temperatures in the storage and packaging process.

Sieving and packaging

1. Sieving: The cooled fertilizer pellets are sieved to remove the pellets that do not meet the specifications to ensure product quality.

2. Packaging: Fertilizer granules that meet the specifications are sent to the automatic packaging machine for weighing and packaging according to the set requirements, with common forms of packaging such as bagging, bulk, and large packaging.

Quality inspection and finished products factory

1. Quality inspection: assay and test the packaged fertilizer samples to ensure that the nutrient content, moisture content, granule hardness, and other indicators meet the required standards.

2. factory finished products: after passing the quality inspection, the packaging of the finished compound fertilizer can be factory sales or storage use.

The above is the basic process of compound fertilizer production, and in the actual process, the final product standards need to be adjusted and improved, and need to control the process, in order to achieve a certain rate of finished products, we need to continue to optimize the process, as well as the discovery of problems need to be corrected in a timely manner.

The following are 6 important suggestions from us at Tongli Heavy Machinery:

1. Automated production: introduce automated equipment and control systems to improve production efficiency and quality stability. For example, use automatic metering and mixing equipment for ingredient proportioning and mixing, as well as automatic packaging machines for packaging.

2. Balanced adjustment of nutrient elements: Rational proportioning and adjustment of nutrient elements according to the needs of different crops and soils. Laboratory analysis and data statistics can be used to determine the best combination of formulations to improve the application efficiency and crop yield of fertilizers.

3. Additive application: New additives such as retarders, anti-caking agents, and synergists are introduced to improve the effectiveness and durability of fertilizer. These additives can delay nutrient release, reduce nutrient loss and increase crop utilization of fertilizer.

4. Quality control and quality management: Establish a strict quality control system, including strict screening and testing during the procurement of raw materials, quality monitoring, and recording during the production process, and comprehensive inspection before the finished products leave the factory. Meanwhile, a sound quality management system is established to ensure that the products comply with national and industry standards.

5. Application of environmental protection technology: Adopt environmental protection technology and equipment to reduce the emission of waste gas, wastewater, and solid waste in the production process. For example, the use of high-efficiency filters and exhaust gas treatment equipment, wastewater treatment, and reuse to reduce the impact on the environment.

6. R&D innovation: continuously conduct R&D innovation, introduce new production processes and equipment, and develop new fertilizer products. For example, explore new nutrient ratios and compounding techniques, and develop compound fertilizers with special functions and characteristics to meet the needs of different crops and soils.

Summing up

A compound fertilizer production line formed by using our fertilizer machines and fertilizer granulator machine and other machines used to produce compound fertilizer is the best way. Above I have introduced how the compound plate pellets are produced, which raw materials are needed and the various production processes and steps, all of which are sufficient to reflect the production standard of compound fertilizer that meets the standard. Using the compound fertilizer produced by our company can increase your profit and make the fertilizer better and more advanced. By automating production, it is possible to produce a more balanced nutritional product to improve production efficiency.
