Bulk Blending Fertilizer Production line

The main raw material particles of Bulk Blending Fertilizer Production line include the following:

Nitrogen fertilizer:
Urea: a common high nitrogen fertilizer with about 46% nitrogen content.
Ammonium Nitrate (Ammonium Nitrate): contains about 34% nitrogen.
Ammonium sulfate: contains about 21% nitrogen.

Phosphorus fertilizer:
Monoammonium phosphate (MAP): contains about 11-13% phosphorus and 21% nitrogen.
Diammonium phosphate (DAP): contains about 18% phosphorus and 46% nitrogen.
Potash fertilizer:
Potassium chloride (MOP): contains about 60% potassium.
Potassium sulfate (SOP): contains about 50% potassium and also provides sulfur.

Micronutrient fertilizers:
Borax, Zinc Sulfate, Manganese Sulfate, Copper Sulfate, Iron Sulfate, Ammonium Molybdate.

These granules are precisely proportioned and homogeneously mixed to form BB fertilizers with specific formulations and functions to meet the nutritional needs of different crops.

Bulk Blending fertilizer production line process:

Raw material conveying:

Conveying speed: the conveying speed of belt conveyor or screw conveyor is usually 1-2 m/s, bucket elevator is used for vertical conveying of raw materials, the lifting height is usually 2-10 meters, and the lifting speed is 0.5-1 m/s.

Conveying distance: usually in the range of 20-50 meters, depending on the layout of the production line.

Batching (dynamic batching machine)

Batching accuracy: usually required to be within ±0.5% to ensure the accuracy of the formula.

Batching system: including multi-bin system, the capacity of each bin is usually in the range of 5-50 cubic meters, depending on the production requirements.

Mixing (Drum Mixer)

Mixing time: typically 5-10 minutes per batch to ensure homogeneity of the material.

Mixing uniformity: the coefficient of variation (CV) is generally required to be less than 5%, i.e., the distribution of the components in the mixed fertilizer is uniform.

Mixing equipment capacity: the mixing capacity of a single batch is usually 2-10 cubic meters, depending on the production scale.

Packaging:

Packaging specification: common packaging specification is 10kg, 20kg and 50kg/bag.

Packaging speed: 200-400 bags/hour, depending on the model and specifications of the packaging machine.

Packaging accuracy: generally required to achieve ± 0.2%.

Detailed process steps and parameter control:

Bulk Blending Fertilizer Production line Raw material conveying and storage:

Raw material feeding control: through the feeding control valve and sensor, to ensure that each raw material enters the dosing system according to the set speed and proportion.

Dust control: In the process of raw material conveying, use dust removal equipment, such as bag filter, to control the dust concentration below 10mg/m³, in line with environmental standards.

Bulk Blending Fertilizer Production line Batching system:

Measuring system: use electronic dosing scale or loss-in-weight dosing scale to ensure accurate proportioning of each raw material.

Automatic control: PLC automatic control system is used to automatically adjust the feeding amount of each raw material according to the preset formula.

Material fluidity: Ensure the good fluidity of each raw material to avoid blocking phenomenon.

Bulk Blending Fertilizer Production line Mixing process:

Mixer speed: usually 30-60 rpm, adjusted according to the characteristics of the material.

Mixing order: add the main material first (such as nitrogen fertilizer, phosphate fertilizer), and then gradually add the secondary ingredients (such as trace elements) to ensure the mixing effect.

Bulk Blending Fertilizer Production line Packaging link:

Packaging machine setting: set the weighing range and sealing parameters of the packaging machine according to the packaging specifications.

Quality Inspection: After each batch of packaging is completed, random sampling inspection is carried out to ensure that the packaging weight and sealing quality meet the requirements.

Label printing: automatically print and paste the label, which includes product name, net weight, production date and other information.

Bulk Blending fertilizer production line advantages:

Automation control: PLC control system and human-machine interface (HMI) are adopted in the whole process to realize automation and real-time monitoring of the production process.

Data Recording and Tracing: Ingredients, mixing and packaging data are automatically recorded for easy quality tracing and management.

Safety Protection: Safety protection devices, such as emergency stop buttons and guardrails, are installed in key equipment and operating areas to ensure safe operation.

By controlling these key parameters in detail, the BB fertilizer production line can run efficiently and stably to ensure that the product quality meets the requirements.

Bulk Blending fertilizer production line Final mixing effect:

Uniform distribution of ingredients: each fertilizer ingredient is uniformly distributed in the mixture without obvious stratification or segregation.

Uniform mixing of particles: particles of different colors and types are evenly mixed together, and the overall appearance is that the particles of various colors are evenly distributed.

Uniformity of mixing: Visual inspection and laboratory analysis ensure that the content of each ingredient in each sample is consistent with the formulation.
