Many fertilizer manufacturing factories intend to take urea, granular phosphate and potash fertilizer as main raw materials to make BB fertilizer. However, newly built plants often encounter frequent troubles including material segregation, bulk caking, uneven nutrient distribution and poor appearance of finished fertilizer products.

In practice, it is not technically difficult to produce BB fertilizer from urea and other fertilizer materials. Manufacturers only need to strictly control several core links including raw material screening, formula matching, mixing operation and finished product storage, so as to continuously obtain qualified BB fertilizer. This mature production mode fits newly constructed fertilizer factories and also supports process upgrading for existing production workshops.

Raw Material Selection Standards to Produce BB Fertilizer from Urea and Other Fertilizer Materials

The whole production of BB fertilizer relies on physical mixing instead of chemical reaction. Therefore, the quality of raw materials directly decides the stability of finished goods. Reasonable raw material screening acts as the first critical step to produce BB fertilizer from urea and other fertilizer materials, which can avoid most common faults during continuous mass production.

Choose Urea Raw Materials with Uniform Particle Size and Qualified Dryness

Urea is the most widely used nitrogen raw material for BB fertilizer. Many factories ignore particle uniformity and moisture index when purchasing urea. Wet or irregular urea particles are easy to absorb moisture and form lumps after mixing, which brings hidden troubles when you produce BB fertilizer from urea and other fertilizer materials.

Match Phosphorus and Potassium Fertilizer Raw Materials with Similar Particle Size

Serious segregation easily occurs after mixing if the particle size gap between urea and phosphate, potash fertilizer is too large. Keeping similar particle specification of all raw materials is an effective measure to reduce segregation when you produce BB fertilizer from urea and other fertilizer materials.

Avoid Mixing Incompatible Raw Materials That Absorb Moisture Easily or Trigger Chemical Reactions

Some fertilizer raw materials will absorb moisture rapidly or produce chemical reactions once contacted. Operators need to make a clear compatibility list before batching. Blind material collocation will cause caking and failure when you produce BB fertilizer from urea and other fertilizer materials.

Screen Out Powder, Lumps and Other Impurities in Advance

A large amount of powder and hard blocks mixed in raw materials will break uniform mixing effects. Factories need to set up screening procedures before feeding. Removing impurities in advance helps maintain stable quality when you produce BB fertilizer from urea and other fertilizer materials.

Practical Proportion Guidelines to Produce BB Fertilizer from Urea and Other Fertilizer Materials

Manufacturers do not need complicated computing formulas for formula design. Operators can adjust raw material proportion according to target crops and local soil testing data to get BB fertilizer with balanced nutrients and low caking risk. Scientific and flexible formula design supports factories to steadily produce BB fertilizer from urea and other fertilizer materials.

> Adjust Urea Adding Proportion According to Crop Nutrient Demand

Different crops have distinct demand for nitrogen elements. Too high urea content may lead to excessive vegetative growth, while insufficient nitrogen restricts yield. Adjusting urea proportion reasonably is essential when you produce BB fertilizer from urea and other fertilizer materials.

> Differentiate Basic Formulas for Field Crops and Fruits and Vegetables

Field grain crops, fruits and vegetables have different absorption rules of nitrogen, phosphorus and potassium. Separating basic formulas can improve fertilizer utilization efficiency. Targeted formula arrangement helps you produce BB fertilizer from urea and other fertilizer materials to meet market demands.

> Appropriately Add Trace Element Granules to Raise Fertilizer Utilization Rate

According to soil deficiency status, manufacturers can add granular trace element raw materials. Adding trace components properly improves the comprehensive effect of finished BB fertilizer, and makes products more competitive when you produce BB fertilizer from urea and other fertilizer materials.

> Fine Tune Production Formulas Based on Raw Material Moisture Conditions

The moisture of urea and other raw materials fluctuates in different seasons. Operators need to slightly adjust formulas or add anti-caking auxiliary materials according to real-time moisture test, preventing quality fluctuation when you produce BB fertilizer from urea and other fertilizer materials.

Standard Production Workflow to Produce BB Fertilizer from Urea and Other Fertilizer Materials

Different from organic fertilizer or compound fertilizer granulation lines, BB fertilizer made from urea does not require granulation and drying links. The whole process consumes less power and cuts overall production cost. Medium and small fertilizer plants can adopt this mature workflow to continuously produce BB fertilizer from urea and other fertilizer materials.

1. Complete Automatic and Accurate Batching of Multiple Raw Materials

Raw materials including urea, potash fertilizer and phosphate fertilizer are transported to independent silos. The dynamic batching system weighs each material automatically according to set formulas. Accurate batching forms the foundation if you want to produce BB fertilizer from urea and other fertilizer materials.

2. Carry Out Uniform Granular Material Mixing Under Stable Running Speed

After batching, all materials are sent into the rotary drum mixer. Constant rotating speed avoids particle crushing and uneven mixing. Maintaining stable mixing parameters guarantees uniform nutrients when you produce BB fertilizer from urea and other fertilizer materials.

3. Take Samples and Test Finished Materials for Nutrient Uniformity

After mixing, workers take random samples from finished materials for nutrient inspection. Timely sampling test can find abnormal proportion at an early stage, and avoid large batches of unqualified goods when you produce BB fertilizer from urea and other fertilizer materials.

4. Realize Automatic Quantitative Packaging and Sealing

Qualified mixed materials are delivered to the automatic packaging scale for fixed-weight bagging and sealing. Tight sealing reduces moisture absorption during storage, protecting finished quality after you produce BB fertilizer from urea and other fertilizer materials.

Common Operational Errors When You Produce BB Fertilizer from Urea and Other Fertilizer Materials

Uneven nutrients, caking and segregation of finished BB fertilizer mostly come from improper field operation instead of equipment defects. Avoiding these typical mistakes can greatly lift product quality when you produce BB fertilizer from urea and other fertilizer materials.

Too Big Particle Size Difference Leads to Segregation Shortly After Mixing

Many factories ignore particle matching work. Once the size gap between urea and potash fertilizer is too large, materials will separate again after mixing. It is the most frequent error when new plants produce BB fertilizer from urea and other fertilizer materials.

Excessive Moisture of Raw Materials Causes Caking During Warehouse Storage

Raw materials with high moisture will absorb more moisture after mixing. Finished fertilizer forms hard blocks after several days of stacking. Controlling raw material dryness cannot be ignored if you want to produce BB fertilizer from urea and other fertilizer materials.

Overlong Mixing Time Wears Urea into Fine Powder

Too long mixing cycle will cause mutual friction between particles. Complete urea granules turn into powder, breaking particle consistency. Reasonably setting mixing duration is necessary when you produce BB fertilizer from urea and other fertilizer materials.

Unstable Feeding Speed Brings Continuous Proportion Deviation

Sudden increase or decrease of feeding volume disturbs automatic batching accuracy. Operators need to keep stable feeding rhythm to avoid formula deviation when you produce BB fertilizer from urea and other fertilizer materials.

Lack of Moisture Proof Measures for Stacked Finished Fertilizer Causes Secondary Moisture Absorption

Even qualified BB fertilizer will absorb moisture from air without sealed storage. Factories need to arrange moisture proof management for finished goods after they produce BB fertilizer from urea and other fertilizer materials.
