Agro Phos (India) Limited

Manufacturing Process

1. Single Super Phosphate (SSP)

Our manufacturing process starts with procurement of raw materials. Major raw materials required for manufacturing of SSP is Rock Phosphate and Sulphuric acid. The procurement of Rock Phosphate is fulfilled by importing the same from countries like Egypt, Iran, Jordan, Morocco, Syria, Togo, Tunisia, etc. The requirement of Sulphuric acid is met by purchasing the same from local vendors. After the procurement of raw materials, the manufacturing process starts in Grinding mill where Rock Phosphate is grinded and then the grinded rock phosphate is moved to mixer where Sulphuric acid and water is added. The mixture is then mixed properly and is moved via the den machine to cutter to cut the huge chunks of mixture into powder form. Our Company manufactures both powder and granulated SSP. The manufacturing process of powdered and granulated SSP is same till the mixing process and after this process the mixture is then treated separately.

After the mixing process, the mixture is then moved for further curing process, wherein the drying and mixing of SSP takes place and samples of the final product is sent to the in house laboratory for testing and quality check to ensure that the final product contains the required chemical composition. Once the samples pass the final quality check the product is then sent to hopper for packing the same into HDPE bags for dispatch.

After the mixing process, the mixture is then moved for further curing process, wherein the drying and mixing of SSP takes place. After the curing process the mixture is moved via crane to granulation drum where water is added and then the granulated mixture is moved via conveyor belt to dryer drum wherein the mixture is heated at a temperature of around 1000 degree Celsius. After the heating process, the mixture is then moved to the cooler drum to extract moisture and then the product moves to the vibrating screen to ensure that the granules are of adequate and required size. The samples of granulated SSP now move to the in house laboratory for final testing and quality check and to determine whether the product contains the required chemical composition or not. After the samples pass the final quality check, the product is then sent to hopper for packing the same into HDPE bags for dispatch.

2. Nitrogen Phosphorus and Potassium (NPK)

Our manufacturing process starts with procurement of raw materials. Major raw materials required for manufacturing of NPK is Nitrogen, Phosphate and Potassium. After the procurement of raw materials, actual manufacturing process starts with Granulation as the first step. In this step, raw materials are mixed with water to form granules. These granules are then moved to the drying drum via conveyor belt to dry the granules. After this process, the granules are moved to the coolant drum to extract moisture and then the product passes through the vibrating screen to ensure that the product is available in various sizes. The final product then passes a quality check in the in house laboratory to ensure that the final product is of adequate quality and contains the required chemical composition. Our Company manufactures NPK of varied chemical compositions. Our in house laboratory checks whether different types of NPK contains the required chemical composition as per the said chemical formulae. We use gazette bags for packing of our products. These bags are very easy to handle and facilitates easy stacking as well.

3. Organic Manure

Our manufacturing process starts with procurement of raw materials. Major raw materials required for manufacturing of organic manure is Neem DOC, Castor DOC, Karanja DOC, Mahua DOC and Tobacco dust. These raw materials are procured from the local market and before the manufacturing process the raw material undergo a quality check to check the final quality and chemical composition.

These raw materials are feeded in the hopper as per the required chemical composition, stated as under:

  • Neem DOC: 30%
  • Castor DOC: 25%
  • Karanja DOC: 5%
  • Mahua DOC: 5%
  • Tobacco dust: 35%

The chemical composition of the required raw materials can be changed depending upon their availability.

After feeding the raw materials in the feeder, the materials are then moved to the blending machine via conveyor belt. The materials are blended properly in the blender and then the mixture moves to the drying machine to extract moisture from the final product.

The next process is the quality check to ensure that the final product is of adequate quality and contains the required chemical composition. If the final product passes the quality check, then the same is packed into HDPE bags for final dispatch. We use gazette bags for packing of our products. These bags are very easy to handle and facilitates easy stacking as well.

4. Soil Conditioner (Calcium Sulphate)

Our manufacturing process starts with procurement of raw materials. Major raw materials required for manufacturing of soil conditioner is calcium sulphate, magnesium sulphate and sulphur. All the required raw materials are procured from the local market.

After the procurement of raw materials, the raw materials undergo a quality check to ensure that the raw materials are of required quality. The actual manufacturing process starts with Granulation as the first step. In this step, raw materials are mixed with water to form granules. These granules are then moved to the drying drum via conveyor belt to dry the granules.

After this process, the granules are moved to the coolant drum to extract moisture and then the product passes through the vibrating screen to ensure that the product is available in various sizes. The final product then passes a quality check in the in house laboratory to ensure that the final product is of adequate quality and contains the required chemical composition.

Our product, soil conditioner is sold under the brand name ― “Ratna”.

Our Company manufactures soil conditioner of a notified chemical composition mentioned below: Soil Conditioner (20, 10, 10): This fertilizer contains 20% Calcium Sulphate, 10% Magnesium Sulphate and 10% Sulphur

After the procurement of raw materials, the raw materials undergo a quality check to ensure that the raw materials are of required quality. The actual manufacturing process starts with Granulation as the first step. In this step, raw materials are mixed with water to form granules. These granules are then moved to the drying drum via conveyor belt to dry the granules.
