What is the Layout of Phosphate Fertilizer Granulation Plant?
This production line can be divided into four areas: raw material stacking area, raw material processing area, aging area and granulation area. The division of labor varies from region to region.
Above this area you will need to install a shed. You must keep the phosphate rock well in the stockpiling area because it cannot be wet later in the process. In addition, the area of this storage area is about 400 square meters, and you can adjust it according to your requirements.
Processing Area(Grinding and Acidification)
In the raw material processing area, you need to have a manure shredder and Raymond milling system. Because these two pieces of equipment pretreat the phosphate rock to facilitate subsequent acidification and granulation. Then these phosphate rocks in the acidification plant, you will feed the phosphate rock powder into the double shafts horizontal mixer through the screw feeder.
And there is also a stainless steel sulfuric acid storage tank above the mixer. Sulfuric acid flows out from inside and is fully mixed with phosphate rock powder in the mixer. After that it is sent to the acidification neutralization tank through the screw conveyor.
Tips:After acidification, the phosphate rock powder will become a paste, and it still needs to be pulverized afterwards. You can use a vertical grinder, but the blades will need to be changed frequently because the material is very corrosive. Then you can forklift feed to the aging area.
The area of the secondary aging area is about 400-500 square meters. Here, the acidified phosphorus material is subjected to aging treatment. So you need to reserve enough space for aging materials.
Tips:This step is to help the acidified phosphate rock powder reduce moisture, because the moisture before aging is 50-60%.
In the granulation area, you can equip disc pelletizer or double roller granulator according to your budget. Or if you don’t want to granulate, you can skip this step and pack it directly.
Fertilizer Production Projects for Making Powder and Granular Phosphate Fertilizer
In general, most phosphate fertilizer manufacturers prefer to prepare phosphate fertilizer into two forms. Powdery and granular. So in order to meet the different requirements of our customers, we especially design powdery phosphate fertilizer making line and granular phosphate fertilizer production line separately.
Powdery Phosphate Fertilizer Making System Design
Powdery phosphate fertilizer manufacturing line is a simple process to make phosphate rocks into fertilizer. So only needs a few fertilizer machines, it can help you finish phosphate fertilizer making. Including vertical crusher, Raymond milling system, double shafts horizontal mixer, stainless steel sulfuric acid storage tank, loader type feeder, crusher, powder screening machine, batching machine, mixer, packaging machine and belt conveyor.
Can Powder Fertilizer Make System Produce Phosphate Fertilizer in a Large Scale?
Of course. The largest capacity of SX powder phosphate fertilizer making line can reach 30t/h. If you want to produce more capacity, you can customize equipment. But it has lower investment, less area occupation, high automatic,etc. Therefore, it is a hot selling product for customers those who start phosphate fertilizer manufacturing initially. About a year,even less.
Granular Phosphate Fertilizer Production Project Technology
When you want to further process phosphate fertilizer,you can choose to turn powder phosphate fertilizer into granules. Then because of more complicated process, it needs more phosphate fertilizer machines. Generally, a complete granular phosphate fertilizer preparation line contains loader type feeder, crusher, powder screening machine, batching machine, mixer, granulator, pellet screening equipment, dryer, cooler, coating machine, packaging machine, dust collector and belt conveyor. Removing the material’s treatment. You can choose them to design your own plan for phosphate fertilizer production project according to your needs.
Does Granular Phosphate Fertilizer Making Line Need a Large Investment?
Don’t worry, we can design phosphate fertilizer making line according to your budget. Moreover, the feedback from our past customers showed that they usually make profits in a short time.
Which Method is Suitable for you to Choose for your Phosphate Fertilizer Production?
If you want to operate phosphate fertilizer granulation plant, there are something you should know about the phosphate fertilizer making process. Here we provide you two methods for your phosphate fertilizer granular production: wet and dry granulation process.
Wet Granulation Processing for Phosphate Fertilizer Production
Using wet granulation processing technology for phosphate fertilizer production, it is suitable for you add water or vapor into phosphate fertilizer powders during the granulation process. This processing technology is a main method for compound fertilizer manufacturing. Meanwhile, for your different processing requirements, we provide pan granulation and rotary drum granulation machine for processing phosphate compound fertilizer.
But it is worth noting that the two granulation equipment should be lined with stainless steel to prolong the service life. Because the acidified phosphate rock powder is very corrosive and will damage the equipment.
Another phosphate fertilizer production process is dry extrusion phosphate fertilizer producing. It takes advantages of extrusion force for pressing dry phosphate fertilizer powders into pellets. If you use this method for making phosphate fertilizer granules, you do not add binders or liquid for improve the adhesive force. Moreover, it can reduce consumption of dry process, which saves your budget. For you information, it is suitable for you to process the powders, whose moisture content is under 5%.
How to Deal with the Exhaust Gas in the Phosphate Fertilizer Production Process?
In the process of acidifying phosphate rock powder, a lot of fluorine gas will be produced, including hydrofluoric acid and fluosilicic acid. In the context of environmental protection in the world now, if you directly use the chimney to discharge, it will definitely pollute the surrounding air. Therefore, in response to this situation, SX specially design a water curtain dust collector system, which can effectively discharge hydrofluoric acid and fluosilicic acid. If your budget is not enough, you can also build your own reservoir for discharge treatment.
