ISO Rotary Drum Granulator In Compound Fertilizer Production Line

Raw material for producing compound fertilizer

Compound fertilizer is the fertilizer containing two or all three of the three basic plant nutrients—Nitrogen, Phosphorus, and Potassium, as well as microelements, such as B, Mn, Cu, Zn, and Mo. The raw material can be powder or bulk, mostly are as below:

Flow chart of compound fertilizer production line

Compound fertilizer production line usually includes 9 processes, batching, grinding, mixing, granulating, drying, cooling, screening, coating and packaging. Batching, mixing, granulating, drying, and screening processes are necessary. Other processes are optional based on different capacity.

1. Crusher machine

Crush granule or lump material to small powder. (Is the urea powder type or granule type in your line?)

2. Batching machine

For many kinds material weighting and send to next machine

2. Mixing machine

The mixed material should be mixed completely ,then get into granulator .

3. Granulation machine

Processing powder to granules.

4. Drying

After granulating, the moisture of fertilizer is bit high ,it’s not suitable for long-term storage so need drying process.

5. Cooling

The cooling machine is used to cool the hot fertilizer.

6. Screening

There are some non-uniform particles ,after sieved screening machine , the small particle diameter may be screened down for twice processing. And bigger granules go to the crusher machine again.

7. Crusher machine

For bigger granules from screening machine.

8. Coating machine

For compound fertilizer coating

9. Packaging

Filling the bags, and sealing. After package ,the fertilizer can be sold .
