Factory Supply Slow Release Compound NPK Fertilizer Granulation Production Line Machinery
Introduce of Factory Supply Slow Release Compound NPK Fertilizer Granulation Production Line Machinery
The main machine in the NPK fertilizer production line is Rotary Drum Granulator machine, it is a granulating machine for making materials into a specific shape. The main work principle is pelleted by wet method. By adding a certain amount of water or steam into the materials, the materials play full chemical reaction after being humidified. Under certain liquid phase conditions, extrusion pressure is generated by the drum rotating and the materials agglomerated into balls under this pressure. The drum of this machine is lined with special rubber sheet or acid-resistant stainless, which can automatically prevent materials from sticking to the drum wall without traditional scraper device. There is no waste discharge in the production process. It has the advantages of high yield, corrosion resistance and wear resistance.
The annual output can be 30,000 tons. As a professional fertilizer production line manufacturer, we also supply the clients with other granulation lines with different production capacity, such as 20,000 T/Y, 50,000T/Y, and 100,000T/Y, etc.
The main equipment of Factory Supply Slow Release Compound NPK Fertilizer Granulation Production Line Machinery as follows:
NPK fertilizer production line usually consists of Crusher machine--Batching system--Mixer machine--Granulator machine--Dryer machine--Cooler machine--Screener machine--Coating machine--Packing machine--Conveyor system.
| No. | Main Equipment | Function |
| 1 | Crusher machine | Crush granular raw material to powder. |
| 2 | Batching system | Weighing each kind material automaticlly. Save labor costs. |
| 3 | Mixer machine | Mixing raw material, add water when mixing. |
| 4 | Granulator machine | Make raw material to ball shape granules. |
| 5 | Dryer machine | After granulating, granules moisture is about 30%-40%, need to dry with hot air, this machine need to work with Burning Furnace to supply hot air. |
| 6 | Cooler machine | After drying, granules temperature is high with moisture, need to cool with air. |
| 7 | Screener machine | Separate different size granules, products go to Coating machine. Oversize granules crush and re-granulate, small particles re-granulate. |
| 8 | Coating machine | Granules coating with auti-caking agent, slow release agent etc... |
| 9 | Packing machine | Packing granules in bags, avalible 5-10kgs & 20-50kgs & 500-1000kgs |
| 10 | Conveyor system | Connect the machines in the line, have many types, like Belt conveyor, Screw conveyor, Bucket elevator etc... |
| Auxiliary machines, optional | ||
| 11 | Steam boiler | Adding steam to Granulator machine, melting urea granules. |
| 12 | Burning furnace | Work with Dryer machine, burning fuel to supply hot air, fuel type:Coal/Natural gas/Wood/Diesel/Biogas etc... |
| 13 | Powder spray & Melting tank | Supply powder or liquid agent to Coating machine. |
| 14 | Dust collector | 1.Client build the Dust collector room according to the drawing. |
| 15 | Installation accessories | Platform, Ladder, Stands etc... |
Advantages of Factory Supply Slow Release Compound NPK Fertilizer Granulation Production Line Machinery:
1.High Granulation Rate, 70%, have less small particles need re-granulate again, these small particles are easy to make granules when re-granulate. Large granules will be break and re-granulate again, there is no waste in the production.
2.It adopts Cold & Hot granulating/ High content and Low content Compound fertilizer large capacity production.
3.It is wet granulating line, need add water or steam when granulating, can heating fertilizer and melting fertilizer to help material granulating with less moisture, granules is easy to dry and cool.
4.Low investment, good economic benefit and reliable performance.
5.High pellet strength, good appearance, corrosion resistance, wear resistance, low energy consumption.
