TONGLI compound fertilizer production line is equipped with raw material crusher, rotary drum granulator, rotary drum dryer，rotary drum cooler , rotary drum coating machine and other auxiliary equipment. We offer professional process design and supply fertilizer production line capacity ranges from 50,000 tons per year up to 300,000 tons per year.
TONGLI complete set of equipment has a compact process layout, scientific and reasonable, and advanced technology. Energy saving and consumption reduction, stable operation, reliable operation and convenient maintenance. Wide adaptability of raw materials, suitable for granulation of various raw materials such as compound fertilizers, medicines, chemicals, feeds, etc., and the product granulation rate is high. It can produce compound fertilizers of various concentrations and types.
The process flow of compound fertilizer production line can be generally includes: raw material ingredient, raw material mixing, raw material granulation, particle drying, particle cooling, particle classification, finished product coating, final product packaging.
The steam drum granulation production line has wide adaptability to raw materials.
The output of the steam drum granulation production line is high, and the pelleting rate reaches 70%.
Drum granulation is heated by the steam. The moisture content is low after the material is formed into balls therefore the drying efficiency is high.
Main equipment are equipped with manhole doors and observation windows to observe the operation of materials at any time.
The output of the steam drum granulation production line is stable and the service life of the equipment is long.
The Dryer is partially lined with SS304 stainless steel plate to prolong the service life.
The granulator is lined with polymer lining plate, and the liner plate drops due to the gravity to achieve the function of automatic cleaning.
TONGLI has rich experience in the manufacture, installation and commissioning of NPK compound fertilizer drum granulation production line equipment.
Crushing of raw materials: Ammonium chloride, monoammonium phosphate, potassium chloride, and urea are crushed by the bulk crusher，chain crusher，double-cage crusher to the size required by the process.
Raw material batching: The powdered materials are metered by the DCS automatic batching system.
Granulation: The mixed material enters the steam drum granulator to form granules.
Drying: The material that forms granules enters the dryer #1 for primary drying, and then enters the dryer #2 for secondary drying.
Coarse particle primary screening: Screen out the finished products with qualified size, and return the rest to the previous process for re-granulation.
Fine particle secondary screening: screen out the finished products with qualified size, and return the rest to the previous process for re-granulation.
Cooling: The granules with qualified size enter the cooler, where they are cooled and further dehydrated under the action of counter air flow.
Finished Product screening: Screen out the finished products with qualified size, and return the rest to the previous process for re-granulation.
Coating: After screening, the qualified materials enter the coating machine and mix with coating oil and anti-caking agent to produce finished products.
Packing: the finished product is packed by automatic quantitative packing scale. The bag is then automatic folded and automatic sewed.
Palletizing: The packaged finished products are stacked by a palletizer.
