Introduce of fertilizer rotary drum granulator line
This high yield fertilizer rotary drum granulator line is in solid materials, adding a certain amount of water or steam to form a suitable solid-liquid ratio, solid-liquid materials under the action of equipment, roll to form particles. Whether the production of organic fertilizer or compound fertilizer, only a variety of basic fertilizers are mixed together to produce finished products through drum granulation equipment.
Advantage of fertilizer rotary drum granulator line
The production line can produce both organic fertilizer and inorganic fertilizer, with high pelletizing rate and high yield.
Low investment, quick effect, good economic benefit and reliable performance.
Small power, no waste discharge, stable operation, convenient maintenance, reasonable process layout, advanced technology, low production cost.
It has high pelleting strength, good appearance, corrosion resistance, wear resistance and low energy consumption.
1.Batching: For many kinds material weighting and send to next machine.
2.Crushing: Crush the big material to small powder
3.Mixing: Mixing the different materials fully.
4.Granulation: Processing all kinds of powder materials to small granules.
5.Primary drying: Drying the wet granules.
6.Dedusting: Remove the dust in granulation production
7.Secondary drying: Dry the moisture contained in the particle again, strengthen the hardness of the particle, the product quality is good
8.Primary screening：Sieve a small amount of powder.
9.Cooling: Cooling the granules.
10.Secondary 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.
11.Crushing returned materials: Crush bigger granules from screening machine.
12.Coating: Coating on the surface of fertilizer particles, can effectively prevent the organic fertilizer caking.
13.Packing: Automatic quantitative packaging of powder and granules, suitable for flour, starch, feed, food, chemical industry, light industry, building materials industries.

Main machinery of fertilizer rotary drum granulator line
Drum granulator: Rotary drum granulator is a kind of machine which can make materials into round particles. It is suitable for cold and hot granulation and can be produced on a large scale. The main way of work is wet granulation of pellets. Through a certain amount of water or steam, the basic fertilizer reacts sufficiently after humidification in the cylinder. Under certain liquid conditions, with the help of the rotation of the cylinder, the extrusion force between the particles of the material can be agglomerated into pellets. The pelletizing rate of the machine is up to 70%. There is a small amount of returned material. The returned material has small particle size and can be re-granulated.
Rotary screener machine: Screening process is continuous. Raw materials enter the machine, materials smaller than sieve hole size pass through the sieve hole, and materials larger than sieve hole size are continuously discharged from the screen surface. The machine is suitable for fine screening of fertilizer particles.
Dryer machine: Dryer machine is mainly used to produce fertilizer with a certain temperature and granularity, and it also can be used for drying other materials.Through the fan will be heated gas into the container, to achieve the drying effect. Rotary dryer machine: It has the characteristics of beautiful appearance, simple operation, low energy consumption, long service life, uniform drying, easy maintenance and so on. The rotary dryer is a more advanced drying equipment for compound fertilizer in China, The rotary dryer is mainly used for drying the fertilizer production in a certain temperature and grain of the fertilizer.
Rotary cooler machine: Rotary cooler machine cooling a certain temperature of granular fertilizer, with the use of dryer machine, can greatly improve the cooling speed, reduce labor intensity, increase production, further remove part of moisture and reduce the granular temperature of fertilizer.
Auxiliary machinery of fertilizer rotary drum granulator line
Belt conveyor: Convey the materials continuously, transfer returned materials. It can be used for horizontal transportation or inclined transportation.
Hot air stove: The hot air stove is a necessary related equipment, in the drying process, which provides the necessary heat source for the drier system.
Cyclone dust collector: it is mainly used for pre dust removal and separation and recovery of high concentration dust, widely in fertilizer production, chemical dustry, mining, metallurgy, refractories, building matrials.
We are a professional fertilizer process machinery enterprise in China, has strong technical strength in fertilizer machines. We provide the above equipment, and can design the fertilizer rotary drum granulator line drawing according to your site.
