30,000 ton organic fertilizer production line

Short Description 

The annual production line of 30,000 tons of organic fertilizer is to convert all kinds of organic waste into organic fertilizer through different processes. Bioorganic fertilizer factories can not only turn chicken manure and waste into treasure, producing economic benefits, but also reducing environmental pollution and producing environmental benefits. The shape of particles can be cylindrical or spherical, which is easy to transport and use. The device can be selected according to your actual needs.

Product Detail

We provide the process design and manufacture of a new buffer granulation production line for organic fertilizer. The production line equipment mainly includes a hopper and feeder, a new buffer granulation machine, a dryer, a roller sieve machine, a bucket hoist, a belt conveyor, a packaging machine and other auxiliary equipment.

Organic fertilizers can be made of methane residue, agricultural waste, livestock and poultry manure and municipal waste. These organic waste needs to be further processed before they are converted into commercial organic fertilizers of commercial value for sale. The investment in converting waste into wealth is absolutely worthwhile.

Rich organic raw material resources

Organic fertilizer raw materials are rich in resources, which are mainly divided into the following categories. Different materials can be combined with different production equipment:

1. Animal excrement: such as chickens, pigs, ducks, cattle, sheep, horses, rabbits, etc., animal residues, such as fishmeal, bone meal, feathers, fur, silkworm manure, biogas pools, etc.

2. Agricultural waste: crop straw, rattan, soybean meal, rapeseed meal, cottonseed meal, silk melon meal, yeast powder, mushroom residue, etc.

3. Industrial waste: wine slurry, vinegar residue, cassava residue, filter mud, medicinal residue, furfural slag, etc.

4. Municipal sludge: river mud, sludge, ditch mud, sea mud, lake mud, humic acid, turf, lignite, sludge, fly ash, etc.

5. Household garbage: kitchen waste, etc.

6. Diction or extract: seaweed extract, fish extract, etc.


Production line flow chart



1. Semi-wet material crusher is used to make it more adaptable to the moisture content of raw materials.

2. The particle coating machine makes the spherical particle size uniform, the surface is smooth, and the strength is high. Suitable for connecting with various granulators.

3. The whole production line is connected by belt conveyor and other supporting equipment.

4. Compact structure, stable performance, convenient operation and maintenance.

5. The device can be selected according to your actual needs.


Work Principle

The process includes fermentation equipment, mixer, granulation machine, dryer, cooler, roller sieve machine, silo, fully automatic packaging machine, vertical crusher, belt conveyor, etc. The basic production process of the whole organic fertilizer includes: grinding of raw materials → fermentation → mixing of ingredients (mixing with other organic-inorganic materials, NPK≥4%, organic matter ≥30%) → granulation → packaging. Note: this production line is for reference only.

1. Drum dumper

The fermentation process fully decomposes the organic waste into fermentation and ripening. Different plugs such as walking dumpers, double-helix dumpers, grooved plugs, groove hydraulic dumpers and tracked dumpers produced by our company can be selected according to actual composting raw materials, venues and products.

2. Crushing machine

The fermented raw material enters the vertical chain grinder, which can crush raw materials with a water content of less than 30%. The particle size can reach 20-30 orders, which meets the granulation requirements.

3. Horizontal mixer

After crushing, add the auxiliary material according to the formula and mix evenly in the blender. Horizontal mixer has two options: a uniaxial mixer and a double-axis mixer.

4. A new organic fertilizer granulator

The qualified granulation rate of the machine is as high as 90%, which is suitable for a variety of different formulas. The compressive strength of the particles is higher than that of disk granulation and drum granulation, and the large spherical rate is less than 15%.

5. Round thrower

The rounding machine can repair and beauty the granulation particles after granulation. After extruding granulation or disk granulation process, after throwing rounding, the fertilizer particles can be uniform in size, accurate roundness, bright and smooth on the surface, large particle strength, and the spherical yield of fertilizer is as high as 98%.

6. Dry and cool

The roller dryer continuously pumps the heat source in the hot air stove at the nose position to the tail of the engine through the fan installed at the tail of the machine, so that the material is in full contact with the hot air and reduce the water content of the particles.

The roller cooler cools particles at a certain temperature after drying, and reduces the water content of particles again while reducing the particle temperature.

7. Roller sieve

It is mainly used for separating finished products from recycled materials. After sieving, qualified particles are fed into the coating machine, and unqualified particles are fed into the vertical chain crusher to regrainate, thus achieving product classification and uniform classification of finished products. The machine adopts a combined screen, which is easy to maintain and replace. Its structure is simple, easy to operate and smooth. Steady, it's an indispensable equipment in fertilizer production.

8. Packaging machine:

The coating of qualified particles through a rotary coating machine not only makes the particles beautiful, but also improves the hardness of the particles. The rotary coating machine adopts special liquid material spraying technology and solid powder spraying technology to effectively prevent fertilizer particle blocking.

9. Automatic packaging machine:

After the particles are coated, they are packaged by the packaging machine. The packaging machine has a high degree of automation, integrating weighing, suture, packaging and transportation, which realizes rapid quantitative packaging and makes the packaging process more efficient and accurate.

10. Belt conveyor:

The conveyor plays an indispensable role in the production process, because it connects different parts of the entire production line. On this compound fertilizer production line, we choose to provide you with a belt conveyor. Compared with other types of conveyors, belt conveyors have large coverage, making your production process more efficient and economical.
