Category: organic fertilizer granulator

Bioorganic fertilizer refers to a fertilizer that is mainly composed of animal and plant residues such as livestock and poultry manure and crop straw, supplemented by harmless organic materials, and has a dual effect of microbial fertilizer and organic fertilizer. Compared with fertilizers, bio organic fertilizers have a complete set of nutrients and are popular among farmers, such as improving soil, improving product quality, improving crop rhizosphere microbiota, enhancing plant resistance to diseases and insects, promoting the use of chemical fertilizers, and increasing the utilization rate of fertilizers.

There are several types of conventional machinery and equipment for producing organic fertilizers:

Organic fertilizer tipping machine: During the fermentation process, the raw materials are flipped to control the uniformity of fermentation and the temperature at which the raw materials are fermented.

Organic fertilizer crusher: finely crush the fermented raw materials to meet the granulation requirements.

Organic fertilizer mixer: Fully stir and blend the auxiliary materials and raw materials according to the formula requirements, to make their nutritional composition more uniform.

Organic fertilizer granulator: The mixed raw materials are made into predetermined particles using granulator equipment and loaded with organic fertilizer.

Organic fertilizer dryer: Dry the excess moisture in the produced granular organic fertilizer to below 15% for easy storage and increased strength.

Organic fertilizer cooler: The temperature of the dried organic fertilizer particles is very high, and the particles are promptly cooled to quickly cool and shape, and enter the next process.

Organic fertilizer screening machine: Use a screening machine to screen out some unqualified particles, carry out rework and remake, and retain qualified particles for the next process.

Organic fertilizer coating machine: Apply a layer of coating agent evenly on the surface of particles to improve their strength, brightness, and fullness, which is more conducive to preservation.

Organic fertilizer packaging machine: Use an automatic quantitative packaging machine to package particles into bags.

With the continuous development and progress of the production process of organic fertilizer equipment, the manual operation required for organic fertilizer production and processing has gradually decreased, and more importantly, it tends to be automated operation. This production and processing method is not only conducive to management, but more importantly, the quality control of production and processing is strong.

Rotary drum granulator is a kind of molding machine which can be made into specific shape. Rotary drum granulator is a key equipment in compound fertilizer industry, which is suitable for the production scale of cold, hot granulation and high, medium and low concentration compound fertilizer.
The main working mode is the wet granulation of pellets. Through a certain amount of water or steam, the basic fertilizer fully reacts behind the cylinder. Under certain liquid phase conditions, the cylinder rotates and the particles agglomerate into balls under pressure.

The production line process of rotary drum granulator includes raw material batching machine, fertilizer mixer machine, crusher, rotary drum granulator, particle dryer, particle cooler, coating machine for finished product, and quantitative packaging machine for finished product.

Humic acid fertilizer refers to the production of a large amount of humic acid, nitrogen, phosphorus, potassium and some trace elements required by crop growth and development by using different production methods of peat, lignite and weathered coal. Humic acid, as the raw material of organic fertilizer production equipment, plays an important role in agricultural production, such as stimulating crop growth, improving soil, increasing nutrients and strengthening soil microbial activities.

Varieties of humic acid fertilizer

1. Humic acid fertilizers can be divided into two categories: natural humic acid and artificial humic acid according to their sources. Among natural humic acids, they are divided into soil sodium humic acid (white) phytic acid, coal coal humic acid, Water humic acid and mold humic acid, etc. Humic acid can be made into solid particles by NPK fertilizer granulator.

2. Humic acid fertilizers can be divided into primary humic acid and regenerated humic acid (including humic acid in natural weathered coal and artificial oxidized coal) according to the production method.

3. Humic acid fertilizers can be classified into fulvic acid, brown fulvic acid and black fulvic acid according to their solubility and color in solvents. In the earlier literature, there were also names of grey fulvic acid, brown fulvic acid and green humic acid, which were actually separated from different solvents.

4. According to the natural binding state, humic acid fertilizer can be divided into free humic acid and (calcium, magnesium) combined humic acid. We provide humic acid processing equipment, disc granulator, grinder, dryer, etc.

5. Humic acid fertilizer can be divided into type A, type B (true humic acid), RP type and P type (immature humic acid) according to the humification degree of humic acid (such as absorption coefficient).

In a complete fertilizer production line, granulation is the key process in the whole production process. The productivity of organic fertilizer granulator, the strength and shape of granule produced by the granulator directly affect the quality of the final product.

In many fertilizer production enterprises, the most used fertilizer granulation equipment are drum granulator, extrusion granulator and disc granulator. Among the three granulation methods, the disc granulator machine is more suitable for the granulation of organic-inorganic compound fertilizer, and the effect is ideal.

Disc granulator machine is mainly composed of granulation disc, spray system, transmission device, bracket and so on. During production, the powder raw materials are conveyed by the belt conveyor to the granulation disc in the disc granulator. The rotating disc with an inclination of 50° rotates the animal material. When the material is brought to a certain height, its own gravity and inertia Under the action of the force, it breaks away from the disc and slides down along the arc track to complete the rolling required for granulation. At the same time, the liquid injected by the spray system will be evenly sprayed on the rolling material to agglomerate into granules, thus completing The whole granulation process, according to the principles applied in this granulation process, we can call it agglomerate granulation process. With the continuous addition of raw materials, the manufactured particles fall across the edge of the disk under the action of centrifugal force and fall into the belt conveyor equipment below.

As a mature model, the disc granulator has experienced the test of various materials. However, any equipment has its advantages and disadvantages. In the face of different raw materials and production processes, there are also corresponding models. In the actual NPK fertilizer production line, the selection of granulation equipment suitable for materials can make the whole fertilizer production process play a maximum benefit.

There are two common methods to deal with feces in farms
1. Drying treatment. It is the excrement dehydration to facilitate the use, mainly has the natural drying and the high temperature fast drying. Natural drying is to use sunlight to dry livestock manure; high temperature and rapid drying is to dry artificially through a dryer. The commonly used drum dryer can reduce the moisture content of chicken manure from 70% to 75% in a short period of time to less than 8%. However, there are some disadvantages such as the secondary pollution of odor discharged by the dryer and the poor fertilizer efficiency caused by too high treatment temperature.
2. Aerobic composting. Livestock manure contains a lot of organic matter and rich nutrients such as nitrogen, phosphorus, potassium and so on, which is a valuable resource for the sustainable development of agriculture. Therefore, aerobic composting of manure is widely used at present. According to the characteristics of manure raw materials and auxiliary materials, according to the carbon nitrogen ratio and moisture content required for composting, manure and auxiliary materials are mixed in a certain proportion. The fertilizer production machine properly controls the oxygen and temperature in the heap, so that the manure can be rapidly fermented to produce organic fertilizer. The advantages of this method are less odor, more dry, easy to package and apply. It can be used as soil amendment or organic fertilizer in agricultural production.

Steps of making organic fertilizer from manure 
1. Raw material ingredients: chicken manure, pig manure, cow manure, biogas residue and other animal manure or raw materials that can be fermented or have fertilizer efficiency after treatment are equipped in a certain proportion (according to market demand and local soil test results).
2. Mixing of raw materials: Stir the prepared raw materials evenly to increase the uniform fertilizer efficiency content of the overall fertilizer particles.
3. Raw material granulation: Feed the uniformly stirred raw materials into the fertilizer granulator machine for granulation (rotary granulator or extrusion granulator can be used).
4. Granule drying: The granules made by the granulator are sent to the dryer to dry the moisture contained in the granules to increase the strength of the granules and facilitate storage.
5. Granule cooling: The temperature of dried fertilizer granules is too high and easy to agglomerate. After cooling, it is convenient for bagging storage and transportation.
6. Particle classification: The cooled particles are classified, the unqualified particles are crushed and re-granulated, and the qualified products are screened out.
7. Finished film: Coating qualified products to increase the brightness and roundness of the particles.
8. Finished product packaging: Pack the coated particles, which is the finished product, in a ventilated place.

For the installation of the manure dryer of the organic fertilizer equipment, each part needs to be installed in place to ensure that there is no hidden danger in the production process of the equipment. The parts to be adjusted mainly include two sets of small wheels, large gears, installation and sealing of incoming and outgoing materials, etc. How to adjust the big and small gears when installing the manure dryer of organic fertilizer equipment?

1、 Installation of two small wheels of manure dryer for organic fertilizer equipment

After the two sets of small wheels are placed in position, the angle line must be aligned and the two ends of the line must be parallel. If there is a height error, it can be cushioned under the base and treated firmly. The two sides of each set of small supporting rollers must be horizontal. This is very important. It directly affects the stable operation of the whole stool dryer. The adjustment of the two apertures is the second important part after the small roller. First, adjust the left and right balance of the aperture, use the thread adjustment method or the thimble method to adjust by reference, and then adjust the roundness of the aperture. When adjusting, loosen the base plate at the symmetrical position first, and fix it tightly after adjustment. Spot welding can be carried out, and it is appropriate to fix it firmly. Secondly, the gap between the small roller and the large aperture should be uniform, which is mainly determined by adjusting the height and slope of the small roller.

2、 Adjustment of big gear of chicken manure dryer for organic fertilizer equipment

The adjustment of the big gear is the adjustment of the spring steel plate. The adjustment method is the same as the adjustment of the big aperture. The meshing of tooth surface is the key to adjust the big gear. First, the tooth surface should be evenly occluded and pay attention to the slope. Second, the distance between the tooth head and the tooth base is 6mm. The tooth surface should be adjusted evenly on both sides. Use a feeler gauge to check and press the lead wire to check. After the adjustment, the fixation should be completed by applying force and marking. The pinion base shall also be marked for inspection during production. The bridge base must be reinforced and fixed 100% firmly and marked around, and it can be checked once per shift.

The tooth stirring granulator machine is suitable for the granulation of light and fine powder materials. The finer the basic particles of the fine powder material, the higher the sphericity of the particles and the better the quality of the balls.

Disc pelletizer is suitable for granulating organic fertilizer, compound fertilizer, compound fertilizer, organic and inorganic compound fertilizer. Because of the high granulation rate, large hourly output, stable operation, sturdy and durable equipment, and long service life, it has been selected as the ideal granulation equipment by the majority of users.

Drum fertilizer granulator machine raw material is very suitable for large-scale production of cold and hot granulation and high, medium and low concentration organic fertilizers, compound fertilizers. The ball-forming rate reaches 85%, there is a small amount of return material, the size of the return material is small, and it can be re-pelletized.

The material adaptability of the roll extrusion granulator is very extensive. It can be used for granulation of various raw materials such as compound fertilizers, medicine, chemical industry, feed, coal, metallurgy, etc., without drying process, granulation at room temperature and one-time molding.

Organic fertilizer granulator machine: most of the structure of the disc granulator: each machine is composed of components such as a flow bracket, a sorting disc, a sports frame, an ore receiving slot, a feeding slot, and a developing heat pipe. The selection disc is actually a circular table with a degree of taper of l: 0.02. The disc is supported on the motion frame through the core shaft, and there is another circular track on the bottom surface, which is stuck on the supporting roller. The revolving weight and the electric effect and its transmission elements are installed on the sports frame. The sports frame is made of pure steel hoisting on the flow bracket. When the electric effect rotates, the idler pulls the disc to rotate in a 6.5 second turn , Rotate the heavy hammer with a progress of 300 to 400r / min, so that the disk surface shakes in response to the progress.

The task principle of the disc granulator: each machine and the cross-flow transmission belt chute are conceived using Bagnold shear practice and the flow film mining principle. When the slurry is given from the core of the disc to the primary selection area of the disc surface, the slurry is on an inclined surface Moving upwards, the ore group is affected by the flow force and the shearing force caused by the heavy hammer, and the stratification and classification will soon stop. The yield of heavy ores with large particle size and density will first settle on the vertical surface; Heavy minerals and light minerals with large particle size and small density are sinking in the lower part of the vertical plane; light minerals with small particle size and small density are not able to settle and flow to the tailings connection mine. The minerals of various nationalities sinking in the primary selection area were brought back to the selection area by the rotating disc, and were repeatedly washed by the developing water, so that all secondary light minerals flowed to the medium mine slot, and the dense heavy minerals flowed to the fine Mine to mine slot.

The use characteristics of the disc granulator: 

(1) Each machine adopts a heavy hammer installed on the motion frame to shake the selection surface with high frequency rotation, and successive track-type circular activities occur to strengthen the shearing effect of the liquid flow. Moreover, this kind of circling shear force is directional, and can lose a strong evacuation pressure, so that the ore particles are constantly turning on the disk surface, thus slowing down the grading and settling progress of the ore particle group on the disk surface. Improve the quality of the goods and solve the power. 

(2) The sorting surface of each machine is a conical surface, which gradually increases from the feed end to the discharge end. When the pulp is given to the sorting surface, the speed of light of the pulp quickly decreases, and the thickness of the ore layer quickly becomes thin The heavy mineral deposits are displayed from coarse to fine. After entering the selection area, the developer water scatters towards the winding position. The coarse-grained minerals in the upper part are washed down and then settled in the lower part, so that it has two development opportunities above, and the fine-grained items in the collapsed part are once. Indirect flushing to the concentrate trough is beneficial to coarse-grain-level improvement of quality and fine-grain-level recovery.

How to use organic fertilizer composter to ferment manure and process organic fertilizer

The manure from poultry farms contains a large amount of nitrogen, phosphorus, potassium and other nutrients, which is an excellent organic fertilizer. The raw materials of organic fertilizer (livestock and poultry manure, domestic garbage, dead branches and leaves, biogas residue, waste bacteria, etc.) are fermented and then enter the semi-wet material crusher for crushing, and then add nitrogen, phosphorus and potassium and other elements (pure nitrogen, phosphorus pentoxide, potassium chloride, ammonium chloride, etc.) to make the mineral elements meet the required standards, and then have a mixer for mixing, After entering the granulation mechanism, the particles will be dried, screened by the screening machine, and the qualified products will be packaged, and the unqualified ones will be returned to the organic fertilizer granulation machine for granulation.

However, before use, it is necessary to kill the pathogenic microorganisms, parasitic eggs and other harmful substances in the feces to prevent them from polluting the farmland, causing the farmland odor and burning seedlings. The small manure organic fertilizer production line is based on some domestic farms, such as chicken farms, pig farms, cattle farms, and other chicken dung, livestock dung, as raw materials to ferment and produce small amounts of organic fertilizer, to solve the problem that the stench of chicken dung, pig dung, and cow dung can not be handled in time, and the price of this set of equipment is low, which is acceptable to most farms.

The organic fertilizer equipment configuration includes pulverizer, mixer, organic fertilizer granulator, screening machine and packaging machine. The small organic fertilizer production line manufacturer has a complete set of equipment of 50000 to 60000 yuan. The equipment investment is small, but a large amount of labor costs need to be invested in the later stage.

Selecting the appropriate manure treatment equipment for livestock and poultry farms can not only protect the environment and realize the healthy development of green animal husbandry, but also improve the economic benefits of the farms and achieve ecological sustainable development.

Organic fertilizer production line is a streamlined production operation mainly composed of a new organic fertilizer granulator machine. Each of them is very important. Especially in the production process, the idler determines whether the production is running efficiently. There is a traditional use of the organic fertilizer equipment production line. The characteristics add luster to people, and it is widely understood what kind of performance they have.

1) First of all, the raw materials such as animal manure are fermented and rotten. 

2) Secondly, use the semi-wet material crusher of organic fertilizer crushing equipment to decompose the raw materials.

3) Matching raw materials is one of the most important processes in organic fertilizer production. 

4) After the material is uniformly mixed, mechanical granulation is required, which is also a crucial aspect of the entire production process.

5) The raw material obtains high-temperature energy after the drying step. 

6) Sieving is to sieve out unqualified granule fertilizer. 

7) The blended raw materials are used to produce granules, which are especially suitable for materials with high viscosity.

8) The material of the mixing vessel must be able to meet the standards required for production, such as pressure resistance, temperature resistance, resistance to catalyst erosion, and keep the product clean.
