fertilizer granulator Sep 26, 2023

As we all know, the production of organic fertilizer requires the use of organic fertilizer granulators, such as roller granulator, tooth stirring granulator, disc granulator machine, new organic fertilizer granulator, npk fertilizer granulator, etc, but the production granular organic fertilizer dryer is also very important, especially in the wet granulation fertilizer production line, the dryer is very helpful for drying fertilizer granules, and the raw material of the wet granulation equipment is always high in water content. Before granulation, the material is always dewatered by about 30% with a solid-liquid separator. But this value is not suitable for the final particle. In order to make the particle structure more compact and increase its hardness, a dryer is required. Once dry, the transport and storage of fertilizer granules is much easier.

Features of organic fertilizer rotary drum dryer:

1. High degree of mechanization and great working ability. At the same time, it consumes less fuel and does not require manual operation when working. This can greatly reduce the cost of hiring operators.

2. Our drum dryer has good high temperature resistance characteristics, which ensures fast drying of fertilizers and materials. This dryer is much taller than conventional dryers.

3. The distribution and angle design of the lifting plate is very reasonable, which makes the performance of the machine more reliable and stable. Therefore, it greatly improves the utilization rate of thermal energy and reduces the frequency of material cleaning.

4. It has good applicability to different fertilizer materials such as poultry manure, livestock, mushrooms, straw powder, sawdust and so on. No matter the material, our rotary dryers can work for you.

5. Our dryer can also sterilize and deodorize fertilizer while drying it. This will not only allow the fertilizer to have the proper amount of moisture, but it will also be used in a better amount.

fertilizer granulator Sep 26, 2023

Straw organic fertilizer production equipment has low investment, less land occupation, high profits, and good benefits. The organic fertilizer production line equipment is suitable for direct granulation of coarse fiber organic waste with a moisture content of about 30%, such as fermented livestock and poultry manure, sugar factory filter mud, urban sludge, papermaking sludge, liquor tank, straw, peat, etc. It can produce pure organic fertilizer, organic inorganic compound fertilizer, and bio organic fertilizer with spherical particles. How much does it cost to establish an organic fertilizer processing plant and invest in small organic fertilizer equipment? The environmentally friendly organic fertilizer production line is a complete set of production equipment that uses animal and plant residues such as fresh chicken manure, cow manure, pig manure, sheep manure, and solid waste straw as raw materials, and undergoes a series of processing treatments to produce natural organic fertilizers.

Characteristics of straw organic fertilizer production equipment: The organic fertilizer production line requires two steps to process commercial organic fertilizer: the pre fermentation and treatment part and the deep processing and granulation part. The supporting equipment for biological organic fertilizer requires equipment such as fermentation and composting machines, organic fertilizer crushers, drum screening machines, horizontal mixers, disc granulators, rotary dryers, cooling machines, screening machines, coating machines, packaging machines, conveyors, etc.

Straw organic fertilizer production equipment and technology:

1. Straw treatment: Firstly, the straw crusher should crush the material to a certain fineness, and then an appropriate amount of poultry manure or sludge must be added to adjust the carbon nitrogen ratio and moisture content of the compost material, or add bacterial strains and enzymes.

2. Fermentation: There are two stages: first, pre fermentation, which can be carried out in the open air or in a fermentation device. Oxygen is supplied to the stacking layer or fermentation device through forced ventilation through a flipping pile, and livestock and poultry manure is added with straw as the main body. The main fermentation period of aerobic composting is about 3-10 days. The second is post fermentation, where the semi-finished products that have undergone the main fermentation are sent to the post fermentation process to further decompose the easily decomposable organic matter and the more difficult to decompose organic matter that have not yet been decomposed in the main fermentation process, turning them into stable organic matter such as humic acids and amino acids, and obtaining fully decomposed organic fertilizer products. The post fermentation time is usually more than 20-30 days.

3. After fermentation treatment: It can be further dried and crushed as needed to turn the material into qualified organic fertilizer raw materials.

4. Storage: Compost is generally used in spring and autumn, and must be stored in summer and winter. The storage method can be directly stored in a fermentation tank or in bags, and it is required to be dry and breathable.

Straw organic fertilizer production equipment and technical advantages:

1. Straw organic fertilizer is a type of fertilizer with guaranteed quality. The quality is even better than animal manure, which contains a certain amount of heavy metals;

2. Wheat straw and other raw material resources are abundant and cost-effective;

3. The future market space is vast, and with the implementation of green production increase models in China this year, organic fertilizers will become increasingly scarce.

The Technology of the Stirring Tooth Granulator for Animal and Poultry Manure Granulation Equipment

fertilizer granulator Sep 18, 2023

The pollution problem of livestock and poultry manure has attracted strong attention from society. Under environmental pressure, more and more farms are starting to solve it, attempting to change the current passive situation. Faced with enormous environmental pressure, large-scale livestock farms in various regions are seeking breakthroughs in the utilization of manure. Processing livestock and poultry manure resources into organic fertilizers is undoubtedly a win-win approach that can meet environmental requirements and achieve income and value-added. Practice has proven that using animal manure organic fertilizer production line to produce organic fertilizer is a relatively effective harmless treatment and resource utilization method for large-scale pig farms.

The animal manure granulation equipment, the stirring tooth granulation machine, is designed and manufactured using a wet continuous push rod granulation process. This machine can not only granulate various organic substances, especially coarse fiber materials that are difficult to granulate using conventional equipment, such as crop straw, wine residue, bacterial residue, pharmaceutical residue, animal manure, etc., after fermentation, they can be granulated, but also achieve good granulation effects for raw materials such as humic acid and urban sludge.

The animal manure granulation equipment is composed of a body part, a granulation rotor part, and a transmission part. The rotor of the stirring tooth granulator is driven by the motor and reducer of the transmission device. The transmission part and the body part are mostly fixed on the same frame, which not only has a sturdy structure, smooth operation, but also is very convenient to install. It is a new era of environmentally friendly fertilizer production equipment.

The livestock and poultry manure granulation equipment adopts a specialized organic fertilizer granulation machine, which can create solid spherical particles at a moisture content of 20% to 40%, greatly saving energy and equipment, and improving efficiency. During the drying process, there are special polishing and blending functions to make the particles smoother. It can be pure organic fertilizer granulation, or organic or inorganic fertilizer granulation, with no special requirements for granulation materials.

The working principle of the stirring tooth granulator for animal manure granulation equipment is that materials enter the machine from one end of the feeding port of the body, and are continuously pushed through the granulation rotor and mechanically moved with the machine casing to achieve the purpose of granulation. The finished particles are pushed out of the machine at the other end of the body.

How to improve the granulation efficiency of organic fertilizer granulators?

fertilizer granulator Sep 18, 2023

The organic fertilizer granulator is an important machine for the production of organic fertilizer and plays a very important role in the organic fertilizer production industry. Common organic fertilizer granulators on the market include: roller extrusion granulator, stock granulator, disc granulator machine, new organic fertilizer granulator, new two-in-one organic fertilizer granulator, flat die granulator, ring die granulator, various granulators have their own production characteristics, and the fertilizer granulator machine price varies.

The organic fertilizer granulator machine increases the amount of returned material, and reduces the granulation temperature and water content, which are sensitive methods to reduce large particles. Therefore, when using a granulator for an environmentally friendly organic fertilizer granulator, the method of adjusting the amount of steam and the amount of returned material is often used to adjust the granulation effect of the granulator. The granulation effect is mainly to avoid chemical changes caused by moisture agglomeration and progress of fertilizers, resulting in deterioration of fertilizers.

The characteristics of the raw material fertilizer of the environmentally friendly organic fertilizer granulator determine the granulation performance. Due to the different granulation methods, attention should be paid to conditions such as powder characteristics, moisture, and circulation. Of course, these conditions are all related to the adjustment of the liquid phase amount. Environmentally friendly organic fertilizer granulator generally has moderate solubility, easy to granulate, and insoluble is not easy to granulate. For example, urea decaside ash requires a narrow rate of change in water content and is difficult to granulate. Heating is often used to improve solubility and granulation, granulation is carried out under heating conditions for drying during the granulation process. Therefore, under low temperature conditions, the salt will melt when heated, resulting in a saturated solution with high concentration, which has high plasticity and is conducive to granulation.

Regular calcium is a porous substance, and water becomes a buffer to maintain viscosity. Because the presence of gypsum increases the granulation capacity of the organic fertilizer granulator, it is convenient to use ordinary calcium to produce low-concentration compound fertilizers for granulation.

Working principle and characteristics of drum granulator

fertilizer granulator Sep 18, 2023

Organic fertilizer granulator is one of the most core equipment in organic fertilizer material equipment, which has a direct impact on the quality of organic fertilizer particles (roundness, uniformity, fertilizer moisture retention performance, etc.). Different granulation processes for organic fertilizers require different types of granulators, which directly affect the yield, quality, appearance, price, and other aspects of the product. It can be said that the organic fertilizer granulator is the core of the entire production line.

The working principle of the drum granulator is that the main motor drives the belt and pulley, which are transmitted to the driving shaft through a reducer. The split gear installed on the driving shaft engages with the large gear ring fixed on the machine body and works in opposite directions. The material is added from the feeding end and passes through the inside of the cylinder. Through the special structure inside the cylinder, it is made into particles and finally flows out through the discharge port. Due to the continuous entry of materials and the continuous rotation of the granulator, mass production can be achieved.

The drum granulator is equipped with steam, gas ammonia, or the addition of phosphoric acid or nitrogen solution, phosphorus ammonia slurry, and heavy calcium slurry to complete the chemical reaction and heating process of compound fertilizer granulation in the cylinder; Alternatively, in the cold granulation process of adding a small amount of water to the compound fertilizer, the materials that need to be granulated are moved through the cylinder, causing rolling and rotation when there is no material in the cylinder, and then agglomerated into balls under appropriate humidity and temperature to complete the granulation process.

Characteristics of drum granulator:

1. The ball forming rate reaches 70%, with a small amount of returned material, which has a small particle size and can be re granulated;

2. Inject steam for heating, increase the temperature of the material, reduce the moisture content of the material after balling, and improve the drying efficiency;

3. Using rubber engineering plastic as the inner lining, the raw material is not easy to stick to the cylinder and plays a role in anti-corrosion and insulation;

4. Large production capacity, low power consumption, and low maintenance costs.

How to use organic fertilizer production lines to treat animal manure from farms?

fertilizer granulator Sep 18, 2023

How to deal with animal manure from large farms? One adult sheep can produce about 1.5kg of manure per day, 10,000 sheep can produce 15,000 tons of manure per day, and the annual output is 5,475 tons of sheep manure. This sheep manure can be sold as fertilizer.After 3 tons of sheep manure is dehydrated and fermented, it can be made into 2 tons of sheep manure as an auxiliary material for organic fertilizer. 5,475 tons of organic fertilizer can process about 2,488 tons of organic fertilizer, and can be equipped with a 5,000-ton organic fertilizer production line.

The 5,000-ton organic fertilizer production line can produce powder and granular fertilizers according to market demand. The machines included in the 5,000-ton organic fertilizer production line equipment include fermentation tumbling machine, semi-wet material crusher, mixer, disc granulator machine, screening machine, drum dryer, dryer, coating machine, etc. It can also be matched with a weighing packaging machine for automatic weighing and sealing packaging.

Among them, the fermentation process is very important. Only when the raw material is good, the organic fertilizer can pass the quality test. The following is a general fermentation process. Put pig manure, chicken manure, sheep manure and other agricultural manure into the fermentation tank for composting. In order to reduce the moisture content of the compost material, it is generally chosen to add a large amount of auxiliary materials with low moisture content, such as straw, hull and biogas residues. At this point, it is necessary to use a trench compost turner to mix these auxiliary materials with the manure compost. At the same time, as the decomposition continues, the temperature will continue to rise and the oxygen will continue to fall during the build-up. Therefore, it is necessary to promote oxygen, volatilize excess water, and take away excess heat. A pipe trench composting lathe can solve this problem very well.

After the fermentation is completed, the harmless treatment of manure is basically completed, but in order to improve the quality of crops as an organic fertilizer, crushing, mixing (adding nitrogen, phosphorus, potassium), organic fertilizer granulator machine, etc.
