fertilizer production line

Plant ash is used to manufacture fertilizer processing equipment. The residual ash from the burning of plant stems and leaves is called plant ash. In rural areas, wheat straw, soybean straw, corn straw, rice straw, tree branches, fallen leaves, and other fuels are commonly used. Therefore, plant ash is an important fertilizer resource in rural areas. Grass ash contains various ash elements in plants, such as phosphorus, potassium, calcium, magnesium, and various trace elements. Among them, potassium and calcium are abundant and are generally regarded as potassium fertilizers.

The process of compound fertilizer production equipment consists of multiple processes: raw material measurement, raw material crushing, granulation, drying, cooling, screening, coating, and packaging. The production line has always adhered to the principles of “liquidity, safety, operability, and aesthetics” in the design, so that the whole production line can achieve electromechanical integration, and it will be quite advanced in the future for a certain period of time. At the same time, we can also adjust the process flow according to specific circumstances and requirements.

The compound fertilizer production equipment is completed by a close combination of multiple processes. Each process has strict indicator control, and none is indispensable. Firstly, technical personnel develop corresponding fertilizer production formulas based on market needs or customer needs, combined with the market situation of raw materials, and refine them into the input amount of raw materials.

Circular economy is the current trend of environmental protection and sustainable development in China. It is an advanced development model that can resolve the long-standing sharp conflict between environment and development. Building a circular economy is an inevitable choice and important guarantee for implementing sustainable development strategies. And organic fertilizer equipment has a long way to go to completely solve the source of pollution.

The configuration of small pig manure organic fertilizer equipment only needs a pulverizer, a mixer, a granulator, a screening machine and a packaging machine to complete the production. The configuration of small organic fertilizer equipment belongs to the middle and low configuration, and the quality of organic fertilizer equipment configuration directly affects the level of benefits. Therefore, when we choose small organic fertilizer equipment, we must choose a good small organic fertilizer production line configuration. Next, let us understand together how to choose a granulator.

Granulation process: The organic fertilizer granulator adopts high-speed rotation, and the material is turned over at a high speed with the barrel, so that the powder adheres under high-speed movement, and the processes of mixing, granulation, spheroidization, and densification are continuously realized internally, so as to achieve the goal of granulation purpose.

Determine the shape of the fertilizer: determine the shape of the granules, that is, what kind of granulator to choose: powder, column, oblate or standard round. Commonly used granulating organic fertilizer equipment are: disc granulator machine, npk fertilizer granulator, drum granulator, wet granulator, roller extrusion granulator, flat die granulator. The selection of the granulator should be determined according to the local fertilizer sales market. The shape of the granules is different, the process of the organic fertilizer equipment is also different, and the fertilizer granulator machine price is also different.

For example, the disc granulator is powered by a motor to drive the inclined disc to rotate. The internal scraper prevents the material from sticking to the bottom of the disc. When the material rotates to the top, it rolls down by itself, and rolls into particles like a snowball. Suitable for non-sticky powdery materials.

The counter-roll extrusion granulator uses the motor as the power to connect the belt, and drives the two counter-roll dies to rotate toward each other. The semi-circular grooves of the same size are distributed on the die, and the die rotates to the contact point to form a circle. The resulting particle size is determined by the abrasive tool selected and is formed in one pass. It is suitable for organic fertilizer, compound fertilizer, feed, chemical industry and other fields.

The organic fertilizer production equipment processes livestock and poultry manure into organic fertilizer, requiring small forklifts for material transfer and stacking. The tipping machine is used to flip and mix strip piles for cooling, crushing, oxygen intake, evaporation of water, and uniform bacterial species, promoting the acceleration of manure maturation, biological bacterial growth, and shortening the fermentation cycle of livestock and poultry manure. The shredder is used to treat decomposed feces in blocks.

Commonly used organic fertilizer granulator equipment are: disc granulator machine, drum granulator, wet granulator, drum extrusion granulator, flat die granulator, and tooth stirring granulator. The choice of granulator should be determined according to the local organic fertilizer sales market. If the shape requirements of the granules are different, the processing process of the organic fertilizer production line is also different, and the price of the organic fertilizer production line is also different. Choose the appropriate organic fertilizer granulator according to the specific process requirements. There are many types of granulators. The specific use is very different. Let’s learn about the drum granulator.

The organic fertilizer rotary drum granulator has no sticking phenomenon, which is conducive to the classification of dry and wet particles, and the relative granulation ratio is low, generally 40% -60%. Therefore, the reaction rate is high, but the requirements for the mixing and degree of material mixing in the mixing process are relatively low.

The new organic fertilizer granulator has a wide range of applications, especially for the granulation of light and fine powders. The finer the basic particles of the fine powder material, the higher the degree of sphericity of the particles, and the better the quality of the particles. In general, the particle size of the material before granulation must be less than 200 mesh. Typical application materials are chicken manure, pig manure, cow manure, charcoal, clay, kaolin, etc. Due to the particularity of raw materials such as livestock and poultry manure, organic fertilizer, degummed fertilizer, green manure, sea manure, cake fertilizer, peat, soil fertilizer, three wastes, microorganisms and other municipal solid waste granulation, the particles are irregular.

The compound fertilizer rotary 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 rotated through the cylinder, causing rolling rotation when there is no material in the cylinder, and then agglomerated into balls at a certain humidity and temperature to complete the granulation process.

The composite fertilizer drum granulator adopts a special rubber plate lining or acid resistant stainless steel lining plate to achieve automatic scar removal and tumor removal, replacing the traditional scraper device. This machine has the characteristics of high ball forming strength, good appearance quality, corrosion resistance, wear resistance, low energy consumption, long service life, and convenient operation and maintenance. Steam and gas ammonia are introduced into the drum granulator, or phosphoric acid, nitrogen solution, phosphorus ammonia slurry or heavy calcium slurry are added to complete the chemical reaction and heating process of compound fertilizer granulation in the cylinder; Alternatively, a cold granulation process for adding a small amount of water to the compound fertilizer. The material that needs to be granulated is rotated through the cylinder, causing rolling rotation when there is no material in the cylinder, and then agglomerates into a ball under a certain humidity to complete the ball making process.

The main advantage of the compound fertilizer drum granulator is that it uses steam heating to regulate humidity, increases the temperature of the granulation material itself, reduces granulation water content, reduces the load of the dryer, and improves work efficiency. The granulation rate can reach 70% using a drum granulator, and the equipment is easy to operate, with high work flexibility and convenient maintenance. The equipment is lined with ultra-high molecular weight polyethylene (UHMW-PE), which eliminates the phenomenon of material sticking to the wall, reduces the labor intensity of workers, and greatly extends the service life of the equipment.

The working principle of the rotary drum drying equipment for manure production organic fertilizer:

When the bottom temperature of the organic fertilizer rotary drying equipment in the production of bacterial residue reaches 400 ℃ -800 ℃, the material is fed into the feeding port by the elevator, and under the action of gravity, it is dispersed, crushed, and the dispersion device is uniformly distributed inside the dryer to flow (ensuring the heat exchange effect of the material inside the dryer). Hot gas is generated by the lower hot air furnace and moves from bottom to top, coming into contact with the material. Through various means such as heat conduction, convection, and radiation, heat is transferred to the material, causing the temperature of the material to continuously rise and the moisture to evaporate. Materials that meet the moisture requirements are discharged from the lower outlet, and gas with water vapor is extracted by the fan from the chimney.
