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.

Perhaps the most troublesome issue for farmers in recent years is the treatment of livestock and poultry manure. If it is not piled up, the environmental protection department should come to their doorstep. I want to sell it but I don’t know who to sell it to. Nowadays, farmers are unwilling to use chicken manure for fertilization. Firstly, it’s too smelly, and secondly, it’s too troublesome. To produce organic fertilizers on a large scale, the raw materials are indeed insufficient. It is recommended that these small farms purchase an organic fertilizer fermentation equipment to simply ferment livestock and poultry manure, which greatly reduces the odor and meets the environmental protection requirements of the environmental protection department. Moreover, the fermented livestock and poultry manure is easier to store and transport, and can be sold to nearby farmers or large fertilizer factories for further processing.

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.

Process and advantages of sheep manure organic fertilizer equipment production line

fertilizer granulator Sep 18, 2023

The sheep manure processing organic fertilizer production line is a processing equipment that uses sheep manure to produce organic fertilizer. The sheep manure processing organic fertilizer production line is mainly suitable for the harmless utilization of sheep manure, achieving resource recycling and recycling. The fertilizer produced by the sheep manure organic fertilizer production line belongs to green organic fertilizer, with an organic matter content of over 50%, which is a nutrient rich organic fertilizer. In practical application, organic fertilizer equipment manufacturers generally require reasonable mixing and use of trace elements based on soil conditions in various regions. This will result in the formation of specialized organic fertilizers for crops such as different vegetables and fruit trees with different needs.

The production equipment for sheep manure organic fertilizer material ferments, matures, and dries until the organic waste with a water content of about 30 is crushed. After magnetic separation and screening, it is measured, batched, and mixed (or further dried to produce powdered organic fertilizer) in an automated batching and mixing system according to the ratio requirements, along with the raw materials of binders and other components that need to be compatible. The fully mixed material is uniformly and continuously fed into a granulator by a belt conveyor for granulation, Then, it is dried by a dryer with low temperature and high air volume, followed by cooling, screening, and the finished particles are coated by a coating machine (with brightener and anti caking agent added).

The production equipment for sheep manure organic fertilizer material is transported by a belt conveyor to the finished product silo, measured by a computer automatic quantitative packaging system. The finished products packaged in 40-50kg/bag are stacked and stored, and finally circular particles of fertilizer are produced. The material transportation between various equipment in the entire production process is configured according to the equipment configuration requirements.

The production line of sheep manure organic fertilizer equipment has low energy consumption, small footprint, no odor in the operating environment, zero pollution, good ventilation, and deodorization in only 1-2 days. The small-scale organic fertilizer production line has a compact structure and advanced technology. It uses harmless live bacterial preparations to treat livestock and poultry manure, and undergoes biological fermentation under the action of various beneficial microorganisms. After fully decomposing the organic matter, nutrients are released, and the resulting biological heat and high-temperature fermentation process can kill bacteria and insect eggs, detoxify and deodorize, purify the environment, and achieve harmless, resourceful, and industrialized treatment. The energy consumption is low, and the product quality is stable.

The working principle and characteristics of pig manure organic fertilizer granulator

fertilizer granulator Sep 18, 2023

Pig manure, which is dirty and smelly, is a large amount of feces excreted by pigs during the process of raising pigs. It is a coarse fibrous substance mixed with a large amount of urine and mucus. Pig manure is a type of livestock manure that is not easy to air dry. With the continuous expansion of aquaculture scale in China, intensive farming has brought about the concentration of a large amount of pig manure, which is difficult to handle when piled together. Long term storage not only attracts mosquitoes and flies, but also causes great pollution to the surrounding environment and underground water sources due to the odor. If the problem of pig manure is not solved environmentally, it not only causes increasingly serious environmental pollution, but also has a serious impact on the sustainable development of breeding farms. How to effectively treat and develop pig manure has become a top priority issue for the sustainable development of pig farms.

Practice has proven that using animal manure to produce organic fertilizer is a relatively effective method for large-scale pig farms to design manure free organic fertilizer production lines and workshops, and provide complete sets of pig manure organic fertilizer equipment. Releasing nutrients can kill bacteria and insect eggs, detoxify and deodorize, achieving harmless and resource utilization. The commercial organic fertilizer production line can not only meet the local fertilizer demand, but also meet the demand of surrounding markets.

The working principle of pig manure organic fertilizer granulator: Various dry powder materials are added from the top of the equipment, degassed, spiral pre compressed, and transported to the curved grooves of two rollers. The two rollers rotate at equal speed and in reverse direction, biting the materials into the grooves and performing forced compression. The pressure that the materials bear gradually decreases after passing through the compression zone, and its surface tension and gravity cause them to naturally come out, enter the crusher and the whole granulator for crushing and trimming, Then it enters the vibrating screen for screening, and the qualified products are sent to the finished product warehouse or directly packaged through a conveyor. The materials under the powder screen are sent back to the raw material warehouse for secondary rolling through a feeding device. The size of the squeezing force can be adjusted by the hydraulic system according to the particle strength needs. By changing the groove form of the roller surface, materials such as flakes, strips, olives, and flat balls can be obtained.

Why do farms choose organic fertilizer equipment to produce fertilizers?

fertilizer granulator Sep 18, 2023

As we all know, as a traditional fertilizer, organic fertilizer has unparalleled advantages in improving soil. Although chemical fertilizers still occupy most of the market, the overall trend is declining, gradually giving way to organic fertilizer products. Most of the commercial raw materials of organic fertilizer come from livestock and poultry manure, which is a traditional fertilizer used in the planting industry. In particular, trace elements or biological strains are added in the industrial production process, which further improves the effect of fertilizers.

When it comes to livestock and poultry manure, the first thing that comes to our mind is the continuous discharge of odor and wastewater, which has nothing to do with the finished organic fertilizer equipment sold on the market, which also determines that the production of organic fertilizer equipment is a complex process. The fermentation cycle time of the first process is very long, which requires the cooperation of bacteria and stackers to gradually kill harmful microorganisms in the raw materials, volatilize excess water, and finally become a harmless organic fertilizer raw material without peculiar smell.

After manure fermentation, if the production of granular organic fertilizer requires granulation, drying, etc., a complete set of organic fertilizer production line equipment includes: fermentation turner, crusher, feeder, horizontal mixer, organic fertilizer granulator, dryer , cooling machine, screening machine, weighing packaging machine. Common organic fertilizer granulators on the market include: roller extrusion granulator, npk fertilizer 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.
