Pig manure large-scale organic fertilizer production line can produce 100,000-200,000 tons of organic fertilizer per year, supporting dehydrator, fermentation stacker, pulverizer, screening machine, mixing mixer, disc granulator machine, dryer, cooler, screening machine , packaging machines, forklifts, etc. The fertilizer granulator machine price, including various equipment, varies. About a complete set of large-scale organic fertilizer production line equipment is purchased at a price of nearly one million yuan, and the investment cost is high. Therefore, the damage and maintenance of organic fertilizer equipment will not only increase the depreciation cost, but also affect the entire organic fertilizer production. Production efficiency, how to reduce the failure rate of organic fertilizer equipment and prolong the use efficiency of organic fertilizer equipment, what should be done?

1. First of all, do basic maintenance and management work, and operate according to the equipment operation instructions to ensure the basic service life of the equipment and reduce the failure rate. In the process of using organic fertilizer fermentation equipment, the usual maintenance is very important. Therefore, when a small fault occurs, it should be dealt with in time. If it is not discovered and solved in time, it will gradually increase in the later period, resulting in serious failures, which require more maintenance costs to solve.

2. When operating organic fertilizer equipment for fermentation, it should be used correctly. If the long-term use is not standardized, it is easy to cause the failure of organic fertilizer equipment. If the fermentation time is insufficient, causing harmful objects to erode the machinery, it should be avoided as much as possible, and the equipment usage specifications should be strictly followed.

3. Organic fertilizer equipment has a certain service life in the process of use and follows the rules. Therefore, when the organic fertilizer equipment reaches a certain service life, long-term high-load operation should be avoided as much as possible.

Processing Equipment and Technology of Rapeseed Cake Fertilizer Production Line

fertilizer granulator Sep 26, 2023

Many people are probably familiar with rapeseed cake. In fact, about 60% of the residue after rapeseed cake oil is pressed remains. Due to the large amount of protein in rapeseed cake, it can become one of the raw materials for organic fertilizer fermentation.

The rapeseed cake fertilizer production line uses decomposed rapeseed cake, soybean residue, and other organic fertilizers to not only fertilize the soil, enhance soil permeability, alleviate soil compaction, prevent root burning, but also inhibit pathogenic bacteria in the soil. Reduce the occurrence of soil borne diseases, but if rapeseed cakes, bean dregs, and other materials do not mature, they not only cannot fully exert their effects, but also are not conducive to the growth of vegetables, flowers, and fruits.

The production process of organic fertilizer production equipment mainly involves mixing organic solid waste with a moisture content of less than 60%, such as chicken manure, pig manure, cow manure, duck manure, household waste, sugar residue, distiller’s grains, sludge, drug residue, sugar residue, mushroom waste, rice husk, weeds, straw, monosodium glutamate plant waste, etc., as the main raw materials. Microbial fermentation agents are added to mix well, and aerobic continuous fermentation is carried out to fully decompose, sterilize, deodorize, and remove water, After fermentation, decomposition, drying, and crushing of organic waste with a moisture content of 30-35%, magnetic separation and screening are carried out. Then, the raw materials with binders and other components that need to be compatible are measured, batched, and mixed (or further dried to produce powdered organic fertilizer) in an automated batching and mixing system according to the ratio requirements. The fully mixed materials are 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 (≤ 65 ℃) before cooling and screening. The finished particles are coated by a coating machine (with brightener and anti caking agent added), transported by a belt conveyor to the finished product silo, and measured by a computer automatic quantitative packaging system. The finished products packaged in 40-50kg/bag are then stacked and stored.

The rapeseed cake fertilizer processing production line includes fermentation equipment, granulation equipment, crushing equipment, mixing equipment, screening equipment, cooling equipment, drying equipment, coating equipment, automatic packaging equipment, and other technological processes.

Which heat source is the best choice for chicken manure dryer

fertilizer granulator Sep 26, 2023

The chicken manure dryer operates at high temperatures and relies on heat sources for transmission. However, there are also various options for heat sources, such as natural gas, diesel, coal, and so on. So, which heat source is better for Tongda Heavy Industry chicken manure dryer?

Chicken manure dryers often use coal and natural gas as heat sources, which play an important role in production. Coal has the characteristics of low cost and high heat, playing an important role in dryers; Natural gas has the advantages of high heat, stability, and no smoke pollution. So how should we choose between the two heat sources?

What heat source is used for the chicken manure dryer? Which heat source is the best choice for chicken manure dryer?

Coal is one of the earliest discovered minerals by humans and is currently a widely used heat source material. The national requirement is that the heat of standard coal is 7000 kcal/kg. Currently, the price of normal coal is around 1200 yuan, and the price of one kilogram of coal is about 1.2 yuan.

Natural gas is a multi-component mixed gaseous fossil fuel, mainly composed of alkanes, with methane accounting for the majority and a small amount of ethane, propane, and butane. At present, the price of natural gas may vary depending on the region, but it remains at 2.5 yuan/cubic meter, while the calorific value of natural gas is 8000 kcal/cubic meter.

The above heat sources are for users to choose from, and which one to choose depends on local needs. The water vapor, powder, and odor gas generated during the re drying process of the chicken manure dryer are discharged into the dust removal system and deodorization system through the fan through the pipeline, and then discharged into the air. Chicken manure is sterilized, disinfected, and deodorized by high-temperature airflow in the drum, which turns it into high-quality and efficient organic fertilizer or feed.

The granulation process of cow manure organic fertilizer increases profits from fertilizer processing

fertilizer granulator Sep 26, 2023

After cow dung is made into fertilizer, it is beneficial to improve soil organic matter and fertility, and improve soil physical and chemical environment and microbial environment. However, if the uncomposted manure is directly applied to the farmland, it will consume oxygen in the soil, generate high temperature, burn the root system of crops, and produce harmful substances of pathogenic bacteria, which will not only fail to increase production, but also cause secondary pollution of soil, water, atmosphere and agricultural products. Therefore, cow dung can only be used after being composted, decomposed, stabilized, and harmless. Then organic fertilizer equipment is needed to convert cow dung into organic fertilizer with higher utilization value.

Organic fertilizer production line or npk manufacturing process, the main equipment of general processing technology includes fermentation equipment, mixer, overturning equipment, belt conveying equipment, cylindrical screen, pulverizer, granulator, drying cooler, packaging machine, etc. Common granulators include counter-roll granulators, spinning granulators, tooth stirring granulators, disc granulators, etc. The fertilizer granulator machine price vary.

The production process of organic fertilizer granulator: First, the cow dung should be dried to make its moisture content below 85%, and then the straw is added. The carbon ratio is controlled at 23-28, and the water content is controlled at 52%-68%. Finally, add organic fertilizer fermentation decomposing agent. Pour the raw materials into the mixer to mix, mix evenly, pulverize, and use the belt to enter the disc granulator; after the granulation is formed, it is sent to the dryer for drying, and then cooled to the cooler by the elevator or belt conveyor. When the moisture reaches below 6%, it is sieved after cooling. The large particle materials are crushed into fine materials by the return pulverizer, the fine materials enter the disc granulator machine, and the coarse return materials are crushed into the granulator, and the finished products are directly packaged.

The working principle and structure of a nitrogen phosphorus potassium horizontal mixer

fertilizer granulator Sep 26, 2023

The horizontal mixer of nitrogen, phosphorus, and potassium ensures sufficient mixing of materials, thereby improving the uniformity of mixing; Adopting a novel rotor structure, the minimum gap between the rotor and the bright body can be adjusted to close to zero, effectively reducing material residue; It can crush larger materials, with a more reasonable overall structure and beautiful appearance. It is generally used for mixing organic fertilizers, bio organic fertilizers, feed and other raw materials. It is also particularly suitable for mixing viscous materials.

Principle and structure of nitrogen phosphorus potassium horizontal mixer:

In terms of agitator structure, the spiral is designed as an inner and outer, left and right opposite spiral to each other.

The inner spiral drives the material near the axis to rotate axially, pushing it from the inside to both sides. The outer spiral drives the material near the barrel wall to rotate axially, pushing it from both sides to the inside, causing convection, circulation, shear, and infiltration of the material inside the barrel, achieving rapid and uniform mixing of the material in a short period of time.

The working principle of a horizontal mixer: The horizontal cylinder is equipped with double axis rotating blades that rotate in opposite directions. The blades rotate and stir the material at a certain angle along the axial and radial directions, making it quickly and evenly mixed. The performance characteristics of the horizontal mixer are that the rotation speed of the shaft driven by the reducer and the structure of the blades will weaken the gravity of the material. With the lack of gravity, there are significant differences in particle size and specific gravity among the materials, which are ignored during the mixing process. The intense stirring movement shortens the mixing time, making it faster and more efficient. Even if there are differences in the specific gravity and particle size of the materials, good mixing results can be achieved under the rapid and violent flipping and scattering of staggered mixing blades. High mixing uniformity and low residue, suitable for mixing two or more types of fertilizers and additive premixes.

Installation and maintenance of nitrogen phosphorus potassium horizontal mixer: The maintenance and upkeep of the machine is an important and regular task, which should be closely coordinated with extreme operations and maintenance, and should be inspected by dedicated personnel on duty. In addition to normal fertilizer production models, our factory can customize production according to customer requirements.

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.
