The production of drum granulator is the process of realizing compound fertilizer hot granulation by compound fertilizer equipment. By increasing the temperature of the material and increasing the solubility of the salt in the granulating water system, the amount of liquid phase meeting the granulation needs of the material under low moisture content is obtained, the heat energy consumption in the drying process is reduced, and the production capacity of the equipment is improved. Therefore, the granulation performance of rotary drum granulator is determined by its advantages and disadvantages The production of compound fertilizer is the key to the yield and quality. How to improve the granulation performance is discussed in this paper.

In the production process of drum granulator, we have encountered two situations due to the different friction between the material and the cylinder wall of granulator.
One is that the material in the npk fertilizer granulator sticks to the wall seriously, the friction between the material in the granulator and the cylinder wall is increased, and the material in the granulator is lifted too high, which causes the material to drop down from the top, and the formed particles are not round and there are too many large particles. We think that there are two reasons for this situation: on the one hand, it is caused by too much sticky material. In this case, we change the process formula On the other hand, the inner part of the granulator is not smooth, which is solved by changing the inner material and increasing the inner smoothness of the granulator.
Second, the internal surface of the granulator is smooth, which reduces the friction between the material and the cylinder wall and weakens the upward movement force of the material. If the material does not roll, it will not produce particles. In view of this situation, we can solve it by adjusting the rotation speed of granulator and installing small-scale plate inside.

The livestock and poultry breeding industry is one of the pillar industries in China’s agricultural development, playing a very important role in increasing agricultural production and income, as well as rural economic development. However, the process of livestock and poultry breeding generates a large amount of waste such as livestock and poultry manure, which not only occupies the site, but also pollutes the environment and spreads pathogens, making it very difficult to handle.

The slot type tipping machine uses a fermentation tank mode to produce organic fertilizer. It is a method of placing raw materials in a fermentation tank, where the materials are flipped, stirred, and crushed, allowing them to undergo fermentation, maturation, and degradation. Compared to static composting, it is easier to achieve stable product performance and better control of odor.

Purpose and characteristics of slot type tipping machine:

1. Suitable for the fermentation and stacking of organic waste such as livestock and poultry manure, sludge waste, sugar factory filtration sludge, slag cake, straw and sawdust. Widely used for fermentation maturation and dehumidification in organic fertilizer plants, compound fertilizer plants, sludge and waste disposal plants, horticultural fields, and mushroom cultivation plants.

2. Suitable for aerobic fermentation, it can be used in conjunction with solar fermentation chambers, fermentation tanks, and transfer trucks. By matching with transfer trucks, it achieves the function of one machine with multiple tanks.

3. High efficiency, stable operation, durability, and even flipping. The walking speed can be adjusted at any time according to the moisture density of the material, completing the operation and throwing speed of the entire tank in one go. It has the function of crushing the material, achieving full contact between the material and air, and improving the fermentation effect of the material.

4. The equipment is equipped with a soft starter during operation, which has a low impact load during startup. The chuck on the mixing shaft is specially designed to fix the mixing knife and is in spiral contact with the material, which can reduce the load on the equipment during the overturning process and improve its service life.

5. The device operation is simple and easy to learn, with just one click operation. Not only can buttons be manually operated, but wireless remote control can also be used for button operation, with a high degree of automation.

6. The slot type tipping machine is equipped with a hydraulic automatic lifting system. During tipping work, when returning to the original position without load or shifting to another fermentation tank, the hydraulic lifting system can be operated at an appropriate height to complete the operation and shifting of the main machine.

7. Equipped with complete limit travel switches for safety and limit operation.

The process principle of the extrusion NPK fertilizer granulator is to make the material into a special shape forming machine. The non drying and normal temperature process is used to produce one-step molding. The whole set of equipment layout is compact and scientific, fertilizer granulator machine price concessions, no waste discharge, stable operation and convenient maintenance. It is suitable for granulation of compound fertilizer, medicine, chemical industry, feed and other raw materials with high granulation rate. It can produce various concentrations and types of compound fertilizer (including organic fertilizer, inorganic fertilizer, biological fertilizer, magnetized fertilizer, etc.). Especially the granulation of rare earth, potash fertilizer and ammonium bicarbonate series compound fertilizer.

Installation of extrusion NPK fertilizer granulator: after the granulator arrives at the plant, take the granulator as the main machine, depending on the number of units, and cooperate with the process flow diagram to find out the elevation and horizontal placement. The machine frame has corner holes, which can be installed on the concrete (the fixed vibration is small, and it does not need a very solid concrete foundation).
The twin roll extrusion granulator uses the motor as the power to connect the belt to drive the two twin roll molds to rotate opposite to each other. Semicircular grooves with the same size are distributed on the mold, and the mold rotates to the contact point to form a circle. The particle size is determined by the selected abrasive tool and formed at one time. It is suitable for organic fertilizer, compound fertilizer, feed, chemical industry and other fields.
Debugging of extrusion NPK fertilizer granulator: the machine has been debugged before leaving the factory, but it still needs debugging after trial. The main steps are as follows: stop the machine, remove the upper frame of the two bearing blocks, adjust the adjusting plate between the two bearing blocks to the required thickness. The two rollers should not collide with each other, and the small size should be kept 3-1 mm.

Making organic fertilizer is a promising project for many people, but they do not have much understanding of this industry, so it takes a long time to investigate before putting it into organic fertilizer production. The investment in organic fertilizer production can be large or small. If you only consider treating livestock and poultry manure from livestock farms, a fermentation equipment is sufficient;

Many small organic fertilizer factories only need fermentation equipment, organic fertilizer crushers, organic fertilizer mixers, organic fertilizer granulators, screening machines, and quantitative packaging scales to put into production. However, this mode of production requires a lot of human operation, such as manual stacking and drying of raw materials in the early fermentation stage and after granulation.

A fully equipped organic fertilizer factory only requires five or six people for the entire organic fertilizer production line, which does not require significant investment in manpower, but needs to be expanded in equipment investment. The investment in organic fertilizer is not only in equipment, but also in site and infrastructure construction. Therefore, the investment in organic fertilizer varies from tens of thousands to hundreds of thousands.

Simple configuration of organic fertilizer equipment includes: fermentation equipment, organic fertilizer crusher, horizontal mixer, organic fertilizer granulator, drum screening machine, and quantitative packaging scale. These five equipment can put organic fertilizer into production.

If it is necessary to reduce labor costs, several belt conveyors can be added. In this equipment, manual flipping during organic fertilizer fermentation and drying after organic fertilizer granulation are required.

This simple configuration of organic fertilizer equipment is suitable for use in small organic fertilizer processing plants or breeding farms. Under the premise of small equipment cost investment, it can ensure the normal operation of organic fertilizer production.

The rotary drum granulator has the advantages of advanced function, reasonable design, low energy consumption, high efficiency, convenient maintenance and operation, and has been officially determine. The fertilizer granulator machine price is cheap. However, in the current granulator market, the quality is mixed, and fake and shoddy products emerge in endlessly. How can we distinguish the true from the false of the rotary drum granulator? Please see the introduction below.

1. There is no factory name, no factory address and no product certificate for the “three noes” products of the rotary drum organic fertilizer granulator. Because most sawdust granulator manufacturers are small individual enterprises, some of them even small workshops, such as husband and wife shop, mother and son shop and father and son shop. They are all produced irregularly according to the farming season, and they are not registered in the industrial and commercial department. As a result, they can’t see any basic product information, such as trademark, factory name and factory address, on their sawdust choppers.
2. False propaganda, the production ability, matching ability, operation function, scope of application and service life and other indicators indicated in the manual of rotary drum organic fertilizer granulator machine are inconsistent with the actual situation.
3. The material of drum granulator does not meet the requirements. Use waste oil bucket and paint bucket instead of design material. In the shaping process, these wastes often lead to stress concentration, local cracking and internal damage.

The organic fertilizer chicken manure production line is currently an important component of the equipment required for the production of organic fertilizer in the fertilizer industry. After being treated and processed by the equipment, organic waste can be turned into treasure to increase economic benefits and solve environmental pollution problems, corresponding to national environmental protection policies; The organic fertilizer produced by the organic fertilizer production line also plays a decisive role in the cultivation of organic crops and organic fruits and vegetables. All have received recognition and high praise from the vast number of users.

Small powder chicken manure organic fertilizer production lines generally choose small mixers, shallow slot stackers, or stacked stackers, refining equipment, automatic packaging machines, etc. The pre mixing equipment for large-scale powdery organic fertilizer production lines generally selects double spiral mixers or unpowered mixing mixers, and the selection of a shallow groove or spiral or chain plate type stacker is generally determined based on one’s own financial situation and level of automation. To refine the equipment, it is necessary to choose 2-3 large pulverizers, or choose screening and crushing first to save some energy. This is because the fermented organic raw materials have high moisture content, high difficulty in crushing, and high power of the equipment. In order to achieve high yield, high efficiency, and energy conservation, screening and refining equipment must be selected. After packaging, it is necessary to choose an organic fertilizer powder packaging machine for this packaging.

The small-scale powdery chicken manure organic fertilizer production line is designed for users who are just starting out and lack funds. We consider that users are worried about the high price of powdery organic fertilizer equipment because they have just started building factories, but their own farm manure has no place to treat, pollutes the environment, and has a foul odor for several miles. Therefore, our company has designed a small-scale powdery chicken manure organic fertilizer production line, which can solve the problem of low investment and fast return efficiency, There is no need to worry about sales issues (self use or local sales). The small-scale chicken manure organic fertilizer powder production line costs around 80000 to 100000 yuan, and low-cost investment not only solves environmental pollution problems but also increases income, making it a good project to become rich.

More and more farm waste is being utilized through organic fertilizer equipment to achieve waste utilization and turn waste into treasure. In the production process of organic fertilizer, the fermentation process can be completed using various types of organic fertilizer fermentation equipment, such as fermentation tanks and flip throwing machines. The tipping machine is further divided into slot type tipping machines, forklift tipping machines, tracked tipping machines, and so on, each with its own characteristics. Among them, the track type tipping machine is the one that saves civil engineering and human resources more.

The track type tipping machine adopts a four wheel walking design, which can move forward, reverse, and turn, and is driven by one person. During driving, the entire vehicle rides on a pre stacked long strip pile, and the raw materials of the pile are mixed, fluffy, and moved by the rotating blade shaft under the frame. After passing by, the vehicle is tampered with into new strip piles. Operations can be carried out in open spaces or in workshop greenhouses. The outstanding technology of this machine lies in the integration of the crushing function in the later stage of material fermentation. With the gradual dehydration of materials and the installation of crushers, the efficiency of crushing has been greatly improved, costs have been reduced, and the problem of production volume being restricted by crushers has been fundamentally solved. Compared with other types of machines such as “tipping machines,” “mixers,” and “spiral stirring machines,” the stacker has significant characteristics:

1. Specially designed for the process requirements of microbial aerobic fermentation materials, it can effectively mix viscous fermentation materials, microbial fermentation agents, and straw powder. Under this loose material property, fermented materials can be heated up within 45 hours, deodorized in a short period of time, and fertilized in about 12 days. Not only does it have a much faster fermentation speed than deep tank fermentation, but it also effectively prevents the generation of harmful and odorous gases such as hydrogen sulfide, amine gas, and indole during the fermentation process, meeting environmental requirements and producing better organic fertilizers.

2. The overall structure is reasonable, with good rigidity, balanced force, simplicity, safe and reliable performance, easy operation, and strong adaptability to the site. It is composed of a sturdy frame and national standard components, making it easy to use and maintain.

The production process of compound NPK fertilizer is mainly composed of raw material proportioning, mixing, crushing, drum granulator, primary screening, particle drying, cooling, secondary screening, particle coating and packaging. Granulation is an important link, which is generally realized by roller extrusion granulator, disc granulator or drum granulator. The fertilizer granulator machine price varies according to specifications and types.
In several kinds of compound NPK fertilizer granulation process, drum granulation production process is favored by many compound fertilizer manufacturers and adopted by more and more compound fertilizer manufacturers for its advantages of relatively small formula limit, high output, low investment and short construction period.

In the actual production of drum granulation process, in order to fix the steam pipe, water pipe, liquid ammonia pipe, dilute sulfuric acid pipe and their respective reactors and other equipment, manufacturers usually set a central installation pipe through the drum granulator. However, due to the existence of the central installation pipe, during the operation of the NPK fertilizer granulator, the wet materials will be thrown up and down on the central installation pipe with the rotation of the rotating drum, resulting in the material sticking and forming large pieces of material, which makes the granulation effect significantly worse, the product particle size is uneven, the finished product quantity is reduced and the output is reduced.

The organic fertilizer granulation equipment drum granulator is a molding machine that can manufacture materials into specific shapes. The cylinder is lined with special rubber plates or acid resistant stainless steel plates, achieving automatic scar removal and tumor removal, eliminating traditional devices. A drum type granulator, in which steam, gas ammonia, or phosphoric acid or nitrogen solution, phosphorus ammonia slurry, and heavy calcium slurry are introduced 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 working principle of the organic fertilizer drum granulator: The rotating components of the traditional horizontal centrifuge are separated into two parts: the inner and outer shaft systems that rotate synchronously. The outer shaft system is fixed axially, and the inner shaft system can move axially under the action of the synchronous rotating oil cylinder. The filter cloth is bag shaped, with one end fixed to the large end of the drum on the outer axis and the other end fixed to the small end of the push plate on the inner axis. During separation, under the action of centrifugal force, the filtrate passes through the filter cloth and drum, and the solid is intercepted by the filter cloth and forms a filter cake; When unloading, under the action of synchronous rotating oil cylinder, the inner shaft system is pushed out along the axial direction and drives the filter bag to flip, while completing the operation of filter cake unloading and filter cloth regeneration.

The granulation process of organic fertilizer granulation equipment is: 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 body, working 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 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.

Recently, the investment project to open an organic fertilizer processing plant has become a popular project, as organic fertilizer can be said to be a marketable product with policy subsidies and support. Many people want to open a small organic fertilizer processing plant, although it is a small organic fertilizer plant, its profitability is not small, and it is also a block in the current cycle. But having a cavity full of enthusiasm is not enough. Let’s take a look at what aspects need to be considered when building an organic fertilizer plant together?

1. Selection of raw materials for organic fertilizer production

There are many raw materials that can produce organic fertilizers, such as cow, sheep, pig and other livestock manure, urban sludge, animal and plant residues, straw, etc. Due to the difficulty in transportation of these raw materials, it is necessary to first determine them based on the principle of proximity. It is also possible to build factories around rich raw materials, which is the first step to consider and a top priority.

2. Production scale and annual output planning

Firstly, determine the expected production scale based on one’s own investment budget. If the investment scope is not limited, conduct in-depth investigation and research from the supply of surrounding raw materials, market demand, and other aspects to determine the expected production scale.

3. Selection of production site

Firstly, considering the cost of land use, choose regions with high cost-effectiveness. Then choose an area with complete water and electricity supply and convenient transportation. Next, choose the area with sparse surrounding residents and closest to the raw materials. You can look for it near the local farm.

4. Determine the process flow for organic fertilizer production

The determination of production process is very important, for example, there is a significant difference between powdered organic fertilizer and granular organic fertilizer. Not only do the finished products have different shapes, but also the production equipment required is different. It needs to be carefully studied and decided based on the surrounding market.

5. Plant construction planning

Visit and learn from large organic fertilizer manufacturers, or inquire with organic fertilizer equipment manufacturers, consider multiple factors, make reasonable plans for organic fertilizer factories, and finalize plans.
