Organic fertilizer granulator machine is divided into drum granulator, agitator granulator, flat die granulator, extrusion granulator, disc granulator, etc. Although the working principles are different, the daily maintenance methods are basically the same. As for the equipment that is really damaged, we need to find professional personnel to repair it. The purpose of daily maintenance of organic fertilizer granulator is to reduce and avoid equipment damage Bad and affect the production of organic fertilizer, resulting in economic losses. So how to maintain the organic fertilizer granulator in daily use?

Maintenance method of organic fertilizer granulator machine:
1. Keep the working site clean. After each test of organic fertilizer equipment, thoroughly remove the residual rubber sand inside and outside the granulator, clean up the scattered or splashed glue sand and flying objects on the organic fertilizer equipment, wipe the exposed processing surface of the organic fertilizer equipment machine, apply anti rust meat paint and cover with corresponding shield to prevent dust from invading again.
2. If the organic fertilizer granulator machine can not operate, check whether the power supply voltage, power plug socket and connecting plug socket are normal, and check the internal fault of the controller.
3. Always pay attention to the operation of organic fertilizer granulator machine, there should be no serious abnormal noise and dry sound, and there should be no metal friction sound. If abnormal, it should be stopped immediately and checked. After troubleshooting, it can be used. If the corresponding reason is not found, the machine can not be started. If there is metal friction sound, the clearance between organic fertilizer equipment can be checked first.
4. Check the standard clearance between organic fertilizer granulators frequently.
5. When the organic fertilizer granulator is overhauled, the working clearance should be re measured each time and adjusted many times, and it can be continued to use after meeting the standard.

Organic fertilizer dryers play an important role in the production of organic fertilizer production lines, but in the process of use, there will inevitably be some failures. This article will introduce some common organic fertilizer dryer failures and troubleshooting methods to help you better maintain and use the dryer.
A section of secondary granulation area is set at the front of the organic fertilizer dryer, in which the materials can realize secondary granulation. Then the materials are lifted up through the lifting plate and fully dried. The wet hot air is extracted from the tail of the dryer through the exhaust fan through the pipeline and enters the sedimentation chamber for sedimentation. The tail gas is sprayed to reduce dust through the washing tower after sedimentation. The spray water is pumped out by the water pump for recycling. After secondary dust reduction treatment, the tail gas is discharged into the atmosphere through the chimney.
First, the Organic fertilizer dryers does not work

5. Abnormal heating of the dryer
Fault cause: the heat dissipation system of the dryer is faulty.

The vertical chain crusher for organic fertilizer is one of the commonly used crushers in the compound fertilizer industry. During the crushing process, it uses high-strength wear-resistant hard alloy chains with synchronous speed, which is suitable for crushing raw materials and return materials. Especially for materials with high moisture content, they have strong adaptability and should not be blocked. The material is discharged smoothly. The material enters from the feeding port and collides with the high-speed rotating chain inside the casing. After the impact, the material is squeezed and crushed, and then collides with the inner wall of the casing before colliding with the chain again. During the falling process, it undergoes several impacts and turns into powder or particles below 3mm, which are discharged from the bottom.

The motor of the organic fertilizer crusher drives the spindle to rotate. The spindle has two bearing seats, upper and lower, which are installed at the upper and lower ends of the casing. The casing assembly is installed on the lower frame, with a rotor disc and chain installed on the main shaft. The feeding hopper is located on the upper part of the casing. In order to facilitate the loading and unloading of the hammer head, a flap is opened on the casing for easy disassembly and maintenance.

Characteristics of organic fertilizer crusher:

1. Especially for materials with high water content, it has strong adaptability, is not easy to block, and the feeding is smooth.

2. The crushing blade is made of special material, which is durable.

3. The crusher has high crushing efficiency and is equipped with an observation window. It can be completed in ten minutes by replacing vulnerable parts.

Fertilizer granulator machine price concessions, stable operation, convenient maintenance, quality assurance, the majority of users like!

The investment of small organic fertilizer production line is between 80000 yuan and 120000 yuan. The main equipment of the small-scale organic fertilizer equipment production line includes fermentation tipping machine, pulverizer, granulator, screening machine, automatic weighing and packaging machine, etc. This series of small organic fertilizer production line has not only high cost performance, but also high efficiency, good energy saving and simple operation for workers. 

① NPK fertilizer production line of ammonia acid process makes full use of the dilution heat of concentrated sulfuric acid and the chemical reaction heat between liquid ammonia and sulfuric acid, monoammonium phosphate and other raw materials to raise the granulation material temperature to 75-85 ℃, and reasonably control the pH value of the granulation material to obtain a good pelleting rate.
② The acid mixer is used to dilute the concentrated sulfuric acid with water and directly add it to the fertilizer granulator machine, which makes full use of the dilution heat of concentrated sulfuric acid, further improves the granulation temperature, reduces equipment investment, simplifies the operation process, and configures the use of special tail gas scrubber, which is more energy-saving and emission reducing (taking 100000 tons / year as an example, the power consumption of ammonia acid process equipment is not more than 35kw).
③ The pelletizing rate is about 80%, and the production capacity of the plant is increased by 50 ~ 100%.
④ With the decrease of granulation moisture, the drying energy consumption is reduced, and the dryer capacity is significantly improved (coal consumption is only 10kg / T).
⑤ The granulation ammoniation is uniform, the pelletizing rate is high, the appearance of particles is smooth and round, and the product strength is more than or equal to 25N.
⑥ The NPK fertilizer production line with ammonia acid method has stable equipment operation and good nutrient stability. It can adapt to different kinds of fertilizer production, and the highest nitrogen content can reach 28.
⑦ The special tail gas scrubber is used to wash the granulation tail gas, and the washing absorption efficiency is above 99%, which ensures the standard emission of granulation tail gas. 

A semi wet material crusher is a new type of crusher used for crushing materials with high moisture content. Using high-speed rotating blades to crush fibers, with good particle size, high efficiency and high energy, and strong adaptability to material moisture content, especially for fermented decomposed garbage or other materials with a moisture content ≤ 30% for powder production. The finished product has a particle size of less than 30 mesh, which better meets the required particle size for granulation. Semi wet material crushers are mostly used in the production and processing of organic fertilizers, and have good effects on crushing raw materials such as chicken manure and humic acid sodium

The semi wet material crusher is composed of three pieces, and the equipment can be reliably used, all of which require a sturdy body steel frame. The steel frames of the semi wet material crusher are all welded with high-quality carbon steel plates and channel steel, and have passed strict product qualification certification and specific process requirements to achieve the purpose of use of this machine; The rotor crushing section: The rotor structure of this machine is novel and well-designed, using double-layer blades for crushing. The crushing effect is twice that of other products. The material enters the crushing chamber from the feeding port and is continuously ground by the double-layer blades to meet the granulation requirements. Transmission connection part: The machine adopts flexible belt transmission. It is driven by an electric motor to drive the pulley and belt, which are directly transmitted to the spindle, causing the spindle to rotate at high speed to achieve the crushing effect.

The semi wet material crusher effectively solves the problem of high moisture content in materials. Even if the moisture content is high, the sample is easy to break and will not cause machine blockage. This is because the double crusher is designed without a screen bottom and mesh, so even if the moisture point of the material is large, blockage will not occur. Even on rainy days, normal production can still be carried out. In addition, although the coal crusher does not have a bottom screen, it uses two rotors on top and bottom for crushing, resulting in a more uniform and ultrafine discharge particle size, which can be controlled below 2 millimeters.

There are many kinds of organic fertilizer granulation equipment, from the most traditional disc granulator and drum granulator to the present agitated gear granulator and combined granulator, each update and development is to meet the requirements of new fertilizer development. All kinds of granulators not only have more and more applicability to materials and meet the granulation needs of all kinds of materials, but also have greatly improved particle quality and particle yield.

Disc granulator is a well-known organic fertilizer granulation equipment, simple operation, fertilizer granulator machine price. The powder materials roll along with the bottom of the plate, and the materials adhere to each other to form spherical particles after being stained with water. Its principle is like a snowball, which depends on the viscosity of the material itself to become bigger and bigger. When the particles grow to a certain extent, they will come out of the plate and enter the next process. If they do not meet the requirements of particle diameter, they will stay in the plate and continue to granulation until they meet the requirements.
The drum granulator also uses a similar principle, except that the disc is an open structure, and the rotary drum is a drum, but both of them are based on the principle that the powder materials are continuously bonded with the help of water to form granular fertilizer with appropriate particle size.
In addition, the new type of granulation equipment also has the stirring tooth granulator, it no longer uses the material’s self rolling to produce the granules like the disc and the drum, but relies on the external force to force the material to form the granules, so the production efficiency is higher and the material requirements are relatively low.
The last is the combined granulator, which is the combination of drum granulator and gear granulator. It is very convenient to use as compound fertilizer granulator.

Powdered organic fertilizer refers to fertilizer produced by fermenting organic raw materials in a certain proportion without causing particles. There is a certain difference from traditional composting fermentation. The national standard is 40% organic matter, over 5% total nutrients, and 30% moisture. The equipment is also relatively simple. The equipment for the small-scale organic fertilizer production line for powder mainly consists of three stages of fermentation, namely: pre mixing, flipping, refining, and packaging. The main purpose of fermentation is to decompose large molecular materials of organic raw materials into small molecular materials that can be absorbed and utilized by crops through microbial decomposition. The quality of fermentation also affects the quality and effectiveness of organic fertilizers.

The small-scale cow manure processing organic fertilizer equipment has good quality and good price. The organic fertilizer production line refers to a complete set of equipment that uses animal manure as the main raw material to produce organic fertilizer. The entire set of equipment includes the process of fermentation into organic fertilizer and the process of making organic fertilizer into granules and packaging. Some customers with less investment choose fermentation equipment, crushing equipment, screening equipment, and packaging equipment to form a set of powdered organic fertilizer production lines.

The equipment for the cow manure powder organic fertilizer production line is designed for novice users. We consider that users are worried about the high price of powder organic fertilizer equipment because they have just started building a factory and do not have enough economic funds. However, their own farm manure has no place to treat, pollutes the environment, and there is a foul odor every few miles. Therefore, our company has designed a small set of powder organic fertilizer production line equipment, which can solve the problem of low investment and fast return on efficiency, There is no need to worry about sales issues (self use or local sales). The entire set of powdered organic fertilizer production line costs around 86000 yuan. Low cost investment not only solves environmental pollution problems but also increases income, making it a good project for farmers to get rich.

Organic fertilizer production line is generally equipped with disc granulator and agitator drum granulator. Disc granulator generally needs granulator, but it is popular because of fertilizer granulator machine price concessions and relatively simple process.
The disc granulator is composed of an inclined granulating disc, a driving device, a disc inclination adjusting mechanism, a frame, a feeding pipe, a material liquid sprayer, a scraping plate, etc. Generally, the tilt angle of disc granulator is 35-55 degrees, and the rotation speed is 10-18r / min. The main factors affecting the granulation of disc granulator are disc direct, disc angle, disc edge height, rotating speed, material liquid spraying device, scraper position, etc. The inclination angle of granulator is determined according to the natural angle of repose of wetting powder before granulation. For example, the natural angle of repose of potassium chloride is 36 degrees, that of diammonium phosphate is 31 degrees, and that of heavy calcium is 32 degrees. When the inclination angle is less than the natural angle of repose of the wetted material, the material will adhere to the disc and rotate with the disc. Therefore, it should be determined according to the specific conditions, generally 40-60 degrees, which can be adjusted by the tilt angle adjusting hand wheel of granulator.

The working principle of the agitator drum granulator is the same as that of the new organic fertilizer granulator. Both of them use the high-speed rotary mechanical stirring force and the resulting aerodynamic force to make the fine powder continuously realize the mixing, granulation, spheroidization, densification and other processes in the granulator, so as to achieve the purpose of granulation. The size of particle diameter can be adjusted by the material mixing amount and spindle speed. Generally, the lower the mixing amount is, the higher the speed is, and vice versa.
The pelletizing rate of agitator drum granulator is higher, and the pelletizing rate is more than 95%. If the output is small, it can be dried after pelletizing to avoid the drying process.
The new type organic fertilizer granulator machine is spherical in shape, sphericity ≥ 0.7, particle size generally between 0.3-3mm, granulation rate ≥ 90%, application scope: the granulator is especially suitable for the granulation of light fine powder materials. The finer the basic particles, the higher the sphericity and the better the quality of the pellets. Typical application materials: chicken manure, pig manure, cow manure, tanli, clay, kaolin, etc.
