Working principle of drum dryer

Application scope of drum dryer:

The internal structure of the chain crusher is mainly composed of the upper body, the inner lining plate, the crushing tool, the lower body, the fan, the rotor, the discharge pipe, the underframe, the bag filter and other parts. The lining plate increases the wear resistance of the equipment; The dust removal equipment solves the dust pollution problem more humanized. Workers will not be polluted by dust during operation; When entering the crushing room, the rotating tool, the tooth plate of the lining plate and the added materials are quickly crushed into powder under the combined action of the strong impact of the tool, high-speed impact and friction.

The feed inlet of the chain crusher is made of wood powder granules. The body is made of stainless steel door cover, chute and feeder. The feeding adopts frequency conversion and speed regulation to ensure uniform feeding. Ensure that the service life of mechanical equipment is extended, the product quality is improved, and the consumption cost per ton is reduced. Using the manufacturing process, you can customize the molds for various raw materials for your various wood pulverizers. The wood pulverizer effectively solves the shortcomings of difficult granulation of biomass coarse fiber and poor effect. The main drive adopts gear drive and quick-discharge hoop type. The output is about 15% higher than that of belt drive type.

When the crusher and sander is fed, an unbalanced process of about 30~60s usually occurs. In this case, the feed cannot be stopped, and the feed rate should be increased as much as possible until the vibration is reduced. When the feed particles are large, intermittent vibration will occur and return to the normal state after a few seconds. This is due to the fact that a certain throwing head of the rotor is stagnant, and the normal situation caused by the accumulation of the stored material is eliminated. tension. The rotor wear parts of the chain crusher are designed to protect the rotor body from wear. The chain crusher is mainly composed of shell, rotor, hammer, chain crusher manufacturer’s telephone, lining plate, screen plate, etc. No component has its own functions and different obligations. The price list of chain crusher and the whole crushing operation are carried out.

We may be a little unfamiliar with the organic manure composter. In the equipment for making organic manure from livestock manure, the key equipment is the organic manure composter. The composition of its materials and main parts has a very important impact on the treatment of livestock manure. Here is a brief introduction to the fertilizer pushing and fermentation scheme of the organic fertilizer turner and the advantages of organic fertilizer from chicken manure.

Fertilizer pushing and fermentation scheme of organic fertilizer turner:

1. Firstly, the chicken manure or other livestock manure, domestic garbage and other fertilizer making base materials shall be stacked on a flat ground in a strip heap: the pile width shall be equal to the width of the equipment, the height shall be as high as possible, and the length shall be as long as possible if the site is feasible, such as 100m, 50m, etc; The ground should be flat, and cement, brick and land can be used (as long as it is flat and has a certain hardness). The production of 10000 tons of fertilizer requires 5-6 mu of site.
2. Add the stacked chicken manure (other livestock manure or domestic garbage) to the biological starter (strain), with 1kg of starter (strain) per ton of fertilizer base material.
3. The straw, chicken manure (pig, cattle, sheep and other livestock manure, filter mud, sludge, domestic garbage and other agricultural and animal husbandry organic solid wastes, with a water content of 50% – 70%), starter, etc. shall be uniformly mixed and stirred with a dumper. It can deodorize in 3-5 hours, heat up to 50℃in 16 hours, and turn over again to increase oxygen when the temperature reaches 60-65 ℃. After that, when the temperature in the pile reaches 60 ℃ – 65 ℃, the pile will be turned over to achieve the effects of uniform fermentation, oxygen enrichment and temperature reduction, and the last process will be repeated until it is decomposed.
4. If the water content of chicken manure is too high, you can use the method of reflux to put the last dried fertilizer on the bottom to form a strip, and put chicken manure in the middle, so that the water on the top can be soaked to the bottom and then turned over.
5. Generally, the process of fertilization takes 7-10 days.

The actual utilization rate of chemical fertilizer in many areas is only 30% – 45%, and even lower in some areas! After applying organic fertilizer, due to its beneficial biological activity, the soil structure was improved, the soil water and fertilizer retention capacity was increased, the loss of nutrients was reduced, and the effective utilization rate of chemical fertilizer was increased to more than 50%. In addition, it can also reduce the amount of chemical fertilizer and fertilizer cost.

Benefits of organic fertilizer granulator machine processing fertilizer auxiliary chemical fertilizer

The function of the organic fertilizer tipper is to control the temperature and water, and eliminate the harm of organic fertilizer in the fermentation process. Advanced organic fertilizer tipping machine technology, no dead angle tipping. Pay attention to fermentation time, process and proportion. Next, I will introduce the matters needing attention when using the organic fertilizer tipper.

1. When using theorganic fertilizer fermentation dumperfor fermentation, ensure that the bottom of the material is ventilated and oxygen is supplied during composting. In the process of ventilation, on the one hand, it can supplement oxygen for compost materials. On the other hand, it regulates the material moisture, and on the other hand, it controls the temperature.
2. When the organic fertilizer fermentation dumper is used for fermentation, the organic fertilizer composting depth in the organic fertilizer fermentation tank is 0.8-1.5m. The pile width shall strictly comply with the process design of the fermentation tipper. The proper length can be determined according to the planned annual output. The compost depth is not high, which is unfavorable to temperature rise, fermentation and complete decomposition. If the depth is too large, it will exceed 2m. It is easy to cause insufficient ventilation and oxygen supplement, which also affects the fermentation quality.
3. When using the organic fertilizer fermentation tipper for fermentation, if the materials are stored for too long or there are too many straws, fresh feces should be added for adjustment during fermentation. How long the materials are stored, it is easy to cause the dissipation or volatilization of some organic matter.
4. When using the organic fertilizer fermentation tipping machine for fermentation, in the process of professional organic fertilizer production line, the tipping machine should be used to turn the pile. Promote fermentation and control the temperature of compost. It can control the moisture, dry and wet, and replenish oxygen, so as to achieve full maturity.
5. When using the organic fertilizer fermentation dumper to ferment, the initial fermentation maturity is generally 10 days to half a month in the fermentation process. In this process, the main purpose is to achieve maturity, and the organic fertilizer raw materials after tank fermentation usually need secondary aging and fermentation. The second fermentation lasts from three to four days to a week.
6. Different organic fertilizer raw materials are processed, fermented and decomposed differently during fermentation with organic fertilizer tipper

(1) Fermented with weeds and crop stalks (decomposed in about 25 days): crushed or chopped weeds and crop stalks (generally 3-5 cm in length) can be adjusted with 40% fecal water or biogas slurry. It can also be adjusted with 2% urea (46% nitrogen content) or compound fertilizer with equivalent nitrogen content. It can also be adjusted by adding fresh livestock manure according to the weight ratio of 3:1-4:1.

(2) Fermentation with pure excrement (it can be decomposed in about 20 days): it is appropriate to add crushed (chopped) weeds, crop straw for fermentation, and adjust the compost water content to about 60%, and the weight ratio is usually 3:14:1 to adjust fermentation.

(3) Fermented with manure (it can be decomposed in about 15 days): after directly expanding the volume of bacteria, evenly remove a layer in the enclosure. Stir it and directly pile it on the fermentation platform. Repeat the operation. If the water content is too large, add a proper amount of crushed dry auxiliary materials in the enclosure to adjust.

Poultry manure is increasingly polluting the environment. However, cow manure is rich in nutrients and trace elements and is a good organic fertilizer. The fertilizer production line develops cow dung as a compound organic fertilizer, which can not only turn waste into treasure, but also reduce environmental pollution and prevent the spread of diseases, which has good economic and social benefits.

The main features of the dryer machine are as follows

In organic fertilizer fermentation, livestock manure and other materials, domestic waste, sludge and other fertilizer making base materials should be piled on the flat ground in a choppy manner. When the tank turning machine is used to ferment organic fertilizer, the material is directly put into the fermentation tank. In the fermentation process, compost turning function is used to provide the quality of organic manure fermentation.

Organic fertilizer raw material processing and fermentation skills

The main purposes of producing organic fertilizer from feces with a pair of double roller granulators can be summarized in four aspects:

1、 Stabilization: through centralized aerobic composting and large-scale treatment, the organic matter in the feces can be degraded to achieve the purpose of stabilization and avoid secondary environmental pollution caused by material mildew and odor.

2、 It is harmless. It kills parasite eggs and pathogenic microorganisms through disinfection to prevent infectious diseases from spreading on the land and promote food safety production.

3、 Utilize resources to realize the recycling of manure, turn harm into benefit, turn waste into treasure, and provide a large amount of high-quality fertilizer for the development of organic agriculture.

4、 Industrialization will establish a new economic growth point for pig farms. Through large-scale and mechanized production of organic fertilizer plants, manure composting will be further processed into powder or granular commercial organic fertilizer

This is why the double roller granulator not only saves energy and environmental protection, but also fully reflects the green nature of organic fertilizer. The efficiency of organic fertilizer is obvious.

The organic fertilizer granulator consists of several parts. First, it is a collection of devices. Secondly, it is the most important transmission component and also a support device with special technology. Finally, there are conveyor belts and auxiliary wheels. In the future, it is very important to maintain the equipment. The dust on the equipment needs to be cleaned locally to prevent the dust from entering the machine. If the bearing temperature is too high, ginger tea is required, and parts need to be checked regularly to prevent excessive wear. The following is a detailed introduction.

Composition of organic fertilizer granulator

1. Main part: The most important part of the whole granulator is the main part, which is welded by high-quality medium carbon steel plate. Built in special rubber lining plate or acid resistant stainless steel lining plate, through strict quality control and special process requirements, automatic scar removal and tumor removal are realized, and the traditional scraper device is canceled to achieve the purpose of the machine.
2. Transmission part: the transmission part of the whole drum granulator is superior to the whole machine. The transmission frame is welded with high-quality channel steel. And passed strict quality and quantity requirements. The main motor and reducer installed on the transmission frame are ISO national inspection free products with reliable quality.
3. Support part: the whole rotating part of the fuselage is supported by the support, which bears great stress. Therefore, the support part of the machine is welded with medium carbon steel plate and channel steel. Through strict quality control and special process requirements, the machine has achieved its purpose.
4. Rolling belt: it is fixed on both sides of the machine body to support the whole machine body.
5. Big gear: it is fixed on the machine body and meshed with the transmission pinion to drive the machine body to work in reverse. It uses high-tech wear-resistant materials, so that the machine has a longer service life.

1. There may be a problem with the bearing of a part of thegranulator, which makes the machine work abnormally, the working current fluctuates, and the working current is high.
2. The annular die is blocked, or part of the die hole is separated from the material. If the annular die gets into foreign matters, the annular die will break away from the circle, the clearance between the roller and the die is too tight, the roller is worn or the roller bearing is damaged and cannot rotate, which will cause the vibration of the granulator.
3. The alignment of the coupling is unbalanced, the height and height have deviations, thegranulatorhas vibration, and the gear shaft oil seal is easy to be damaged.
4. The main shaft is not tightened, especially for D or E machines. The looseness of the main shaft will cause axial movement before and after the movement. The roller swings obviously, and the granulator is noisy and difficult to granulate.
5. The wear of big gear and small gear, or the replacement of single gear, will also produce a lot of noise.
6. The discharge of materials at the outlet of the conditioning device is uneven, which makes the working current of the granulator fluctuate greatly.
7. The new ring die must be used to prepare the new drum, and a certain proportion of sand bran must be used for grinding and polishing.
8. The tail of the hair conditioner is not fixed or fixed, and will not shake.
