fertilizer granulator Mar 4, 2023

lthough cow dung is a good raw material for organic fertilizer, if it is not fermented, it will still emit a bad smell, and will cause disease and insect pests and the risk of burning roots and seedlings. In fact, in recent years, with people’s attention to green and healthy food, the sales market of organic fertilizer is also getting better and better. Let’s see how cow dung can be made into organic fertilizer.

First of all, we should carry out fermentation. The main purpose of fermentation is to make the cow dung fully decompose at high temperature, so that the bacteria and weed seeds in the dung will be eliminated. The same beneficial fermentation bacteria added will multiply a large number of beneficial microorganisms and improve the various beneficial trace elements of organic fertilizer. During fermentation, we should adjust the carbon and nitrogen ratio of about 25:1, water content of about 55%, and then put in the fermentation agent, The fermentation cycle is about 15-20 days. During this period, it is necessary to carry out regular mixing and temperature control to make the raw materials better contact with oxygen, so as to achieve the goal of accelerating fermentation and ripening. If it is a small amount of operation, we can use manpower or a small agricultural forklift to carry out the tipping treatment. If the amount is large, we need to use a professional cow manure organic fertilizer composter. After the end of the fermentation cycle, our cow manure organic fertilizer will be fermented. However, the organic fertilizer fermented in this way is relatively crude, only suitable for self-use or short-distance sales, and the profit point is also very low. If it can be made into commercial organic fertilizer, the profit per ton should be at least 200-300.

If we want to produce commercialized organic fertilizer, we need to carry out further processing. Powdery organic fertilizer needs to be broken into powder by using cow manure organic fertilizer crusher, and granular organic fertilizer needs to be made into cow manure granular fertilizer by using organic fertilizer granulator. Therefore, we need to determine the production process of organic fertilizer according to the market situation, and determine the production process, so we can configure a complete set of equipment production plan targeted.

The trough-type organic fertilizer composter has a reasonable overall structure, good rigidity, balanced stress, concise, solid, safe and reliable performance, easy operation, and strong applicability to the site. Except for the thick frame, all parts are standard parts, which is convenient for use and maintenance.

Trough-type composter solves the problems of difficult granulation of biological coarse fiber and poor effect. The main machine adopts belt drive, and the ring mold adopts quick-release hoop type. To ensure uniform feeding, the door cover is equipped with a forced feeder, and the designed fully automatic control electric heating device can immediately adjust the dry and humidity of the material. The pressure angle can be automatically adjusted by using the principle of two-way rotation of the thrust bearing, so that the material will not be squeezed or stuffy.

Adjust the clearance between the composter template and the pressure wheel, and the proper pressure can make the ripening degree and compactness of the particles reach a good effect. The tipping machine carries out high wear-resistant heat treatment on the flat die and press roll. The cost of high wear-resistant parts is relatively low, the particle forming rate is high, and the particle strength is high.

The structural configuration of the trough type organic fertilizer composter is as follows:

It is composed of transmission device, lifting device, walking device, tipping device, transfer vehicle and other main components.

The motor directly transmits the power to the cycloidal pinwheel reducer through the sprocket to the tipping drum. The mixing blades on the drum are spirally distributed, which can turn and stir the materials in the fermentation tank to a distance of 0.7-1m, achieving the effect of fast tipping speed and uniform mixing, so as to achieve full contact between the materials and the air, making the fermentation effect of the materials better.

Power transmission device: This device is composed of motor, reducer, sprocket, bearing seat, main shaft, etc. It is an important device to provide power for the tipping drum. Traveling device: the device is composed of traveling motor, transmission gear, transmission shaft, traveling sprocket, etc. Lifting device: the device is composed of winch, coupling, transmission shaft, bearing seat, etc.

Overturning device: the device is composed of sprocket, support arm, overturning drum, etc. Transfer vehicle: This device is composed of traveling motor, transmission gear, transmission shaft, traveling wheel, etc. It provides a temporary carrier for the slot change of the tipping machine.

At present, many pig farms set sewage pipes underground, which does not occupy the ground area and can separate the sewage pipes, that is, set underground sewage pipes; The blister dung process and the leaky floor are both better ways to treat the underground sewage.

The sludge fermentation organic fertilizer composter is a kind of tank-type fermentation overturning equipment; Tank type composter is a time-saving and power-saving overturning and dumping equipment for fermenting organic fertilizer, which is divided into shallow tank type composter, deep tank type composter and automatic lifting type composter.

The organic fertilizer composter is a widely used organic fertilizer composting equipment at present. It includes a ground walking type composter, a hydraulic crawler type composter, and a trough type composter (dumper). It has the advantages of high fermentation material accumulation, large turnover yield, and material turnover and bottom removal. It is a good choice for large-scale organic fertilizer fermentation, especially for organic fertilizer manufacturers with high cost. The unique track design not only changes the disadvantages of low output of the traditional composting machine that only uses light rail, but also overcomes the disadvantages of high cost of conventional rack and light rail drive and tipping machine drive accessories.

Compared with other composters and fermentation methods, the trough composter has the advantages of high yield, small area of dumping site, material dumping and bottom removal, more moisture reduction in the fermentation process, stable operation of equipment, and low failure rate. Therefore, it is a common equipment for fermentation of organic fertilizer. Tank type composter (tipping machine) is an organic fertilizer fermentation equipment, which is applicable to the industrial fermentation treatment of organic solid substances such as animal manure, domestic garbage, sludge, crop straw, etc., and also can be used for feed fermentation. This product is divided into two series of products, namely, straight tower type fermentation equipment and tank type tipping fermentation equipment; The tank type fermentation equipment adopts the ground tank structure. According to the plant structure, a series of fermentation products for multiple tanks can be designed. It has the characteristics of simple operation, short fermentation cycle, full fermentation, small pollution, and convenient expansion.

As a new type of machinery, the organic fertilizer composter is still unknown in the national product catalogue, but it has rapidly multiplied in the fertilizer machinery and equipment family, becoming a tool to replace the manual and forklift tipping, and is the mainstream product affecting the development trend of the compost industry. Organic fertilizer composter is the core equipment of aerobic dynamic composting, and its importance stems from its role in composting production:

1. Mixing effect in raw material conditioning

In order to adjust the C/N ratio, pH and water content of raw materials, some auxiliary materials must be added into the compost. The main raw materials and various auxiliary materials are roughly stacked together in proportion, and can be mixed evenly through the stacker to achieve the purpose of tempering.

2. Adjust the temperature of raw material pile

During the operation of the organic fertilizer composter, the raw material particles are fully mixed with the air, so that a large amount of fresh air can be stored in the material pile, which is conducive to the active generation of fermentation heat by aerobic microorganisms and the increase of the pile temperature; When the temperature is high, adding fresh air can reduce the chimney temperature. It forms a state of medium-high temperature-medium temperature-high temperature alternation, and various beneficial microorganisms grow and multiply rapidly in the temperature range suitable for beneficial microorganisms.

3. Improve the permeability of raw material pile

The tipping system can process the materials into small pieces, making the thick and dense raw materials bulky and elastic, and forming appropriate pores.

4. Adjust the water content of raw material pile

The suitable water content of raw material fermentation is above 55%, and the water content standard of finished organic fertilizer is below 20%. In the fermentation process, biochemical reaction will produce new water, and the consumption of raw materials by microorganisms will lead to the loss of carrier and dissociation of water. Therefore, the water content will decrease in time with the fertilizer making process. In addition to the evaporation formed by heat conduction, the overturning of raw materials by the tipper will also form forced water vapor discharge.

5. Special requirements for composting process

For example, crushing raw materials, giving raw materials a certain shape or realizing quantitative replacement of raw materials.

The organic fertilizer composter is mainly applicable to farms of various scales, and its application value is worthy of affirmation. The production of organic fertilizer in the fermentation tank mode is to place raw materials in the fermentation tank, and the materials will be overturned, stirred and broken in the tank, so that the materials can be fermented, matured and degraded. It is easier to obtain stable product performance than static compost, and the odor control effect is better.

Working Principle

Small organic fertilizer production line for treatment of livestock manure

fertilizer granulator Jan 30, 2023

Small-scale organic fertilizer production line is mainly used for livestock manure organic fertilizer processing production line project. It is characterized by low overall investment price, low cost and low technical requirements, which is suitable for large-scale planting and breeding enterprises and small fertilizer plants.

Finally, according to the desired form of organic fertilizer, it can be divided into powder organic fertilizer and granular organic fertilizer. Different forms of fertilizer require different production line equipment. Because the configuration, specification and required equipment of organic fertilizer production line are different, the price will also affect the quotation.

The production of powdery organic fertilizer is based on the fine crushing treatment after the fermentation of organic fertilizer. The required equipment: fermentation tipper, forklift silo, semi-wet material crusher, drum screening machine, automatic packaging scale. The price of the smallest powdered organic fertilizer production equipment is about 100000 yuan.

At present, the production process of granular organic fertilizer is the most complex, and it is also based on the continuous fermentation process and the wages of powdered organic fertilizer. Therefore, the equipment required is also relatively comprehensive, including fermentation tipper, forklift silo, semi-wet material crusher, horizontal mixer, stirrer granulator, rotary dryer, rotary cooler, drum screening machine, coating machine, and automatic packaging machine. Dynamic batching scale is also required in case of special process requirements. The price of the complete set of equipment with the minimum specification is about 200000 yuan.

In terms of production scale alone, the small-scale organic fertilizer processing plant takes the annual output of 5000 tons to 10000 tons as the standard, which is also the most selected production line scale for investors who are new to the industry. The complete set of equipment is composed of many kinds of equipment. Their type selection, specification and quantity directly affect the final price of the production line. That is to say, the price of the production line with the same output is not the same, even very different. Under the same output, the powdery production line is much cheaper than the granular production line, but the corresponding powdery finished organic fertilizer is not as expensive and profitable as the granular organic fertilizer. Finally, it is suggested that you should pay attention to two points: first, raw material procurement; The second is marketing. These two aspects are very important. In short, the same sentence: entrepreneurship is risky, and investment needs to be cautious.

As an important equipment of organic fertilizer fermentation, compost turning machine lays the foundation of organic fertilizer products. Only after good fermentation can organic fertilizer be completely harmless and can be used with confidence.

Among the composting equipment, we recommend the track-type fermentation pile turning machine, which is suitable for the production of organic fertilizer plants.

Ways of compost processing by orbital turner machine

1. The track type turner adopts groove type turning mechanism with unique turning mode. Each turning can ensure that every detail of the material is in full contact with the air, replenish oxygen and discharge moisture. The contact part between the mechanism and material is small, and the maintenance is convenient. The compost is suitable for granulation of fertilizer granulator.

2. The trough turning machine adopts a long-span bridge structure, which has two series, i.e. longitudinal span bridge type and cross bridge type. The longitudinal span bridge structure makes the moving direction of materials perpendicular to the track, and the equipment span meets the requirements of fermentation period. The length of track in fermentation area can be selected according to the treatment capacity requirements within a certain range. The increase of track length in fermentation area can increase the yield of finished products by multiple times.

3. The production process has good reliability and the energy consumption is reduced because of the track operation mode of the fermentation equipment. The compost turner is reliable and has long service life.

Composition and characteristics of chain crusher in organic fertilizer equipment

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.

Pushing and fermentation scheme of organic fertilizer turner

fertilizer granulator Jan 7, 2023

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.
