Simple operation of dry powder extrusion granulation equipment double roller granulator

fertilizer granulator May 17, 2023

The double roller granulator mainly relies on the external pressure mode, so that the materials are forced to pass through the gap between the two opposite rotating rollers and compress into pieces. The actual density of the material can be increased by 1.5-3 times to reach a certain strength standard. It is especially suitable for increasing the proportion of product stack. The equipment is not only scientific and reasonable in structure, but also low in investment, quick in effect and good in economic benefit.

The working principle of dry extrusion double roller granulator is very simple, and it has four functions
1. In order to ensure the continuous feeding of fertilizer granulation machine during extrusion granulation, screw conveyor and vibrating conveyor are generally used as feeding equipment;
2. Then there is the forced feeding system, which is to control the feeding speed. As if the feeding speed is uniform, it can increase the feeding amount and increase the output. Its biggest function is to pre degass and apply pressure in advance, so as to make the product quality higher;
3. Double shaft output is adopted for roll extrusion, which can effectively improve the speed of transportation, protect the bearing capacity of the main shaft, reduce damage and improve the transmission effect. It can make the hydraulic cylinder have stable pressure and make the floating roller heel run smoothly.
4. Granulation: the material sent through the conveyor driven by the motor is crushed by the chopping system, and then the powdery material is evenly added into the binding plate for shaking, and then enters the roller mouth after forced degassing and pre pressing. According to the requirements of the particle specifications, with the rotation of the roller, the molding is gradually achieved. Then the automatic demoulding process is completed.
The pig manure organic fertilizer production line adapts to the strategy of commercializing organic fertilizer management and promotes the formation of the production industry chain. It is a process equipment that integrates industrialization, marketization, and large-scale production development, which is conducive to the sustainable development of agriculture. Not only does it effectively promote the development of ecological agriculture, but it is also a choice for the development of agricultural circular economy.

Method for processing fertilizer in pig manure organic fertilizer production line

fertilizer granulator May 17, 2023

Organic fertilizer machine can solve the problem of manure emission perfectly, and the treated manure can bring additional income to pig farms. Pig farms can sell the treated pig manure to organic fertilizer producers. After a series of processing, the pig manure can be processed into nutrient rich ecological organic fertilizer. Only through sufficient composting and fermentation, can the parasites, eggs and infectious bacteria in pig manure be inactivated through the process of composting and fermentation. Let’s share the details of pig manure fermentation process.

A. Raw material particle size: In order to achieve the granulation size of the organic fertilizer granulator, the particle size of pig manure and auxiliary raw materials must be below 10mm, otherwise it needs to be crushed;
B. Suitable material moisture: The optimum fermentation humidity for composting microorganisms is 50-60%, and the ultimate humidity is 60-65%. Therefore, it is best to adjust the material moisture to about 55-60%. When the moisture reaches more than 65%, there is a higher chance of dead tank without fermentation.
C. Pig manure and auxiliary materials control: According to local agricultural conditions, the production process of pig manure fertilizer can use organic matter such as straw, corn stalks, and peanut stems as auxiliary materials. The ratio of pig manure and auxiliary materials can be adjusted according to the requirements of fermentation water. (Generally 3:1), the composting auxiliary materials can choose the raw materials with a carbon to nitrogen ratio of 20~80:1. Therefore, common dry straw, corn stalks, fallen leaves, soybean stems, peanut stems and other organic matter can be used as auxiliary materials for composting and fermentation after being crushed.
D. Fermentation cycle: After pig manure, auxiliary materials and inoculation materials are mixed in the tank, the first time is turned over, recorded as the start time of the fermentation cycle, generally after 3 to 4 days of heating period (5 to 7 days in winter), the high temperature fermentation stage . Taking the temperature as the standard, when the temperature of the pile body exceeds 60-70℃, keep it for more than 24 hours, and the compost windrow turner can be used for turning the pile. The number of turning the pile varies with the season. The summer fermentation period is generally 15 days, and the winter fermentation period is 25 days.
E. If 10 days after entering the trough, it is found that the temperature in the fermentation tank has not exceeded 40°C, it can be judged as a dead tank and fermentation start-up failed. At this time, the moisture in the tank must be measured. If the moisture exceeds 60%, auxiliary materials and inoculation materials need to be added, and the organic fertilizer machine is mixed; if the moisture is less than 60%, consider whether the amount of inoculation materials is insufficient.

Characteristics and processes of equipment for fermenting organic fertilizer raw materials

fertilizer granulator May 17, 2023

Organic fertilizer fermentation equipment is suitable for the mixing of solid and solid (i.e. powder and powder) and solid slurry (i.e. powder and slurry) in organic fertilizers, pesticides, veterinary drugs, food, biology, aquaculture, and composite fertilizers. It is also particularly suitable for the mixing of viscous materials and plays a huge role in obtaining organic fertilizers. Many equipment users are eager to understand the product structure and working principle of organic fertilizer fermentation equipment,

1. The structural characteristics of organic fertilizer fermentation equipment.

The structural characteristics of the organic fertilizer fermentation equipment are composed of a U-shaped container, spiral belt stirring blades, and transmission components; The U-shaped long cylinder structure ensures small resistance movement of the mixed materials (powder, semi fluid) within the cylinder. The positive and negative rotating screw bars are installed on the same horizontal axis, forming a low power and efficient mixed environment. The spiral shaped blades are generally made into two or three layers, with the outer spiral converging the material from both sides to the center, and the inner spiral conveying the material from the center to both sides, which can form more eddies in the flow of the material. Accelerated mixing speed and improved mixing uniformity.

2. The discharge method of organic fertilizer fermentation equipment.

Organic fertilizer fermentation equipment discharge method: The powder material adopts a pneumatic large door structure, which has the advantages of fast discharge and no residue; High fineness materials or semi fluid materials adopt manual or pneumatic butterfly valves, which can be equipped with heating or cooling jackets. There are two heating methods: electric heating and thermal oil heating. The cooling process can directly inject cooling water into the jacket, which has a large heat exchange area and fast cooling speed. The small model mixer adopts the direct connection method of the reducer, with a simple structure, high reliability of operation, and convenient maintenance. The large-sized mixer is driven by a belt pulley driven cycloidal reducer, and the elastic connection of the belt drive has the advantage of protecting the transmission components in case of overload.

The fermentation production of organic fertilizer requires a series of processes to process in order to convert animal manure and materials into organic fertilizer. During the treatment process, the first issue to be addressed is the fragmentation of feces. Which equipment in the organic fertilizer production line is used to solve this problem,

The vertical chain crusher is applied at the front end of the organic fertilizer production line to break large blocks of organic materials formed by aerobic fermentation, facilitating the powder fertilizer production process and particle fertilizer production process at the back end of the organic fertilizer. Due to the moisture content of fermented organic materials ranging from 35% to 45%, the materials are relatively wet and sticky, resulting in low crushing efficiency using traditional crushers, which can easily cause equipment blockage, overcurrent, and other issues that affect production. This chain crusher is specifically developed for the characteristics of organic materials, and is used to break large organic materials into small powdered organic fertilizer materials.

The principle is that large pieces of material slide into the crusher through the feeding port and pass through multiple layers of high-speed rotating crushing chains through the action of gravity. Finally, they are crushed by the high-speed rotating crushing to form a powder material and fall into the next process in a whirlwind shape from the material port.

The treatment mode and advantages and disadvantages of organic fertilizer fermentation equipment for feces

fertilizer granulator May 17, 2023

Organic fertilizer fermentation equipment is currently widely used in organic fertilizer production lines, which can improve production efficiency and produce high-quality organic fertilizers. Before producing organic fertilizers, it is necessary to treat the feces to achieve the best results.

The treatment mode and advantages and disadvantages of manure before the production of organic fertilizer fermentation equipment:

1、 Drying chicken manure mode. Its process involves directly passing chicken manure through high temperature, heating, sterilization, and drying, and finally producing dry chicken manure with a moisture content of about 13%, which is sold directly as a product. There are many manufacturers adopting this mode of production,

The advantages of this mode are: 1. Large production volume and fast speed; 2. The product has stable quality and low moisture content.

But there are also drawbacks: 1. The exhaust gas generated during the production process pollutes the environment. 2. The energy consumption during the production process is high, reaching around 200 yuan per ton. 3. The product only has a dry surface and still has a foul odor and secondary fermentation after soaking in water, making the quality of the product unreliable. 4. The equipment investment is large and the utilization rate is not high. 5. The organic content in chicken manure does not meet the standard.

2、 Direct drying mode. Its main process involves manually spreading and drying chicken manure, crushing it, and packaging it for sale as a product.

The advantages of this model are: low product cost and simple operation;

But it also has drawbacks: 1. It occupies a large area and pollutes the environment. 2. There is still a problem of timeliness and seasonality in air drying, which cannot be produced continuously in a factory. 3. The product has a large volume, low nutrients, and secondary fermentation, making it difficult to ensure the quality of the product.

3、 Biological fermentation mode. It mainly has the following three fermentation modes:

(1) Fermentation in a fermentation tank. The main process flow is to mix chicken manure, peat, and sawdust into a cement tank, ferment with oxygen, crush them after fermentation, and screen and package them into products. The advantages of this model are that the production process is simple and convenient, with less investment and low production costs. The main drawbacks are: 1. The product has low nutrient content and high moisture content, which cannot meet the requirements for commercialization. 2. The degree of continuous factory production is low, and the production cycle is long.

(2) Direct composting. The main process involves mixing chicken manure with straw or peat, with a height of about 1 meter. High temperature composting is used, and regular aeration fermentation is carried out. After fermentation, it is used as a product. The advantages of this model are: simple production process, low investment, and low cost. The main problem lies in 1. The product stacking time is too long, and it is greatly affected by various external conditions, making it difficult to ensure the quality of the product. 2. The degree of continuous factory production of products is not high, and the production cycle is long.

(3) Tower fermentation. The main process flow is to mix chicken manure with auxiliary materials such as sawdust, and then add biological agents. At the same time, the tower automatically flips and ventilates, using biological growth to accelerate chicken manure fermentation and deodorization. After a fermentation cycle, the product is basically the product that comes out of the tower. This model has the advantages of small footprint, low energy consumption, low pollution, and high degree of industrialization. However, its current problems are: 1. Relying solely on the biological heat generated by fermentation to remove moisture, the moisture content of the product cannot meet the requirements of commercialization. 2. At present, the process flow is not running smoothly, resulting in a significant increase in labor costs and the output cannot meet the design requirements. 3. The serious corrosion problem of the equipment has hindered its further development.

The self-propelled organic fertilizer composting machine is highly favored by customers because it can easily help them produce organic fertilizers. Organic fertilizer fermentation equipment, as a specialized machine for producing organic fertilizers, has a very broad market. This series of organic fertilizer high-temperature fermentation equipment is a high-tech fermentation equipment independently developed by a mechanical company, which can be matched into a fully automated production line according to customer needs and financial capabilities. Two to four workers can complete continuous production operations.
