The pig manure organic fertilizer wheeled self-propelled composting machine (walking tipper) is the main machine in a complete set of equipment dedicated to the production of bio organic fertilizers. The machine adopts a four wheel walking design, which can move forward, reverse, and turn, and is controlled and driven by one person. During driving, the entire vehicle rides on a pre stacked long strip of fertilizer base, and the fertilizer base raw materials are mixed, fluffy, and moved by a rotating blade shaft mounted 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. Advanced fermentation processes adopt microbial good fermentation, designed based on the principles of good fermentation, allowing fermentation bacteria to fully utilize their functions.

The wheeled self-propelled composting machine for pig manure organic fertilizer is equipped with a drum and knife shaped teeth, mainly used for flat stacking fermentation. It has dual functions of flipping and crushing. It can evenly mix materials and bacterial strains such as fecal base material and sludge, and effectively crush the plate lumps in the fermented materials. It is an essential specialized tool in fertilizer production operations.

The process of stabilizing organic matter in cow manure through the action of aerobic microorganisms (mainly aerobic bacteria) in the rotary fermentation composting machine. During the composting process, the soluble organic matter in the feces penetrates into the cells. Microorganisms decompose and metabolize a portion of the organic matter through their own biological metabolic activities, that is, oxidize and decompose it to obtain the energy required for biological growth and activity, and convert the other portion of the organic matter into new cellular matter, enabling the growth and reproduction of microorganisms to produce more organisms.

The wheeled self-propelled composting machine for pig manure organic fertilizer is more suitable for the mechanism and process requirements of microbial fermentation and storage of manure into fertilizer. It can effectively mix thick stored manure with microbial preparations and straw powder. Not only is the fermentation speed much faster than deep tank fermentation, but it also effectively prevents the generation of harmful and odorous gases such as hydrogen sulfide, ammonia, and indole during the fermentation process, which meets environmental requirements and can produce high-quality organic fertilizers.

Organic fertilizer granulator includes: disc granulator, new organic fertilizer granulator machine, drum granulator, roller extrusion granulator, etc. The most commonly used granulation equipment is the above. In the production of organic fertilizer, the selection of the granulator is usually determined according to a variety of factors, such as raw materials, output, and price.
The new organic fertilizer granulator machine is a granulating equipment specialized in the production of organic fertilizer. It is also called an internal stirring tooth granulator. It is suitable for granulating materials with relatively large fibers. The shape of the finished product is oblate and needs to be processed by a rounding machine. It can be processed into a circle.

Both the drum granulator and the disc granulator belong to the agglomeration method.Compared with the disc granulator, the drum granulator relies on the temperature of the high granulation to increase the amount of liquid in the basic material, and promote the material to be more Balls are formed under low water content, which has the advantages of easy drying, energy saving and consumption reduction. But when the process conditions are not well controlled, the return material is high.
The roller extrusion granulator is a room temperature granulation equipment. It does not produce a large amount of dust and smoke during work. It has a wide range of applicable materials and can granulate materials that cannot be processed by other granulators. The high rate, the disadvantage is that the output is not very high, usually it is necessary to configure several pairs of roll extrusion granulators to work at the same time.

How to use an organic fertilizer flipper to produce pig manure organic fertilizer

fertilizer granulator Nov 10, 2023

Pig manure is a commonly used organic fertilizer raw material, which is fermented to become a high-quality organic fertilizer with a wide range of uses. However, using natural fermentation pig manure to make organic fertilizer takes 1-3 months, which makes friends who want to make their own organic fertilizer stay away. For this issue, organic fertilizer flipping and throwing machine equipment has emerged. Using the flipping and throwing machine to produce organic fertilizer can shorten the time to less than one month. So how can we use the organic fertilizer flipping and throwing machine to produce pig manure organic fertilizer?

Method for producing pig manure organic fertilizer using an organic fertilizer flipper:

1. Preparation and adding bacteria: Prepare the feces that need to be fermented, preferably fresh pig feces (the fermentation effect of fresh feces is better than that of old feces), such as adding 0.25 kilograms of pig manure fermentation agent to about 1 ton of fresh pig feces. First, mix the pig manure starter with rice bran (or corn flour, wheat bran) in a ratio of 1:5~10 for standby.

2. Pig manure pile construction: Build a pile of prepared pig manure while spreading bacteria. The height and volume of the pile should not be too short or too small. Requirements: the pile height should be 1.5 to 2 meters, the width should be 2 meters, and the length should be unlimited.

3. Adjust moisture. The moisture content of fermented pig manure should be controlled between 40-65%. Moisture judgment: Grasp a handful of pig manure tightly, see watermarks on the fingertips but do not drip, and it is advisable to scatter it upon landing. Less water leads to slow fermentation, and more water leads to poor ventilation, which can also cause “spoilage bacteria” to work and produce a foul odor. Therefore, it is important to control the moisture content.

4. Starting temperature. The starting temperature should be above 15 ℃, which is suitable for operation in all seasons and not affected by the season. In winter, it is recommended to ferment indoors or in a greenhouse, and the fermentation temperature should be controlled below 70-75 ℃.

5. Mix well and ventilate. Pig manure fermentation agents require aerobic fermentation, therefore, during the operation process, oxygen supply measures should be increased to achieve mixing, flipping, and aeration. Otherwise, it will cause anaerobic fermentation and produce a foul odor, which will affect the fertilizer effect.

6. Fermentation completed. Generally, after 48 hours of pig manure accumulation, the temperature rises to 50-60 ℃, and can reach over 65 ℃ on the third day. At this high temperature, the pile needs to be turned over once. Generally, there will be two times of high temperatures above 65 ℃ during the fermentation process. Turning over the pile twice can complete the fermentation, and it can be completed within a normal week. The material appears black brown and the temperature begins to drop to room temperature, indicating the completion of fermentation.

What are the granulation equipment and methods for NPK fertilizer production line

fertilizer granulator Nov 10, 2023

There are four types of granulation in the NPK fertilizer production line on the market: 1. Disc granulation is suitable for small output devices, and generally does not exceed 50,000 tons/year. It is the primary stage of drum npk fertilizer granulation. 2. The drum npk fertilizer granulator is widely used, and the pellet size is also better, including drum ammoniation granulation and drum agglomeration granulation. Among them, the ammoniation is divided into one-step ammoniation and two-step ammonia The two-step amination method includes the amination reaction in the conversion tank and the amination reaction in the granulator. 3. Shotcrete granulation is the predecessor of ammoniated granulation and the technology is relatively mature. 4. High-tower granulation means that the raw materials are sprayed through the high-tower in a molten state at a high temperature. The pellets are formed into pellets during the falling process. The pellets are relatively strong and smooth. The pellets generally have a small hole, dissolve faster, and have obvious fertilizer efficiency. The market prospect is better. 

The rotary drum npk fertilizer granulator sprays water vapor at a constant pressure on the material, so that the material obtains moisture while being applied with a constant pressure to form small particles, which are formed into particles of a fixed size during the process of rotation. The humid granulation environment allows the drum granulator to produce a compound with a high content of nitrogen, phosphorus and potassium, but the cost is relatively low.
Advantages of the drum npk fertilizer granulator: By increasing the granulation temperature, the liquid content in the basic material is increased, which promotes the material to form a ball at a lower water content, and has the advantages of easy drying, energy saving, and consumption reduction.
Disadvantages of drum npk fertilizer granulator: When the process conditions are not well controlled, the return material is higher than that of the disc granulator.

Application of disc granulator in granular organic fertilizer production line

fertilizer granulator Nov 10, 2023

The disc granulator is suitable for granulating round fertilizer granules of compound fertilizer or organic fertilizer, which is convenient for transportation and storage. In order to produce fertilizer granules with balanced nutrition, a proper granulator is your ideal choice. We are a professional fertilizer factory and will provide you with practical guidance on fertilizer granulation.

The disc granulator takes the motor as the power to drive the inclined disc to rotate. The internal scraper prevents the material from sticking to the bottom of the disc. When the material rotates to the top, it will roll down by itself, just like a snowball. It is suitable for non viscous powder materials.
Some customers have seen the process of organic fertilizer processing and want to process feed pellets, but they don’t know whether the disc pelletizer is suitable. The answer is: yes. Because the characteristics of feed ingredients and organic fertilizer ingredients are basically similar, this equipment is wet granulation, which has a wide range of applicable raw materials. When we use the disc granulator for processing, sometimes the particles are larger and sometimes smaller. The way to solve this problem is to adjust the moisture of the material.
When purchasing an organic fertilizer granulator machine, customers must choose a manufacturer with a certain technical strength and perfect after-sales service. Nowadays, there are many companies producing organic fertilizer granulators in the country, and some companies have no technology at all, and they are completely imitated by other manufacturers. During production, the quality of the organic fertilizer granulator machine manufactured is not up to standard, and some of them cannot be used normally.

How to select suitable organic fertilizer production equipment for farmers based on their scale

fertilizer granulator Nov 10, 2023

How should farmers configure suitable organic fertilizer production equipment based on their breeding scale? Firstly, the livestock and poultry manure generated by the scale of breeding needs to be sufficient for the normal fermentation production of the organic fertilizer production line. The production capacity of the organic fertilizer production line is very large, producing 2-20 tons of organic fertilizer per hour.

If the production scale of livestock farms is too small and poultry manure is used as the raw material for organic fertilizer production, the raw material for organic fertilizer will be insufficient. Joining the introduction of an organic fertilizer production line would result in most of the equipment being in a stagnant state, which is clearly not cost-effective. We all know that the water content of poultry and livestock manure is relatively high, and the water content requirement of organic fertilizer cannot be higher than 30%. Therefore, the amount of poultry and livestock manure required to produce one ton of organic fertilizer should be higher than one ton. If the scale is insufficient, simple composting fermentation can be directly returned to the field. If the labor of composting is too strong, organic fertilizer flipping machines can be used.

The whole machine of the chicken manure organic fertilizer tipping machine adopts high-strength chain transmission, hydraulic control lifting, and this machine adopts a unique track design, which can use multiple slots and one machine. This not only changes the shortcomings of low production of traditional light rail tipping machines, but also overcomes the high cost of transmission accessories for conventional gear racks and light rail driving tipping machines.

The chicken manure fermentation and tipping machine has the characteristics of good maneuverability and high output rate, which can effectively improve labor productivity, save manpower, and achieve the goal of reducing production costs and improving product quality; It is a new type of product with low investment and high returns; It also has functions such as stirring and crushing, and is an essential key equipment for fertilizer making enterprises. It largely replaces manual operations, reduces human labor, and improves work efficiency.
