fertilizer granulator Nov 10, 2023

How do small aquaculture plants configure organic fertilizer production lines? A series of organic fertilizer production lines mainly focus on the technology of decomposition, sterilization, and deodorization. They are large, medium, and small organic fertilizer equipment production lines that integrate practical and effective manure fermentation, particle processing, raw material mixing, drying, packaging, and other fertilizer production equipment processes. These processing processes are used to process livestock and poultry manure into harmless commercial organic fertilizers.

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

The main process of organic fertilizer production line equipment is to mix organic solid waste with a moisture content of less than 60%, auxiliary materials (such as plant straw), microbial fermentation agents, etc. evenly, and make them fully mature, sterilize, deodorize, and dehydrate through continuous aerobic fermentation in a pool. The moisture content of the decomposed material is generally within the range of 30-35%. After screening and magnetic separation, it can be directly used for pelletizing to produce round organic fertilizer, or further drying to produce powdered organic fertilizer.

The organic fertilizer produced by processing chicken manure, pig manure, cow manure, sludge, and straw is an organic matter long-term fertilizer, which can improve soil even if the fertilizer is effective for a long time. Vegetables and grains grown with organic fertilizers are pollution-free foods, which are vigorously promoted by the country and are also the healthy food that people are looking forward to today.

The granulation process and advantages of dry granulation roller extrusion granulation machine

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.

Using a composting machine to ferment cow manure and other raw materials – crushing the fermented organic fertilizer – stirring the raw materials evenly with a mixer – granulating with a granulator – evaporating the moisture in the particles with a dryer – cooling the particles with a cooling machine to quickly reduce the temperature – screening the unqualified particles and re crushing them for granulation – coating the qualified particles – quantitatively bagging the final organic fertilizer products. The complete set of granular organic fertilizer production line has more equipment than simple configuration, such as a stacker, dryer, cooler, and coating machine. However, the selling price of finished products is much higher than that of simple production, and the market competition is relatively strong.

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.
