Pan Compost Pelletizer Working Process

Disc granulator is one of the important equipment for organic fertilizer production. Its main working part is a rotating swashplate. According to the principle of agglomeration granulation of powdery materials, the powdery materials with wet surface are continuously rolled or overturned in the disc granulator equipment, and mechanical extrusion is added to promote these powdery materials to gradually form particles. 

This machine is one of the important fertilizer making equipment in compound fertilizer production. The disc granulator can be reasonably selected through the parameters of the granulating disc, so as to improve the product output and greatly reduce the product cost.

1、 Principle of disc granulator

The disc is installed at a certain angle of inclination. The material in the disc rolls rapidly with the rotation of the disc body. When it rises to the highest point, it falls vertically under the stop of the scraper. During the rotation of the disc, the particles press and roll with the disc wall under the action of centrifugal force. Due to these comprehensive mechanical extrusion, rolling and collision, powdery materials are gathered together to form a "mother ball" through the surface tension of the liquid phase. 

With the increase of "mother ball", it gradually turns into complete particles, from small to small. The granulation process is completed until the particle size of the finished product overflows from the edge of the disc. Disc granulator has good classification function. It continuously makes powdery materials grow from the bottom of the pot to form particles and overflow into the outer pot. As the diameter of the outer disk increases, the linear velocity of the particles increases suddenly. The particles roll while rounding to form spherical particles. Larger particles are blocked by the discharge plate, will not overflow into the hopper, and will be sent to the next process by the belt conveyor. 

Many disc granulators are used in NPK fertilizer manufacturing process, but they can also be used in organic fertilizer manufacturing process.

2、 Technical parameters of disc granulator

In the production process, several parameters that will affect the granulation effect of the disc granulator are: disc diameter, disc height, inclination angle and disc speed.

Generally speaking, the diameter of the disc is mainly determined by the output. Each manufacturer shall select the combination matching with other organic fertilizer equipment such as mixer or screw conveyor according to its own situation, such as annual production capacity. 

The annual production capacity of the disc granulator with a diameter of 2m can reach more than 10000 tons, and the annual production capacity of the disc granulator with a diameter of 2.2m can reach more than 15000 tons. 

Therefore, the selection of disc diameter should be based on the design annual production capacity. Come and think about it. If the fertilizer granulator in the disc granulation production line is replaced by the strand granulator, this fertilizer production line is called drum granulation.

Pig Manure into Granular Compost

Pig manure organic fertilizer granulator: whether you like pork or not, 700 million pigs are there. The problem is that the value of pig manure brought by these 700 million pigs exceeds 100 million.

Pig manure is very "fat". Today, no one will question the necessity of environmental protection in pig breeding. How to do it has become a problem that the industry really needs to think about. The same thing may look completely different from different angles. 

In some people's eyes, these hundreds of millions of tons of manure can be a source of pollution, but in some people's eyes, it can't be a source of wealth? Turn pig manure into organic fertilizer and garbage into resources. Endless troubles have suddenly become endless benefits. All problems have been solved at once?

Reality will never be as full as ideal. Whether it is a pig farm or an organic fertilizer plant, it seems that there is no real way to combine the two. The production of organic fertilizer is a completely unfamiliar technology for pig farms, which is difficult to accept huge investment. For organic fertilizer plants, the use of pig manure raw materials is also full of unknowns. The fertilizer industry even spoke frankly about the various residues of heavy metals and antibiotics.

Who can build a bridge between the two first? We habitually think of the government. The government has done a lot of work, from regulation to subsidies. But everyone knows that the market is the greatest force. We are glad to see that leading enterprises such as Wenshi, muyuan and Dongrui have made many successful attempts.

Only when everyone in the market starts to benefit from it can the 100 billion market in the pig manure organic fertilizer theory be really activated, and then the pig manure will naturally become a fertilizer difference.

Q: how does pig manure mature?

A: pig manure has fine texture, low cellulose content and high nutrients. It is a good organic fertilizer. However, due to its high water content, slow maturity and less fermentation heat release, it belongs to cold fertilizer.

Its fermentation is slower than sheep manure and horse manure. Fermentation requires a certain temperature and humidity. The fermentation temperature of pig manure should reach 60 ℃ - 70 ℃, and the water content should reach about 60%. (the judgment method of 60% water content is to knead pig dung into a ball by hand and loosen it when it is loose.) if the temperature is not enough, cover it with film or mix some horse dung well. 

When the water content is high, the feces can be opened to evaporate the water. When it is not enough, add water. In addition, adding some nitrogen fertilizer can speed up the fermentation.

The standard for good fermentation of pig manure is: the color is yellow green, there are white mycelium like substances, the smell is not strong, slightly alcoholic. The water content of pig manure is 81.5%, organic matter is 15.0%, nitrogen is 0.60%, phosphorus is 0.40%, potassium is 0.44%. High nutrient content, balanced, soft, large and long fertilizer effect, it is "warm fertilizer".

 Pig manure has fine texture and complex components, including protein, fat, organic acids, cellulose, hemicellulose, inorganic salts, etc. Pig manure contains more nitrogen and a smaller carbon nitrogen ratio (14:1). Generally, it is easy to be decomposed by microorganisms and release nutrients that can be absorbed and utilized by crops. After decomposition, it can be applied to cold soil, sandy soil and clay soil to improve the soil.

How to use cow manure fertilizer machine efficiently

In the process of organic fertilizer production, the failure of organic fertilizer equipment will affect the normal work progress, delay the production plan and cause production losses. We believe that organic fertilizer enterprises should take countermeasures to reduce the failure of organic fertilizer equipment and save funds for production.

Fertilizer production line

The following countermeasures to reduce the failure of organic fertilizer equipment are summarized for your reference:

Countermeasures to reduce the failure of bio organic fertilizer equipment:

(1) Maintain the initial and basic state of organic fertilizer equipment and maintain the original design parameters: This is the basic work, that is, the first step to reduce the failure of organic fertilizer equipment is to restore the basic state of organic fertilizer equipment;

(2) Strictly abide by the operating procedures to prevent and avoid destructive operation and overload operation: the problems of organic fertilizer equipment are mostly caused by improper operation or maintenance. The significance of standardizing employee behavior is to prevent and reduce this organic fertilizer equipment problem caused by simple reasons;

(3) Continuously discover, prevent and repair natural deterioration and repair organic fertilizer equipment under potential fault conditions: the significance of independent maintenance. One of the most important steps is to solve the problem of fault source through the participation of front-line employees in finding problems at the first time, comprehensive and standardized production maintenance, advocacy and elimination of six sources;

(4) Correct the defective design and actively maintain the accidental improvement of design and manufacturing defects of organic fertilizer equipment;

(5) Prevent man-made deterioration, man-made damage and destructive maintenance;

(6) Control any abnormal external conditions and accelerate the degradation of organic fertilizer equipment.

No matter what equipment it is, as long as it is equipment, some faults will inevitably occur. It may be due to the quality problem of the equipment, improper use, long-term use, parts wear and other reasons, and some faults will occur in the organic fertilizer equipment for a long time.
