Disc organic fertilizer granulator machine is a family member of fertilizer equipment, which plays an indispensable role in the production of spherical granules. There will be some problems in the use of the disc granulator. So, what problems will occur, how can we eliminate these problems?

First, the disc tilted excessively. The more problems encountered in the use of disc organic fertilizer granulators are the grasping and adjustment of inclination. In fact, there is no specific parameter for your reference, but it should be based on the formation of spherical particles. The adjustment measures are to adjust the bolts at the bottom of the disc to change the position and angle of the reducer to achieve the purpose of normal use.

Second, molding is difficult. In addition to the subjective factors of the raw material composition, the spherical particle forming of the disc organic fertilizer granulator is in addition to the subjective factors of the raw material composition, the fineness of the raw material, the water content of the raw material, the addition of the auxiliary binding component, the angle of the disk operation, the speed of the disk operation, etc It is also a problem we commonly encounter. According to the reasons for the above problems, and then make some improvements, we can reach our expected value.

Third, the particles are not uniform. This problem is a common problem in the single-machine operation of the disc organic fertilizer granulator. The treatment of such problems is generally divided into two parts. One is to improve the moisture content, and the other is to control the size of the shaped particles. Then, after drying and sieving, we narrow down our selection.

Fourth, intermittent operation. Such failures of disc pelletizers are generally caused by broken bearings, weightlessness of the disc body, and abnormal motor voltage. Shun vines, timely maintenance, can quickly eliminate the operation failure of the disc granulator.

 Working principle and application scope of organic fertilizer drum dryer

The material enters the inner layer of the rotary drum from the feeding device to realize the downstream drying. The material is continuously picked up and scattered under the inner plate in a spiral way to realize the heat exchange. The material moves to the other end of the inner layer and enters the middle layer for counter-current drying. The material is continuously lifted in the middle layer repeatedly, in a two-step and one-step way. The material in the middle layer not only fully absorbs the heat emitted by the inner drum, but also absorbs the heat of the middle drum, At the same time, the drying time is extended, and the material reaches a good drying state here. The material moves to the other end of the middle layer and falls into the outer layer. The material moves in a rectangular multi-circuit way in the outer drum. The material that has reached the drying effect moves quickly under the action of hot air and is discharged from the drum. The wet material that has not reached the drying effect cannot move quickly because of its own weight. The material is fully dried in this rectangular sheet, thus completing the drying purpose.

The round particles with high moisture content from the organic fertilizer particle shaping section are transported to the feeder of the tubular dryer through the conveyor belt, and the granular materials with chute in the feeder directly enter the rotating drying drum. With the rotation of the drying drum, the granular organic material will be brought up at a certain angle. When installing the drying main pipe and drying branch pipe, the included angle between the main pipe and the horizontal ground coincides with the material picked up. The picked up granular material buries the outlet end of the drying branch pipe, so that the granular material can fully contact with the hot air and prevent heat loss. After the particles are heated, hot water vapor will come up to the upper end of the drying drum. Under the action of high-power induced draft fan for outdoor dust removal and water vapor removal, water vapor dust, etc. will be discharged from the drying device through the air inlet. Finally, the dry organic fertilizer granule material with low moisture is discharged from the material outlet and enters the next cooling section.

Applicable scope of drum dryer:

It is applicable to grains with high water content and high viscosity, such as beer lees, starch lees, rice bran lees, and various residue materials, such as bean dregs, cassava dregs, bean dregs, sweet potato dregs, potato dregs, sugar dregs, fruit dregs, sauce dregs, livestock and poultry excrement, sludge and peat, and other high-moisture materials, and is more suitable for the treatment of livestock and poultry excrement in large, medium and small farms, the production of organic fertilizer from livestock and poultry excrement, compound fertilizer, organic-inorganic compound fertilizer, sludge, grain, food, biogas residue High humidity materials such as medicine residue.

Traditional fermentation organic fertilizer manufacturing process  covers a large area, and the annual output of 30,000 tons of organic fertilizer fermentation area needs about 3,000 square meters, while the use of organic fertilizer fermentation tanks only needs an area of 40 square meters. On the one hand, there is no need to buy so much land On the other hand, it can save the funds needed to build a fermentation shed; the fermentation time is short, the traditional organic fertilizer fermentation takes more than 20 days, and the organic fertilizer fermentation tank can be fermented twice a day, which saves time and improves efficiency. High degree of mechanization, easy operation, traditional organic fertilizer fermentation requires more labor, high labor intensity, organic fertilizer fermentation tank, and humanized design of fermentation tank, one fermentation tank or multiple fermentation tanks can be operated by one person, humic acid fermentation Tank, automatic temperature control, automatic stirring, automatic discharge, automatic feeding; wide adaptability, traditional organic fertilizer fermentation can not be fermented in cold regions in the north and cold regions in winter in the fermentation of organic fertilizers Summer, autumn and winter can be fermented throughout the year.

Advantages of organic fertilizer fermentor:

The whole process has a high degree of automatic automation, strong sealing, and no secondary pollution.

The vertical closed tank structure is adopted, which saves the occupied area, and the fermentation tank better reduces the area requirements for equipment installation.

All parts in contact with feces in the organic fertilizer fermentation tank are made of 304 stainless steel, which is corrosion-resistant and has a long service life.

The operation is fully automated, and the small fermentation tank can realize an unmanned operating system (when the conveyor belt is put in). The inside of the tank is made of polyurethane as a thermal insulation layer, which is less affected by the outside world and ensures fermentation throughout the year.

The organic fertilizer manufacturing process is mainly to screen and magnetically sort the organic waste with a water content of about 30% to 35% after fermentation and decay to prepare round granular organic fertilizer, and add functional bacteria to produce biological organic Fertilizer, adding nitrogen, phosphorus and potassium (total nutrient content less than 15%) can produce organic and inorganic fertilizers.

After the fermented organic waste is subjected to magnetic separation and sieving, the raw materials with binder and other ingredients to be compatible are metered according to the ratio requirements, and then lifted into a multi-dimensional high-efficiency mixer by a bucket elevator for rapid mixing. The mixed material slips out into the mixing bin, and is continuously and uniformly fed into the extrusion granulator by the disc feeder to make cylindrical particles; the cylindrical particles are polished and formed into spherical particles by the circular particle polishing and shaping machine, and are formed by the belt. The machine is fed into the drying, cooling and screening machine (three-in-one model). The particles are dried at a low temperature and large air volume (≤65 ℃) in the front section of the drying and cooling screening machine, and then enter the cooling section for air cooling. After sufficient cooling The material enters the screen installed at the end of the cylinder, and the sieved finished particles are transported by the elevator to the finished product silo, which is measured and packaged by the packaging system; the sifted large particles are returned to the mixing granulation system after crushing; The sieved small particles (basically without powder) can be made into small packages and sold directly.

Fertilizer manufacturing process of sheep manure and straw material fertilizer

The amount of sheep dung mixed with the appropriate amount of straw powder depends on the water content of the sheep dung. Generally, the fermentation requires 45% water content, that is, the hands are squeezed into a lump, and the fingers are watered, but there is no dripping. Scattered. Then add cornmeal and strains. The function of cornmeal is to increase sugar content for the fermentation of strains, so that multi-dimensional compound enzyme bacteria will soon have an absolute advantage.

1. Add the prepared mixture to the blender for stirring. The stirring must be even, transparent, and no raw materials are left.

2. The well-stirred ingredients are piled into long strips with a width of 1.5m-2m and a height of 0.8m-1m, and they are tossed once every 2 days with a turning machine.

3. Compost for 2 days, odorless for 4 days, loose for 7 days, become fragrant for 9 days, and become fat for 10 days.

4. The temperature can reach 60 ℃ -80 ℃ on the second day of stacking, killing E. coli, eggs and other diseases and insect pests;

5. On the 4th day, the smell of sheep dung was eliminated; on the 7th day, the compost became loose and dry, covered with white hyphae;

6. On the 9th day, a scent of distiller’s koji is issued;

7. On the 10th day, the bacterial manure will ferment and mature;

8. After a little drying, it can be crushed by a semi-wet material crusher, granulated by an organic fertilizer granulator, dried by a dryer, and then sieved by a sieving machine. The finished organic fertilizer is ready to be installed. The bag is stored.

Matters needing attention during the fermentation of organic fertilizer manufacturing process:

1. Requirements for fermentation raw materials

Fermentation raw materials (such as agricultural wastes such as feces) are preferably fresh without natural recycling.

2. Accessories requirements

Fermentation auxiliary materials (such as straw, rice bran, etc.) should have a moderate water content, strong water absorption, suitable particles or length, and should not be too large. The amount of addition should be determined according to the moisture content of the fermentation raw material.

3. The strains should be removed

Organic fertilizer fermentation strains require at least 50 grams (1 or 2) for one ton of raw materials. Considering that it cannot be evenly spread on the fermentation materials, when using it, first mix 50 grams of strains with 500 grams (1 kg) Stir any kind of raw materials such as wheat drum, sawdust, oil dry, rice bran, etc., and then sprinkle it into the fermentation material, and then stir and pile up the fermentation evenly.

4. The fermentation moisture is adjusted well

The moisture adjustment of raw and auxiliary materials is the most important, which is related to the success or failure of fermentation. Moisture requirements are: after the original accessories are mixed, hold them in a ball and fall on the ground into two pieces. The proportion of general auxiliary materials (such as straw, rice straw, etc.) is 10% to 30% (weight percentage with raw materials). If calculated according to the volume ratio of the two, it is generally 2 parts of raw materials and 1 part of auxiliary materials.

5. The length, width and height of the fermentation stack should meet the standard

It is required that the width of the fermentation product is not less than 1.5 meters, the height is not less than 1 meter, and the length is not limited.

Input of a complete set of granular organic fertilizer production line equipment and supporting facilities

1. Centralized treatment scheme of livestock and poultry excrement: build a relatively large excrement treatment station in the centralized breeding area of scale (one machine with multiple tanks). For daily treatment of livestock and poultry excrement of more than 12 tons, use a 3M span trough tipper; Build a 300-500 square meter transparent greenhouse, with several fermentation tanks built in the greenhouse (the cost depends on the local actual situation due to different materials).

2. Dispersed treatment scheme of livestock and poultry excrement: 2M span fermentation equipment is built in two farms, and the single unit price is about 200-300 square meters of glass fiber reinforced plastic shed (the cost depends on the local actual situation due to different materials)

So how to use livestock manure and crop straw to ferment organic fertilizer:

1、 Material ratio. Mix chicken manure, pig manure, mushroom residue, straw, dry soil powder, etc. in proper proportion. About 3-4 tons of fresh manure are added with 1 kg of organic fertilizer starter. The starter is diluted and evenly scattered into the manure pile, and mixed evenly.

2、 Material stacking. When making a pile, making it too small will affect the fermentation. The height of the pile is 1.5 meters to 2 meters, the width is 2 meters to 3 meters, and the length is more than 3 meters, so the fermentation effect is better.

3、 Moisture requirements. The moisture content of fermentation materials should be controlled at about 65%. Too high or too low is not conducive to fermentation, and fermentation is slow with little water; Too much water, poor ventilation, slow temperature rise and odor. If the water content is too high, straw, mushroom residue, dry soil powder, etc. can be added. If the water content is appropriate, you can grasp a handful of materials tightly, see the watermark on the finger joint, but do not drip, and disperse immediately after landing.

4、 Turn over the pile for ventilation. During the fermentation process, oxygen should be properly supplied and the pile should be turned over (several times when the temperature rises to 75 ℃ or above). The temperature of the pile should be controlled at about 65 ℃. Too high temperature has an impact on nutrients. Fifth, fermentation is completed. Generally, the fermentation can be completed in 5 to 7 days. The material is dark brown and the temperature drops to normal temperature, indicating that the fermentation is completed.

The complete set of granular organic fertilizer production line equipment includes: trough fermentation equipment – forklift silo – pulverizer – mixing mixer – disc granulator – dryer – cooler – screening machine – coating machine – packaging machine, and the equipment is connected by conveyor.

What is the role of fermented organic fertilizer (chicken manure for example):

1. Produce a variety of enzymes to control continuous cropping and root-knot nematodes.

2. It contains beneficial microbial flora, which can activate nitrogen in the air, release potassium nutrients and supplement soil organic matter.

3. The soil is soft and easy to cultivate, promoting the soil aggregate structure, releasing soil pores and promoting the growth of root groups. Keep the soil water and fertilizer.

Organic fertilizer manufacturing process by organic fertilizer granulator machine has many effects on crops. Not only can they provide nutrients needed for crop growth, but they can also enhance the stress resistance of crops.

1. Organic fertilizers contain organic matter needed for the growth of crops, a large number of elements, medium and trace elements, active microorganisms, active enzymes, etc., most of which can be directly used by crops. The action of microorganisms and active enzymes accelerates the decomposition and utilization of soil organic materials, which is beneficial to the full release of chemical fertilizers fixed by the soil, and at the same time improves the utilization rate of fertilizers.

2. There is a large amount of organic matter in the organic fertilizer, which increases the bulkiness of the frontal soil. Under the condition of high soil water content, it can ensure the normal function of crop root respiration. Under arid environmental conditions, the presence of agglomerates prevents the capillary channels of the soil from evaporating water outward, and can play a role in drought resistance and seedling protection. The organic fertilizer after fermentation contains a large amount of humic acid, amino acids, etc., which can provide drought resistance of crops. In the extreme cold weather conditions in the north, a large amount of organic fertilizer is applied in the greenhouse, which can play the role of brewing heat, heat absorption and heat preservation.

In the high-saline soil, applying organic fertilizer year after year is more effective than using chemical fertilizer alone. Related research shows that: organic fertilizer can improve soil desalination and salt tolerance.

In the production process of organic fertilizers, due to the action of microorganisms, a variety of physiologically active substances, such as vitamins, biotin, amino acids, humic acids, auxin antibiotics, etc., are synthesized. Some of these substances can stimulate crop growth, and some Can improve the disease resistance of crops, and some can enhance the lodging resistance of crops.

Organic fertilizers are complex in composition and rich in nutrients, can provide comprehensive nutrition for crops, and have unparalleled advantages over chemical fertilizers. Therefore, fruits and vegetables grown with organic fertilizers are sweet and mellow.

 How to ferment the raw materials in the organic fertilizer manufacturing process is a prerequisite. Compost fermentation generally adopts aerobic fermentation technology, which uses the metabolic activities of microorganisms to decompose the organic substances in the materials, so that the materials of the composted organic fertilizer are stable and harmless.

At present, most organic fertilizer production enterprises adopt the fermentation process of trough stacking. The main equipment is an organic fertilizer turning machine. Other fermentation methods such as flat stacking fermentation, sealed warehouse fermentation and tower fermentation are also used. The compost fermentation process is to manually control the compost materials under the appropriate temperature, humidity and air content conditions, and use the selected composite microorganisms (bacteria, actinomycetes, yeast, etc.) to degrade the organic matter in the materials and generate high temperature to kill Pathogens, insect eggs and weed seeds in solid wastes such as dead animal poultry manure, plant straws, etc., are fermented and rotted to make them stable and harmless. Finally, it is processed into commercial fertilizer through organic fertilizer equipment.

The organic fertilizer after fermentation is dark brown, its texture is soft and uniform, and it is rich in organic matter, nitrogen, phosphorus, potassium and other trace elements, various nutrients, biologically active substances, and beneficial microorganisms. It has mature soil and cultivated fields. The role of fertilizers and soil improvement. The compost fermentation process is a complex physical, chemical and biological change process. It mainly degrades organic matter under the aerobic conditions by the action of aerobic microorganisms. The factors that affect the compost fermentation cycle and the quality of the composted organic fertilizer mainly include carbon to nitrogen ratio and organic matter content. Moisture content, temperature, pH value and ventilation oxygen supply and other 6 aspects.
