Organic fertilizer from oil palm

Oil palm is an evergreen woody plant. It not only consumes a lot of nutrients, but also has the characteristics of nutritional needs. In addition to N, P, K and trace elements, the demand for cellulose is also higher. It is not enough to use chemical compound fertilizer to grow oil palm. 

Predatory use of soil will eventually lead to the deterioration of soil environment and the increase of plant diseases, which will eventually fail to produce. Special oil palm fertilizer can be processed by organic fertilizer production equipment to meet the growth needs of palm oil.

Compared with chemical fertilizer, the application of organic fertilizer in oil palm has incomparable advantages

1. Organic fertilizer has comprehensive nutrients, and long-term uniform release. Organic fertilizer is rich in nutrients needed for the growth of oil palm. Energy sources continue to supply oil palm growth. In addition to a large number of elements, it also contains medium and trace elements, which can promote the comprehensive development of oil palm.

2. Improve soil structure and enhance soil nutrients. Because the tropical soil is mostly red loess, the soil is barren, organic matter and nutrient content is low, organic fertilizer contains a lot of organic matter, which can improve soil physical properties, improve soil quality and fertilizer preservation, and prevent soil erosion.

3. Improve soil biological activity and promote the growth of oil palm. Organic fertilizer is the main energy and nutrient source of microorganisms. The application of organic fertilizer is conducive to the activity of soil microorganisms, which can produce a variety of amino acids and plant hormones, and promote the growth and development of palm oil.

Petroleum Paman fertilizer granules

Palm oil is also a good raw material for processing organic fertilizer. The waste compost can be processed into organic fertilizer after fermentation by windmill turntable. According to the growth needs of oil palm, appropriate NPK inorganic fertilizer, compost and mineral elements should be added, and special fertilizer should be produced by organic fertilizer granulator to meet the demand of oil palm.

Fertilizer Grinder Role in Production Line

Crusher is necessary for chemical fertilizer production line of chemical fertilizer plant. It can crush raw materials and is suitable for further processing of fertilizer granulator.

Crusher in fertilizer production line

When using the crusher, the following points should be paid attention to:

1. After the equipment is installed and powered on, 3kg grease must be added to the bearing housing.

2. After 72 hours of operation, grease should be added to the bearing housing.

3. When closing, the machine can be shut down after the internal materials are discharged.

4. In case of sudden power failure, it is too late for the fertilizer production line to process the surplus materials. When there is residual material in the machine, you need to manually move the triangle belt to remove the material.

5. If there is too much debris discharge, please open the screws on both sides of the machine, and then observe whether the blade is worn into arc. If the wear is a circular arc, the pin can be pulled out and the bit will continue to be used. If the wear is very serious, replace the bit with a new one.

Granulator Maintenance Tips

With the development of agriculture and the improvement of technology, market demand began to diversify. Due to its high efficiency and good granulation effect, rotary drum granulator is also very concerned. Drum granulators is an important part of NPK fertilizer production line. Its service life is related to the manufacturer's production quality, and more depends on the maintenance work of users' daily use.

How to keep the rotary drum granulator in daily production

Rotary drum granulator

1. Keep the workplace clean. After each use, the residual material inside and outside the granulator shall be thoroughly removed and the exposed machine cleaned. It is better to cover the outdoor machine with protective cover to prevent the secondary invasion of dust.

2. The gears and worm gears of the granulator are lubricated with special grease. Add grease once at a time and frequently drop oil between sliding surfaces of hinge joint between supporting gearbox and bracket. The gearbox should be thoroughly cleaned and all protective lubricants should be replaced annually after use.

3. Pay attention to the operation of fertilizer granulator. In case of serious abnormal noise, drying sound and metal friction sound, please stop using immediately and check after troubleshooting.

4. If it fails to work, check whether the power supply voltage, power plug and socket, connecting plug and socket are normal, and check the internal fault of the controller.

Pan Granualtion Equipment Working Principle

In the process of compound fertilizer powder processing, there are many factors that affect the granulation rate of disc granulator, but the influence of each parameter is not isolated, but interrelated and included. In NPK chemical fertilizer production line, the relationship between parameters should be adjusted according to the actual situation, so as to achieve the best spherical yield.

Ball forming principle of Pan fertilizer granulator

The disc is mounted at a certain inclination. The material in the rotating disc rolls rapidly with the rotation of the main body of the disc. When it rises to the highest position, it falls vertically under the block of the scraper. 

In the process of rotating the disk, it is squeezed and rolled by the disk wall under the action of centrifugal force. As a result of these all-round mechanical extrusion, rolling, collision, powder materials gathered together, with the help of the surface tension of the liquid phase, the "mother ball" is formed. With the increase of "mother ball", the particles are gradually spheroidized into complete particles, and the strength increases gradually from small to large. 

The granulation process is completed until the particle size of the finished product overflows from the edge of the disc. The disc granulator has a good classification function, so that the powder material grows from the bottom of the disc to the earth, forming particles overflow to the outer disk. 

With the increase of the diameter of the outer disk, the linear velocity of the particles increases suddenly. Particles are rolled and rubbed to form spherical particles. Larger particles are prevented from spilling into the hopper by the discharge plate and then sent to the next process by the belt conveyor.

Pan fertilizer granulator

The chemical fertilizer is also produced in different proportions of different chemical fertilizers. Due to the influence of different fertilizer types, in order to achieve high ball rate, the parameters of fertilizer granulator should be adjusted according to the specific situation, so as to achieve the best granulation effect and improve the production capacity.

Fertilizer Production Line Configurations

The new fertilizer production line project should comprehensively consider local resources, market capacity and market coverage radius. In general, the annual output of small new plants is 10000 tons (1.5 tons / hour), 20000 tons (3 tons / hour) and 30000 tons (4.5 tons / hour). The annual output of medium-sized factories is 50000-100000 tons, and that of large-scale factories is 100000-300000 tons.

The investment scale and scheme design should be made according to the following conditions: raw material resource characteristics, local soil conditions, local planting structure and main crop varieties, plant site selection, NPK fertilizer granulator selection, production automation degree, etc.

Fertilizer production line

Several equipments of chemical fertilizer production line

1. Mixer. In addition to chemical fertilizer raw materials, some cohesive materials, such as clay, can be properly added in the mixing process. During operation, the material is evenly mixed by stirring back and forth with multi-channel rotating blades.

2. Fertilizer granulator. Organic fertilizer granulator is generally used in small-scale production to meet the requirements.

3. The rotary dryer is mainly composed of drying cylinder, transmission device, support device and cylinder tail sealing parts. The diameter ranges from 80 cm to 3 m and the length depends on the drying requirements. The dryer is a cylinder inclined to a certain angle in the horizontal direction. The material is added from the high end, and the high temperature flue gas and the material enter the cylinder in parallel. As the cylinder rotates, the material moves to the lower end due to gravity. The lifting plate is welded on the inner wall of the cylinder to absorb and drop materials, and fully contact with hot air in the falling process to achieve the purpose of drying.

4. The rotary cooler can reduce the moisture content when cooling a certain temperature. It is the same as the dryer equipment, but uses space-time gas to pump from the head to the outside, so there is no need to seal the tail.

5. Combined screen is adopted for drum screen, which is convenient for maintenance and replacement. This machine has the advantages of simple structure, convenient operation and stable operation.

Pan Granulation Technology

As a fertilizer granulator which has been used for a long time in chemical fertilizer plant, pan granulator has its unique advantages. In the production of fertilizer granulation, the following factors exist in the particle uniformity.

Structure of pan pan granulator

The disc granulator adopts the whole arc structure, which effectively improves the granulation rate. Combined with non power scraper equipment, it can reduce the accumulation of materials in the granulation process and maximize the use of raw materials. In order to facilitate the flexibility and flexibility of field use, the base is firmly thickened and weighted, without the need for additional anchor screws to fix, which also helps to prevent chassis deformation. The disc granulator is very suitable for field operation, reduces the tedious installation and layout procedures, saves time and improves the work efficiency.

In the granulation stage of NPK fertilizer production line, with the continuous addition of raw materials, under the action of centrifugal force, the manufactured particles fall into the lower belt conveyor through the edge of the plate.

Pan fertilizer granulator

Elements of Pan fertilizer granulator

When the plate granulator processes raw materials, many parameters affect each other. For example, the smaller the diameter of the pelletizing disk is, the lower the disk height is, the larger the inclination angle of the disk is, and the higher the rotation speed is; if the disk height is increased, the inclination angle and rotation speed are higher. The smaller the tilt, the lower the speed.

As a NPK compound fertilizer production equipment, another factor affecting the disc granulator is the tilt angle of the disc. The angle of inclination should not be less than 35 ° during granulation, otherwise the material will stick to the disc and rotate with the disc body. With the increase of inclination angle and rotation speed, the material can avoid accumulating in the lower part without falling and rolling up and down.  More info on pan granulation process, go here with the link.

However, the larger the inclination angle is, the faster the downward rolling speed is, and the smaller the overflow particles are. The most suitable slant point of the disk is related to the diameter of the disk, that is, the slope of the disk decreases with the increase of the disk diameter. 

This is because the end velocity of particles moving along the disk surface increases as the disk diameter increases. In order to avoid the impact and fracture of other particles when the particles are down, the tilt of the disk must be reduced.

Chicken Manure Composting Methods

 Composting method of chicken manure in garden

Animal manure such as chicken manure, duck manure and cow manure can be recycled by composting, and then made into organic fertilizer for use in the garden. Chicken manure composting is not only environmentally friendly, but also conducive to the growth of garden plants. Different from the fertilizer products produced by professional organic fertilizer production equipment, this method is simple and easy to use, and can be made and used by ourselves.

Simple composting method of garden chicken manure

1. Chicken manure, grass, flowers, leaves and other wastes are mixed with water, picked up the mixture, piled up, covered with plastic fermentation, when the fermentation temperature reaches 45 ° C, diffusion cooling, when the temperature is constant, the fermentation process is solved, and fermentation can be used.

2. Raw materials (taking the production of 1 ton of organic fertilizer as an example): 1.8 tons of livestock manure, 0.3 tons of rice straw powder or leaf powder, 2.5 kg of corn flour and 1 kg of rapid bacterial starter are required. Animal excreta + leaf or grass powder + corn flour + strain + mixture + compost + air drying.

2.1. First of all, the water content of the mixed raw materials should be controlled between 40% - 50%. Then, bacteria are mixed on the surface of the mixed fertilizer, and the raw materials are evenly put into the mixer for crushing and mixing. When mixing and crushing fertilizer, the water content should be controlled within 40% - 45%. Too much or too little water will affect the quality of fermentation. Stir evenly, thoroughly and fluffy without lumps.

2.2. The mixing raw materials are stacked into straw curtains with width of 1.5-2 meters and height of 0.3-0.4 meters, covered with aerobic fermentation. Generally speaking, the temperature rises to 50 ° C in 24 hours and 60-70 ° C in 48 hours. In the fermentation process, high temperature can kill all pathogenic bacteria, eggs, grass seeds, etc. According to composting experiments, composting usually takes 6-15 days in spring, summer and autumn, and longer in winter. When the fertilizer is covered with white hypnosis, that is, all the fertilizer is rotten and can be slightly dried and screened.

3. Chicken manure contains a lot of harmful microorganisms, which can not be used directly. Deep high temperature fermentation is necessary. One is sterilization, the other is organic dyspepsia substances, increase the actual organic content.

Composting Techniques of chicken manure

1. Fermentation is mainly carried out in fermentation pair or in-vessel fermentation tank. The best way is to add appropriate amount of fermentation bacteria at the same time. The film is then covered with agriculture and the fermentation time is usually 10-20 days.

2. Chicken manure was dried and crushed after deep fermentation. Chicken manure can be used directly. But this fertilizer cannot be called commercial organic fertilizer. Compost is a high-quality organic fertilizer on the market after being processed, dried and screened by organic fertilizer pelletizer. The compound fertilizer is produced by NPK fertilizer production line and different proportions of fertilizer.
