The granulation equipment of organic and inorganic fertilizer production line is generally divided into the following kinds according to the different granulation modes:

1. Disc granulator

It is composed of an inclined granulated disc, a driving device, an adjustment mechanism for the tilt Angle of the disc, a frame, a feeding pipe, a liquid sprayer, and a scraping plate. The tilt Angle is 35~55 degrees and the rotation speed is n=10~18rmin. The smaller the Angle, the longer the residence time and the larger the particle. Because the disc granulator equipment investment is small, the electricity consumption is small, the operation cost is low, in the organic fertilizer production enterprise is widely used

Disc granulator is mainly used for good adhesion, powder homogenous material pelletizing: disk. Type structure, gear transmission. Production capacity :1.0~3.0 tons/hour: pelletizing rate above 70%; Material requirements are fine, need to pass 20 mesh sieve; Power :7.5~15 kilowatts, the price is generally within 30 thousand yuan

The disc granulator is not suitable for the fermentation materials with more crude fiber raw materials and a certain length. This equipment is more suitable for the fermentation raw materials based on powdery materials. If the use of disc granulation equipment recommended two grinding, otherwise, will directly affect the quality of granulation

2. Double roller extrusion granulator

It is suitable for making soluble or non-viscous particles, especially for chemical fertilizer particles. It is not suitable for granulation of organic fertilizer with viscous rice husk and chicken manure raw materials with certain water content. Easy to plug the mold hole. The need to clean the mold hole regularly, resulting in the consequence of not continuous work. Applicable to compound fertilizer, medicine, chemical, feed and other raw materials granulation, product granulation rate is high.

3. Flat die extrusion granulator

It is suitable for granulation of rough fermentation organic fertilizer. It is mainly suitable for granulation of crude fiber, such as wood chips, rice husk, cotton wilsonland, cotton seed bark, weeds and other crop straws, household waste, waste plastics and factory waste. It is also suitable for granulation of materials with low adhesion rate and difficult to form, block and rod making. It can also be used for low temperature granulation of biological fertilizer, organic fertilizer and compound fertilizer. Production capacity :1.0~4.0 tons/hour; The ball forming rate is above 95%, and the return material is less. Power :22-90 kW.

Flat die granulation machine extrusion energy consumption is large, the extrusion strength is large, there are steel waste mixed with organic fertilizer raw materials, easy to damage the granulation template, sometimes block the granulation template hole. Additional equipment care and replacement of consumables are needed. At the end of each shift, plug materials should be added and granulated to prepare for the next shift.

4. Ring die extrusion granulator

The ring touch granulator is similar to the flat die extrusion granulator, which can be widely used in medium and small aquaculture, food and feed processing, livestock farms, poultry farms and individual farmers

5. Stirring teeth granulator

The utility model relates to a new granulator, also known as a wet granulator. The equipment makes use of high speed rotary mechanical stirring force and the resulting aerodynamic force, so that the fine powder material in the machine to achieve continuous mixing, granulation, spheroidization, density and other processes, so as to achieve the purpose of granulation. The particle shape is spherical, sphericity ≥07, the particle size is generally between 0.3~3 mm, granulation rate ≥80%, the size of the particle diameter can be adjusted by the amount of material mixing and the spindle speed, usually the lower the mixing amount, the higher the speed, the smaller the particle, and vice versa. Tooth stirring granulator has high granulation efficiency, no acute Angle after granulation, low pulverization rate and easy to meet the requirements of mass production. The power is generally about 37 kilowatts. Many organic fertilizer manufacturers are using

6. Rotary drum granulator

The organic fertilizer rotary drum churning granulator is a material can be made into a specific shape of the molding machinery.Drum granulator is one of the key equipments in the compound fertilizer industry, which is suitable for the mass production of cold and hot granulator and high, medium and low concentration compound fertilizer.The main working mode is granulation by pellet wet method. A certain amount of water or steam is used to make the basic fertilizer fully react after humidifying in the cylinder body. Under a certain liquid phase condition, with the help of the rotating movement of the cylinder body, extrusion pressure is generated between the material particles to aggregate into balls.The cylinder is lined with special rubber board or acid-proof stainless steel board, which can automatically remove scar and tumor and eliminate the traditional scraper device.This machine has the characteristics of high ball strength, good appearance quality, corrosion resistance, wear resistance, low energy consumption, long service life, easy operation and maintenance, etc.Wet stirring tooth granulator USES high speed rotary mechanical mixing force and the resulting aerodynamic force, so that the fine powder material in the machine to achieve continuous mixing, granulation, spheroidization, densification and other processes, so as to achieve the purpose of granulation.The combination of these two granulation methods makes the granules with higher pellet formation rate, more beautiful appearance, energy saving and energy saving.
