pig manure bio organic fertilizer production line
The pig manure bio-organic fertilizer production line is processing fresh pig manure and other poultry manure into bio organic fertilizer. Bio organic fertilizer production line including two main parts: fermentation process and granulation: Hydraulic type groove turning machine, fertilizer crushers, horizontal mixer, new type organic fertilizer granulator, rotary dryers, coolers, screens, packing machines, belt conveyors and other equipment. all these equipments are meeting the demands of environmental protection and low cost, energy-saving, high output and high economy.
Production process of pig manure bio organic fertilizer production line:
1.Pig manure half- wet material crusher:
The pig manure after fermented and composted need to be crushed with NPK inorganic fertilizer and other additives proportioned and mixed in proportion. According to many years of experience, half- wet material crusher will crush the pig manure thoroughly, and crushing size should meet the requirements of fine powder for granulation. which is not easy to stick to the wall, not easy to block, multi-layer turbulent chain hammer structure to improve the crushing performance.
2.Automatic batching system
Continuous batching scale adopts computer automatic control, dynamic display of formula, can store multiple formulas, high batching accuracy, easy production statistics and management.Adopting automatic batching is the fundamental means to realize strict composition formulation and avoid the error of manual batching.
This series of horizontal mixer is a new kind of mixing equipment which made by our company. The machine has the advantages of high mixing degree and little residue, so that it is suitable for mixing the organic fertilizer and inorganic fertilizer.
4.New type organic fertilizer granulator
New type Organic fertilizer granulator is suitable for directly granulation of pig manure after fermentation. Before granulation, it is not necessary to dry the raw materials and directly add ingredients after crushing the raw materials to produce spherical pig manure granules. The raw materials can contain water between 30% and 40% and the pelletization rate is above 96%.Save the drying process, greatly reduce the manufacturing cost, the organic fertilizer granulator makes 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 size of the particle diameter can be adjusted appropriately by the amount of mixed materials and spindle speed. Generally, the lower the amount of mixed materials is, the higher the speed is, the smaller the particle size is, and vice versa. this machine is especially suitable for granulating light and fine powder materials. The finer the basic particle, the higher the sphericity and the better the quality.
5.Drying /cooling process The drying process is an indispensable and important process in the pig manure bio organic fertilizer production line and npk compound fertilizer production line, which directly affects the output, quality and energy consumption. Because the moisture content of the particles after granulation is generally between 15% ~ 20%, because the fertilizer quality index of moisture content requires less than 14% , so it which needs low temperature drying treatment with rotary dryer. Drying fertilizer are transported by belt conveyor and feeding into the rotary cooler, the cooling process mainly involves the use of wind fans to feed natural air into the cooler through pipelines to cool the granules for the following rapid packing and storage.
6.Cyclone Dust Collector and gas/oil hot air stove Cyclone dust collector is a type of dust removal device. which can increase the efficiency of dust removal, increase the down flow of the section, and increase the residence time of the dust-laden air in the dust collector, creating more separation opportunities for dust. The gas/oil hot air stove, in the drying process and the wet granulation process, which provides the necessary heat source for the drier system in the whole pig manure organic fertilizer production line with energy-saving and high-speed.
7. Rotary screener Granules were screened after cooling, and the large particles of materials are crushed by chain crusher were transported into granulator with the sifted powder by the return belt for re-granulation, and the finished products enter the coating machine and automatic packaging system for packaging. 8.Automatic packing machine
Granules packing machine is used for the quantitative packing of fertilizer granules. It consists of automatic weighing and packing machine, conveyor, sealing machine and feeder, high weighing accuracy, convenient operation. Packed fertilizer will be stored for sale.
Due to environmental pressure, more and more pig farms are trying to change the passive situation.Practice has proved that bio organic fertilizer production from pig manure for standarding farms is a relatively effective harmless treatment and resource utilization. pig manure bio organic fertilizer production line also can produce other livestock manure, like cow manure, chicken manure and other organic waste.
