Features of drum granulation process:
Steam is introduced into the material layer of the drum granulation(https://www.hqhifertilizermachine.com/solution/rotary-drum-granulation-production-line.html) to improve the temperature of the granulation material, dissolve the salt of the granulation material, achieve the high liquid volume under the low moisture content to meet the liquid volume required for the granulation of the material, and reduce the evaporation water volume of the drying process.
The inner wall of the drum granulation is lined with a number of soft rubber plates or polypropylene plates, and the corresponding positions of the cylinder are provided with air holes. When the inner lining is transferred from the bottom to the top at the same time with the cylinder, the inner lining will sag due to the relationship of self weight, so that the materials attached to the inner lining will fall down due to the gravity, so as to achieve the function of automatic cleaning of the materials.
During the operation of the rotary drum granulation fertilizer production line, the operator can observe the balling of materials at any time, and take corresponding measures in time as required to ensure the normal operation of the system.

In the organic fertilizer production line(https://www.hqhifertilizermachine.com/solution/organic-fertilizer-production-line.html), the raw material pellets are fully contacted and assimilated with the air, and a large amount of novel air can be contained in the pile, which helps aerobic microorganisms to actively produce fermentation heat and the temperature of the heap increases; when the temperature is high, the novel air is filled The temperature of the heap can be lowered, and the water can be reduced in real time with the process of fertilizer production. In addition to the evaporation formed by heat conduction, the turning of the material by the heap turning machine will form a mandatory water vapor. Equipped with a tooth extraction pressure lifting system, as one of the main equipment in the fermentation equipment and organic fertilizer production process, the stacker has always been at the forefront of the growth of the times, and has made great contributions to the production of organic fertilizer. For example, the crushing of raw materials, giving the necessary shape of the raw material pile or realizing quantitative displacement of raw materials, etc., are mainly used for the application of organic fertilizer production lines in fertilizer equipment, which can be said to have reached a state of popularization.

The process of organic fertilizer production line: raw material selection (animal manure, etc.) - > drying and sterilization - > ingredient mixing - > granulation - > cooling and screening - > metering and sealing - > warehousing of finished products. The complete set of equipment is mainly composed of fermentation system, dryer, deodorant and dust remover, pulverizer, batching system, mixer, fertilizer granulator(https://www.fertilizermachine-solution.com/fertilizer-granulator-machine-series/) and finished product packaging machine; (harmless treatment of livestock and poultry manure, etc.) fermentation system includes: feed conveyor, biological deodorant, mixer, exclusive dumper, oxygen supply system and automatic control system. The construction scale is generally 30000-250000 tons per year. Local resources, market capacity and market coverage radius should be considered comprehensively. Generally, 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 plants is 50000-100000 tons, and that of large plants is 100000-300000 tons. The investment scale and product scheme design need to be formulated according to the following conditions: characteristics of raw material resources, local soil conditions, local planting structure and main crop varieties, plant site conditions, production automation, etc.
