Introduction of three key branch systems of organic fertilizer production line


The three key branch systems of the organic fertilizer production process are granulation forming system, ingredient crushing and mixing system, screening and recycling system.
1. Granulation forming system
The wet-process organic fertilizer granulator is used to granulate various organic matter after fermentation, breaking through the conventional organic matter granulation process. There is no need to dry and crush the raw materials before granulation. The spherical particles can be processed directly by the ingredients, which can save A lot of energy. The particle shape is spherical, the sphericity is greater than or equal to 0.7, the particle size is generally between 0.3-3 mm, and the granulation rate is greater than or equal to 90%. It is suitable for the granulation of light and fine powder materials. Typical application materials: chicken manure , Pig dung, cow dung, carbon black, clay, kaolin, etc.

2. Ingredients, crushing and mixing system
The function of this system is to pulverize, proportion and mix the composted materials, NPK inorganic fertilizers and other additives in proportion. Based on many years of experience, the recommendations for organic fertilizer machine are as follows: using a vertical grinder to crush livestock and poultry manure compost is not easy to stick to the wall and not easy to block, and the multi-layer turbulent chain hammer structure improves the crushing performance; the continuous automatic batching system is suitable for organic fertilizer equipment Dynamic metering of raw materials and batching control; the mixing operation is equipped with a double-shaft continuous mixer, which has good sealing performance, and the wet and sticky materials are not easy to adhere to the root of the mixing shaft.
3. Screening and recycling system
The granular materials output from the granulation forming system have obvious differences in particle size and need to be sieved and classified. The selected rotary screening machine requires low vibration, low noise, convenient screen change, and is equipped with a screen surface cleaning device. It is recommended to be equipped with an automatic material return system to screen the unqualified large and small particles, convey them through the belt elevator, and send them to the granulator to continue the granulation after re-pulverization, which helps to improve the continuous operation capacity of the organic fertilizer production line.
