The equipment configuration of the organic fertilizer production line needs to be designed according to the characteristics of raw materials (such as livestock manure, straw, etc.) and the requirements of finished products (powder or granules), mainly divided into the following steps: 1 Pre processing equipment: including dehydrators (to reduce the moisture content of raw materials), crushers (to crush large pieces of raw materials), etc., to ensure the efficiency of subsequent fermentation. two Fermentation system: Tank or stack fermentation requires the use of a turner or turner to promote aerobic fermentation; Some production lines use fermentation tanks with automated temperature and humidity control. three Crushing and mixing: After fermentation, the material needs to be crushed again, and auxiliary materials (such as microbial agents and trace elements) are added through horizontal or vertical mixers to ensure uniform composition. four Granulation molding: Disc granulator, drum granulator or extrusion granulator compresses powder into particles, and different models adapt to different hardness requirements. five Drying and cooling: The rotary dryer evaporates moisture, and the cooling machine cools and shapes the particles through a fan to avoid clumping. six Screening and packaging: The vibrating screen separates qualified particles from the return material, which is then re granulated; The automatic packaging machine completes weighing and sealing. Auxiliary equipment such as belt conveyors, dust collectors (to reduce dust), and deodorization towers (to treat exhaust gases) can enhance environmental friendliness. Small and medium-sized production lines may simplify processes, while large factories require fully automated control to achieve an annual production capacity of over 10000 tons. The key is to choose the appropriate equipment combination based on the investment budget and product positioning.
