Organic fertilizer is becoming very popular and acceptable, then how to establish a valuable organic fertilizer production plant? Our organic fertilizer production line mainly includes: organic fertilizer mixer, organic fertilizer mixing granulator machine or organic fertiizer pan/disc granulator machine, fertilizer rotary dryer, fertilizer rotary cooler, rotary drum coating machine,chain crusher, rotary screening machine, packaging machine, belt conveyor and other accessories.
Production Process of Organic Fertilizer Production Line
organic compost turner machineis used for fermenting and composting organic waste, such as animals & fowls manure, sludge waste, sugar filter mud, oil seed residues and straw sawdust etc. Materials can be mixed and fermented in the trough for 7-10 days. Temperature should be in 60-70℃ and moisture content should be between 40-50%.
after fermented, the materials are mixed evenly together in our mixer machine to improve fertilizer nutrient distribution uniformity and the greatest fertilizer nutrient use efficiency, which is also helpful for further granulating. The horizontal mixer machine is also suitable for feed, concentrated feed and additive premix mixing.
after even mixed, the materials are transported into organic fertilizer granulator machine for granulation. The granules shape of organic fertilizer granulated by fertilizer pellet mill is round ball shape. Usually, a fertilizer polishing machine, which is designed based on flat die extrusion granulator, is used to polish the granules into ball shape with easy operation.
after granulation, the granules will be conveyed to fertilizer dryer machine. The aim of drying process is to reduce granules moisture, to increase fertilizer strength, convenient to store. After drying, the granules temperature is 60-80℃. due to too much heat, caking of fertilizer granules is easy to occur, so they need to be cooled in rotary drum cooler to decrease the temperature, After cooling, the granules temperature is 20-40℃, easier to storage and transportation.
Unqualified fertilizers are screened out to re-granulate, while qualified ones are coated to increase the brightness and roundness of finished products, and then packaged for further storage.
