There are two common composting methods in fertilizer production process
Date:2020/04/29
Composting and fermentation of fertilizer production process is a process to realize the harmless of organic materials. There are two types of commonly used processes, i.e. stacking process and tank process.
1. Strip and stack fermentation
Stacking composting process is a common aerobic fermentation system, which can decompose raw materials in aerobic condition by stacking them in long strips or stacking.
① Heap shape. The bottom width of the pile is controlled between 120-300cm (or determined according to the width of the crawler compost windrow turner), and the pile height is controlled between 80-200cm, with 120cm as the most appropriate; the length is unlimited. The spacing of each stack is about 80-100cm;
② Composting equipment. It is mainly a stacker tripper: the technical parameters of the main equipment are the maximum allowable stacker height of 200cm, stacker width of 300cm, forward / backward speed of 5-15m / min, and production capacity of not less than 600m3 / h.
Tank fermentation is a kind of aerobic composting fermentation technology, which combines controlled ventilation and regular turning of piles.
① The size of fermentation tank is usually L × w × H = (60 ~ 100) m × (4 ~ 9) m × (1.5 ~ 2) M. guide rails are laid on the upper part of the tank wall for the convenience of the composter walking; aeration system is laid on the bottom of the tank to ventilate and oxygenate the fermentation materials in the tank, which is mainly composed of high-pressure fans and ventilation pipes.
② The tank type compost turning machine agitates the materials evenly by mechanical agitation, promotes the heat and moisture volatilization, and displaces the materials slowly in the tank. Common organic fertilizer machines include chain plate and agitator, mainly composed of traveling chassis, chain plate (agitator), hydraulic lifting part, transmission part and electric control part.
