1.After the organic fertilizer is produced by the second fermentation according to the above steps,the organic fertilizer will be piled up for a second time for fermentation,and the temperature will be reduced to about 40 ℃ for 15-20 days.Sometimes,when making organic fertilizer,it also needs to use the fermentation compost turner machine in organic fertilizer production line.The bacterial agent with the functions of phosphorus,potassium,nitrogen fixation and underground pest control will be evenly added to the fermented organic fertilizer in the proportion of 1:500.
2.The standard of bio organic fertilizer can be reached 7days after adding functional bactrialo evenly and adding functional bacteria and fermented organic fertilizer evenly to the organic fertilizer stack for fermentation.
3.The fermented bio organic fertilizer is screened and put into storage.
4.Granulation will be processed functional pure bio organic fertilizer granulation.According to different raw materials,we choose pelletilizer,disc pelletilizer,roller press granulator machine which it also to be used in npk fertilizer manufacturing process to make npk,compound fertilizer.
5.The moisture content of the particles just made by drying ,cooling and packaging is relatively large.It is necessary to dry the moisture to below 20% of the organic fertilizer standard.When selecting the dryer,the bio organic fertilizer should be selected at low temperature(the temperature is lower than 80 ℃ )and the dried particle organic fertilizer should be directly packaged after being cooled by the cooler.
In npk fertilizer prodution line, it is to be equipped with the fermentation compost turner machine to ferment the raw materials that the series fertilizer machine can use the simple compost turner machine to ferment the raw materials. And then it is to be equipped with the fertilizer crusher machine and fertilizer mixer machine and fertilizer crusher machine to deal with the raw materials. We can use the chain crusher machine, and the horizontal mixer machine to deal with the organic raw materials. Next, when producing the organic fertilizer granulator, the fertilizer granulator machine
are necessary to be equipped in the npk manufacturing process
