Process steps of using livestock manure to make round granular organic fertilizer

Update time : 2022-02-25 Publisher:Tongda

1. Fermentation and decomposing collect livestock and poultry manure, mix it with straw, hay, etc. to control the water content to about 65%, and then transport it to the fermentation tank, sprinkle with aerobic fermentation bacteria, and fully mix it with a hydraulic tank turner. Then let it ferment, and use a turning machine to turn the material and cool it down during the fermentation.


2. Material crushing will pass the material that has been decomposed at high temperature and go through the processing of organic fertilizer crusher equipment. The organic fertilizer wet material pulverizer is a professional pulverizing equipment for pulverizing high-humidity and multi-fiber materials. Using high-speed rotating chain, crushed fiber with good particle size.

3. Mix and stir to add trace elements, auxiliary materials, humic acid, clay, etc. for mixing and stirring. The vertical mixer is used for fast mixing speed and good uniformity. It can mix viscous materials with 30% of the liquid added. When working, there are two rotors with opposite rotating blades to stir in the middle. The bottom door is used to discharge the material quickly and the residual amount is small.

4. Forming and granulation The material is granulated by organic fertilizer disc granulator, organic fertilizer stirring tooth granulator or new type stirring tooth drum three-combination granulator.

5. The drum drying organic fertilizer dryer further removes the moisture from the granulated granules to meet the standard requirements of the moisture content of organic fertilizers.

6. The drum cooling uses a cooler to cool the dried granular materials, which is helpful for the storage and quality of the particles.

7. Screening and feeding system Due to the granular material output by the granulating and forming system, the particle size is different, and it needs to be screened and classified. The selected drum type screening machine requires small vibration, low noise, convenient screen replacement, and is equipped with a screen surface cleaning device.

8. Particle coating equipment The coating machine is composed of a screw conveyor, a stirring tank, an oil pump, a main engine, etc. It uses powder or liquid coating process. It can effectively prevent the agglomeration of fertilizers, and the main body is lined with polypropylene or acid-resistant stainless steel.

9. Packaging equipment The granular materials are packaged and entered into the finished product warehouse through the conveying equipment. Granular materials are quantitatively weighed and packaged through automatic packaging scales.
