1. The special requirements of composting technology are realized, such as crushing raw materials, realizing quantitative displacement of raw materials or giving certain shape to raw materials pile.
  2. Improve the permeability of the raw material pile: the turning system can process the material into small lumps, making the material pile fluffy and forming appropriate porosity.
  3. Mixing function in raw material conditioning: in fertilizer making, some auxiliary materials need to be added in order to adjust the carbon nitrogen ratio, water content and pH value of raw materials. The agitator can be used to mix the main raw materials roughly stacked together according to the proportion with various auxiliary materials, so as to achieve the purpose of quenching and tempering.
  4. Adjust the moisture content of raw material pile: the suitable moisture content of raw material fermentation is about 55%, and the moisture standard of finished organic fertilizer is below 20%. The forced steam emission will be formed when the material is turned by thecomposting machine, which can reduce the water content and improve the fertilizer production efficiency.
  5. Adjust the temperature of the raw material windrow: during the operation of the compost turner, the raw material pellets and air are fully contacted and mixed. When a large amount of fresh air is kept in the windrow, the aerobic microorganisms will become active, thus producing fermentation heat and increasing the stack temperature; when the temperature is high, fresh air can be added to reduce the stack temperature. The formation of medium temperature to high temperature and then to medium temperature to high temperature, such a cycle state, all kinds of beneficial microorganisms grow and reproduce in their adaptive temperature range.
