Functions of Compost Turners

Composting is a process in which the manure collected in the fecal canal of the farm is dehydrated by a solid-liquid separator, and then mixed with crop straw or sawdust according to a certain proportion to adjust the carbon nitrogen ratio, and add microbial strains. Through the up and down tossing of the composting machine, aerobic fermentation is carried out to form organic fertilizer and soil amendment, so as to achieve the purpose of harmless, reduction and resource utilization.

The emergence of the compost turning equipment is gradually replacing manual material turning. It has the following five functions in composting.

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 raw material pile: the turning system can process the materials into small lumps, and make the thick, elastic and dense raw material pile become fluffy and form appropriate porosity.

3. Mixing function in raw material conditioning: in fertilizer making process, 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%. In fermentation, the consumption of raw materials by microorganisms will make water lose carrier and free out, and biochemical reaction will generate new water. Therefore, in addition to evaporation formed by heat conduction, forced steam emission will be formed when the material is turned by the compost turner, which can reduce the water content in time with the process of fertilizer production.

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 pile, the aerobic microorganisms will become active, thus producing fermentation heat and increasing the windrow temperature; when the temperature is high, fresh air can be added to reduce it.
