The Role of the Trough Tumbler

1. The mixing function of the raw material conditioning of the trough tumbler. In the process of making fertilizer, some auxiliary materials are added in order to adjust the C/N ratio, pH value and water content of raw materials. The main raw materials and various auxiliary materials, which are roughly stacked together in proportion, are stirred with the tumbler and mixed with each other to achieve the purpose of modulation.

2. Trough tumbler to adjust the temperature. When the trough type tumbler is running, the raw material pellets are mixed with air in full contact, and a large amount of fresh air can be saved in the pile, which helps aerobic microorganisms produce fermentation heat and increase the pile temperature. When the temperature is high, supplemental fresh air can reduce the reactor temperature. The formation of medium-high temperature - medium-high temperature - high temperature alternating state, a variety of beneficial microorganisms in its adaptation to the temperature range to grow and reproduce.

3. Trough turning machine to improve the permeability. Turning system can process the material into small pieces, make the thick and dense pile fluffy and elastic, and form a suitable porosity.

4. Trough tumbler can adjust the moisture content. The suitable moisture of raw materials for fermentation is about 55%, and the moisture standard of finished organic fertilizer is below 20%. During the fermentation process, biochemical reactions will generate new water, and the consumption of raw materials by microorganisms will also make water lose its carrier and free. So as the fertilizer is made, the moisture will be reduced in time. In addition to evaporation caused by heat conduction, the raw materials coming out of the trough tiller will form forced water vapor emission.

5. Trough tumbler realizes the special requirements of the composting process. Such as crushing raw materials, giving a certain shape or achieving quantitative displacement of raw materials.
