2. The traditional compound fertilizer production line adopts the slurry method or the humidified pellet method, which requires granules to be introduced before the granulation. In the fertilizer manufacturing process, a large amount of energy is consumed to dry the moisture, which results in a large amount of waste gas and waste water. , Waste residue, polluting the environment. Extrusion granulation of a compound fertilizer production line is the extrusion of materials by external force. No steam is required during the granulation process, which can save investment in boiler construction and coal production costs. The compound fertilizer production line has no moisture introduction and no drying process in the entire production process, eliminating the large and expensive dryer in the traditional compound fertilizer production line device, and can use the fuel and drying equipment for drying. The power consumption is saved, so the process of this compound fertilizer production line meets the needs of today's energy-saving society.

3. In the traditional 
NPK fertilizer production line, during the production process, the hot-air stove and preheated air are used to dry the materials. The hot-air stove burns coal to generate a certain amount of sulfur dioxide gas, which pollutes the atmosphere, and the fertilizer does not need to be burned during the entire production process. Coal not only saves energy, but also does not produce sulfur dioxide gas. The traditional compound fertilizer production line will produce a large amount of dust and wastewater in the process of crushing, mixing, drying, cooling, and screening of materials, which is a clean production process.

4. The fertilizer is less affected by the external environment (such as temperature and humidity) during the production process, the operation flexibility is large, and the process formula is flexible.

5. The compound fertilizer production line has a high ball formation rate, low moisture content, high particle strength, less system return, and less agglomeration in the production process, which has better economic benefits.

compost turner machine


The Double-screws Turning Machine comprises a traverse device, a traveling device and a tumbling device, wherein the tumbling device comprises two reducers fixed to the frame, a screw shaft connected to the respective reducer via a coupling member and fixed with a spiral blade. When the device is walking on a specific track, the screw shaft will no longer work, and the screw shaft will automatically rotate to move against the work when walking to the effective work surface. The fermentation rate is increased, the compost is rapidly decomposed, the odor is prevented from being generated, and the fermentation time is shortened.

Double-screws Turning Machine performance characteristics:

1. Fully stir the doping to make the material meet the granulation demand quickly.

2. Due to the large stacking force, the material is supplemented with more fresh air, which helps the aerobic microbial fermentation to heat up, and constitutes a process of high-temperature exchange, which helps all kinds of beneficial micro-bacteria to develop and multiply in the temperature range where it adapts.

3. The turner system can process the material into small clumps, making the thick and dense material pile loose and elastic, and forming a suitable porosity.

4. After the raw materials are turned over and fermented, there is certain water content. The consumption of raw materials by a large amount of microorganisms generated after turning over the piles will also release the water in the carrier. Therefore, as the fertilizer process reduces water, in addition to the evaporation of the heat transfer composition, the turning machine flips the raw materials to form a forced water vapor volatilization.

5. Achieve special requirements for the composting process. For example, the breaking of the raw material, the shape of the raw material pile or the quantitative shift of the raw material is achieved. As one of the important equipment in the fermentation equipment and organic fertilizer production process, the turner has been at the forefront of the development of the times, making great contributions to the organic fertilizer production line and  biofertilizer project.
