The role of organic fertilizer dryer in fertilizer production line

The role of organic fertilizer dryer is a lot, its operation is also very difficult, many people in the operation of organic fertilizer dryer will appear misunderstanding, which leads to the use of poor effect. When operating the organic fertilizer dryer, it is best to first understand the working principle of the organic fertilizer dryer, and then the correct operation.
Organic fertilizer dryer is a vital organic fertilizer equipment in organic fertilizer production line. The dryer is a problem of water vapor return to the material after the temperature of the system decreases in the same direction. In the drying process, the hot gas flow moves forward from the tail, fully contacts with the material, and makes full use of the heat transfer through heat conduction, convection, and radiation.

A section of secondary granulation area is set at the front of the organic fertilizer dryer, in which the materials can realize secondary granulation. Then the materials are lifted up through the lifting plate and fully dried. The wet hot air is extracted from the tail of the dryer through the exhaust fan through the pipeline and enters the sedimentation chamber for sedimentation. The tail gas is sprayed to reduce dust through the washing tower after sedimentation. The spray water is pumped out by the water pump for recycling. After secondary dust reduction treatment, the tail gas is discharged into the atmosphere through the chimney.
The dried materials are sent to the cooler through the belt conveyor for cooling. In the cooling process, the natural air is sent to the cooler through the pipeline by the fan to cool the materials. The wind direction in the cooler is countercurrent. The tail gas pumped into the sedimentation chamber through the fan and pipeline is treated as the drying tail gas and discharged into the atmosphere.
The cooled materials enter the screening. After crushing, the large particle materials and the screened powder enter the return belt and are transported to the granulator for re granulation. The finished products enter the automatic packaging system for packaging.
