Introduction of Rotary Drum Dryer rotary drum dryer in fertilizer equipmentis mainly used in compound fertilizer and organic fertilizer production to dry some moisture of fertilizer,and can also be used for other materials,like chicken manure drying,cow manure drying,
pig manure drying and sand drying,city sludge drying and so on.the drum dryer advantages are reasonable design,
reliable performance,and high heat efficiency,convenient operation and maintenance and so on.
Working Principle of Rotary Drum Dryer
Materials are sent to the hopper of compound fertilizer dryer by belt conveyor or bucket elevator.
The barrel of compound fertilizer dryer is installed with a angle. raw materials enter into the barrel
from the higher side,and hot air enters into the barrel from the lower side, then materials and hot
air will mix together. the moisture will be evaporated by the high temperature of the hot air.
the materials go to the lower side when the barrel rotates.Lifters on the inner side of the barrel lift
materials up and down which makes materials and hot air mix completely.So drying efficiency is improved
