Our fertilizer cooling machine is regularly used in compound fertilizer production line, to cool fertilizers with a certain temperature and granularity. If used in combination with a dryer, our cooling machine can largely increase cooling speed, reduce labor intensity, and improve finished-product quality. Meanwhile, the drum cooling machine can further reduce materials’ water content.Additionally, our cooling machines are also applicable for cooling many other powder materials and particles.
features of drum cooling machine
1.The wet materials is sent to hopper by belt conveyor or bucket elevator.
2.the drum cooling machine cylinder is a rotary cylinder of a slightly slop with the horizontal line.
3.The materials are fed from the higher side while the heat-carrying agent enters from the lower side,
which forms countercurrent contact with materials.
4.With the rotating of cylinder, the materials move to the lower end because of its gravity.
Wet materials in the cylinder body directly or indirectly obtains the heat from the heat-carrying agent and become drier.
5.There is shoveling plates in the cylinder body. It is used for putting the materials up and down,
so the contact surface between materials and flow become bigger, improve cooling rate and pushing
6.Users can use the cyclone de-dust device to remove the dust in the tail gas after cooling.
working pricinple of drum cooling machine
Working principle of the cooling machine Material to be dried enters the drier, and as the drum cooling machine rotates, the material is lifted up by a series of internal fins lining the inner wall of the drum cooling machine. When the material gets high enough to roll back off the fins, it falls back down to the bottom of the cooling fertilizer machine, passing through the hot gas stream as it falls. This gas stream can either be moving toward the discharge end from the feed end (known as co-current flow), or toward the feed end from the discharge end (known as counter-current flow). The gas stream can be made up of a mixture of air and combustion gases from a burner, in which case the dryer is called a direct heated dryer. Alternatively, the gas stream may consist of air or another (sometimes inert) gas that is preheated. When the gas stream is preheated by some means where burner combustion gases do not enter the dryer, the dryer known as an indirect-heated type. Often, indirect heated dryers are used when product contamination is a concern.
