Features of three cylinder rotary dryer
1.The overall size of the three cylinder rotary dryer is reduced by more than 30% compared to ordinary single-cylinder rotary dryers, thereby reducing external heat loss.
2.The thermal efficiency of the self-insulating dryer is as high as 80% (compared to only 35% for the ordinary rotary dryer), and the thermal efficiency is 45% higher.
3.Due to the compact installation, the floor space is reduced by 50%, and the infrastructure cost is reduced by 60%.
4.The temperature of the finished product after drying is about 60-70 degrees, so that it does not need an additional cooler for cooling.
5.The three cylinder structure of the drying drum increases the contact area between the wet material and the hot air, which reduces the drying time by 48-80% compared with the traditional solution, and the moisture evaporation rate can reach 120-180 kg/m3, and the fuel consumption is reduced by 48-80%. The consumption is 6-8 kg/ton.
6.The drying of the material is not only carried out by the hot air flow, but also carried out by the infrared radiation of the heated metal inside, which improves the heat utilization rate of the whole dryer.
7.The overall size of the dryer is reduced by more than 30% compared to ordinary single-cylinder dryers, thereby reducing external heat loss.
8.The thermal efficiency of the self-insulating dryer is as high as 80% (compared to only 35% for the ordinary rotary dryer), and the thermal efficiency is 45% higher.
9.Due to the compact installation, the floor space is reduced by 50% and the infrastructure cost is reduced by 60%.
10.The temperature of the finished product after drying is about 60-70 degrees, so that it does not need an additional cooler for cooling.
11.The exhaust temperature is low, and the life of the dust filter bag is extended by 2 times.
12. The desired final humidity can be easily adjusted according to user requirements.
Working principle of three cylinder rotary dryer
The material enters the dryer inner drum of the dryer from the feeding device to realize downstream drying. The material is continuously lifted up and scattered by the inner lifting plate and travels in a spiral shape to realize heat exchange, while the material moves to the other end of the inner drum then enters the middle drum, and the material is continuously and repeatedly raised in the middle drum, in the way of two steps forward and one step backward, the material in the middle drum fully absorbs the heat emitted by the inner drum and absorbs the heat of the middle drum at the same time, the drying time is prolonged, and the material reaches the best drying state at this time. The material travels to the other end of the middle drum and then falls into the outer drum. The material travels in a rectangular multi-loop way in the outer drum. The material that achieves the drying effect quickly travels and discharges the drum under the action of hot air, and the wet material that has not reached the drying effect cannot travel quickly due to its own weight, and the material is fully dried in this rectangular lifting plates, thereby completing the drying purpose.
