Three-cylinder dryer Among the series of wet material drying equipment, the rotary three-cylinder dryer is an improved high-efficiency and energy-saving product based on the single-cylinder rotary dryer. After the application of many enterprises and many industries, good results have been achieved. The rotary three-cylinder dryer improves the internal structure of the original single-cylinder dryer, increases the pre-drying of the wet material before entering the machine and extends the drying time of the wet material in the machine, plus sealing, heat preservation and reasonable supporting measures. With advanced technology, reasonable operating parameters, simple and feasible operation, it is widely used in material drying work in various industries.

Product Advantage

Product advantages

1. The supporting roller is used for supporting, the large and small gear transmission is eliminated, and the supporting roller transmission is replaced, which makes the equipment installation more convenient, simpler to operate, more reliable in operation, and higher in operation rate.

2. The external surface area of the three-cylinder dryer is more than 30% less than that of the single-cylinder rotary dryer, and the outer cylinder has the effect of heat preservation and heat insulation on the inner cylinder. The surface temperature of the outer cylinder is low, and the heat loss is small. It is efficient and energy-saving. , Greatly improving the working environment and working conditions.

3. A variety of lifting board designs, the organic combination of the angled lifting board and the 4D lifting board, makes the material and hot flue gas exchange more fully, and the drying efficiency is higher.

4. Use frequency conversion to adjust the speed of the barrel, and use the appropriate speed according to the water content and output requirements to ensure that the needs of the next process are met. The automatic temperature monitoring system makes the operation more convenient.

Working Principle

Structure principle

The material enters the inner layer of the rotary drum from the feeding device to achieve downstream drying. The material is continuously picked up and scattered under the inner layer of the copy plate to achieve heat exchange in a spiral manner. The material moves to the other end of the inner layer and enters the middle layer. In countercurrent drying, the material is continuously raised in the middle layer repeatedly, in a two-step forward and one-step travel mode.

The material in the middle layer not only fully absorbs the heat emitted by the inner drum, but also absorbs the heat of the middle drum, and at the same time prolongs the drying time, the material reaches a good drying state here. The material travels to the other end of the middle layer and falls into the outer layer. The material travels in the outer drum in a rectangular multi-loop manner. The material that achieves the drying effect quickly travels out of the drum under the action of hot air. The wet material that does not achieve the drying effect cannot be fast due to its own weight. As it progresses, the materials are fully dried in this rectangular copy board, thus achieving the purpose of drying.
