Triple Pass Rotary Drum Dryer VS Single Pass Rotary Dryer
Furein Machinery is a sand dryer manufacturer with nearly 35 years of production experience, today Furein's engineers will be here to analyze the similarities and differences between triple pass rotary dryer and single pass rotary dryer for you.
Similarities between the triple pass rotary drum dryer and single pass rotary dryer:
Let's take drying sand as an example, firstly, we will talk about the same points of three return rotary drum dryer and single return rotary drum dryer:
- Both three return and single return dryers can dry wet sand with a moisture content of about 15% into dry sand.
- Their working principle is to achieve the purpose of drying sand by heating the cylinder, so that the sand is fully in contact with the hot airflow in the cylinder, taking away the moisture in the sand.
- Both three return and single return can form drying line, and at the same time configure feeding device and unloading device.
- All of them can be equipped with intelligent control system for three-return or single-return sand drying line, controlling feeding and discharging at the same time, remote control, easy to operate.
- Their fuels are all diversified, diesel, coal, natural gas, biomass pellets can be used as the dryer's fuel.
- Wide application, besides drying sand, it can also dry fly ash, sludge, sand, manure and other materials.
Differences between triple pass rotary drum dryers and single pass rotary dryers:
Let's talk about the difference between the triple pass dryer and the single pass drying machine:
1. Different structure
From the appearance of the single dryer only a cylinder, when the sand through the single return dryer, from head to tail is only a few meters long, in order to better improve efficiency, had to increase the length of the cylinder dryer, making better drying sand.
Thriple pass rotary drum dryer is three layers of cylinder nested together, the sand with the cylinder rotation and full contact with the air, so as to take away the water content in the sand. The research and development of thriple pass drum dryer is designed for drying sand.
2. Drying effect
The length of the single pass dryer is longer, and the structure of the three-cylinder dryer is more reasonable, covers a small area, does not have the limitation of length, and is better for transportation. For the effect of drying sand, the thriple pass drum dryer is 2 times the efficiency of the single dryer. But the single pass dryer is more widely used.
Triple pass rotary drum dryer vs single pass rotary dryer, how to choose?
When choosing between a thriple pass rotary drum dryer and a single pass rotary dryer, you may want to consider these factors:
Material
- When your material is sand, fly ash, Furein Machinery strongly recommend you to choose the thriple pass dryer, which combined with the dry mortar production line, can save you space and reasonable layout of the whole production line. When you import from China, it can save a lot of sea freight and reduce the production cost.
- When your material is sludge, wood chips, grain, feces and so on, you can choose single pass rotary dryer. If you don't know how to choose, please contact the sand rotary dryer manufacturer.
Factory size
A single pass drum dryer takes up more area than a triple pass dryer because its cylinder is 2-3 times larger than a triple pass dryer.
If you have limited space, then a triple rotary dryer is a good choice.
Cost
For the same output of sand dryer, the price of thriple rotary drum dryer will be a little bit higher, but it can save you more on freight and efficiency, which makes the thriple pass dryer cost less in the long run.
