2.5×7 High Efficiency Industrial Sand Drying Machine / Three - Drum Dryer for Sand Coal
Application of Sand Dryer
The three-cylinder dryer can be used to dry coal, oil, gas and other various fuels, and it can dry lump, particle shape,and powder and many other kinds of materials accord with a policy to create an environment friendly, resource conservation-oriented society, and is an environmental protection energy-saving products which is the replacement of traditional drying equipment.
Structure of Sand Dryer
Sand Dryer is made up of three different diameter homocentric cylinder according to the certain mathematical relationship and cylinder structure then combinated by embedded with each another. Because of the three-cylinder dryer special structure, the length of the cylinder body is the single cylinder dryer one third. Base area than the single cylinder dryer save 65%, the basic investment corresponding reduced. This dryer adopts roller and belt friction transmission which has a low power transmission and reduces the noise of equipment. Sealing system uses a micro touch technology, has a better sealing effect, reduces the dust pollution.
Advantages of Sand Dryer
1. With high technical content, cylinder self insulation, thermal efficiency is as high as 80% (single cylinder dryer is only 35 percent), thermal efficiency than single cylinder drying saves coal 68 percent, yields 100%.
2. Compared to single cylinder dryer the machine length shortens 60%, in favour of process arrangement. Reduces workshop covered area, saves the project investment by around 40%. Covers an area of about 20m2.
3. Heat-resisting wear-resisting alloy steel plate, four times than ordinary steel wear-resisting. Long service life and easy maintenance.
4. High thermal efficiency, outside shell temperature below 60 °C (single cylinder dryer outside shell temperature as high as 150°C), output of low temperature, discharging temperature below 60 °C.
5. Output of low temperature, be helpful for dust removal equipment to use a long time, can be directly supporting air tank pulse bag filter.
6. Construction investment reduces 50% or so, power consumption reduces 60%.
7. Don't need sizes of gear-driving, and adopts roller rotation.
8. Hot air stove can supporting fluidezed bed, spray stove, hands burned furnace, also used in fuel and gas type, can bake the below 20 mm pieces of materials, aggregates, powder material.
