1.High a thermal efficiency.
2.Remarkable energy saving and consumption.
3.Little engineering investment.
4.Little thermal loss.

1 Three cylinder drying machine equipment investment is 1/6 of the imported products made of alloy steel wear-resistant 3-4 times than ordinary steel plate.
2 The material initial moisture is 15% final moisture to ensure the following 0.5-1%widely used in cement plant slag powder and dry mixed mortar production line product of choice.
3 Three cylinder drying machines’ thermal efficiency can be amount to as high as 80% (traditional single cylinder drying machine thermal efficiency is only 32%) which can improve the thermal efficiency to 48%.
4 The fuel can be adapted to anthracite bituminous coal coal gangue oil steam can bake 20-40mm block granular powdery materials.
5 Three cylinder dryer reduce the area of about 50% than single cylinder drying machine civil investment decreases about 50%.
6 Our dryers are no leakage phenomenon it can completely solve the sealing problems and also can be installed within 2 hours.
7 It cancan easily control the final moisture index according to the customers’needs.
8 The material temperature is less than 50 degrees which can be directly into the database without the need for cooling roof .
9 Three cylinder drying machine barrel temperature is only 60 degrees the exhaust gas temperature is < 100 degrees dust removal equipment bag for a long time is more than 2 times which is water vapor.
10The coal consumption of three cylinder dryers is 1/3 of single cylinder drying machine saving 40%. Tons of standard coal consumption < 9 kg small model dryers for annual coal is the 50-100 million a bigger model dryers is 100-200 million .

Taida three cylinder dryers are newly developed for dry mixed mortar, sand, cement plant, coal gangue, slag, clay mixture, fly ash, gypsum, iron powder as the raw material, widely used in building materials, chemical industry, foundry industry. Three cylinder dryers improved the internal structure of single cylinder drying machine, coupled with the sealed equipments, moisture and reasonable measures, the production capability increases by 50-80% with other dryers, volumetric evaporation intensity up to 120-180kg/m3, the standard coal consumption is only 6-8kg/t. Its characteristics are advanced technology, reasonable parameters, simple and feasible operation.

The thermal efficiency of double-canister is high, and energy-saving effect is obvious. Thermal efficiency exceeds 50% of traditional single canister dryer via test, coal saving is obvious after using it.

The principle of dryer is scientific, rational, high efficient and energy-saving. The thermal exchange of material in the form of thermal current radiation, convection and conduct in inner canister, while in outer canister, the thermal exchange in the form of conduct and convection.

The length is less than before, which is good for technical layout, the entire length is shorter than single-canister dryer about 50%, so which retrench the workshop floor area and project investment, and is more applicable for technical transformation of old workshop.

The equipment adopts downstream drying technology of material and thermal air current, has wide applicable scope, which is useful for drying of clay, coal, slag and iron powder and kinds of raw material, also for bulk material in chemical industry and metallurgy industry and etc.

Its entire structure is compact and horizontal layout, and adopts supporting wheel transmission instead of big and small gear transmission, which is convenient for installation, simple for operation, reliable for running and has higher running rate.

Its outer surface area is smaller than single-canister rotating dryer about 50%, and the outer canister can keep thermal insulation for inner canister, the temperature of outer canister is low and the thermal loss is small, the working environment and condition is improved while it saves energy.

Kinds of tossing plate and the combining of angle and gammadia tossing plate make the exchange of material and heat gas more fully, so reduce the generation of wind tunnel in canister of dryer.
