Our triple pass dryer is characterized by compact structure, reasonable layout, reliable running, high thermal efficiency, and low power consumption.

Features

With self-insulated drums, the triple pass dryer has thermal efficiency as high as 80% while the thermal efficiency of single drum drying machine is only 35%. Compared with the single drum product, the triple drum drying machine saves coal by 68% and its output is increased by 100%.
The length of the triple drum rotary drying machine is only 40% of that of the single drum product, which is conducive to process layout. This also reduces plant construction area and saves 40% of the project investment. The floor area of this triple pass dryer is approximately 20 square meters.
Our product adopts the heat-resistant, wear-resistant alloy steel plate which is four time more wear-resistant than ordinary steel plate, so it has long service life.
Temperature of the material discharged from the triple pass dryer is lower than 60℃ while the discharging material from the single drum drying machine is 150℃ in temperature. The low outlet temperature helps to extend the service time of the dust removal equipment. An air box pulse bag type dust remover can be used.
The hot blast stove can be used in conjunction with the fluidized bed furnace, coal stove, and gas furnace.
