rotary drum dryer seals

Mar 21, 2019· Insulation of therotary drum dryer drum. Thedrumof therotary drum dryeris generally made of steel plate of 10 to 16 mm thick, and the length of thedrumis generally more than 12 m. The temperature of the inlet wind is about 800 °C, the temperature of the outlet wind is about 100 °C, and the heat loss of thedrumis about 8%.

Working Principle: Therotary dryeris mainly composed of a rotating body, a lifting plate, a transmission device, a supporting device and a sealing ring. Thedryeris a cylinder that is slightly inclined from the horizontal direction. The material is added from the higher end，The high-temperature heat source and the material parallelly flow or counter-flow into the cylinder.

Asealis essential at each end of arotaryunit to prevent ambient air from entering the process. Air leakage can have varying effects on different processes and aleaky sealmay reduce efficiency, create unsafe or unstable conditions.Sealsare damaged most by overheating or by physical abuse.

Drum sealsminimize air leakage in exhaust system; ... In any fuel application therotary dryeris designed to meet optimal fuel firing rate for efficiency. BMS(burner management system) controls start-up sequence, firing rate,dryer& bag house temperature limit, auto-temp-tracking, flame monitoring as well as blower-exhaust fan interlock.
