Therotary dryeris a type of industrialdryeremployed to reduce or minimizer the liquid moisture content of the material it is handling by bringing into direct/indirect contact with a heated gas. Thedryeris made up of a large,rotatingcylindrical tube, usually supported by concrete columns or steel beams.
Dec 03, 2015·Rotary dryersare a highly efficient industrialdryingoption for bulk solids. They are often chosen for their robust processing capabilities and their ability to produce uniform results despite variance in feedstock.Rotary dryerswork by tumbling material in arotatingdrum in the presence of adrying…
Directheatrotary driersare used to lower the moisture content of materials passing through thedryer. Materials are directly heated using heat from a combustion process; the fuel used is typically gas although pulverisedcoal,light fuel oil or waste process gasses could also be used.
Directand indirect-firedrotary dryersare used in a variety of industrial settings to dry bulk solids. While the two are both comprised of a rotating drum and function to reduce a material’s moisture, several differences betweendirectand indirectdryersexist:
Rotary dryer, also calledrotary drum dryer,is a kind of heating device, making the material reach a certaindryingdegree or certain moisture content. Rotary dryer machine is widely suitable for drying slag, limestone,coalpowder, clayand other materials in such industries as building materials, metallurgy, chemical industry, cement, etc.
DIRECT ROTARY DRYERS COOLERThe material to be dried/cooled comes in direct contact with thedrying/coolingmedia. The dryer comprises of arotatingshell supported on rollers/tyres and driven by means of suitable drive arrangement.

Rotary Dryer– Arotary dryercan be used, however, the generation of fines is high. These are vey low RPMdryersand hence the drying is inconsistent i.e. the driedcoaldoes not have uniform moisture. Tornesh or FlashDryer– Maximum particle size limited to 6 mm. Thoughdryersare cheap, the crushing ofcoalto lower sizes cannot be avoided.

Therotary dryerdesign consists principally of a rotating cylinder that is enclosed in a furnace along its active length. With heat transfer indirect and through the cylinder wall, the gas velocities within an indirectdryerare low as compared to adirectheatdryer, and correspondingly, the off-gas system is smaller and more economical.

Adopts downstream drying method, the flue gas, and wet material into the drying machine by one side of thedryer, it can take advantage of the high-temperature flue gas to obtain high evaporation strength, the low outlet temperature of thedryer, with high thermal ...
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.
