Rotary drum dryer

  Rotary dryer is traditional and reliable drying equipment, the material will be lifted up and fallen down by the lifting plates inside of the cylinder while the cylinder is rotating, the moisture in the material is continuously evaporated when the material contacts with the hot wind inside of the cylinder, to achieve the purpose of drying materials. It is suitable for drying sludge, coal, sand, animal dung, fly ash, clay, coal slime, ore, steel slag, quartz sand, kaolin clay, bentonite, sawdust, desulfurization gypsum, compound fertilizer, etc.

 Working Principle：

  The working principle of a rotary dryer involves feeding the material to be dried into the rotating cylinder through the feeding device. The cylinder continuously rotates driven by the transmission device. Various types of lifting plates are installed inside the cylinder, which evenly spread the material, allowing it to fully contact with the hot air. This ensures efficient heat transfer and moisture evaporation, achieving the drying purpose. The dried material is then discharged from the outlet end, completing the entire drying process.

1.The operation parameters can be changed according to the different material properties,the material in the dryer cylinder can form stable material curtain, to make the heat exchange more fully;

2.New feeding and discharging device, put an end to the phenomenon of the plug in feeding,incontinuity, nonuniform and material return of traditional dryer, and reduce the load of dust removal system;

3.The adjustable stainless steel plates’ sealing are adopted at the connection of the feeding and discharging devices, it’s with good sealing property, which greatly reduces thethermal losses inside of the cylinder, so as to directly reduce the fuel consumption;

4.Counterflow drying method, it can obtain higher evaporation intensity; downstream drying method and indirect drying method are suitable for drying materials which are sensitive to temperature;

5.Fuel can be diesel oil, heavy oil, and natural gas, gas, coal, electricity and biomass particles for environmental protection;

6.All kinds of different types of lifting plates combination, to ensure the hot air is in full contact with the material, and meet the needs of drying different material.
