Function Information of Rotary Dryer

  Rotary dryer is widely used in construction materials, metallurgical industry, chemical engineering industry and cement industry to dry limestone, coal dust, ore slag, clay and other materials. The machine is composed of rotary body, material lifting plate, transmission device, supporting device, obturating ring and other parts. The machine has reasonable structure, perfect workmanship, high productivity, low energy consumption and so on. We can guarantee the quality of our machines and also make free installation and debugging. We believe quality is the soul of an enterprise and we also value our credit and reputation. Welcome to our factory to have a visit and make a comparation with other companies in respect of quality, price and service.
   Ⅰ.Usage and purpose.
  The rotary dryer is called dryer for short. It is a type of drying machine used to handle materials in large quantities. Due to its reliable operation, excellent adaptability and large handling capacity, it is widely used in metallurgical industry, construction materials, food industry, light industry, chemical engineering industry, coal industry, mining industry and pharmaceuticals industry. The machine is applicable to granular materials, sticky and paste materials or watery materials. The advantages are high productivity, wide application scope, small flow resistance force, easy operation and so on. It is commonly used to dry sand, powdered ore, coal slurry, fowl manure, cow manure and so on.
  Ⅱ. Structure and principle.
  1. Structural diagram.

   The rotary drum dryer is composed of 1.drum; 2.front roller; 3.back roller; 4.gear; 5.block roller; 6.drag roller; 7.pinion; 8.discharging port; 9.material dispersion sling; 10.reducer; 11.motor; 12.hot air duct; 13.inputting chute; 14.furnace body and other parts. Additionally, we can also make special customization of gas producer, combustion chamber, auxiliary lifter, belt conveyor, constant feeder, dust collector cyclone, draught fan, etc.

  2. Working principle of rotary drum dryer.
   When the material is delivered to the hopper by the belt conveyor or bucket lifter, it will be fed into the charging end via the charging machine of the hopper. And also the slope of the charging pipeline should be bigger than the natural angle of the material, which will make sure the material moving smoothly into the dryer. The rotary drum of the dryer is slightly inclined, and the material is fed from the high end while the heat carrier is from the low end; or both of the material and the heat carrier are put into the drum together at the high end and move to the low end with the rotation of the drum. When the wet material moves forward, it will be dried by the heat carrier and sent out by belt conveyor or spiral conveyor. There is an interior dispersion sling to throw the material up and down in order to raise the drying rate and make the material move forward. The dust collector cyclone should be used to collect the material in the hot air after the heat carrier has gone through the dryer. If there is need to reduce the dust discharging, the pulse bag filter or hydro-scrubber can be adopted.
