Product introduction

Richi Machinery industrial electric high quality roller drying machine are mainly composed of barrel device, front and rear supporting roller device, feeding and discharging device, etc. It is a type of industrial dryer employed to reduce or minimize the liquid moisture content of the material. It is suitable for drying wood sawdust, wood shavings, husk, grass, dregs and etc. It has advantages of low noise, fast delivery, reasonable design, high efficiency, low energy consumption and easy to operate. This roller dryer machine can be widely used in different fields, such as agricultural waste pellet line, wood pellet line, forestry waste pellet line,  straw pellet line, palm shell pellet line, waste organic matter pellet line, grass pellet line,etc.

Product advantages

  1. The roller drying machinehas a simple structure, a small footprint, and it is easy to construct and maintain.
  2. Simple system, safe and easy operation.
  3. The drying strength is large. Because the material is highly dispersed in the gas stream, the total surface area of the particles is extremely dry and effective.
  4. International standard with ISO, CE certificate.
  5. Large processing capacity and high thermal efficiency.
  6. Short drying time.
  7. Capable of installation anywhere in world.
  8. In house engineering for custom fit applications.

Working Principle

The material is transported by the scraper conveyor to the inside of the roller drying machine. and the front is equipped with a hot blast stove. The generated hot gas enters the roller drying machine through the fire separating device, and the material is dispersed through the low-speed rotation and bending plate. so that the high-temperature airflow passes through the material and make heat exchange, the roller dryer has a certain angle of inclination, and sufficient air volume to drive the material forward. Finally, the dried material is discharged from the discharge port.The temperature generated by the heat source enters the long refractory lining chamber to maintain a low temperature. Adding auxiliary air to the chamber to maintain a lower temperature level.

Application Of Roller Drying Machine

  1. Roller dryer is currently the most widely used equipment, and are capable of handling almost any bulk solid material regardless of its conveyance and handling characteristics.
  2. Suitable for feed and agriculture industries: straw, grass fish meal, leaves, food factory waste, corn sauce
  3. Suitable for bio-mass pellet industry: wood sawdust, wood chips, wood shavings, agricultural straw
  4. Suitable for organic fertilizer & compound fertilizer: organic & compound fertilizer granules, livestock manure waste, poultry manure, such like sheep manure, pig manure, chicken manure, caw manure etc. and compost, sludge.
  5. Suitable for drying powder and granular materials: phosphorus slag, crystals.
  6. Suitable for building materials drying, metallurgy and chemical industry, mining industries: respectively, sand, cement, ores, slag, coal, metal power, clay, kaolin.
