Product Description

Rotary dryers are an industrial drying system prized for their high capacity, heavy-duty build, and reliability, which has made them an ideal choice for efficiently drying bulk solids of all types, despite variable in the raw feedstock. The article services to give a basic overview of rotary dryers and the industrial drying process, as well as answer some of the common questions asked about the drying system.

1.The Components of Rotary Dryers

1.1 Shell: The shell of the rotary dryer can be made from a variety of materials, including carbon steel, stainless steel and a variety of alloys.

1.2 Raw material feed: The raw material feed area, also called the feed chute, is where feedstock is fed into the system, typically by a feed a crew or chute.

1.3 Drive assembly: The drive assembly is the mechanism that causes the drum to rotate. Several options are available here, but the gear and pinion are the best choices.

1.4 Riding ring: Riding ring add structural support for the drum, and serve as a place to burden the pressure of the whole shell.

1.5 Thrust rollers: Thrust rollers push on the riding ring to stop the drum from drifting, or moving horizontally.

1.6 Flights: Available in several designs, material lifter, or flights, help to maximize the efficiency of heat transfer between the material and the drying air.

1.7 Product discharge: The product discharge area is where the product exits the dryer. Here, the product can move on to the next step in the process flow.

1.8 Knocking systems: Knocking systems help to prevent build-up within the dryer, by knocking off material as the drum rotates.

2.How Rotary Dryers Work

Rotary dryers are comprised of a rotating drum, into which the material is fed, in combination with the drying air. Flights, or lifters, pick up the material from the bed, carrying it over, and dropping it through the air stream as the drum rotates to maximize heat transfer between the material and drying air. The tumbling action given by a drum offers the added benefit of polishing the pellets, further rounding them as they dry.

3.Characteristics of rotary dryers

3.1 The shell of the rotary dryer uses assembled structure, it is easy to transport

3.2 Add granulation area, improves the granulation effect, increase the surface finish and strength of particle

3.3 The banking plank adopts modular structure, for the materials, bestrew the entire interface of the shell, so that heat exchange is thorough.

3.4 Set with a thermometer, vibration device, sealing devices, improves production efficiency, the structure is simple and maintenance is easy.
