Heating screw conveyors

Heating screw conveyors

High temperature screw conveyors can perform the following functions:

Conveying Materials: Conveying materials exposed to high temperatures from one location to another. This includes materials such as cement, steel, chemicals and food.

Mixing materials: Used to mix and mix materials during transportation. This is useful for applications where multiple materials need to be combined prior to processing or storage.

Cooling material: It can be designed with cooling jacket or other cooling system to reduce the temperature of the conveying material. This is useful for applications where the material needs to be cooled before processing or storage.

Heating materials: a heating system can be designed to increase the temperature of the conveying materials. This is useful for applications where materials need to be heated prior to processing or storage.

Mixing and reaction of chemicals: used to transport chemicals that need to be mixed or reacted at high temperature. This is useful in chemical processing applications.

A high-temperature screw conveyor is used to convey materials exposed to high temperatures (usually above 200°C (392°F)), and its structure generally consists of the following parts:

Screw: The screw or auger is the main component of the conveyor. It is a helical blade that rotates inside a trough or tube to move material forward. Screws are usually made of high temperature resistant materials such as stainless steel or Inconel.

Chute: The trough is the structure that houses the screw and guides the material being conveyed. Tanks are usually made of high temperature resistant materials such as stainless steel or carbon steel.

Bearings: Bearings support the rotating screw so that it rotates smoothly. Bearings must be able to withstand the high temperatures of the materials being transported. Special high temperature bearings may be required.

Drive system: The drive system provides power to the rotating screw. It usually consists of an electric motor and a gearbox.

Sealing system: The sealing system prevents material leakage and keeps the working environment clean. Special high temperature seals may be required to prevent premature failure.

Cooling System: A cooling system may be required to prevent overheating of material or conveyor components. For example, hollow screw designs with cooling jackets are available for heat dissipation.

Safety system: A safety system should be established to prevent accidents or injuries due to the high temperature of the transported materials. This may include temperature sensors, sirens and automatic shutdown systems.
