screw conveyor for conveying powders and smaller materials

With its simple and compact design, the screw conveyor plays a key role in industrial systems where powders and small granular materials require hermetic conveying. It can also be customized according to customer requirements, such as setting up heating and cooling jackets, stirring blades and other structures to achieve composite process handling.

Screw conveyor can not only be used as a stand-alone system, but also commonly used in the production process of conveying, batching, mixing or discharge link, is an indispensable part of a variety of industrial processes.

Screw conveyor features:

1. Compact structure, occupies little space, suitable for the arrangement of the narrow operating environment.
2. Fully enclosed design effectively prevents dust leakage, enhancing the cleanliness and safety of the production environment.
3. It is suitable for horizontal, inclined or short-distance vertical conveying, and the installation mode is flexible and changeable.
4. Various forms of spiral body (such as solid spiral, belt spiral, vane spiral) can be selected according to the characteristics of the material, to enhance the conveying efficiency and stability.
5. The parts are easy to maintain and replace, reduce operation and maintenance costs, and extend service life.

The main advantages of screw conveyor:

1. It is adaptable, not only suitable for conveying dry powder, but also suitable for materials with certain humidity such as mortar or coal ash.
2. The closed conveying structure reduces material loss and avoids pollution.
3. It can be flexibly configured through multi-point inlet and outlet for material transfer at different stages of the production line, which is suitable for the access of automation control system.
4. Due to the sturdy structure and fewer moving parts, it has low failure rate and stable and reliable operation.

Working principle of screw conveyor:

The core component of the screw conveyor is the rotating screw blade, which rotates along the center axis driven by the drive motor. After entering from the inlet, the material is pushed by the thrust and friction of the rotating screw, and is slowly pushed along the inner wall of the shell. The material itself in the gravity and the role of friction with the groove wall to remain stationary, relative to the rotating spiral, it shows the “being pushed” state, from the discharge port discharge. This process is continuous and stable and is suitable for continuous operation.

Areas of application for screw conveyors:

Screw conveyors are suitable for a wide range of material handling requirements and are suitable for bulk materials with small granularity or a certain degree of fluidity. Its main application scenes include:

1. Building materials industry: for conveying cement, sand, lime powder and other dry bulk materials.
2. Metallurgical industry: to deal with industrial residual materials such as mineral powder and metal chips.
3. Chemical industry: conveying all kinds of chemical powders, granules, additives and so on.
4. Grain processing: suitable for conveying raw materials such as wheat, soybeans, corn, husk and so on.
5. Electric power and environmental protection: conveying boiler ash, desulfurization powder, dust collector collection and other solid particles.
6. Coal system: for conveying coal powder, gangue and other light solids.
