The internal screw structure of the screw barrel is designed for efficient material conveying. This design is a key factor in ensuring that the equipment can reliably convey and handle materials in a variety of industrial applications.
screw barrel typically consist of two main components: the outer barrel and the inner screw. The inner screw is the core component of the equipment and is responsible for pushing and conveying the material. It is usually helical, in the shape of a screw thread, extending along the entire length of the drum. The geometry of the helix allows the inner screw to create helical channels as it rotates so that material can be pushed, lifted and conveyed along the channels.
The inner screw is available with different screw gaps and screw diameters, which can be adjusted depending on the type of material being handled and the application. Larger screw gaps can accommodate materials with larger particles, while smaller screw gaps are suitable for powders or materials with smaller particles. The diameter of the screw can also be adjusted as needed to provide the desired conveying speed and capacity.
The inner screw is usually made of wear-resistant materials to ensure that it is not susceptible to wear and tear over extended periods of time. This design can be adapted to handle a wide range of different materials, including granules, powders, liquids and viscous materials.
The inlet and outlet ports are also included in the design of the screw barrel. The material is introduced through the inlet and then conveyed by the inner screw down the spiral channel to the outlet. This process is continuous, allowing for efficient material transfer.
The rotational speed and power of the inner screw can be adjusted according to the specific application requirements to ensure that the material can be conveyed at the desired speed and to maintain the efficient performance of the equipment.
