Several complex systems play a vital role in various industries, like screw conveyors. This article offers some deep insight into these systems, their components, and sizes.
What Are Screw Conveyors?
A screw conveyor is a mechanical device consisting of a rotating tube (screw) that moves materials from one location to another. The screw is usually enclosed in a housing (tube or trough), and either has a horizontal or inclined orientation. This system is often used in agricultural, industrial, and mining applications.
What Are the Basic Screw Conveyor Components?
Screw conveyors can be manufactured in various sizes and with different features. But most screw conveyors will share some essential components.
- The screw: The screw is the central moving part of the system and is what moves the material from one location to another. It is usually made from stainless steel or carbon steel material.
- The housing: The housing encloses the screw to keep materials within the system. It also provides support for the bearings and motor (if applicable).
- The bearings: Bearings are located at either end of the screw conveyor. They support the rotation of the screw and keep it in place.
- The motor: A motor is not always required, but it is a common component in screw conveyors used for industrial applications.
What Are the Common Screw Conveyor Sizes?
Screw conveyors are manufactured in a variety of sizes. The size will be based on the intended application and the amount of material that needs to be moved.
The most common sizes are:
- 4" diameter – This size is typically used for agricultural applications.
- 6" diameter – This size is a common choice for industrial applications.
- 9" diameter – This size is often used in mining applications.
What Are the Different Types of Screw Conveyors?
There are three main types of screw conveyors:
Shafted screw conveyors are the most common type. They consist of a shaft that runs the length of the conveyor with a helical screw blade attached to it. The blades rotate when the shaft turns and move material along the conveyor.
Shaftless screw conveyors are similar to shafted screw conveyors but do not have a shaft. Instead, the screw blades are mounted directly to the housing. This type of screw conveyor is often used in applications where materials are sticky or difficult to move.
Vertical screw conveyors are also similar to shafted screw conveyors but are oriented in a vertical position. They are often used in tight spaces or where materials need to be moved up or down.
Understanding the essential components and sizes of screw conveyors is crucial if you are in an industry that uses them, and it’s essential to know the different types to choose the right one for your application.
