Many people lack a clear reference standard when selecting a screw conveyor. This article provides essential guidelines for those looking to purchase a screw conveyor.
Key Factors to Consider When Selecting a Screw Conveyor
-
Conveying Capacity
The conveying capacity of a screw conveyor refers to the amount of material transported per unit time. When handling bulk materials, capacity is measured in mass or volume per hour, while for finished items, it is measured in units per hour. If used alongside vibrating screen equipment such as linear vibrating screens, rotary vibrating screens, or ultrasonic vibrating screens, the feed rate should be carefully calculated to match the screen’s processing capacity. It’s crucial to determine whether the conveyor will be integrated with other production equipment before designing and manufacturing it. -
Conveying Speed
Increasing the conveying speed can enhance efficiency. However, factors like vibration, noise, starting, and braking must be considered, especially in high-speed belt conveyors. For conveyors using chains as traction members, excessive speed should be avoided to prevent increased power loads. In cases where the conveyor also plays a role in process control, the conveying speed should align with production requirements.

Component Size
The size of conveyor components—such as belt width, slat width, hopper volume, pipe diameter, and container dimensions—directly affects the conveyor’s capacity. Choosing the right dimensions ensures optimal performance and efficiency. -
Conveying Length and Inclination
The length and inclination of the conveyor line impact total resistance and required power. Some conveyors operate horizontally, while others have a specific inclination angle. When selecting a screw conveyor, it’s essential to specify these operational conditions to ensure proper design and functionality. -
Motor Selection
Screw conveyors can be equipped with either adjustable-speed motors or standard motors to regulate conveying speed and control material flow per hour. The choice of motor should align with the desired level of control and automation. -
Hopper Requirements
Determine whether a hopper is needed at the feed inlet and specify its size. A properly sized hopper can improve feeding efficiency and overall system performance.
By considering these factors, buyers can make informed decisions when selecting a screw conveyor that meets their specific industrial needs.
