A screw conveyor comes in many forms. But they share one common property – that is for the handling of bulk materials. Different conveyors are used to shift materials using a screw shaft. However, there are common issues. This can include dust leakage, wear, and incorrect applications.

Screw conveyors have to match the materials they carry. Otherwise, they can be damaged by excess heat and abrasive materials.

This is where tubular screw conveyors come into play. In this article, we’ll explain how they work and the benefits of this system.

How Does a Tubular Screw Conveyor Work?

To understand how a tubular screw conveyor works, we can look at the basic systems of screw conveyance and compare. Here, we’ll look at the example of a standard horizontal screw conveyor.

Horizontal Screw Conveyor

  1. The conveyor is powered by a motor attached to the screw shaft.
  2. On the other side of the conveyor is the inlet where materials enter.
  3. As the motor turns the shaft, materials are churned through the system till they reach the outlet.

Such conveyors can transport food, chemicals and pharmaceutical materials in bulk. But these machines are static in a sense. There is no external motion to push materials through without the motor. As a result, they can be slow to carry sluggish or viscous materials. Thus, the load has to be lowered to improve efficiency, which means fewer materials can be processed. In addition, attempting a regular load can jam the screw shaft and cause damage to the machinery.

Tubular Screw Conveyor

With a tubular screw shaft, materials are enclosed in a tube shape. This creates a dust-free environment and decreases material build-up. In addition, the diameter of the tube can match the specifications of the materials it carries to improve flow. It can also be set at an incline to use gravity as a force to funnel materials, among other crucial advantages.

Advantages of a Tubular Screw Conveyor

  • Tubular screw conveyors can be custom designed for different applications and specifications.
  • It is constructed using heavy-duty materials such as stainless steel to carry heavier loads.
  • It can adapt to specialized flights, bearings, mountings, inlets and outlets.
