A screw conveyor is a shaft with helical flights that rotates inside a tube or conveyor body.

When the shaft turns, the flights move the material and push it forward. In simple terms:

The screw rotates → The flights move the material → The material reaches the required place.

A screw conveyor can be used in several stages, including:

• Moving raw materials into the production line.
• Moving ground material from the grinder to the batching stage.
• Moving materials between some stages of the line.
• Feeding the pellet mill bin.

Where the screw conveyor is used varies depending on the production line design.

Because materials need to move continuously from one stage to another. Instead of moving material by hand, the screw conveyor moves it continuously and in an orderly way. This helps with:

• Keeping the line running.
• Reducing manual effort.
• Organizing the flow of materials.
• Reducing losses during transport.

When the motor starts, the helical shaft begins to rotate. The flights on the shaft move the material forward until it reaches the conveyor's discharge opening.

The material keeps moving this way as long as the conveyor is running and is being fed with material.

Yes, a screw conveyor can be used to move materials upward at a suitable incline, but the steeper the incline, the lower the conveyor's efficiency.

The way material is moved is therefore chosen according to the height of the location, the distance required, and the production line design. For very large heights, a bucket elevator may be more suitable than a screw conveyor, depending on the line design.

No.

The screw conveyor varies according to the production line's needs. Things that are determined include:

• The conveyor diameter.
• The conveyor length.
• The degree of incline.
• The type of material.
• The quantity of material to be moved.

A screw conveyor is therefore not chosen by diameter alone, but according to the whole line.

A screw conveyor's ability to move material is affected by several factors, the most important being:

Conveyor diameter + length + rotation speed + type of material + degree of incline.

There is therefore no single size that suits all feed lines.

If the screw conveyor is smaller than the line needs, it may not be able to move the required quantity of material at the right speed.

This can lead to material not reaching the next stage in the required quantity. The screw conveyor must therefore be chosen according to the line's output.

A screw conveyor works more efficiently when the incline suits the line design. The steeper the incline, the harder it becomes to move the material, and the amount of material the conveyor can move may drop.

The conveyor's length and incline must therefore be determined before manufacturing.

It moves raw materials or feed from one place to another inside the production line.

Yes, it can be used to move ground material from the grinder to the batching stage, depending on the line design.

Yes, it can be used to feed the pellet mill bin with material continuously.

A screw conveyor is suited to horizontal or inclined conveying, and the suitable way of conveying should be chosen according to the height of the location and the line design.

It is chosen according to the line's output, the type of material, the conveyor's length, and the degree of incline.

Yes, the conveyor's length, the type of material, and the way it is used affect the power required from the motor.
