Horizontal screw conveyors for industrial use

Horizontal screw conveyors manufactured for industrial use. The screw conveyor type is through screw conveyors. A screw conveyor is considered as horizontal in case the inclination is less than 15°. In this project BEMA has manufactured 4 pcs. horizontal screw conveyors.

What features are applied into an industrial application with screw conveyors?

1. The screw conveyor trough is manufactured in 5 mm. thickness
2. The drive station is manufactured with a torque arm enable to take up the full load in case the screw rotor is blocked
3. Look on the pictures to see the torque arm
4. Bearings in drive and following end are spherical roller bearings
5. Paint is performed to class C5

Horizontal through screw conveyors are used in many different applications for transporting bulk material in rough industrial environment.

Examples of materials transported in horizontal through screw conveyors

1. Ash or slags
2. Stone material from mineral process industry
3. Grain material
4. Waste products from industrial processes

See another expample of a screw conveyor for industrial use BEMA has experience in assisting customers with the optimal design of their horizontal screw conveyors. During the design phase, the key points to take care of are:

1. Determine the flow rate for the screw conveyor
2. Material selection
3. Size of the screw conveyor
4. Determine the size of the gear box
5. Clarify if special actions have to be taken for the inlet and outlet

What filling degree should be designed for a horizontal screw conveyor?

• A horizontal screw conveyor should in general have a filling degree of 30%
• In case of abrasive material it shall be less – down to 10%
• For light flowing material the filling degree can be increased to 40-45% as a maximum

BEMA has its own design department. Our engineers and technicians have year long experience in designing screw conveyors to last for 10 years or more. In one of the pictures the packing of the screw conveyors are shown before shipping. BEMA is able to pack into wooden boxes and frames ready for:

1. Truck transport
2. Container transport
3. Air transport

All woods used are ISPM-15 approved, and we are certified to mark the wood according to requirements from authorities.

FAQ: Horizontal Screw Conveyors for Industrial Use

1. What are horizontal screw conveyors used for?

Horizontal screw conveyors are designed for transporting bulk materials in demanding industrial environments. They are considered horizontal when the inclination is below 15°, making them ideal for stable, controlled material handling in a wide range of applications.

2. What key design features improve durability and performance?

The trough is manufactured in 5 mm steel for strength, and the drive station includes a torque arm capable of absorbing full load if the screw rotor blocks. Spherical roller bearings are used at both ends, and the conveyors are painted to corrosion‑resistant class C5.

3. Which materials can be transported in horizontal screw conveyors?

These conveyors handle a wide variety of industrial materials, including ash, slags, stone from mineral processing, grain, and general industrial waste products. Their robust construction makes them suitable for rough operating conditions.

4. How does BEMA support customers during the design phase?

BEMA assists with determining flow rate, selecting materials, sizing the conveyor and gearbox, and clarifying inlet and outlet requirements. Their engineering team designs conveyors to achieve long service life—often 10 years or more—and provides packing solutions for truck, container, or air transport.
