Horizontal tube screw conveyors for gypsum

Horizontal tube screw conveyors for gypsum transport manufactured for gypsum plaster factory. All the screw conveyors are manufactured as tube conveyors. Gypsum is easy to transport in a screw conveyor and it is not necessary to overview the screw rotor on regular basis. The horizontal tube screw conveyors are designed and manufactured for industrial use.

Key points for the solution

• Designed for a silent indstrial environment. All screw rotors are manufactured with a self carried inner tube.
• Designed to be as closed as possible – this is the reason for using the tube conveyor type
• Designed with ribbon screw flights to avoid clocking of the screw rotor in case of sticky material. Gypsum can be sticky with a high water content
• Painted performed to class C5

BEMA has manufacted several solutions for the gypsum industry. We have a key process machine for a gypsum plaster factory – our ACTA cruser. The ACTA crusher is used in many gypsum plaster factories. Learn more about the ACTA crusher here See an example of an ACTA crusher with a screw conveyor here In BEMA we design industrial applications for horizontal tube screw conveyors for gypsum transport to have a lifetime of at least 10 year.

Key points in the design to ensure a long lifte time for horizontal tube screw conveyors are:

1. Thickness of the screw conveyor housing shall be at least 4 mm
2. Thickness of the screw flights shall be at least 5 mm
3. Pack boxes shall be with manufactured with braided packings
4. Bearings shall be placed in a distance from the screw conveyor housing

With our own design department we can combine our ACTA crusher with screw conveyors for further transport of the gypsum. In this project we solved the a transport assignment without a crusher. All orders in BEMA are customer specfic depending on the actual requirement.

FAQ – Horizontal Tube Screw Conveyors for Gypsum

1. Purpose of horizontal tube screw conveyors for gypsum

Horizontal tube screw conveyors are designed for efficient and reliable transport of gypsum in industrial environments. Gypsum is easy to convey in a screw system, and the process requires minimal supervision of the screw rotor, making it ideal for continuous operation in gypsum plaster production.

2. Why tube screw conveyors are chosen for gypsum

Tube conveyors are selected because they are designed to be as closed as possible, reducing dust, spillage and environmental impact. This enclosed construction also supports a quieter working environment and protects sticky or moisture‑rich gypsum from external conditions.

3. How the design prevents clogging and ensures stable flow

The conveyors are equipped with ribbon screw flights, which significantly reduce the risk of clogging when handling sticky gypsum with high water content. The ribbon design improves material flow and reduces mechanical stress on the equipment.

4. Materials and construction features that ensure long lifetime

To achieve a minimum lifetime of 10 years, the housing is built with at least 4 mm steel thickness, and the screw flights with at least 5 mm. Pack boxes use braided packings, and bearings are placed at a distance from the housing to avoid wear from moisture and material contact.

5. How BEMA customizes solutions for gypsum handling

BEMA designs customer‑specific systems and can integrate tube screw conveyors with other equipment such as the ACTA crusher for complete gypsum‑handling lines. Each solution is engineered to match capacity requirements and process layout precisely.
