Tubular inclined ATEX screw conveyors

2 pcs. tubular inclined screw conveyors designed for food grade material to be placed in an ATEX zone. Tubular screw conveyors are often used in inclined application, because the material cannot fall back in the same way compared to a trough screw conveyor.

Important points to consider when screw conveyors shall be placed in ATEX-zones

1. As end client you must know exactly which ATEX-zone the screw conveyor shall be places in:
   1. Gas environment
   2. Dust environment
   3. Which zones are required inside the screw conveyor and outside round the screw conveyor
2. Based on the above specification, BEMA is available to design the screw conveyor to obey the ATEX requirements
3. If a higher ATEX demand is required, BEMA will handle the documentation send to the notified body

The first point is your ATEX-zone classification, which determines the level of ATEX requirements to designed into the screw conveyor.

In BEMA we mechanically design the screw conveyor for the defined ATEX-zones. We design to exactly obey the requirements without building unneccessarily means into the screw conveyor.

In the documentation of the screw conveyor, we add the ATEX specification into the declaration of conformity.

When you purchase a screw conveyor with ATEX approval in BEMA, we deliver you a complete documented product:

1. A machine drawing with referecence to the defined ATEX-zone/zones
2. The product with ATEX marking if necessary
3. Complete documentation with declaration of conformity

When you need a tubular screw conveyor with ATEX approval you shall be aware that it require relevant time for design and planning. Therefore be prepared with your ATEX-zone classifiaction before you contact BEMA.

FAQ for Tubular Inclined Screw Conveyors with ATEX Approval

1. What makes tubular screw conveyors suitable for inclined installations?

Tubular screw conveyors are ideal for inclined applications because the enclosed design prevents material from falling back during transport. This ensures stable flow, higher efficiency, and better performance compared to trough conveyors in similar angles.

2. What ATEX information must the end client provide before design can begin?

The end client must define the exact ATEX zone classification, including whether the environment involves gas or dust, and which ATEX zones apply inside the conveyor and around it. This classification determines the mechanical design requirements and documentation level.

3. How does BEMA ensure compliance with ATEX requirements?

BEMA designs the screw conveyor to match the specified ATEX zones precisely—no unnecessary components are added. The final product includes ATEX marking, a declaration of conformity, and complete documentation. If higher ATEX demands apply, BEMA manages communication with the notified body.

4. What should customers expect regarding project planning and delivery time?

ATEX‑approved tubular screw conveyors require thorough design and planning, so customers should be prepared with their ATEX classification before initiating the project. This ensures efficient engineering, correct documentation, and a smooth production process.
