Heavy duty screw rotor

Carbon steel screw rotor for a rendering application. This is an example of our capability to manufacture spare parts for large process plants needing screw rotors for their heavy duty applications.

BEMA is able to measure and manufacture the screw rotor, which often sit in critical positions in process plants. BEMA has a full documented drawing system, and we are able to put a screw rotor into production 1-2 working days after receiving the order for a sparepart screw rotor.

In many cases we are able to supply screw rotors within 3-4 working weeks. In these cases you can use BEMA as a spare part supplier of vital screw rotor components.

What shall I do if I need BEMA to supply a spare part screw rotor?

1. Send BEMA a drawing from which we can make a production drawing
2. If do not have a drawing of your screw rotor, then take it out of  your system on a planned stop – make the measurements and send it to us
3. BEMA can travel to your site for measuring – but consider the distance and effort towards your own job here

You shall avoid not to have a critical screw rotor in plant without a reliable drawing. In case of an unexpected breakdown you are able to manufacture a new screw rotor as soon as the material is in our work shop.

If you keep screw rotors for your heavy duty application without documentation such an incident is very costly. First of all you will have to measure on a broken screw rotor. Secondly you need assistance from a technician to make the drawing and afterwards start the production. Such a behaviour are risky and increase the probability for  failures with even higher cost and an increased down time.

FAQ for Heavy‑Duty Screw Rotors

1. What materials are heavy‑duty screw rotors typically made from?

They are commonly manufactured from high‑strength steel or wear‑resistant alloys to withstand abrasion, impact loads, and continuous operation in demanding industrial environments.

2. How does a heavy‑duty screw rotor improve material handling efficiency?

The rotor’s optimized pitch, diameter, and flight geometry ensure stable throughput, reduced clogging, and consistent flow of bulk materials such as biomass, waste, aggregates, or industrial by‑products.

3. What factors determine the lifespan of a screw rotor?

Rotor lifespan depends on material hardness, surface treatment, operating speed, load conditions, and the abrasiveness of the transported material. Hardfacing and surface coatings can significantly extend service life.

4. Can heavy‑duty screw rotors be customized for specific applications?

Yes. Rotors can be tailored in length, pitch, flight thickness, shaft design, and surface protection to match capacity requirements, material characteristics, and installation constraints.
