Powder screw conveyors for fishmeal

Powder transport of fishmeal is in general easy, but in parts of the process the fishmeal can be a little sticky and require attention.

What do BEMA suggest when we design powder screw conveyors for fishmeal?

1. Ensure that the filling degress i lower than 30%
2. Do not use intermediate bearings for the screw conveyors
3. Manufacture all in 1.4301/AISI-304 stainless steel

If these guidelines are followed the screw conveyors will last for many years and require very little maintenance. See another project delivered for the food industry here Screw conveyors for powder and granules covers a very broad range of different types of screw conveyors and design. Working with powders and granules require the technician to be cautious.

Which Type of information is necessary working with powder for screw conveyor transport?

1. The density
2. Clarify if the material can fluidize
3. Ensure that the angle with horizontal is at least 15° below the slip angle of the material
4. Clarify if the material is sticky and require a special design of the screw flights

BEMA has our own engineers and technicians. These can assist during the design process to get the right design of the screw conveyors and other related transport equipment.

FAQ: Powder Screw Conveyors for Fishmeal

1. What are powder screw conveyors for fishmeal used for?

They are designed to transport fishmeal efficiently throughout the production process. The conveyors handle both easy‑flowing powder and slightly sticky fishmeal, ensuring stable and reliable material movement in fishmeal plants.

2. What does BEMA deliver as part of a complete project?

BEMA designs all screw conveyors and bucket elevators based on factory layout drawings, selects the correct steel materials, manufactures the equipment, performs assembly and testing, ships the full system, and provides complete documentation for future maintenance.

3. What design guidelines does BEMA recommend for fishmeal transport?

BEMA advises keeping the filling degree below 30%, avoiding intermediate bearings, and manufacturing all components in 1.4301/AISI‑304 stainless steel. Following these guidelines ensures long service life and minimal maintenance.

4. What information is needed when designing screw conveyors for powders?

Key factors include material density, whether the powder can fluidize, the slip angle to determine conveyor inclination, and whether the material is sticky and requires special screw flight design. This ensures optimal performance and reliable operation.
