Introduction to Screw Conveyor Calculator

In the field of mechanical engineering, especially in the manufacturing, processing, and bulk material handling industries, the screw conveyor is one of the indispensable pieces of equipment. Screw conveyors transport materials continuously, stably, and cost-effectively. However, to design a highly efficient screw conveyor system, engineers must perform a series of complex calculations: from determining the type of material, rotation speed, capacity, diameter, deflection, drive power, to calculating weight and load-bearing capacity.

In the past, this process was often calculated manually using formulas or standard tables, which was prone to errors and time-consuming. That is why the screw conveyor calculator was developed as a powerful support tool for design engineers, helping to simplify the entire process, minimize risks, and increase accuracy.

The software is built with an intuitive interface, easy to use, and a clear workflow consisting of 8 basic steps:

Select material
Calculate speed
Calculate capacity
Calculate diameter
Calculate deflection
Calculate power
Calculate weight

In this article, we will explore each step in detail to see how the software optimizes screw conveyor design.

Select Material

The first and most important step in screw conveyor calculation is identifying the type of material to be transported.

Each material has its own characteristics in terms of particle size, moisture, abrasiveness, bulk density, and flowability. These factors directly affect the design of the screw conveyor, its diameter, rotational speed, and drive power.

The software provides a rich material database, including grains (corn, rice, bran, wheat flour) as well as heavy and abrasive materials (cement, sand, fly ash, coal). Users can simply select from the available list or enter their own data if the material is not included in the library.

A strong feature of the software is the ability to expand the material database, adapting to specific industries. For example, in the animal feed industry, users can add ingredients such as oil meal, premix, micro-minerals, etc. In the cement and construction materials industry, additional data such as ash, clinker, and gypsum can be entered.

Benefits:

Save time in material selection.
Reduce errors in determining parameters.
Standardize material data across the enterprise.

Calculate Speed

Once the material is selected, the software supports calculating the optimal screw speed.

The screw conveyor speed depends on several factors:

Flow characteristics of the material.
Screw diameter.
Required conveying capacity.
Working conditions (horizontal, inclined, vertical).

If the speed is too low, the required conveying capacity cannot be achieved. Conversely, if it is too high, the material may be thrown out, causing rapid wear of the flights and trough.

The software applies standard formulas according to CEMA/DIN and provides recommended speed ranges for comparison. It also issues warnings if the speed exceeds safe limits.

Example: When cement is selected, the software automatically calculates the ideal rotational speed to prevent sticking and minimize wear.

Calculate Capacity

Conveying capacity is a key parameter in screw conveyor design. It is determined based on:

Screw diameter.
Screw pitch.
Screw speed.
Fill factor.

The software calculates theoretical capacity and adjusts it to actual capacity according to the material characteristics.

Example: With the same screw diameter and speed, conveying corn kernels will achieve higher capacity than conveying wheat flour due to better flowability.

This function allows engineers to quickly check if the design meets production requirements. If not, parameters (speed, diameter, fill factor) can be adjusted to find the optimal solution.

Calculate Diameter

The screw diameter directly affects conveying capacity and required power.

The software calculates diameter based on:

Required capacity.
Material properties.
Screw length.

In addition to providing the optimal value, the software also suggests common market-standard diameters (D150, D200, D250, D300, …), enabling quick and practical selection.

Calculate Deflection

For long screw conveyors, shaft deflection must be carefully considered. Excessive shaft deflection reduces bearing life and can cause material jamming.

The software calculates shaft deflection accurately for each section and recommends the installation of intermediate bearings to minimize deformation.

This function is particularly useful for screw conveyors longer than 12 meters or operating under heavy loads.

Calculate Power

Motor power is a decisive factor in operating cost. If the power is too small, the screw will be overloaded and fail quickly. If oversized, investment and electricity costs will be wasted.

The software calculates required power based on:

Frictional resistance torque.
Material weight.
Inclination angle of the screw.
Service factor.

After calculation, the software provides a recommended power range and suggests suitable motor–gearbox options. This helps businesses optimize both initial investment and long-term operation.

Calculate Weight

The software also calculates the total weight of the screw conveyor, including:

Screw shaft.
Screw conveyor flights.
Trough casing.
Bearings and supports.

Knowing the exact weight allows engineers to estimate manufacturing costs and design appropriate structural frames and foundations.

Export Data

Once all steps are completed, users can export data in multiple formats:

Excel (detailed calculations).
PDF (technical reports).
CAD (preliminary design data).

This not only helps with storage but also facilitates information exchange between departments: design, production, business, and cost estimation.

Conclusion

The screw conveyor calculator is a powerful tool that helps mechanical engineers and businesses to:

Save design time.
Minimize calculation errors.
Optimize investment and operating costs.
Improve manufacturing and installation efficiency.

With its clear 8-step workflow and user-friendly interface, the software is useful not only for experienced professionals but also for students and young engineers in their learning and research.

It can be said that the development of this software marks an important step in the digitalization of mechanical design, making industry more modern and efficient.
