Production of screw segments Ø 250 mm (3 mm)

Manufacturing of Auger Segments Ø 250 mm with 3 mm Thickness

Designing new conveyor lines or performing a major overhaul of existing mechanisms at agricultural enterprises requires a rational selection of working organs. The main engineering task in such cases is to ensure the necessary throughput for grain handling while avoiding excessive loading of the central shaft and drive unit. A balanced solution for these conditions is a working organ with a diameter of 250 mm and a metal thickness of 3 mm — this size combines lightweight construction with sufficient rigidity for transporting agricultural crops. For engineers and repair crews who install equipment independently, the professional manufacturing of auger segments as individual parts guarantees exact geometric compliance with technical calculations, significantly simplifies and speeds up the installation process on the central shaft, and lays the foundation for the subsequent stable operation of the assembled unit.

Technological Advantages of Auger Segments Manufactured at the Zavod Moroza

During the creation or major repair of a conveyor line, the physical state of each individual flight plays a decisive role. Manufacturing parts using the method of step-by-step spatial bending allows for the full preservation of the initial metal thickness in all areas. The 3 mm steel used remains uniform at the base as well as at the outer edge that interacts with the raw material; such an even distribution of metal prevents rapid wear of the working organ in zones of highest friction.

An important consequence of this technology is the absence of hidden internal stress in the material, as the part is formed without aggressive mechanical stretching, allowing the steel to maintain its natural structural integrity. The finished segment does not spring back or change shape under load, which guarantees stable adherence to the specified spiral pitch along the entire length of the line.

For specialists directly performing the assembly of the unit, these properties translate into speed and quality of installation. Elements with correct spatial geometry fit tightly to the central shaft joint-to-joint, without the formation of gaps, allowing the welder to apply a reliable and neat seam without wasting time on forced fitting or tightening of the blades. A strong welded joint without local overheating of the supporting pipe avoids axis distortion and ensures smooth and stable operation of the assembled mechanism.

Auger Segment Manufacturing Technology

The basis for the reliable manufacturing of auger segments at the Zavod Moroza is a two-stage production process, which we provide as a specialized engineering service. The work begins with precise metal cutting — flat ring blanks are cut on CNC (Computer Numerical Control) machines. This stage guarantees absolute precision of the internal and external diameters of the future part; thanks to this approach, dimensional errors are completely eliminated, which is critically important for the subsequent correct seating of the flight onto the central shaft and maintaining a uniform operating clearance in the conveyor housing.

The second stage is matrix spatial bending of the prepared rings on a specialized hydraulic press. During this operation, the metal is carefully formed into a flight with a clearly specified spiral pitch. The main advantage of such forming is that the steel is not subjected to mechanical stretching. The profile does not thin out at the outer edge, stably maintaining the original 3 mm thickness across its entire plane. As a result, the customer receives a geometrically correct part that perfectly matches the original drawings and is ready for installation without additional locksmithing work.

The Zavod Moroza supplies components to enterprises and simultaneously utilizes these parts in the assembly of its own conveyor equipment and agricultural machinery. Years of practical experience, constant servicing of industrial and agricultural enterprises, and regular feedback from operators give us a deep understanding of all the nuances of screw mechanism operation. Our design department also helps solve complex tasks in the form of precise engineering performance calculations, designing non-standard units, and developing modernization plans for existing lines.

Although the 250x3 mm size is a high-demand base, we flexibly adapt production to specific technical conditions. In addition to standard parameters, we manufacture parts with left or right spiral directions, change the flight pitch for specific loading or unloading zones, and form working organs from other metal grades, in any required diameters (from 100, 150, 200, 300, 350, 400 mm and more) and rolled thicknesses (3, 4, 6, 8, 10, 12, up to 16 mm).

Our specialists clearly understand the key needs of engineers and repair crews — the part must strictly correspond to the calculations and be on-site on time. Send us your drawings or contact the technical department to coordinate parameters, and we will quickly ship finished parts from stock or launch the necessary batch into production followed by fast delivery directly to your enterprise.
