When it comes to shaping and machining steel, precision is everything. A drill bit labeled “5mm” must always measure 5mm, no matter who manufactured it. This is where DIN standards (Deutsches Institut für Normung) come into play. Established in Germany, DIN ensures that tools and components are consistent, reliable, and interchangeable.
Many rotating shafts in mining and industrial equipment run on journal bearings also known as plain bearings. Unlike ball bearings, which use rolling elements, journal bearings rely on sliding contact between the shaft and bearing surface.They are strong, simple, and cost-effective, but they face two constant challenges: friction and wear.
In modern steelmaking, precision and sustainability go hand in hand. At Steltech, we focus on engineering solutions that boost efficiency, cut costs, and deliver higher-quality steel. One of the most powerful innovations in this space is the Carbon Multi-Point Injection System for Electric Arc Furnaces (EAFs).
Intermediate shafts are a vital part of gearboxes used in mining machinery, such as conveyor drives, crushers, and hoists. They transfer torque between input and output shafts, often under high loads and variable conditions. Designing these shafts requires careful calculation to ensure they resist bending, torsion, and fatigue stresses.
In mining machinery, shafts transmit enormous amounts of torque from conveyor drives to crusher rotors. But when torque varies dynamically, shafts are exposed to torsional vibrations, which can be just as dangerous as bending oscillations. If these vibrations align with the shaft’s critical angular speed, catastrophic failures may occur.
In structural and mechanical design especially in mining equipment the direction and application point of a force significantly affect how the system behaves. Many real-world loads aren’t perfectly vertical or horizontal, so engineers must break these forces into components to analyze how they generate bending moments, shear forces, or torsion.
This blog explores how decomposing forces helps engineers accurately calculate bending moments in shafts, beams, and load-bearing structures found in mining applications.
