In the fast-paced world of steel production, where precision and time are critical, ultra-fast nozzle changers are transforming continuous casting....

While standard drills and countersinks handle most machining tasks, specialized hole tools take precision and efficiency to the next level....

Taps and dies are the unsung heroes of engineering. They cut the precise threads that make bolts, screws, and nuts interchangeable worldwide — keeping mining machines, cars, and factories running smoothly.

Drills may create holes, but for true precision and durability, countersinks and center drills take the stage. These tools refine, guide, and prepare holes so that fasteners fit perfectly and machining remains accurate.

If dies create the external threads on bolts and rods, then taps are their natural counterpart  cutting the internal threads...

Threads are everywhere  from the screws in your phone to the massive bolts holding mining equipment together. But how are these precise spiral grooves created? The answer lies in taps and dies, guided by DIN standards.

When it comes to machining steel, one of the most common tasks is creating precise holes. From simple fasteners to complex machine assemblies, holes must be accurate, smooth, and reliable. This is where drills and reamers — guided by DIN standards — play a central role.

Behind every powerful machine tool lies a simple question: how does the tool connect securely to the machine? This is where standards like DIN 10 and DIN 138 come in. They define the dimensions of shanks and sockets  the “handshake” between tools and machines.

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 mining and heavy industry, overhead cranes are essential for lifting and moving heavy loads. At the heart of these...

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 rotating machinery  from mining conveyors to crushers and ventilation fans  shafts must operate well below their critical speed to...

Cantilever beams are widely used in mining and heavy industrial equipment, particularly where support is only possible on one end....

In mining infrastructure and heavy machinery, beams are everywhere  from conveyor support frames to equipment platforms and structural walkways. One of the most common configurations is the simply supported beam, where the beam is supported at both ends but free to bend under load.

In the world of mining machinery and structural engineering, components rarely face a single type of stress. Instead, they often...

In mining and heavy industrial environments, components like beams, shafts, and structural arms often face intense loading that causes them...

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.

In the design of shafts, rods, and cylindrical components — especially in mining and heavy industrial machinery — rotational symmetry...

In mining and heavy industrial machinery, shafts are rarely subjected to just one type of load. Instead, they typically experience...

No matter how precise your calculations are, real-world uncertainties always exist in mechanical design. Material imperfections, dynamic loads, wear, and...

In the real world, components rarely experience a single, clean load. Instead, they’re often subjected to multiple forces acting in different directions. When it comes to shafts, axles, beams, and structural frames in mining and heavy industry, this results in combined bending moments, which must be carefully calculated for safe and efficient design.

Every mechanical structure must be able to resist two fundamental types of forces: tension (pulling) and compression (pushing). These are...

In mechanical and structural design especially for shafts, axles, and beams in mining machinery two critical stress types must be carefully evaluated: bending stress and shear stress.

In real-world engineering, components are rarely perfect cylinders or uniform beams. They include keyways, shoulders, holes, notches, and grooves — all of which introduce local stress intensification. This phenomenon is measured using the Stress Concentration Factor (SCF), known in engineering as K_t.

Accurate sizing of axles and shafts is crucial in the design of mechanical systems across mining, manufacturing, and heavy equipment sectors. Whether supporting load or transmitting torque, these components must be dimensioned to handle real-world conditions without failure, deflection, or premature fatigue.

Shafts are the backbone of mechanical power transmission in industrial machinery. In mining applications — such as crushers, conveyors, winches, and gearboxes — shafts are responsible for transferring large amounts of torque under severe conditions. That’s why understanding shaft strength calculation is essential for safe and efficient design.

Axles play a vital role in mechanical systems — especially in mining, transportation, and heavy lifting machinery. Whether they're supporting wheel hubs, guiding rollers, or acting as pivot points for rotating components, axles are constantly exposed to complex stress conditions, including bending, shear, and torsion.
