The Importance of Safety in the Mining Industry

The rugged, high-stakes environment of the mining industry requires safety to be non-optional. Every piece of equipment, every process, and every decision must come together to ensure the livelihood of the workforce is preserved and operational excellence is achieved. From conveyor systems to hoists and grinding mills, these critical components play a large part in providing essential raw materials to the global economy. One crucial element that plays a vital role in all these sectors, however, is the braking systems of these heavy applications.

Benefits of Inching Drives

The mining industry relies heavily on efficient and reliable equipment to process large volumes of ore and mineral resources. One critical component in this ecosystem is the grinding mill, which plays a pivotal role in comminuting materials to prepare them for further processing. Grinding mills, particularly the large semi-autogenous (SAG) and ball mills, often operate under challenging conditions that demand precision, durability, and adaptability. A key technology enabling these mills to operate safely and efficiently is the hydraulic inching drive system.

The Modified Life Rating of Rolling Bearings: A Criterion for Gearbox Design and Reliability Optimization

Engineers typically learn that the bearing L10 life can be estimated using the so called “C/P method” — or the “basic rating life” of the bearing, a method rooted in the 1940s. Major developments have since led to the “modified rating life,” released in ISO 281:2007, which includes the aiso life modification factor. In this paper a succession of equations used for bearing life ratings are reviewed, and current bearing life rating practices are discussed in detail. It is shown that — despite the introduction more than 30 years ago of the adjustment factor of the basic rating life, and the standardization in 2007 of the aiso modification factor — use of these improved calculation methods are not practiced by all engineers. Indeed — many continue referring to the old model as a way of seeking compliance with existing, established practices.
