1 Mining for Solutions (September 2016)

Increasing pressure on many fronts is compelling mine operators to thoroughly examine every phase of their operations. Fluctuating demand that whipsaws mineral prices, government-imposed environmental regulations and rising operating costs related to maintenance downtime all pose serious challenges for the mining sector. Add pressure from customers and stakeholders for more sustainable operations as well as union demands for higher wages, and you have a scenario that requires mine operators to exercise every possible option to achieve more efficient operations.

2 When it Comes to Mining, Bigger is Best (June 2015)

One of the key challenges in the mining industry today is maintaining throughput in the face of ore grade quality that has declined by 40 percent in the last decade.

3 Nervy Enterprise and Edgy Engineering: A Cant-Miss Mix (June 2012)

Fairchild International, a U.S.-based manufacturer of underground mining equipment, has produced battery-powered DC scoops since the early 1980s. With 17 different models available, Fairchild offers a size to fit any coal mining operation, making it the leader in the industry.

4 Determining Diametral Pitch, Center Distance (October 2016)

I need help determining the diametral pitch needed to achieve the closest center-to-center distance for 2 spur gears. The 1st gear is a 34-tooth and the 2nd gear is a 28-tooth. The center-to-center distance between the gears needs to be as close to 2 1/8" as possible.

5 Recalibrated Equations for Determining Effect of Oil Filtration on Rolling Bearing Life (September 2015)

In 1991, Needelman and Zaretsky presented a set of empirically derived equations for bearing fatigue life (adjustment) factors (LFs) as a function of oil filter ratings.

6 Crowning Spur Teeth - Ask the Expert - December 2013 PTE (December 2013)

When designing spur teeth, is there a formula/guideline/design guide for determining the amount of crowning?

7 A Recipe for Quality Big Bearings (June 2010)

Many power transmission components require a certain level of customization for each individual project. The big bearing market is no exception. Construction, mining, steel, marine and wind applications aren’t exactly areas where customers buy bearings in bulk.

8 Designing for Static and Dynamic Loading of a Gear Reducer Housing with FEA (February 2010)

A recent trend has been a movement to more user-friendly products in the mechanical power transmission industry. A good example of such a product is a high-horsepower, right angle, shaft-mounted drive designed to minimize installation efforts. Commonly referred to as an alignment-free type, it allows the drive package mounting to be quicker, more cost effective and require less expertise during installation. This facilitates the use of the drive in applications such as underground mining, where there is little room to maneuver parts. The most common application for the alignment-free style drive is for powering bulk material handling belt conveyors.

9 Neighborhood Watch - Advancements in Condition Monitoring Equipment (June 2009)

Now more than ever, manufacturing companies are examining what steps need to be taken to ensure improvements to machine reliability by predicting system failures and minimizing downtime.

10 Analyzing the Cement Process (April 2016)

The manufacturing process begins in a limestone quarry. Mining methods such as ripping, dozing, drilling and blasting are commonly employed. Limestone provides the first essential component, calcium, for the anufacture of cement. Materials are transported to the crushing plant for further size reduction. Common methods of transport are trucks, loaders and belt conveyors.
