On-site Fluid Analysis in Minutes, not Days

It didn’t take a six-year federal study to show that miners want fluid analysis equipment on-site for speedy but comprehensive results as part of their equipments’ preventive maintenance programs. But that’s what a 2004 U.S. Department of Energy study concluded, and what an increasing number of respected players in the mining industry, including service provider Megatrol and equipment provider P&H Mining Equipment, are moving to implement.

“To stay maximally productive, mines need real-time information they can act on as part of their daily planning instead of a periodic checkup,” said Tom Barnes, product support manager, P&H Mining Equipment. “The reason: Equipment is bigger and more complex; mines are more remote; and sophisticated technical help is harder to get, especially in emerging markets.”

Understanding the Commercial Approval Process for Scales

The National Institute of Standards and Technology (NIST) Handbook 44 (HB44) is a set of specifications, tolerances and other technical requirements for weighing and measuring devices. State Weights and Measures Officials use this document to test and approve commercial weighing devices; hopper scales, truck scales, track scales, belt-conveyor scales, etc. Changes were recently implemented to NIST HB44 for the belt-conveyor scale section 2.21.

Flanders Electric Goes Head-to-Head with Electrical Engineers

Many mining companies face the problem of obtaining quality technical training for their employees. The challenge in mining today may be described as a knowledge gap, information transfer and technical training. Many companies are searching for ways to transfer technical knowledge from experienced employees to less-seasoned technicians.

Commercial-scale Test of New Technology to Recover Coal from Sludge Successful

A new technology for removing water from ultrafine coal slurry has been successfully tested at the commercial scale at an operating coal cleaning plant. The technology offers the possibility of reducing the coal slurry impoundment problem from the source. A peer-reviewed paper on this new technology was presented September 15 durring the 13th Australian Coal Preparation Society Conference in Cairns, Queensland.

Cleaning coal after it has been mined is done with water. The bulk of the coal mined is relatively coarse in size and, therefore, can be readily washed of impurities and subsequently dewatered. However, a portion of mined coal is smaller than approximately 30-40 microns and is difficult to dewater after cleaning, said Roe-Hoan Yoon, the Nicholas T. Camicia Professor of Mining and Mineral Engineering in Virginia Tech’s College of Engineering. As a result, finer coal is often discarded to slurry impoundments. There are hundreds of sludge impoundments in the United States, mostly in Appalachia, creating environmental and safety concerns, said Yoon.
