Controlling Material Flow in Pits: Complete Plant equipped with Belt Scales

By L. Henke Belt conveyors are the standard for the transport of materials in pits and quarries. To control the material flow and the inventory of these materials, belt scales turn out to be the optimum choice, as they are easy to retrofit in existing plants. Continue reading Controlling Material Flow in Pits: Complete Plant equipped with Belt Scales

Self-Contained Condition Monitoring of Conveying Systems: Sensing Idlers help Plant Operators to keep their Belt Conveyors running

By H. Eckhardt, A. Wahls Idlers can be a weak spot in conveyor belt systems with lengths of several km. If they heat up, this can lead to a breakdown of the system, or even an inflammation of the belt. Therefore, information about the state of the idlers is of paramount interest. Continue reading Self-Contained Condition Monitoring of Conveying Systems: Sensing Idlers help Plant Operators to keep their Belt Conveyors running

Transforming Waste to Value! Municipal Recovery Facility safes Resources and Dump Space

By P. Raschio , S. HuntMunicipal waste contains a high percentage of materials, whose recycling can be profitable due to the substitute of (limited) resources as well as saving valuable dump space. In Perth, Western Australia, a highly advanced facility has just gone operative. Continue reading Transforming Waste to Value! Municipal Recovery Facility safes Resources and Dump Space

If Crusher-Availability counts: Failure to adequately maintain Crushers comes at a high Price

By E. JonesFunctioning crushers are of paramount interest for the production of many mines and quarries. The following article runs through maintenance tasks a user might take to prolong the service life of his crusher. Continue reading If Crusher-Availability counts: Failure to adequately maintain Crushers comes at a high Price

Titans in Texas: Coal for South Texas’ and Northern Mexico’s Power Stations

By M. AdamsM. LinnemannCoal deposits with thin seams and many interlayers can be mined economically by surface miners, which can cut the exact depth of the coal layer and deliver the coal ready for belt conveyance without further crushing. Continue reading Titans in Texas: Coal for South Texas’ and Northern Mexico’s Power Stations

How to achieve a clean Conveyor Path: Innovative Belt Cleaning Technology eliminates Carryback at Cement Plant

By J. Cairns After installing an innovative primary cleaner designed for punishing applications a Detroit cement producer could stop excessive carryback and equipment fouling. With a significant reduction in carryback, spillage, and labor for cleanup, the plant was able to improve work­place safety, lower the cost of operation and see a quick return on investment. Continue reading How to achieve a clean Conveyor Path: Innovative Belt Cleaning Technology eliminates Carryback at Cement Plant

Stresses in Silos Part 2: Stresses in Hoppers – Disturbances to the Stress Distribution

By D. Schulze The first part of the paper on stresses in silos [10] focused on the bulk solid properties with respect to stresses, and the stresses in the vertical part of a silo. The present second part explains the stresses acting in hoppers for filling and emptying conditions. In die ideal case stress distributions are symmetric and uniform. However, in a real silo stresses may change locally, and stresses can be non-uniform along the circumference of a silo. Since this can result in consequences on the stability of a silo, the major sources of disturbances to the stress distribution are outlined. If appropriate, it will be referred to the bulk solid properties explained in part 1 [10]. Continue reading Stresses in Silos Part 2: Stresses in Hoppers – Disturbances to the Stress Distribution

Online Moisture Measurement: Non-Contact NIR Moisture Sensors in Powder and Bulk Solids

By A. Fordham Moisture content varies widely in raw materials, and at different points in production processes, so non-contact moisture measurement is essential for final product quality. Near-Infrared technology offers a perfect solution to this Task. Continue reading Online Moisture Measurement: Non-Contact NIR Moisture Sensors in Powder and Bulk Solids

Why Idlers fail: Quantifying the Effects of Idler Bearing Misalignment on Bearing Life

By G. Shortt Idlers are an essential component of every belt conveyor. They are a rather cheap mass­product which anybody uses, but (almost) nobody takes into account – unless they fail. Following you’ll find some explanation about the reasons of their failure. Continue reading Why Idlers fail: Quantifying the Effects of Idler Bearing Misalignment on Bearing Life

Conveyor Belt Monitoring: New Technologies for the Protection of Conveyor Belting

By A. van Staden In mines and many plants of the processing industry conveyor belts are the lifeline of the production system. It is, therefore, of paramount interest to keep the conveying system up and running and recognise potential hazards (far) ahead of their occurance.
