Study on Wear of Scraper Conveyor Chute [PDF]
Advances in Intelligent Systems Research, 2015 The wear of the middle trough of coal mine scraper conveyor, is a common fault of scraper conveyor. Starting with the causes of wear by analyzing the structure and the working condition of the chute, it indicates that the friction is the main cause of the chute wear, and abrasive wear, adhesive wear, fatigue wear and corrosion wear are the main forms ...

A Concept of Automatic Tuning of Longwall Scraper Conveyor Model [PDF]
Annals of Computer Science and Information Systems, 2016 The modeling of machines and their operation modes is a key approach for optimization of their performance as well as for avoiding unwanted operational states which may lead to the occurrence of faults, and finally, to the breakdown. The developed model of a machine should be always parametrized, i.e. the certain number of parameters should be selected
