Optimal and energy efficient operation of conveyor belt
Conveyor belt systems (CBSs) are used in a variety of industries for bulk material transportation, as outlined by Fedorko et al. ().It is a well-known fact that energy consumption of conveyor belt systems (CBSs) is lowered by implementing variable speed drives (VSDs) instead of fixed speed drives (Zhang and Xia 2010; Ristić and Jeftenić 2012; Hiltermann et al. 2011; Middelberg et al. 2009
Conveyor belt fire protection - July 2013 - Alien Systems
Conveyor belt fire protection is a specialised niche area where knowledge can be vague or hard to come by. Conveyor belt fires are not new: the March 1940 issue of Popular Mechanics published an article relating to a 20 mile gravel haulage conveyor system. It described the use of thermocouple hoods as means of detecting fire.
