Rubbers used in conveyor belt transport undergo an aging caused by the aggressive character of external environment during their operation. The main changes of conveyor belts due to the aging process appear firs tly on their surface being in an immediate contact with the cargo transported and/or with an ambient air. Chemical changes caused by the aging are reflected in changes of physical properties of belt components such as network density, glass transition temperature Tg and other. Determination of physical pro...

Conveyor belt slip on a driving drum belongs to dangerous accidents that may result in a fire and burning of the rubber belt cover and drum coating under not well described conditions. To prevent such situations temperature of the rubber coating is often monitored by optical methods. We argue that these optical measurements may not monitor the initial phase of belt slipping thoroughly enough and that they cannot predict the incoming danger. We propose to measure continuously the temperature gradient in the rubber ...
