Unique massflow estimation technique for horizontal conveyor belts
Massflows on conveyor belts need to be measured in various process streams in mineral extraction processes to ensure good plant management. Conventional weightometers are, however, too expensive to allow a widespread installation in these processes. This study investigates more economic means to …

An Interactive Digital Manual For Safety Around Conveyor Belts In Surface Mining
Belt conveyor accidents are mainly attributed to negligence of safety procedures during maintenance work. Entanglement, falling from heights, & collapse of structure or loose materials are the main cause of accidents. While performing maintenance tasks such as cleaning, installation and repair, …

Design and construction of a vibration data logging prototype board for overland conveyor belts
Overland conveyor belt systems form a vital part of modern transportation systems in the mining and mineral processing industries. It is vital that the system is well maintained in order to minimise system downtime and maximise profit. The conveyor belt is the single most expensive item in the …

Conveyor-belts of information: the role of political parties in basic service delivery in Africa
… same. To illustrate political parties' role as Conveyor-Belts of Information, I focus specifically on two types of actors in these organisations – local party activists and elected representatives. First, using a panel survey of Zambian citizens I demonstrate that party activists and elected …

Introducing mobile robots on the automotive final assembly line : control, sensing and human-robot interaction
… in form of surfaces that are dynamic, i.e., the conveyor belts which ferry cars in the factory. I develop a control strategy to enable autonomous navigation on such dynamic surfaces, and design a sensing module capable of detecting the conveyor belts. The designed system is tested in simulation, …

Applications of risk pooling for the optimization of spare parts with stochastic demand within large scale networks
… of material handling equipment (MHE) such as conveyor belts. Unfortunately, this reliance on MHE means that failures could cripple an entire FC. The exceptionally high stock-out cost associated with equipment failure means spare parts must always available when required. This is made difficult …

Development of synthetic fiber-based reinforcements for thermoplastics as alternative to steel-based analogs for industrial applications
… such as escalator handrails and rubber conveyor belts. Due to their inherent creep accompanied by cyclic thermal expansion and contraction of steel cords, the overall stability and performance of the application can reduce over time. In this context, the present research focuses on an …

Vibration Attenuation of Composite Moving Beams using Active Vibration Control Techniques
… found in earthquake engineering, robotic arms, conveyor belts, etc. Previous studies have shown that the amplitude of lateral vibration of moving beams is 40 percent higher than that of non moving beams. In this research a numerical model based on the finite element method is done to reduce the …

Developing a flexible range sensing system for industrial inspection applications
… method suits range sensing applications where conveyor belts are involved. An in-depth study of the triangulation method is included. In the study it shows that this method also supports large depth-of-field range sensing. A dedicated signal processing hardware, built on the Micro Channel …

Improving Conveyor Belt Safety Training Through the Use of Virtual Reality
Working around conveyor belts is the cause of numerous accidents each year that are costly to the mining industry. Current safety training practices generally include the use of slide show presentations, lectures, videos, and paper material before sending each worker onto site with an experienced …

Energy efficiency and carbon dioxide emissions across different scales of iron ore mining operations in Western Australia
… energy efficient technologies such as overland conveyor belts, and advanced technologies including autonomous haulage trucks resulted lower energy consumption in medium scale mining operations. However, the energy consumed to mill and stockpile a unit of ore in medium-scale operations was high …

Transportation system selection in open-pit mines (Truck-Shovel and IPCC systems) based on the technical, economic, environmental, safety, and social (TEcESaS) indexes
… limit and transferred into the outside through conveyor belts. Although these systems are not new, they are mostly neglected as a transportation option basically due to the high capital cost and low flexibility. On the contrary, they can offer more environmentally friendly and safer working …
