Abstract:

Steel media wear has been well studied and quantified; one method of quantification is the Comminution Dynamics Lab's Total Media Wear model. It combines simulations, abrasion and corrosion experimental trials to determine wear for the components of milling and grinding ores and minerals for the mining industry. Breakage is an important measure of process efficiency, the greater the number of breakage events per unit energy consumed, the greater the throughput and production. The classic breakage parameter, the Bond Work Index generates an energy term used by mill operators to determine thi

Abstract:

In mineral beneficiation, grinding is used to reduce the size of the ore particles, generate larger surface area, and liberate valuable components. Grinding represents the most energy consuming stage of the process. Continuous research has aimed to increase the rates and efficiencies of milling by predicting the behaviour of large industrial mills, for example, through an examination of energy-size relationships and by using population balance models. The input for these models comes from data extracted from small laboratory-scale mills or impact tests. However, these breakag

Abstract:

Huge amounts of energy expended on comminution devices, such as ball mill, besides being a highly inefficient process has been the motive of much research aiming at improving the efficiency of comminution processes. Comminution theories are mainly based on size distribution of the ore and consequently fall short in addressing other imperative phenomena, such as media wear and more importantly energy utilization efficiency. A methodology based on an energy viewpoint is proposed for comminution studies which can serve as a powerful tool in design and performance optimization of comminution devic

Abstract:

Robots that can be reconfigured to perform more than one task would be to consumers. The Four-Wheel Independent-Drive, Four-Wheel Independent-Steer (4WD4WS) robot is well suited for the role of reconfigurable robot due to its extremely high maneuverability and torque control. However, the nonlinear dynamics in conjunction with complex kinematic constraints make the 4WD4WS structure an extremely difficult control problem. As a result of this many who model the 4WD4WS structure make simplifications that aren?t realistic for a reconfigurable consumer robot. A 4WD4WS robot is kinematically and dyn
