The Philosophy of Belt Tripper Automation

Modern mining is vitally concerned with the prompt, efficient movement of great quantities of bulk materials. It is not surprising, therefore, that intensive efforts are being directed toward improving effectiveness and reducing costs of materials handling systems. Historically, the operation of removing bulk material from a moving conveyor and depositing it in utilization or storage areas has been a high cost segment of the materials handling system. Since this operation is often performed by belt trippers, considerable attention has been focused on improvement of these devices. Frequently, the greatest opportunity for improving performance of these devices is the incorporation of remote or automatic control systems. This article describes tripper control systems developed by Kennecott Copper Corp. and explains the control philosophies used in designing these systems.
