gold mining control milling in a metallurgical plant

Jan 01, 2005 1. Background. For the past 100 years the key element in the processing of gold ore has been the cyanidation process. Over the years steady improvements have occurred in equipment design milling has evolved from stamp mills, through tube mills and ball mills to the large semi-autogenous grinding SAG and fullyautogenous grinding FAG circuits in modern gold plants.

Milling Process Defects Equipment

Milling is the most common form of machining, a material removal process, which can create a variety of features on a part by cutting away the unwanted material. The milling process requires a milling machine, workpiece, fixture, and cutter. The workpiece is a piece of pre-shaped material that is secured to the fixture, which itself is attached ...

ElastoDynamic Model of Robotic Milling Process

In this paper, a reduced elasto-dynamic model of the robotic based milling process is presented. In contrast to previous works, it takes into account the interaction between the milling tool and the workpiece that depends on the end-effector position, process parameters and cutting conditions spindle rotation, feed rate, geometry of the tool, etc..
