The vertical milling machine is a precision tool used for shaping and fabrication by the removal of stock typically from metallic work pieces. Plastics and other materials can also be machined on the mill depending upon tooling and material. Mill controls may be manually operated, computer numerical controlled (CNC), or a combination of both.
Outotec vertical stirred mills do the job for Kevitsa. In 2012, Kevitsa, a First Quantum (FQM) copper-nickel-platinum mine in Finland, began production with throughputs of about 5 Mt/y. The original scope included a grinding circuit consisting of two AG mills and a secondary pebble mill, with successive copper and nickel flotation to produce ...
achieve efficient grinding, closed circuit with hydrocyclones is needed. High cyclone efficiency greatly improves the performance of the circuit. A new procedure for Tower mill simulation and scale-up has emerged recently. Introduction The Tower mill is a vertical stirred grinding mill which can be used in both dry and wet grinding applications.
