A survey of a SAGball mill circuit processing ore from primary crushing showed size reduction of circuit (SAG) feed F 80 of approximately 165,000 µm to flotation circuit feed (cyclone overflow) P 80 of 125 µm The total specific energy input for the two milling stages was 146 kWh t −1 Calculate the operating work index for the circuit

BUILDING A SOLID FOUNDATION FOR YOUR MILL The grinding mill is at the heart of a mining operation, but a poorly designed or constructed foundation will not only affect grinding mill performance but potentially render the mill out of action – thereby costing millions of dollars in lost production The following advice will help ensure the foundation is right before you install a new mill

HOW TO ENSURE SEISMIC REQUIREMENTS FOR SAG AND BALL MILLS Dr Axel Fuerst, ABB Switzerland, Baden, CH David Casado, ABB Switzerland, Baden, CH Reinhold A Errath, ABB Switzerland, Baden, CH Abstract The recent seismic events have shown that earthquakes have an immense destructive power Chile was hit in February 2010 with a seismic intensity of 88 on the

Although the foundation of the test was based on his practical engineering experience, it was in collaboration with Dawson Metallurgical Laboratories and Outotec that the SAGDesign test was developed The test consists of a robust laboratory SAG test followed by a Bond Ball Mill Work Index test on SAG ground ore (referred to as S dBWI) We offer a wide range of consulting services including
