Sag and Tension Calculations Refinements and sagdesign

Traditional sag tension programs are for level ruling spans where low point sags sighted sags and mid span sags are one and the same In the real world spans are characterized by differencestesting measures the macro and micro ore hardness by means of a SAG mill test and a standard Bond Ball Mill Work Index test on SAG ground ore Ore feed is prepared from a minimum of 10 kg of split diamond drill core samples by stage crushing the ore in a jaw crusher to 80 product passing 19 mm The SAG test reproduces commercial SAG mill grinding conditions on 45 L of ore and determines the

Choosing a SAG Mill to Achieve Design PerformanceA discussion on the measurement of grinding media wear

SAG mill is an investment that can produce handsome returns if extra production is needed or simply to give the mine the option to mill the hardest ores at design throughput rat Typical tests required to define a hardness variability function are given below in Figure 1A survey found out that approximately 53 of the grinding circuits around the world use ball mills and 38 use autogenous or semi autogenous grinding and therefore nearly 90 of mining operations are users of balls as grinding media
