Predicting the overall specific energy requirement of

For tumbling mills the two indices relate to "coarse" and "fine" ore properties plus an efficiency factor which represents the influence of a pebble crusher in AG/SAG mill circuits "Coarse" in this case is defined as spanning the size range from a P 80 of 750 μm up to the P 80 of the product of the last stage of crushing or HPGR

USING THE SMC TEST TO PREDICT COMMINUTION

AG and SAG mills Ball mills Rod mills Crushers High Pressure Grinding Rolls (HPGR) POWER-BASED EQUATIONS General The approach divides comminution equipment into three categories Tumbling mills eg AG SAG rod and ball mills Conventional reciprocating crushers

Application Of Hpgr Mills In Iron Ore Processing

Application Of Hpgr Mills In Iron Ore Processing 2016-5-4also been applied in mineral processing plants largely in iron ore and diamond treatmentn these industries the application of hpgr ranges from coarse grinding e the grinding of 65mm 2 size excess pebbles in ag circulation loops to final grinding of 100m material to high blaine values in the preparation of pellet feed

Application of population balance model to HPGR crushing

The HPGR has been introduced to minerals industry as a replacement for tertiary crushers SAG mills and rod mills In some applications it appears as a pebble crusher in AG milling Interparticle breakage in the compression zone between the rollers is achieved by choke feeding the material to the HPGR otherwise the HPGR

CREATIVE AND SIMPLER HPGR CIRCUITS MAY INCREASE THEIR

between the gyratory crusher and the secondary crusher and HPGR • The secondary crushing circuit operates in closed circuit with screens to ensure a maximum top size of approximately 50 mm to each 2 4 m D HPGR • Plenty of surge capacity is provided between the ball mill and the HPGR to sustain constant feed to the
