iron ore concentration process pdf - webelmediatronics in Description High pressure grinding rolls HPGR technology is growing to be a common comminution tool in iron ore processing The technology finds a wide acceptance and presents specific benefits in coarse ore grinding and closed-circuit grinding in preparation of ball mill feed right down to the other end of the particle size spectrum
A mill is a device that breaks solid materials into smaller pieces by grinding crushing or cutting Such comminution is an important unit operation in many processes There are many different types of mills and many types of materials processed in them Historically mills were powered by hand (e g via a hand crank) working animal (e g horse mill) wind or water ()
Ball mill for the wet grinding of gold/copper ore in South Australia The grinding plant consists of an SAG mill of 10 4 m diameter x 5 18 m length with a 12 000 kW dual COMBIFLEX drive and a ball mill of 7 3 m diameter x 10 5 m length also with a 12 000 kW dual COMBIFLEX drive Dry grinding POLYCOM high-pressure grinding roll High capacity HPGR provides an excellent constant feed for down
Specifically the PPTs are being used to provide information for preliminary sizing and selection of an HPGR and to assess the effect of ore variability on HPGR performance The results are also applied to developing HPGR circuit designs and can be incorporated in simulation so that optimum design parameters can be selected
High pressure grinding rolls also called roller presses have been used in the treatment of iron ore copper (Fig ) gold diamond and various other ore types for many years Contrary to conventional crushing rolls the particles are broken by compression in a packed particle bed and not by direct nipping of the particles between the two rolls
Multiple trade-off studies have shown that grinding circuits with high pressure grinding rolls (HPGR) can be more energy efficient than the circuits with semi-autogenous (SAG) mills However such studies are difficult to conduct because the current practice of sizing and selecting the HPGR requires large samples for pilot-scale testing that are expensive and difficult to obtain There is
