Learn MoreSemi-Autogenous Grinding (SAG) Mill. Wet or dry. Higher capacity thanA-G mill grinding. Primary, coarse grinding (up to 400 mm feed size) Grinding media is grinding feed plus 4-12% ball charge (ball dia.100- 125 mm) High capacity (short retention time) Less sensitive to feed composition (critical size material)
Learn Morerod ball mill closed circuitin kenya. EF2 – OpenCircuitGrinding – when grinding in opencircuit ball millsthe amount of extra power required compared toclosed circuit ballmilling is a function of the degree of control required on the product produced
Learn MoreSAG Mill, HPGR andBall Millin an ABCClosed Circuit. Instead of recycling the larger size fraction, the oversize product fromAG/SAG millsis sometimes prevented from discharging from the mill by using a reverse spiral at the discharge end and washes back into the mill for further grinding [4] .
Learn MoreAt least 15 to 20 kg sample material is required to simulate a closed grinding circuit in a ball or rod mill The Rod Mill Work Index RWI is used for particle size determination in a size range from 25 mm down to 21 mm whereas Ball Mill Work Index BWI is used for the range from 21 mm down to 100 m Adjustment of grinding parameters: View More Details
Learn MoreRod mills are used in an open circuit between crushing and the ball mill. They often operate in wet and where the pulp contains up to 50% solid by mass. This machine is equally very applicable to dry where it could take a feed that has achieved 6% moisture. As such, when the product is sticky, rod mills are preferred over ball mills.
