Ball Mills. Ball mills have been the primary piece of machinery in traditional hard rock grinding circuits for 100+ years. They are proven workhorses, with discharge mesh sizes from ~40M to <200M. Use of a ball mill is the best choice when long term, stationary milling is justified by an operation. Sold individually or as part of our turn-key ...

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

Some of the major findings from the study were as follows. HPGR energy consumption (kWh/t) was 38% of the ball mills. With all the different auxiliary equipment, HPGR total circuit energy usage was still less than 50% of the ball mill circuits. Fines removal from HPGR feed increased grinding efficiency in the compression zone by 25% …

In 1998 the world's largest SAG mill and two of the world's largest ball mills were commissioned at Newcrest Mining's Cadia Hill property in New South Wales. The design of the comminution circuit and selection of mill sizes followed two years of study and evaluation of a wide range of alternatives, predominantly using simulation techniques.

Increasing the size of the mills, however, meant that Cadia would need to use mills of unproven design {40 ft x 20 ft (12.2 m x 6.1 m) SAG mill and 22 ft x 33.5 ft (6.7 m x 10.2 m) ball mills}. There was considerable concern about taking this step, as many saw this as a risky option in the Cadia Feasibility Study performed by Fluor Daniel-Davy.

The autogenous mill will grind the material to the extent that the content of the particles with particle size <0.074 mm accounts for 20–50% of total quantity of product, and crushing ratio is 4000–5000, which is over 10 times that of ball mill and rod mill. The maximum particle size of the lump ore fed into autogenous mill is 300–350 mm.
