SAG mills use a combination of steel balls and rock particles as grinding media, while AG mills use only the ore itself. Both types of mills are used for grinding ore in mineral processing operations, but SAG mills are larger in size and can grind larger quantities of ore. AG mills, on the other hand, are smaller and are typically used for ...

An estimated consumption of steel grinding media of around 600,000 tons in the 1980s already gives an indication of the scale of the problem (Malghan, 1982). Likewise, in the cement industry, as mills are supplied for ever increasing capacities, the ball size distribution and wear exact a tremendous effect on the profitability of producing ...

However, the actual amount required for a particular ore would probably be different. For example, in a sulfide concentrator, addition of lime to the pyrrhotite regrind mill reduced ball consumption by 40%. The lime was added at kg/t of ore which changed the feed pH = to discharge pH = Composite Materials for Ball Mill Liners

SAG mills and calculated the wear rate exponent to be This implies that SAG balls wear fastest at their full size and wear progressively slower as their mass is decreased. Accepting a wear exponent of for SAG mills is valid when describingthe ball's wear when the ball isstillrelatively large [>75mm (3 in.)]. However, a wear rate ...

When one end wears out, switch to the opposite end for two times the life of a standard carbide end mill. Made of solid carbide, these end mills are harder, stronger, and more wear resistant than highspeed steel and cobalt steel for the longest life and best finish on hard material. Use them to round sharp corners on the edge of your workpiece.

There are basically two groups of Grinding Mill Liners. Ones with a HIGH PROFILE and those with a LOW PROFILE. The high profile liner is designed to give the media the higher lift. This type will be used in mills that are designed for primary grinding and as a result require the impact of the higher cascade. Ball mills working as the secondary ...

Ball mill design consists of feeding part, discharging part, rotary part, transmission part (reducer, small gear, motors, electrical control) and other major parts. Hollow shaft is steel castings, and the liner is detachable. Rotary gear is processed by casting hobbling. The cylinder is lined wearresistant liner plate with good resistance to wear.
