Rod Mills may be considered either fine crushers or coarse grinding equipment. They are capable of taking as large as 2″ feed and making a product as fine as 3548 mesh. Of particular advantage is their adaptability to handling wet sticky ores, which normally would cause difficulty in crushing operations.

Results reveal that H 2 O 2 was formed spontaneously when the ore was ground in the ball mill. The amount of H 2 O 2 generated increases with an increased pyrite load to the ball mill. Grinding with mild steel shows a lower measurable concentration of H 2 O 2 in slurry relative to grinding with stainless steel balls. This appears to be in ...

Final comminution of both hard and soft ores is often accomplished by grinding operations using media such as balls or rods of various materials. Grinding is most often performed with an ore/water slurry, which reduces particulate matter (PM) emissions to negligible levels. When dry grinding processes are used, PM emissions can be considerable.
