China Rod Mill For Iron Ore Application:
Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh). Grinding action is by line contact between the rods extending the length of the mill. Rods tumble and spin in roughly parallel alignment simulating a series of roll crushers. This results in preferential grinding of coarse material and minimizes production of slimes.

 

1. In the gravity and magnetic mining processing, the rod mill is used to prevent over grinding.

2. Pre-grinding. Rod mill is often used in primary grinding to grind material to 1-3mm with high efficiency. It could prepare fully for the next grinding.

3. To replace fine crushing. When processing soft or sticky ore, rod mill is used to replace fine crushing, which could effectively prevent crusher sealing material.

4. Artificial sand making,it is also one type of sand making machine.
