Copper Grinding Mill For Sale

The rod mill, a tumbling mill characterized by the use of rods as grinding media, grinds ores, coal/coke, and other materials for both wet and dry applications. The rod mill accepts feed ore as coarse as 1 1/2” top size although better performance is obtained by restricting ore feed size to 3/4”. Product sizes range from 4 mesh to 16 mesh operating in open circuit, or as fine as 35 mesh operating in closed circuit with a screen or other sizing device.

Materials too wet for fine crushing and dry screening may be wet ground in a rod mill. Practice has demonstrated the ability of a rod mill to dry grind damp materials that will pack or plug other grinding equipment.

Rod Mill for Copper Processing Production

Rod mills have been used as the first copper grinding stage after crushing in copper beneficiation circuits. The rod mill product was further ground in ball mills before separation of copper concentrates from the host rock. With the advent of semi-autogenous (SAG) mills replacing secondary and tertiary crushing as well as first stage grinding, the rod mill has fallen out of favor for new large mineral beneficiation circuits.

Copper Processing Grinding Mill

After priamry crushing, the crushed copper ore will be delivered by conveyor system into a fine ore bin, from where it fed two identical line of grinding. Each line consisted fo a rod mill in open grinding circuit, followed by a primary ball mill in closed circuit with 508mm hydrocyclones and a secondary ball mill also in closed circuit. All ball mills were identical. the flotation feed size produced from this circuit is about 150microns.
