Henan Hongji Rod Mills

 

Applications:

Grinding of materials in a tumbling mill with the presence of metallic balls or other media dated back to the late 1800's. Henan hongji and its predecessor companies manufactured since 1968.

The rod mill, a tumbling mill charaterized by the use of rods as grinding media, grinds ores,coal/coke, and other materials for both wet and dry applications.

The rod mill accept 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 with a screen or other sizing device.

Material to 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 grin grind materials that will pack or plug other grining equipments.

 

Wet grinding rod mills:

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

 

Mill Liners

Among the case materials used for linings are Ni-Hard, chrome-molybdenum steel, and manganese steel. Rolled alloy steel plates with lifter bars is available.

Rod mill liners are subjected to severs impact. Premature breakage and scrap loss are reduced by correct selection of liners for the specific grinding duty. Additional benefit results from use of a backing material, such as rubber between the liners and the mill shell.
