In the case of crushing sand in a rod mill, a product of a first-stage crusher called a crusher run (roadbed material, size 40 mm or less, of which 15 to 30% is 5 mm or less) is passed through a rod mill, and the mill product is sieved by wet milling.
Read MoreThis type of mills is used to produce products of coarse particles of less than 1 to 5 mm in diameter. You are able to run these mills with elimination of troubles such as sticking or bridging as not only pre-mill to the dry-grinding ball mill but also fine grinding mill for wet coke and ores, and others.

Read MoreRod 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.

Read More9/1/2019· Chapman et al. (2013) compared the effects of using different circuits HPGR (dry) -rod mill (wet) and cone crusher (dry) -rod mill (wet) on the flotation of base metal sulfides. They indicated that apart from the grinding environment, HPGR could produce finer particles than a cone crusher. This difference was higher in the fully dry system.
Read MoreThe super-fine crusher generated higher liberated magnetite minerals in the 300 + 212 µm and < 45 µm size fractions compared to rod mill. Both comminution devices generated large low-grade hematite and goethite middlings. However, the rod mill produced higher locked/unliberated hematite and goethite compared to that of the super-fine crusher.

Read MoreRod mills are an efficient crushing machine for grinding various materials into powder. Rod mill crushes generally coarser than those produced in Ball mills, and rod mills are well suited to handle coarser feed and to control the bigger size of the product. Rod mills have Type RO, RE and RC depending on different purposes.

Read MoreThe 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).
Read MoreIn this study, the mineralogical and physicochemical characteristics of crushed magnetite ore using the IMPTEC super-fine crusher have been investigated in comparison with those of rod milling. The super-fine crusher generated higher liberated magnetite minerals in the 300 + 212 µm and < 45 µm size fractions compared to rod mill.
