The rod mill, a tumbling mill characterized by the use of rods as grinding media, is used for grinding ores, coal/coke, and other materials for both wet and dry applications. The rod mill performs best when making products having a top size of 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. 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”.
Rod mill, unlike ball mill, is the most effective, practical and reliable sand processing machine.In its cavity , a certain amount of steel bar or rod iron is filled to act as grinding medium,rod mill is named according to the grinding medium- rod iron.
Rod mill has two types to choose from ,the dry type and the wet type.Our company adopts advanced controllable material technology, combined with appropriate grinding media that is coordinate with the actual grinding materials,changed the traditional surface contact to line contact, thus to make the particles more uniformly,and the output higher.
The mill grinding body is the main motor power 800kW of 23, to 19.2r/min speed reducer 22,sand crushing plant the discharge casing 21 and export hollow shaft 19 driven rotation. Grinding cylinder body equipped with every other board positions 9, 11 and 13, the cylinder is divided into four chambers. Transition position double-diaphragm plate between the two positions, two, three positions three, four positions are based on cylinder of a warehouse built by the production of high-manganese steel corrugated liner is installed within the two positions are ladder liner 10, three or four positions within the inlay puzzle produced by alloy white cast iron corrugated liner (corrugated liner) 12 and 15. Shop between the cylinder and liner layer 3mm thick plywood, and some to pad a thin rubber sheet, and the other in order to prevent materials or broken grinding media to enter the the scour cylinder between the cylinder and liner, three, four positions small ripple between the liner and cylinder filling of asbestos cement. cement making machine:http://www.crusher-machine.com/cement-production.html

Rod Mill Applications:
1.It is mainly used for raw material processing and crushing,such as feldspar, quartz, ore, etc.It is also suitable for making abrasive, fire-proof material, cement, steel grit, slag powder, copper ore, iron ore, gold ore, concrete aggregate, asphalt aggregates and so on.
2.It is mainly for medium and fine crushing of hard, brittle materials.
3.In order to avoid the dangers of over crushing, rod mill is often used by re-election or magnetic separation plants of tungsten tin mineral and other rare mineral.
4.When using two grinding process, if the first step grind materials from 20 ~ 6 mm to 3 ~ 1mm, adopts rod mill for the first step grinding equipment, the production capacity will be bigger ,and efficiency be higher too.
5.In some cases,rod mill can replace short head cone crusher and do finely grinding.When dealing with softer or ore that is not too hard (especially the ore is with big viscosity ), rod milling will grind the ore from 19-25 mm (or even 32 mm) to 6-10 mm, with lower cost and a more simple device compared with short head cone crusher. and can also make the workshop dustless and simplified.
