Rod mill apply in grinding ore like ball mill, selecting use a ball mill or rod mill according to different working conditions. Generally speaking, coarse grinding for rod mill, fine grinding is suitable for ball mill, the reason is that the rod mill grinding media for steel bar, is a line contact, and the grinding media for ball mill, is a point contact, different ways of contact determines the different grinding particle size.
Rod mill is used less now, it mainly used in coal chemical industry of coal water slurry preparation, quartz sand, silica sand, sand aerated, tungsten ore, potassium sodium feldspar, bauxite, and other industries. The ball mill is well known and it is used more widely. But using rod mill is a trend. Now the using of the rod mill is more and more international, it may have a great relationship with the changes in the grinding process, the concept of more crushing less grinding is accepted by more and more people.
Rod mill is applied for triturating or crude crushing all kinds of ores with different grades and other materials by wet process, especially used for adjusting the for sand making. High-efficiency rod mill as modern equipment has been integrated into the real life of people. For example, high buildings, highway and high-speed railway have indivisible relationship with the rod mill.
Nowadays, domestic rod mill industry develops slowly. Most people used steel rolling round steel, round steel belongs to raw materials and used for wear resistant steel. It is obviously not scientific, because its hardness is low, only about HRC12 degree. Round steel internal profit not lift (easily broken bar); Round steel internal organization loose not tight and so on. Because of these defects, it can appear round steel used for grinding rod wear large steel rod (consumption), bend, rupture, winding, two head nozzle, low yield, short of expectations percent of pass, the follow-up issues of magnetic separation process workload big.
