It is mainly for medium and fine crushing of challenging, brittle components. There may be one more form dry rod mill. In order to prevent the dangers of in excess of crushing, rod mill is usually used by re-election or magnetic separation plants of tungsten tin mineral and various rare mineral.
When using two grinding process, if the first step grind products from twenty ~ six mm to 3 ~ 1mm, adopts rod mill for that initial step grinding rod mill, the production capacity will probably be larger ,and efficiency be increased too.
In some instances, rod mill can replace quick head cone crusher and do finely grinding. When coping with softer or ore that is not also tricky (particularly the ore is with huge viscosity), rod milling will grind the ore from 19-25 mm (or perhaps 32 mm) to 6-10 mm, with lower price in addition to a less complicated device in contrast with short head cone crusher. And might also make the workshop dustless and simplified.
The motor drives the rod mill via the reducer and peripheral huge gear, or the low-speed synchronous motor immediately drives the rod milling machine/mill as a result of big gear about rod milling machine to drive the cylinder entire body rotation. The cylinder body is full of appropriate grinding medium - steel bar.
From the function of centrifugal force and friction force, the grinding medium was promoted to a particular height, and after that was thrown or relief in fall state.
The elements to get grind had been continuously send in to the cylinder, and shattered through the moving grinding medium inside, Then, via the overflow and constant feed
