Rod Mill

What is Rod Mill?

Rod mill can be divided into dry rod mill and wet rod mill. Different from ball mill, built-in rod mill is a steel rod type grinding body, using the centrifugal force generated by the cylinder gyratory rotation, the steel rod will be lifted to a certain height and then thrown down to the ore for impact crushing, so as to achieve the grinding effect. Rod mill can also do fine crushing work to deal with softer or higher hardness ore, simple configuration, low cost, can be 19-30 mm ore better grinding to 6-10 mesh.

The product size performance of a dry rod mill in an open circuit milling operation is almost equal to that of a ball mills in a closed circuit milling operation.

If you are a beginner and do not know about Rod Mill, tell us your raw material characteristics, finished product requirements, site conditions, production budget, hourly production, and other requirements, we have professional engineers to equip you with a suitable model at a reasonable price. Next, let’s see the types of Rod Mill we can supply.

What Is Dry Rod Mill Used For?

Rod mill is used as the initial open circuit grinding, suitable for nonferrous metal, ferrous metal, nonmetal ore dressing site and chemical industry, building materials and other industries grinding materials to use.

For example: ①. Dry rod mill in a foreign sand and gravel plant processing plant, mainly responsible for open circuit grinding operations, feed size 45mm, discharge size 0.21mm, capacity of 150t/h, the overall effect is good, strong processing capacity, the current customer response all good.

②.A foreign mineral processing plant, the grinding system out of the ore containing water and mud, particle size difference is too large, in the case of a section of the open circuit, the grinding efficiency is relatively low, the quality of the material is relatively poor, far from reaching the intended target, so the selection of Chunlei’s wet rod mill, the rod mill because of the conical section of the cover with a small curvature, the steel rods rule the movement of the steel rods to grind the size of the steel rods is more uniform. The final solution to the problem of the mineral processing plant, so that the mineral processing work is efficiently completed within the specified time.

Working Principle of Rod Mill

The rod mill is driven by an electric motor through a speed reducer and peripheral large gear deceleration drive or by a low-speed synchronous motor directly through the peripheral large gear deceleration drive, driving the cylinder rotary. The cylinder is equipped with appropriate grinding media – steel rods. Under the action of centrifugal force and friction, the grinding media is lifted to a certain height and falls down in the state of throwing or draining. The material to be milled enters the inside of the cylinder continuously from the feed opening, is crushed by the moving grinding media, and the product is discharged out of the machine by the force of overflow and continuous feeding for the next section of the process operation.

Advantageous features of Rod Mill

• Rod mill features in the grinding process, steel rods and ore direct contact, with a certain selective grinding effect.
• The conical end cap of the rod mill has a small curvature, which enables the steel rods to move regularly in the mill, and is not easy to be clogged, with high production efficiency.
• The product size is uniform, less over-crushing phenomenon.
• The fineness of the discharged material can be adjusted, the coarse particles are polished first, and then the smaller ore particles are ground, so the danger of over-crushing is reduced.
• The diameter of the hollow shaft of ore discharge is larger, which is convenient for maintenance, and at the same time, it can reduce the liquid level of the pulp and discharge the ore quickly.
• The rod mill internal steel rod device is wear-resistant and has a long service life.
