Rods. Rod mills are similar to bar mills at the front end, but the finishing end is different. Rods have a smaller section ( to 15 millimetres in diameter) and are always coiled, while bars are normally shipped in cut length. The final rolling in rod mills often takes place in a closecoupled set of 10 pairs of small rolls (200 and 150 ...

Besides, the liner of the ceramic ball mill is made of ceramic material. Rod mill. The rod mill is a kind of mill with steel rod loaded in the grinding body, which is often used as a firststage milling machine. When the rod mill works, the area between grinding medium and raw material is mainly changed from surface contact to line contact.

A Rod Mill has for Working Principle its inside filled grinding media, in this case STEEL RODS. These rods run the length of the machine, which is most commonly between eight and sixteen feet in length. The diameter of these rods will range from, when new, between two and four inches. The rods are free inside the mill.

The rod mill uses steel bars as the grinding medium, and the materials are in point contact during the grinding process. Therefore, compared with the energysaving ball mill, the rod mill has the characteristics of uniform ore discharge, which is suitable for production lines that require more uniform particle size, such as the rod mill grinding quartz sand, sand making and other production lines.

The main difference between a rod mill and a ball mill is the grinding medium. Rod mills use long steel rods as the grinding medium, while ball mills use steel balls. Additionally, rod mills are better suited to handling larger feed sizes, and they create a more uniform particle size distribution than ball mills.

The water can wash away the fine particles in time to avoid overgrinding. The wet ball mill has a low noise, and low environmental pollution. The wet ball mill has a simple transportation device with less auxiliary equipment, so the investment is about 5%10% lower than that of a dry ball mill. The grinding particle size is fine and uniform.
