Rod Mill

Introduction of Rod mills

Rod mills are used for rough grinding operations. A certain number of steel rods are loaded into the cylinder as the grinding medium for dry or wet grinding of various ores and other grindable materials. Rod mill is suitable for grinding various ores and other materials. It can be divided into dry and wet grinding methods. There are two discharge modes: central discharge and peripheral discharge.

Sinoma Liyang has rich experience in rod mill manufacturing. With complete specifications and wide applications, rod mills can well meet the needs of various mineral processing. The diameter of the rod mill of Sinoma Liyang ranges from 2.1m to 4.5m, and the maximum power is up to 2200KW. Our product R & D team is constantly improving the design of rod mill and optimizing the scheme according to the specific needs of customers, so as to provide more reliable, safe and efficient equipment.

Working Principle:

The material enters the cylinder from the center of the feed end cover through the feed part. The motor drives the rotating part equipped with grinding medium (steel rod) and materials to rotate through the transmission device.

A certain grinding medium (steel rod) and materials are installed in the cylinder. Under the action of centrifugal force and friction, the grinding medium and materials are lifted to a certain height with the rotation of the cylinder and fall in a falling state.

The materials in the cylinder are crushed by the impact of the steel bars and the additional crushing and grinding stripping between the steel bars and between the steel bars and the cylinder liner, fully expose the fresh surface and get fully mixed. Finally, the ground qualified materials overflow freely through the center of the discharge end cover or discharge along the ore discharge port around the cylinder to complete the grinding process.
