Rod Mill

Detailed introduction

The rod mill is a grinding equipment that uses steel rods as the grinding media, widely used in metal and non-metal mines, water conservancy, building materials, chemicals, refractories, metallurgy, glass, and other industries. This equipment adopts advanced controllable feeding and discharging technology, combined with actual grinding materials, and is equipped with suitable grinding bodies to change the traditional surface contact to line contact, resulting in more uniform discharge particle size and higher production capacity. Rod mills are available in both dry and wet forms for users to choose according to their actual situations.

Working Principle of Rod Mill

The working principle of the rod mill is to drive the rotation of the cylinder through the motor and the surrounding large gear reduction transmission. The interior of the cylinder is equipped with appropriate grinding media – steel rods. The grinding media is lifted to a certain height under the action of centrifugal force and friction and falls in a throwing or leaking state. The material to be ground continuously enters the interior of the cylinder through the feed port and is crushed by the moving grinding media. The product is discharged outside the machine through the force of overflow and continuous feeding for the next process operation.

Product Features of Rod Mill

1. High efficiency and energy saving: Advanced controllable feeding and discharging technology and suitable grinding bodies are used to make the discharge particle size more uniform and increase production capacity. At the same time, the equipment can use rolling bearing support instead of bush sliding bearing support, using dry oil lubricating grease instead of thin oil lubrication station, saving 10-20% of energy.

2. Superior particle shape: During the grinding process of the rod mill, the grinding media and the ore are in line contact, so they have a certain selective grinding effect. The product particle size is uniform, and there are few over-crushed ore particles. When processing coarse-grained materials, the processing capacity of the rod mill is larger than that of the ball mill of the same specification.

3. User-friendly design: The equipment adopts an automatic centralized lubrication system to avoid thin oil pollution, reduce equipment failure rate and operator maintenance costs, and improve the production efficiency of the whole machine.

4. Wide application: Rod mills are suitable for grinding operations of ores and rocks with different hardness (Mohs hardness 5.5-12), meeting the requirements of various ore crushing and artificial sand making operations. They are widely used in mining, water conservancy and hydropower, building materials, chemicals, and other industries.

5. Stable and durable: The main body of the rod mill is a low-speed rotating cylinder horizontally mounted on two large bearings, with a stable structure, smooth operation, and long service life.

6. Easy to operate: The equipment is simple and convenient to operate, easy to master. It adopts an automatic control system, which can realize remote monitoring and operation, reducing labor intensity.
