Grinding Rod

A grinding rod, also known as a grinding bar or grinding steel rod, is a cylindrical metal rod used in the mining and mineral processing industry for grinding ore to release valuable minerals. These rods are commonly used in rod mills in various mining operations. 

The grinding rods are made of high-carbon steel and come in different sizes and lengths. They are designed to withstand the impact and abrasion caused by the grinding process. The rotation of the rod mill causes the grinding rods to grind the ore by tumbling within the mill, breaking it into smaller particles. 

Grinding rods play a crucial role in the comminution process, where the ore is reduced in size through crushing and grinding for further processing and extraction of minerals.

How are grinding rods manufactured?

In factories, grinding rods are made by hot-rolling processes. These rods are made with special steel and varying alloy to enhance the performance and properties of the rods. They are hardened by micro alloying steel and heat treatments. Manufactured with the best and latest techniques, the dimensions can easily be altered according to the client’s needs. 

How are grinding rods transported? 

Grinding rods are typically exported by sea but can be transported in bundles by truck to job sites. A thorough checking process occurs before the steel is ready for export. In this process, a few things must be reviewed during packing and labelling. This may include quantity testing, quality testing, and weight etc.
