Product Description

Grinding rods are used as grinding media in rod mills. During the service process, the regularly arranged grinding rods work in a cascaded manner. The grinding rods make the minerals in the gaps grind to qualified by impact and squeezing with the size reduced. When rods be attrited to specified size,it will be taken out of the mill.During the operation, if the toughness is insufficient, the rods is likely to break due to frequent impact.Once the broken rod occurs, the regular order of rods in mill is changed, then cause more broken rods. Therefore, the occurrence of broken rods not only seriously affects the grinding efficiency, but also causes damage to the equipment even shut down, and affecting the normal production.

The production of grinding rods is usually heated by medium frequency induction. At present, the commonly materials for rods are40Cr and 42CrMo, which mainly used mold steel, It has good toughness and uneasy to break. However, for large-sized grinding rods, the hardening layer is very shallow, only 8- 10mm. The wear resistance is poor,just like 65 Mn steel. Japanese scholars have proposed the material of high carbon steel as wear-resistant steel, which has a good effect, but it is strict on the production process, and high carbon steel is prone to metallurgical defects. For less rod material type, Goldpro has developed a new type of steel for grinding rod and matching heat treatment process to ensure the grinding rod with higher toughness and  deeper hardened layer. Now,Goldpro’s rods are used in many mines and no broken.The wear rate was low and the grinding effect was remarkable.
