Manganese steel is known for its work hardening characteristic, meaning the more impact it takes, the harder the surface becomes. On the Brinell Hardness Scale, the product can reach a hardness score of 550 BHN through work hardening. Manganese is a cost effective solution for those applications that take severe beatings.
Once the ore is crushed to the appropriate size, it enters the grinding stage, where the manganese ore is refined into a fine powder using specialized equipment such as ball mills or vertical roller mills. To achieve this, various crushing equipment such as jaw crushers, cone crushers, and ball mills are commonly used to crush and grind the ore.
