1. Crushing and grinding equipment. The main purpose of crushing is to reduce the size of the ore particles for further processing while grinding is to obtain finer particles for efficient extraction. The process begins with an initial crushing stage, where large pieces of manganese ore are broken into more manageable sizes.
