Another type of secondary crusher has been developed which follows large primary ~~Shers to produce media for pebble mills.
The processed ore size defines the type and position of each stage. For instance, the primary crushing stage receives the extracted iron ore directly from the mine, where the iron ore diameter may reach 1 m. In the quaternary crushing stage, the size of the ore that feeds the crushers is less than 20 mm. Screens classify the ore by size and ...
Secondary crushers crush materials in the size range of 50 mm to 300 mm, which is determined by the type and size of the crusher. They produce output sizes from 6mm to 100mm. Secondary crushers can be divided into three main types: cone crushers, roller crushers, and impact crushers.
