Compared to the cone type crusher, a gyratory crusher has a crushing chamber designed to accept feed material of a relatively large size in relation to the mantle diameter. ... Iron ore operations commonly employ one or more stages of crushing with screening stages incorporated to remove material meeting product size specifications as …

Applicable materials: The compound crusher is suitable for crushing sandstone, limestone, cement clinker, iron ore, aluminum ore, molybdenum ore, phosphate rock, and other materials with medium hardness. Advantages: Discharging port: No grate and clogging. Material moisture: Materials with high moisture content can be processed.

The high-grade iron ore is defined in terms of iron content. In general, cut-off iron content of ROM for such type of ore is kept at approximately 55%, which is obtained by selective mining. The ROM ore is subjected to dry/wet processing through multistage crushing and screening for production of lumps (−40+10 mm) and fines (−10 mm). In the ...
