Fine crusher is also known as tertiary crusher, which is widely used for the fine crushing of granite, basalt, limestone, pebble, cement clinker, quartz, iron ore, bauxite and other minerals.
Impact crusher can deal with the coarse, medium and fine materials (granite, limestone, concrete, etc.) which have less than 500mm side length and less than 350MPa compressive strength.
Tracked jaw crusher is mainly used for hard rock crushing, aggregate production, open pit mining, waste crushing and recycling, cement production, tunnel broken, etc.
