[0002] Cone crushers are widely used in mining, construction, metallurgy, chemical industry and other industries. In the mining field, they are used to crush ores of various hardness, such as iron ore, copper ore, limestone, etc., and break large pieces of ore into smaller particles for subsequent beneficiation, smelting and other processes. In the construction industry, raw materials such as rocks can be crushed into aggregates of different specifications for the production of concrete, asphalt mixture and other building materials. In the metallurgical industry, the ore is initially crushed to provide materials of suitable particle size for subsequent grinding and other processes.
