The crushers' components are of high strength design to accept high power draw. Manganese steel is used for both fixed and movable jaw faces. Heavy flywheels allow crushing peaks on tough materials. Jaw Crusher is widely used as primary and secondary crushing equipment to crush material with compression strength less than 320 MPa.
Iron ore processing involves several stages, starting from crushing and grinding to separating iron from the ore. Among the essential machinery used in this process is the iron ore processing crusher. This machine plays a critical role in reducing the size of iron ore, making it suitable for subsequent processing steps. Types of Iron Ore ...

The only processing steps used for ores mined from rich deposits (rich ores) are crushing and screening. These ore will be crushed and screened up to particles of about 8 -30 mm. Such ores come mainly from the weathering zones of itabirite deposits. ... The blast furnace is the outstanding type of equipment for the production of iron metal. The ...
Whether it is iron ore mined underground or open-pit, as long as the raw ore contains not high mud content, it can work effectively. Therefore, this process is a crushing process widely used in large and medium-sized iron ore …
Mining: crushing-grinding costs.Extracting useful resources from mined ores requires comminution. This is the integrated sequence of crushing and grinding operations, which breaks down mined rubble (3-10 cm diameter), effectively into talcum powder (30-100µm), which can in turn enter the metal refining process with sufficient surface area to extract the valuable materials.
In the circuit shown in the above picture, material passing over the screen, i.e. washed ore, is transported to the secondary crushers. Material passing through the screens is classified into coarse and fine fractions by a mechanical classifier or hydrocyclone or both. It may be beneficial to classify initially in a mechanical classifier as ...
