Primary crushers reduce large run-of-mine material, such as rocks and ore lumps, into smaller sizes for further processing downstream, whether that be transport to additional crushers or ...
Making iron and steel from iron ore requires a long process of mining, crushing, separating, concentrating, mixing, agglomeration (sintering and pelletizing), and shipping to steel mills. ... and feed mechanisms are therefore often dispensed with the trucks depositing their loads directly into the mouth of the primary crusher.
Primary Crushing. The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1. Feed: ROM up to 1.5 m; Product: -300mm (for transport) to -200mm (for SAG mill) Feed Rate: 160 to 13,000 tph
Gyratory Crushers. The gyratory crusher. provides a crushing chamber similar to the jaw crusher providing a progressive crushing cavity. The crushing action is provided through an eccentric that swings the bottom of the crusher mantle with respect to the bowl and concaves.
Innovation has an important role in improving the productivity, safety and sustainability of mining operations. Historically, ore transport was done by diesel trucks, but with the commitment to reduce CO2 emissions and increase mine safety, mining companies have invested in innovative, more sustainable ore transport technologies. …

The primary crushing process of an iron ore mine involves the use of a large jaw crusher or a gyratory crusher, which are designed to handle large rocks and ores. The crushing process begins with the ore being fed into the crusher, which uses a set of jaws or a cone to break down the material into smaller pieces.
Mining iron ore typically involves finding a fertile site, drilling and blasting the ore, and then transporting it to the primary crusher for processing. Crushed ore is sorted over screens and resized to different specifications (lump and refined products).
