A crusher, also known as a stone crusher, is a machine that uses mechanical action to break large rocks, ores, or other raw materials into gravel or rock powder. Crushers are widely used in ore crushing, aggregate production, construction waste recycling, and natural stone processing.
In iron ore mining, the primary crusher must be capable of handling a feed size of up to 1,500 mm, depending on the type of crusher used (jaw, gyratory, or impact). Proper selection and sizing of the primary crusher are critical for ensuring high throughput, minimizing maintenance issues, and reducing the size of the ore to a manageable level ...

Before selecting an exact crusher, it is important to first consider what crushing technology is needed for the feed material. The two main methods used for crushing are fracture by energy or impact and compression or shear breakage.
Crushers are key equipment in mining, construction and aggregate industries. They break large rocks, ore, or other materials into smaller, more usable pieces. This equipment reduces the material by means of compressive force, impact, attrition or shear that are specific for the type of crusher being used.
