A gyratory crusher is a type of primary crusher used in mining and ore processing operations. It consists of a concave surface and a conical head, both of which are typically lined with manganese steel. The inner cone has a slight circular movement, but doesn't rotate; this movement is generated by an eccentric arrangement. As the rock falls down from the feeding point, it gets crushed between the two surfaces by the gyrating action of the head.
Gyratory crushers are ideal for handling hard, abrasive rocks and materials. They can process large amounts of rock, making them suitable for heavy-duty mining and large-scale operations. They offer high throughput capacities and can be used for both hard and abrasive materials.
