Primary crushers are solidly built to receive large lumps of rock directly from the mines and designed for large tonnage throughputs. Basically, gyratory crushers consist of a fixed solid conical shell or bowl (also called concaves) and a solid cone within the bowl called a breaking head (Figure 5.1).The breaking head is fixed to a central spindle, which is …
Gyratory Crushers. Gyratory Crushers are an excellent choice for a primary crusher, as they can handle very hard and abrasive material. They are ideal for dry to slightly wet material but not sticky material. Gyratories are compression crushers primarily used for heavy mining and quarried materials in extremely high tonnage applications.
Gyratory Crushers Gyratory crusher is generally used as a primary crusher. The crusher is popular due to its high throughput capacity and the large sized opening. The crusher is well suited for handling direct feed from haul/dump trucks. The gyratory crusher is mainly used in rock that is abrasive and/or has high compressive strength.
