Gyratory Crushers 911 Metallurgist
Gyratory Crushers. The primary rock breaker most commonly used in large plants is the gyratory crusher, of which a typical section is shown in Fig. 5. It consists essentially of a gyrating crushing head (521) working inside a crushing bowl (522) which is fixed to the frame (501). The crushing head is carried on a short solid main shaft (515A 12×25 (1-car) gravel driveway costs $300 to $900, and a 24×24 (2-car) driveway is $600 to $1,800.
