Abstract:
To suppress an excessive load of an element for driving a roll feeder following aperture adjustment in a crushing apparatus that conveys an object to be crushed by using the roll feeder adjustable in aperture.SOLUTION: This crushing apparatus comprises: a crusher; a hydraulic motor 37; a roll feeder; a position sensor 43; and a control device 41. The hydraulic motor 37 generates a rotary-driving force. The roll feeder has a conveyance surface and a feed roll 12. The feed roll 12 is rotary-driven by the hydraulic motor 37. An object to be crushed is held between the conveyance surface and the feed roll 12 and conveyed toward the crusher. The position sensor 43 detects an aperture which is a distance from the conveyance surface to the feed roll 12. The control device 41 reduces the rotation speed of the feed roll 12 when the aperture detected by using the position sensor 43 changes to be reduced.SELECTED DRAWING: Figure 2
