In order to achieve this, it is crushed into a predetermined range of size at the site, so that reuse of resources can be achieved in a state where costs can be reduced while facilitating construction as much as possible.
In such a crusher, the material to be crushed is fed into a hopper using a working machine such as a hydraulic excavator, and is conveyed by a feeder and supplied to a crusher (crushing device). After being crushed, the paper is discharged and conveyed outside the apparatus by a discharge conveyance body such as a belt conveyor. In this case, in order to smoothly crush the object to be crushed, it is required that the supply speed of the object to be crushed by the feeder to the crusher is balanced with the crushing speed in the crusher. It is known that a detecting means for detecting the amount of the object to be crushed is provided, and the feeding speed of the feeder is controlled in accordance with the amount of the object to be crushed by the detecting means (for example, Patent Document 1).
On the other hand, there is a known sensor that detects rotation or hydraulic pressure of a hydraulic motor that drives a crusher, and when the sensor detects that the load is high, the feeder is stopped or decelerated. (For example, patent document 2).
Furthermore, it is known that the amount of the detected object to be crushed is notified to the outside, and this is notified to an external operator who is supplying the object to be crushed to the hopper so as to encourage the work to supply the object to be crushed. (For example, Patent Document 3).
