Title:
MOBILE CRUSHER AND CRUSHER CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/1996/022833
Kind Code:
A1
Abstract:
A mobile crusher and a method for controlling the same, wherein the rotation variation of an impact crusher is automatically refrained so as to obtain crushed substances having a desired particle size distribution. The crusher comprises actual rotation speed changing means (2, 3), an actual rotation speed detecting means (4) and a rotation speed setting means (7) for setting a target rotation speed Nm for the impact crusher (13) and rotation, speeds Na/Nb indicating start/stop of raw material supply for each target rotation speed Nm, wherein a control means (6) controls the crusher such that an actual rotation speed N coincides with a target rotation speed Nm and such that when an actual rotation speed N increases to a rotational speed Na, raw material is started to be supplied from a raw material supply device (14), while when an actual rotation speed N decreases to a rotation speed Nb, the supply of raw material is stopped.
