Abstract
PURPOSE: To avoid the trouble of a bowl mill for crushing solid matters such as coal by detecting whether an abnormally large amount of solid rocks and stones and tramp iron is contained in the solid matters as crushing object to be supplied thereto.
CONSTITUTION: A journal 22 is projected on one end of the rotary support 9 for supporting the roll 6 which cooperates with a rotated bowl to crush coal or the like, and a displacement meter 21 consisting of a magnetic core 23 and a coil 24 to detect the rotation angle of the pin 8 for bearing said rotary support 9 is attached thereon. Said displacement meter 21 is connected to an AND circuit 34 by a differential displacement meter amplifier 25, a high range filter 26, a first Schmidt trigger circuit 27 and a mono-multivibrator 28. In the meanwhile, a shunt resistor 30 for detecting the current of a bowl driving motor 4 and converting said current into low-voltage output signals is provided and connected to said AND circuit 34 in similar manner. Thereby, the bite of tramp iron is detected and warning is emitted.
