Abstract:
A grinding sludge compacting machine for making a briquette of a grinding sludge by compressing a concentrated grinding sludge that is a grinding sludge which has been produced in a grinding line by grinding hardened component parts while containing a coolant and which is obtained by filtering the grinding sludge, said grinding sludge compacting machine comprising:a press unit having a squeezing chamber defined therein and operable to compress the concentrated sludge by application of a pressure within the squeezing chamber, and a press control means for controlling the press unit, said press control means including a parameter and compressing speed setting means in which a relation between a predetermined parameter that affects the compression by the press unit and a compressing speed of the press unit is set, a parameter measuring means for measuring the predetermined parameter, and a compressing speed control means for controlling the compressing speed of the press unit in accordance with a content set by the parameter and compressing speed setting means, wherein the parameter is at least one of a coolant content of the grinding sludge, a temperature of the coolant in the grinding sludge, an ambient temperature of the press unit, and a temperature of a predetermined portion of the cress unit.
