Grinding sludge compacting machine

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 predetermined parameter is a temperature selected from the group consisting of a temperature of the coolant contained in the concentrated sludge, an ambient temperature of the press unit and a temperature of a predetermined portion of the press unit and wherein the parameter measuring means measures said temperatures or the ambient temperature and, based on a result of measurement performed by the parameter measuring means, the compressing speed is controlled by the compressing speed control means in accordance with the content set in the parameter and compressing speed setting means.
