A compressing machine includes a press unit for compressing a concentrated sludge within a squeezing chamber to provide a briquette, and a press control unit to control the press unit. The press control unit includes a parameter and compressing speed setting unit, a parameter measuring unit, and a compressing speed control unit. The parameter and compressing speed setting unit is a unit in which a relation between a predetermined parameter that may affect compression performed by the press unit, and a compressing speed of the press unit. The predetermined parameter may include a coolant temperature, ambient temperature or a coolant content and others. The parameter measuring unit is a unit to measure the predetermined parameter. The compressing speed control unit controls, based on a result of measurement by the parameter measuring unit, the compressing speed of the press unit in accordance with a content set in the parameter and compressing speed setting unit.
A grinding sludge compacting machine to compress and make a briquette of a grinding sludge by inserting a concentrated grinding sludge formed by filtering a grinding sludge, produced in a grinding line by grinding hardened component parts while containing a coolant, into a press unit comprising a cylindrical mold fixed on a machine bench, a first piston reciprocatingly movably inserted in the cylindrical mold and a second piston arranged in face-to-face relation with the first piston, and compressing the concentrated sludge;
