In a process for wet crushing of hard substances, such as cement, concrete, limestone, coal, ores, ceramics, drilling mixes or medical mixes, in which coarse hard substances are introduced in a crushing device together with a liquid and are crushed to particle sizes of about 700 [mu]m to 20 mm and a slurry consisting essentially of crushed hard substances and water is discharged whereby 10 to 90% by weight coarse hard substances and 90 to 10% by weight liquid are introduced in a crushing and homogenisation device, the coarse hard substances are broken in at least one crushing and homogenisation step by using periodical shock pulses to particle sizes of about 1 [mu]m to 700 [mu]m and a homogenous fluid consisting of fine crushed hard substances and liquid is discharged as well as device for performing this process. |
