To switch measurement of an abrasion loss from conventional manual work measurement to automatic measurement in order to make efficient measuring work of the abrasion loss under an inferior environment in a crusher, and in order to process a data efficiently using a computer.
In this crusher, a distance from a measuring part 2 to a mill table segment bottom face 1 in a measuring position (or angle) is automatically measured by a mobile personal computer 4, in abrasion in the mill table segment bottom face where severe abrasion is generated. A distance difference between the measuring part 2 and the mill table segment bottom face 1 before and after the abrasion is found in an inside of the mobile personal computer 4. An abrasion state is thereby allowed to be displayed in each position of the mill table segment bottom face 1.
