To provide a wear evaluation method in piping system for transporting ore slurry capable of easily and quantitatively evaluating relative wear on each component in a piping system for transporting ore slurry, a wear evaluation device, and an ore wear measurement device used therefor.SOLUTION: The ore slurry transportation piping system is provided with multiple movement speed measuring means 11 at multiple points for measuring the movement speed of ore 52 included in ore slurry 50. Wear of a component positioned between the multiple points is evaluated on the basis of a difference of movement speed of the ore 52 measured by movement speed measuring means 11 at multiple points.SELECTED DRAWING: Figure 1 【課題】スラリー輸送用配管系の構成要素毎の相対的な摩耗を簡便かつ定量的に評価できる鉱石スラリー輸送用配管系の摩耗評価方法及び摩耗評価装置と、それに用いる鉱石の摩耗度測定装置を提供すること。【解決手段】鉱石スラリー輸送用配管系の複数箇所に鉱石スラリー５０に含まれる鉱石５２の移動速度を計測する移動速度測定手段１１を設け、移動速度測定手段１１により計測される鉱石５２の移動速度の複数箇所における差に基づいて、複数箇所の間に位置する構成要素の摩耗を評価する。【選択図】図１
