FIELD: machine building.
SUBSTANCE: in the colloid mill casing the actuating elements (1, 2) are installed coaxially with clearance between them with possibility of relative mutual rotation. The mill contains adjustment unit for clearance (5) between the actuating elements. The actuating elements material contains two or more components, and is characterised by hard strength matrix and presence of nodular soft inclusions with size 1-100 mcm.
EFFECT: invention increases operation life of the actuating elements under conditions of increased cavitation, and their simple manufacturing process.
