FIELD: process engineering.
SUBSTANCE: lifting element is intended for mill drum using for ore and mineral crushing. Said lifting element is secured to drum frame to pass along drum lengthwise direction. Lifting element comprises flexible housing and anti-wear protection. The latter is arranged on housing front edge relative to drum rotational direction. Anti-wear protection consists of, at least, two different parts. Said parts are made from different materials with different impact strength and hardness. Anti-wear protection, if seen from lifting mechanism base, is divided into top and bottom parts. Said parts are located, in fact, one on the other. Top part of said protection is made from material with higher impact strength and lower hardness than those of bottom part. In compliance with other version, part of said protection made from higher-hardness material is arranged, partially, inside part made from high-impact-strength material.
EFFECT: longer life, simultaneous wear of mill drum, reduced power consumption, higher efficiency.
