SELF-GRINDING MILL LINING Russian patent published in 2025 - IPC B03B9/00 B02C17/10 B02C17/22 

FIELD: mining industry.

SUBSTANCE: invention relates to mining and can be used as a mill lining. Proposed is armoured lining of self-grinding drum mill with lifting elements made in the form of rods directed along the radius to the centre of the mill drum and located along it. Height of rods is determined by value of weighted average piece of ground material. Lifting elements are installed in rows equidistant to each other in longitudinal and transverse rows respectively. Longitudinal rows are inclined at angle of 0° up to 20° relative to mill drum generatrix in direction of its rotation. Transverse rows in intersection with longitudinal rows have angle of 90° up to 110°. Rods are made in the form of threaded pins with heads. One end of the rod is fixed on the mill drum, and a head is installed on the other end. Mats are pricked on rods, which are fixed on inner surface of armoured lining of drum mill with heads so that the armoured lining and rods are covered with mats. Heads are made of wear-resistant material and have the shape of truncated cones, the larger bases of which face the mats; at that, the head height is equal to 2/3 of the average weighted piece of the ground material.

EFFECT: reduced intensity of lining wear.
