FIELD: equipment for grinding of materials.
SUBSTANCE: group of inventions relates to equipment for grinding materials, which can be used in unloading and loading trunnions of drum mills. Modular element is made in the form of ring 1, having at the side of working surface at least one rib 2. At that, ring 1 is solid, and rib 2 is located on working surface so that its base in reaming forms parallelogram, tops of which lie on opposite sides of working surface of ring 1. Trunnion lining contains interconnected rings 1, having on the side of working surface at least one rib 2, which forms single-thread or multiturn helical surface with ribs of adjacent rings. Neighboring rings 1 are in tight contact with each other by end surfaces, and ribs 2 of adjacent rings 1 are in tight contact with each other.
EFFECT: lining of trunnion ensures elimination of zones of turbulence due to continuity of profile of helical rib along entire screw surface of lining.
