Abstract

The invention provides a first bin lifting circular groove lining plate, which comprises mounting bolt holes. The axial direction of the surface of the lining plate is provided with U-shaped groove arcs (2); a small straight section (1) is arranged between each two U-shaped groove arcs; the radius of each arc is 35-100mm; the width of the corresponding arc is 30-120mm; the depth of the corresponding arc is 5-40mm; the number of the arcs is 2-6; and the width of each small straight section is 8-20mm. According to a structure adopted by the first bin lifting circular groove lining plate provided by the invention, the axial direction of the surface of the lining plate is provided with the U-shaped groove arcs, and the small straight section (1) is arranged between each two U-shaped groove arcs, the contact area of a steel ball is increased, and the lining plate is wear-resisting; a curve in the peripheral direction of the surface of the lining plate is an Archimedes curve, and thus, all points of the lining plate are equivalent in abrasion loss. Through controlling the thickness dimensions of both ends of the lining plate, arranging a concave-convex arc combination at the big end part of the lining plate and controlling the central position of a convex arc, a working blind area is eliminated, and the lining plate works at full area, and thus, the service life of the lining plate is prolonged, the work efficiency of a tube mille is increased, and energy and resources are saved.

Description

[0001] technical field [0002] The invention relates to a liner, in particular to a liner for a bin hoisting ring ditch. [0003] Background technique [0004] Generally, the working conditions of cement tube mill, coal mill tube mill and metallurgy tube mill: the temperature in the warehouse is high, and the working environment of the liner is harsh. During the working process, the points on the surface of the liner are in direct contact with the steel balls, and the contact stress on the surface of the liner is very large during the falling of the steel balls. The material and steel balls will cause a lot of chiseling and wear on the liner, and the service life of the liner is short, resulting in Liner material is wasted. Usually the inner arc surface of the liner is a pure arc surface, the surface of the liner is in contact with the steel ball during work, the contact stress and lifting angle of each point are different, and the wear of the liner has uneven thickness, ...
