Problems solved by technology
[0003] The corrugation of the existing ball mill cylinder liner does not pay due attention to how to reduce the wear and deformation of the peak part of the liner. Due to severe wear and tear, great changes have taken place, the height of the liner with the ball will decrease, and the efficiency of the ball mill to crush and grind materials will drop significantly.

Embodiment 1
[0015] Embodiment 1 sees attached figure 1 , the step-shaped cylinder liner of the ball mill in Example 1 of the present invention, the liner A is provided with a wave crest 1 and a wave crest 2, and the wave crest 1 and wave crest 2 are both step-shaped, and the wave crest 1 and wave crest 2 are composed of three The height H of the steps is greater than the radius of the small-diameter grinding balls, but smaller than the radius of the large-diameter grinding balls; the width M of the steps is greater than the radius of the small-diameter grinding balls.
[0016] See attached figure 1 , the working principle of the present invention is briefly described as follows: when a liner with two crests, each of which is composed of three steps, moves in the clockwise direction I, since the heights H of the steps in the crests 1 and 2 are equal It is larger than the radius of the small-diameter ball, smaller than the radius of the large-diameter ball, and the width M is larger than t...

The invention provides a stepped shell liner for a ball mill. Wave crests of the liner are stepped and one wave crest consists of at least two steps; the height of the step is greater than the radius of a small-diameter grinding ball and smaller than the radius of a large-diameter grinding ball; and the width of the step is greater than the radius of a small-diameter grinding ball. The stepped shell liner has a simple and reasonable structure, easy processing and manufacturing and capacity of effectively reducing abrasion loss of the wave crest for the shell liner of the ball mill, keeping excellent waveform of the wave crest, keeping the height of the ball-containing liner stable for a long time, keeping the smashing and grinding efficiencies of the ball mill stable for a long time, prolonging the service life of the liner in a large scale, effectively saving materials and electric energy, enhancing the yield, enhancing the product quality, reducing shutdown maintenance time and being used together with various models of ball mills, and is suitable for industrial production.
Description
technical field [0001] The invention relates to a cylinder liner of a ball mill, in particular to a stepped cylinder liner of a ball mill, belonging to the field of crushing and grinding machinery. Background technique [0002] The cylinder liner of the ball mill can be divided into a wave crest part and a bottom plate part. The main function of the crest part is to bring the grinding balls to a certain height so that the balls fall to a suitable position to crush and grind materials efficiently; the main function of the bottom part is to protect the cylindrical shell of the ball mill so that the cylindrical shell The body is not in contact with the mineral material and the grinding ball, so it will not be thinned by the mineral material and the grinding ball. The crest part of the cylinder liner is very important to the crushing and grinding efficiency and the output per machine hour of the ball mill. Therefore, how to ensure that the crest part of the cylinder liner is n...
