The groove liner is provided with grooves on the inner side of the liner, and the arc of the groove is 90°-120°, which changes the point contact between the ball and the liner into a surface contact of 90°-120°. Our institute (Hefei Cement Design and Research Institute) is the first company to design and apply grooved linings. so far. It has been widely used in several mills in China.
and exported to dozens of countries such as Brazil, Indonesia, Thailand, Chile and so on. Features of Xinma grooved liner:
1. Targeted stand-alone design can be made according to the process parameters collected from the mill survey table, and the appropriate groove lining plate can be selected and produced.
2. Combining the groove lining plate with other structural lining plates: such as activated lining plate, annular groove lining plate, double helical groove lining plate, cone lining plate, retaining ring, etc., can realize wear-resistant steel balls The positive grading is produced, which is consistent with the grinding process of the material; the combined installation method can be fixed with bolts or inlaid. 3. Due to the groove-shaped structure, the contact area between the ball and the lining plate and the dislocation between the ball layers are increased, which improves the lifting effect of the lining plate, thereby improving the potential energy of the grinding body, increasing the crushing and grinding effect, and improving the Yield.
4. The groove type structure makes there always a material pad in the groove, which reduces the wear between the grinding blocks and reduces the metal bump between the grinding block and the lining plate.
