TECHNICAL FIELD

[0001] The utility model relates to the technical field of ball mill, specifically a ball mill is with lining board. BACKGROUND

[0002] In the process of processing ore, it needs to use ball mill to carry out the crushing operation to the ore, as the important component of ball mill, the ball mill lining board is used to protect the cylinder of ball mill on one hand, makes the cylinder of ball mill avoid the direct impact and friction of grinding body and ore, on the other hand, the movement state of grinding body can be adjusted by using different forms of ball mill lining board, to enhance the crushing effect of grinding body to ore, which helps to improve the grinding efficiency of ball mill to ore. For the installation and fixation of lining board, the lifting strip is fixed on the inner wall of cylinder by bolt, in this process, the lining board can be clamped between the lifting strip and cylinder, and then the fixation of lining board is formed. But in the existing installation mode, the mutual restriction between bolt and lifting strip is not realized, and then the phenomenon of loosening of lining board and lifting strip can appear. Therefore, we provide a ball mill lining board to solve the above problems. SUMMARY

[0003] In order to solve the above problems, that is, to solve the problems raised in the above background technology, the utility model provides a ball mill lining board, which comprises a cylinder, a lining board, a lifting strip, a bolt and a nut, the lifting strip is fixedly connected with the cylinder through the bolt and the nut, and the bottom of the lining board is tightly pressed on both sides by the lining board;

[0004] The bottom of the lifting strip is provided with two trapezoidal grooves, the bolt is configured as a trapezoidal bolt matched with the trapezoidal groove, the side wall of the protruding block of the lining board can limit the lifting strip, and a plurality of limiting grooves are formed on both sides of the bottom of the lifting strip, and a limiting block matched with the limiting groove is integrally formed on the lining board.

[0005] Preferably, a sealing ring and a metal cover are sleeved on the outer wall of the bolt between the cylinder and the nut.

[0006] Preferably, the side wall of the bolt is provided with a press-in oil cup, and the input end of the press-in oil cup is provided with a cup cap.

[0007] The utility model has the beneficial technical effects that: the engagement of the limiting groove and the limiting block can lock the position of the lining board, and under the action of the lining board, the lifting strip can be fixed in the circumferential direction, so as to avoid the deviation of the lifting strip. This fixing mode improves the interaction force between the lifting strip and the lining board, and avoids the loosening phenomenon of the lifting strip and the lining board.

[0012] The preferred embodiments of the utility model are described below with reference to the drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the utility model and are not intended to limit the protection scope of the utility model.

[0013] The utility model provides a ball mill is with lining, including cylinder 1, lining 2, lifting strip 3, bolt 4 and nut 5, and lifting strip 3 is fixedly connected with cylinder 1 through bolt 4 and nut 5, and the outer wall of bolt 4 is located between cylinder 1 and nut 5 and is sleeved with sealing ring 9 and metal cover 10, the design of sealing ring 9 and metal cover 10 can avoid the phenomenon that cylinder 1's jack appears the phenomenon of material leakage, and the bottom both sides of lining 2 are pressed tightly with lining 2, and the bottom of lifting strip 3 is provided with two trapezoidal grooves 6, and bolt 4 is configured as trapezoidal bolt 4 that can cooperate with trapezoidal groove 6, and the lug side wall of lining 2 can limit the circumferential direction of lifting strip 3, and the bottom both sides of lifting strip 3 are provided with a plurality of limiting grooves 7, and lining 2 is integrally formed with limiting block 8 that cooperates with limiting groove 7, and the interaction between lifting strip and lining 2 is improved, the side wall of bolt 4 is provided with pressure injection oil cup 11, and the input end of pressure injection oil cup 11 is provided with cup cap 12, and the design can lubricate the connection of nut 5 and bolt 4, and the nut 5 and bolt 4 are convenient to disassemble.

[0014] Working principle: when installing lining and lifting strip, one end of bolt can be placed in trapezoidal groove, then two linings are placed on both sides of the jack of cylinder, then the threaded end of bolt is inserted into the jack of cylinder, then the limiting groove of lifting strip and the limiting block of lining are engaged with each other, then the sealing ring and the metal cover are sleeved on the outer wall of bolt at one time, and finally the nut is locked and fixed, the lifting strip is fixed on the inner wall of cylinder through bolt and nut, and the lining is pressed and fixed, the position of lining is locked through the engagement of limiting groove and limiting block, and the lifting strip is circumferentially fixed under the action of lining, avoiding the deviation of lifting strip, and this fixing mode improves the interaction between lifting strip and lining, avoiding the loosening of lifting strip and lining.
