Description

Technical Field

[0001] The utility model relates to the field of ball mills, in particular to a lining plate for a ball mill. Background Art

[0002] The ball mill is a key equipment for crushing materials after they are crushed. The ball mill is composed of a horizontal ball mill cylinder, a hollow shaft for feeding and discharging materials, and a grinding head. The ball mill cylinder is a long cylinder with grinding bodies inside. The ball mill cylinder is made of steel plates and is fixed to the cylinder by steel linings. The grinding bodies are generally steel balls and are loaded into the cylinder according to different diameters and a certain proportion. The grinding bodies can also be steel segments. The materials are selected according to the particle size of the grinding materials. The materials are loaded into the ball mill cylinder from the hollow shaft at the feeding end of the ball mill. When the ball mill cylinder rotates, the grinding bodies are attached to the lining of the ball mill cylinder due to inertia, centrifugal force, and friction, and are carried away by the ball mill cylinder. When they are brought to a certain height, they are thrown down due to their own gravity. The falling grinding bodies crush the materials in the ball mill cylinder like projectiles.

[0003] In the prior art, the ball mill liner is generally fixed to the inner side of the ball mill cylinder by bolts, which is not only inconvenient to disassemble and maintain, but also the bolts are prone to loosening, thereby affecting product quality.

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] like Figure 1-7As shown, a ball mill liner comprises a ball mill cylinder 1 and a plurality of liner plates 2 arranged on the inner side of the ball mill cylinder 1. The liner plates 2 are detachably arranged on the inner side of the ball mill cylinder 1 through a fixing mechanism. The fixing mechanism comprises a fixing plate 3 spaced apart from the liner plates 2. Positioning recesses 10 are symmetrically arranged at the bottom of both ends of the fixing plate 3. A fixing base plate 7 is integrally formed at the bottom of the liner plate 2. Both the fixing base plate 7 and the fixing plate 3 are arc-shaped plates adapted to the inner wall of the ball mill cylinder 1. The ends of the fixing base plate 7 correspond to and fit with the positioning recesses 10. The ends of the fixing base plate 7 are plugged into the positioning recesses 10. The top ends of the fixing base plate 7 are symmetrically provided with card grooves 9. The top of the inner side of the positioning recess 10 is provided with an installation recess 11. The inner lower end of the installation recess 11 is movably connected with a card plate 13 adapted to the card groove 9. The bottom of the card plate 13 is evenly provided with oblique teeth 14, and the downward side of the oblique teeth 14 is an inclined surface. An adjusting plate 12 is movably provided at the inner upper end of the mounting groove 11, and a first spring 16 is provided between the adjusting plate 12 and the card plate 13. The four corners of the adjusting plate 12 are symmetrically and movably connected with T-shaped pins 15, and the bottom of the T-shaped pin 15 is fixedly connected to the top of the card plate 13. The first spring 16 is sleeved on the outer side of the T-shaped pin 15, and the lower end of the card plate 13 protrudes from the inner wall of the positioning recess 10, and the protruding part is engaged with the card groove 9, and the first spring 16 is in a contracted state when engaged. The corresponding part of the top of the fixing plate 3 and the mounting groove 11 is threadedly engaged with an adjusting bolt 8 corresponding to the adjusting plate 12, and the lower end of the adjusting bolt 8 extends to the inner side of the mounting groove 11 and is rotatably connected to the top of the adjusting plate 12.

[0029] Furthermore, the fixing plate 3 is fixed to the inner side of the ball mill cylinder 1 by a locking assembly. The locking assembly includes second threaded holes 6 uniformly arranged along the circumference of the ball mill cylinder 1. The second threaded holes 6 are multiple groups. The multiple groups of second threaded holes 6 correspond one-to-one to the multiple fixing plates 3. The number of second threaded holes 6 in each group is at least two. The bottom of the fixing plate 3 is provided with a first threaded hole 5 corresponding to the second threaded hole 6. The second threaded hole 6 is provided with a fixing bolt 4, and one end of the fixing bolt 4 is threadedly connected to the first threaded hole 5.

[0030] In order to ensure the stability of the lifting and lowering fixing bolt 4 , a second spring 17 is provided inside the first threaded hole 5 to abut against the fixing bolt 4 .

[0031] It should be noted that the utility model is a ball mill liner. When in use, the first threaded hole 5 at the bottom of the fixing plate 3 is matched with the second threaded hole 6 on the ball mill cylinder 1, and then the fixing bolt 4 is screwed in. The end of the fixing bolt 4 contacts the second spring 17, and then the second spring 17 is compressed and deformed. The second spring 17 generates a reverse force to act on the fixing bolt 4, reducing the possibility of loosening of the fixing bolt 4. Then, the end of the fixing base plate 7 at the bottom of the liner 2 is aligned with the positioning recess 10 at the bottom end of the adjacent fixing plate 3, and then the liner 2 is pushed into between the adjacent fixing plates 3, and the end of the fixing base plate 7 enters the positioning recess 10, and the fixing base The end of the plate 7 is squeezed with the bevel teeth 14 at the bottom of the card plate 13, and the card plate 13 will cooperate with the adjusting plate 12 to compress the first spring 16 upward. Since the bottom of the bevel teeth 14 is a slope, the bevel teeth 14 will continue to be stuck in the card slot 9. When the bevel teeth 14 at the bottom of the card plate 13 are completely stuck in the card slot 9, they are fixed, and at this time the first spring 16 is still in a contracted state. When disassembly is required, it is only necessary to screw the adjusting bolt 8 to drive the adjusting plate 12 to move upward. The adjusting plate 12 drives the card plate 13 to move upward through the T-pin 15 until the bevel teeth 14 are completely hidden in the mounting groove 11. Finally, the lining plate 2 and the fixed base plate 7 as a whole can be pushed out from between the adjacent fixed plates 3.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
