Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-3, in an embodiment of the present utility model, a steel-rubber composite integral liner plate for a ball mill comprises a cylinder liner plate assembly for protecting the interior of a ball mill cylinder and an end liner plate 10 assembly for protecting the inlet and outlet ends of the ball mill;

the barrel lining plate component comprises a lining plate main body 1, the bottom of the lining plate main body 1 is provided with an arc-shaped surface matched with the inner wall of the ball mill barrel, and splicing grooves are formed in two sides of the lining plate main body 1; when in combined installation, each adjacent cylinder liner plate component is aligned by means of splicing at two sides;

the outer wall of the lining plate main body 1 is coated with a rubber framework 2, and two cylinder lifting strips are arranged at the top of the rubber framework 2; the middle part and one side border of the lining plate main body 1 are provided with a plurality of bolt openings 5, the inner walls of the plurality of bolt openings 5 are provided with mounting bolts 6, the lining plate is mounted in the ball mill through the mounting bolts 6, the mounting bolts 6 are locked by utilizing nuts which are arranged outside and matched with the mounting bolts 6, the mounting bolts 6 are countersunk bolts, namely the top surfaces of the mounting bolts 6 are positioned in the bolt openings 5 after the mounting is finished, the impact of materials on the mounting bolts 6 during the work of the ball mill is reduced, the damage of the mounting bolts 6 is reduced, and the service life of the structure is further prolonged; the opposite side fixedly connected with of welt main part 1 installs lug 7, make things convenient for the handling installation of welt through installation lug 7, the barrel promotes the strip and includes support mounting bracket 3, a plurality of mounting groove has been seted up at the middle part of support mounting bracket 3, the equal fixedly connected with wear-resisting piece 4 of inside of a plurality of mounting groove, wear-resisting piece 4 production in-process is vulcanized with rubber skeleton 2 and is combined as an organic wholely, make barrel welt subassembly wholly form the welt of integrated design, its integral erection operation is more convenient than the welt of current split type design, installation work efficiency has been improved greatly, and the structural strength of welt is also higher in the design of integration, fracture and the aversion between the difficult emergence part have prolonged the holistic life of welt.
