Abstract

The utility model discloses a ball mill rubber lining is laid along ball mill barrel axial and circumference by a plurality of lining monomers of unified specification and is formed, lining monomer width direction wholly is the arc, and it includes that welt and even interval set up a plurality of bosses unanimous with ball mill barrel axial on the welt, the welt with boss integrated into one piece be provided with the bolt hole on the boss. The utility model discloses a ball mill rubber lining adopts big width, little length specification, no matter ball mill diameter and length, all adopts the installation of unified specification modularization to reduce because of the different drawback of lining specification of manufacture factory specification, simultaneously, the maintenance is simple swift.

Description

Rubber lining of ball mill

Technical Field

The utility model relates to a ball mill field specifically is a ball mill rubber lining.

Background

The rubber lining of the ball mill is a part which needs to be replaced frequently, and can not only protect the cylinder from abrasion, but also bring the steel balls to a proper height so as to achieve the purpose of optimal grinding effect.

At present, the lining of the barrel of the ceramic ball mill at home and abroad is uniformly distributed according to a plurality of equal parts of the circumference of the barrel, and is determined according to the diameter and the use shape of the barrel. The diameter and the length of the cylinder body of the ball mill are not unified in a standard way, and particularly the common application of the continuous ball mill has different specifications of various manufacturers, so that the rubber lining matched with the ball mill has more specifications of length and width, and is not beneficial to large-scale production.

As shown in figure 1, the existing lining of the ball mill cylinder adopts a button-inserting structure, every row of lining plates 1 are mutually buckled and fixed on the ball mill cylinder 3 through pressing strips 2, when one lining plate has a problem, two adjacent rows of lining plates 1 need to be loosened during maintenance, and the maintenance is extremely inconvenient.

Disclosure of Invention

To the problem that exists among the above-mentioned prior art, the utility model provides a can realize modularization installation, install the convenient ball mill rubber lining of maintenance.

The utility model adopts the technical scheme as follows: the utility model provides a ball mill rubber lining, lays along ball mill barrel axial and circumference by a plurality of lining monomers of unified specification and forms, the whole arc that is of lining monomer width direction, it includes that welt and even interval set up a plurality of and ball mill barrel axial unanimous bosss on the welt, the welt with boss integrated into one piece be provided with the bolt hole on the boss.

Further, the liner monomer has a width greater than a length.

Furthermore, a steel skeleton is embedded at one side of the bolt hole of the lining monomer close to the ball mill cylinder.

Further, the lining monomer is symmetrical in the width direction.

Further, the number of the bosses on the lining single body is 3, and the bosses are respectively arranged in the middle and on two sides.

The beneficial effects of the utility model reside in that:

(1) The uniform length and width specifications are adopted, and the modularized installation is adopted no matter the diameter and the length of the ball mill, so that the defect that the specifications of the linings are different due to different specifications of manufacturers is overcome;

(2) The utility model changes the traditional length-width ratio of the original cylinder rubber lining, the width of the currently adopted lining is smaller, the length is longer, the utility model adopts large width, the length is shortened, the mechanical strength of the product is improved, so as to adapt to the service performance of the large-size ball mill;

(3) The lining of the utility model is a single body which is independently installed, only the lining single body which needs to be maintained needs to be disassembled during maintenance, and the lining single body does not interfere with other adjacent lining single bodies, so that the maintenance is simple and rapid;

(4) The lining monomer structure adopts a symmetrical design, the running direction of the ball mill cylinder body does not need to be considered, the ball mill cylinder body can run forward and backward, and the process adaptability to users is improved;

(5) After the lining single bodies adopt the uniform length and width specification, reasonable inventory can be prepared, and the situation that inventory products cannot meet the installation requirement of the specification of the ball mill is avoided, so that the material supply period is shortened, and the customer requirement is met to the greatest extent.

Detailed Description

To facilitate understanding of the present invention, the present invention will be described more fully and specifically with reference to the accompanying drawings and preferred embodiments, but the scope of the present invention is not limited to the specific embodiments described below.

The rubber lining of the ball mill of the embodiment is formed by laying a plurality of lining single bodies 4 with uniform specifications along the axial direction and the circumferential direction of a ball mill cylinder. As shown in fig. 2-3, the lining single body 4 is arc-shaped in the width direction and has a symmetrical structure in the width direction, and includes a lining plate 401 and a plurality of bosses 402 which are uniformly spaced on the lining plate 401 and are axially consistent with the ball mill barrel, the lining plate 401 and the bosses 402 are integrally formed, bolt holes 403 are formed on the bosses 402, and a steel frame 404 is embedded at one side of the bolt holes 403 of the lining single body 4 close to the ball mill barrel.

In this embodiment, the width of the liner unit 4 is 942mm which is 3 times of pi, and the length thereof is 400mm, the thickness of the liner embedded steel skeleton is 3mm, and the number of the bosses 402 on the liner unit 4 is 3, which are respectively disposed in the middle and at both sides.

During installation, the ball mill cylinder is correspondingly drilled, the lining single bodies 4 are connected with the cylinder through hexagon bolts, and each lining single body 4 is installed one by one along the axial direction and the circumferential direction like paving bricks until the ball mill cylinder is completely paved. If the last row of the ball mill is mounted to the circumferential folding position and the lower integral product cannot be mounted, the liner with the width adjusted can be adopted according to the diameter specification of the ball mill, or the product with the specification is cut to the corresponding size for mounting, and the service performance of the liner is not influenced.

Compared with the prior product structure, the utility model provides high lining mechanical strength, the at utmost has increased effective wearing and tearing work thickness simultaneously.

Many modifications and other embodiments of the invention will come to mind to one skilled in the art to which this invention pertains having the benefit of the teachings presented in the foregoing descriptions and the associated drawings. Therefore, it is to be understood that the inventions are not to be limited to the specific embodiments disclosed and that modifications and other embodiments are intended to be included within the scope of the appended claims. Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.
