本発明は、粉砕用ミル、粉粒体供給器等の産業機械、器
具、装置に適用するライニング材に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lining material applied to industrial machines, instruments, and devices such as grinding mills and powder feeders.
粉砕用ミル、粉粒体供給器等の機械器具には、粉砕又は
混練用ボールや粉体等の材料から壁面を保護するための
ゴムライニングが取り付けられているが、一般にこのゴ
ムライニングは摩耗が激しく、また大きな衝撃を受ける
ことから衝撃吸収性並びに衝撃に対する取付部の安定性
に優れていることが要求される。Rubber linings are attached to mechanical equipment such as grinding mills and powder feeders to protect the walls from grinding or kneading balls and materials such as powder, but generally this rubber lining is subject to wear. Since it is subject to severe and large impacts, it is required that the mounting portion has excellent shock absorption properties and stability against impacts.
しかしながら、衝撃吸収性は弾性度が高い場合に良好な

るため、取付部が破損し易いという欠点がある。However, while shock absorption is good when the elasticity is high, mounting stability is improved when the elasticity is low, that is, as the rigidity increases. For example, as shown in FIG. 9, it was difficult to achieve both, for example, a lifter e in which a hollow part d is formed in the bottom of the rubber body al into which a fitting c to be fitted to the wall b is inserted.
In case l, the entire lining material is made of rubber and has high elasticity, so it has a large impact absorption capacity and excellent wear resistance. ), stress is concentrated around the hollow part, which has the disadvantage that the mounting part is easily damaged.

も必ずしも充分でないという憾みがある。In addition, as shown in FIG. 10, a metal plate g is fixed to the bottom of the rotating wall b, and a metal plate g is attached to the entire bottom of the rubber body a2.
Lifter e2, in which a mounting bracket c is attached to the metal body by baking and bonding, has also been used in the past, but its low elasticity results in poor shock absorption and inferior wear resistance compared to the example shown in Figure 9. Although the rubber body A2 has excellent installation stability, stress is concentrated at the adhesive interface between the rubber body A2, which is an elastic body, and the metal plate g, which is a rigid body, due to repeated impact forces.
may peel off from the metal plate g, and there is a problem that the mounting stability is not necessarily sufficient.

きるようにしようとするものである。In view of the above, the present invention provides a rubber lining material that is fastened to a wall using a fastening metal fitting having a support rod and a locking piece projecting laterally at the tip of the support rod. A high-tension, low-stretch member surrounds the hollow part along a restraining surface on the inner periphery of the hollow part that is pressed toward the wall by the locking piece, and a non-restricting surface extending above the locking piece from this restraining surface. By embedding a flexible material of 100% and adjusting the elasticity around the hollow part, it is possible to improve the stability of attaching the lining material to the wall, while also adjusting the shock absorption properties as desired. It is intended to be configurable.

In the lifter 1a of the present invention, the flexible member 14a restricts the elongation deformation of the unrestricted surface 2b and its surroundings.In other words, the flexible member 14a controls the elasticity around the hollow portion according to its elongation characteristics. The hollow portion is lowered lower than the Hijikata rubber portion 13 to provide a shape-retaining effect to the lifter 1a. Therefore, in the lifter 1a of the present invention, compared to the all-rubber type lifter e1, the strain amount of the lifter is smaller to the extent that it does not impair the shock absorbing properties described later, and the strain is reduced near the base of the restraint part (indicated by reference numeral 15) or The occurrence of cracks, etc. at the rising portion 17 is prevented, and the installation stability is increased. In addition, as shown in Fig. 10, the lifter E2 is a metal plate baking type in which an aluminum alloy metal plate g with an average wall thickness of 1071111 mm is baked and bonded to the rubber body A2, and the rubber body A2 is firmly attached to the rigid metal plate g. The rubber body A2 is bonded and there is no deformation of the hollow part d.
The amount of distortion is very small compared to the lifter according to the present invention.

It is understood that the strain characteristics can be arbitrarily set by adjusting the type and quantity of the flexible material. Incidentally, in the graph of Fig. 11, R is the amount of strain due to the elasticity of the rubber body, and R is the amount of strain due to deformation of the hollow part d in the all-rubber type.
U represents the amount of strain due to deformation of the hollow portion 2 when the flexible material 14a is buried, and T represents the difference in the amount of strain due to the presence or absence of the flexible material, that is, the degree of decrease in elasticity.

られる。It is known that this strain acceleration has a correlation with energy absorption ability, and the smaller the strain acceleration, the greater the energy absorption ability. According to the graph, the strain acceleration at the same energy level is the highest for the metal plate baking type lifter E2. The lifter 1a according to the present invention includes:
Similar to the all-rubber type lifter e1, the strain acceleration is a small value, indicating that it has excellent shock absorption ability. In addition, FIG. 14 shows each lifter 1a, e1, e.
This is to compare the abrasion resistance of 2. As a grinding mill, the diameter is 2200? , length 5000? Rotating wall body and diameter 90?

In the test, a lifter with dimensions of width 165,711!11 and height of 135 meters and a hardness of the rubber body of 601 Hs was used, and a hard sandstone with the dimensions shown in Table 2, specific gravity of 2.68, and number of work losses was used. 15 tons of 1410KWH/S-TON are supplied per hour and pulverized to an average diameter of 200μ or less. The rotation speed of the grinding mill is 21r. p. m
.. (73.5% Cs). As can be seen from the graph in FIG. 14, the wear amount of the lifter 1a according to the present invention is:
The wear resistance is comparable to that of the all-rubber type lifter e1, and is much better than the metal plate baked-on type lifter E2. The material and number of flexible members 14a are as follows:
The selection is made depending on the magnitude of the impact energy that the lifter receives, but for example, a rotating wall with a diameter of 30001111 and a diameter of 90? In a mill that uses crushing rods of A lifter with excellent properties can be obtained.
