DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION

As shown in fig. 1 and 2, a combined mill liner plate comprises a nylon liner plate 1, beads 2 and a connecting piece 3, wherein the surface of the nylon liner plate 1 is connected with a plurality of beads 2 which are arranged at intervals through the connecting piece 3, the beads 2 are strip-shaped and are arranged in parallel, the intervals between the adjacent beads 2 are equal, the beads 2 comprise three layers from outside to inside, the layers are a wear-resistant layer 301, a metal body 302 and a filling body 303 in sequence, and the upper end surface of each bead 2 is wave-shaped or zigzag; the upper end of the nylon lining plate 1 corresponds to the mounting groove 101 with a long strip shape formed by the pressing strip 2, the lower end of the pressing strip 2 corresponds to and is inserted into the mounting groove 101, the metal body 302 is provided with a T-shaped through groove along the length direction, the T-shaped through groove comprises a transverse groove 304 penetrating through two end faces of the metal body 302 and a vertical groove 305 communicating the lower end face of the metal body 302 with the transverse groove 304, the filler 303 is arranged in the transverse groove 304, the lower end face of the filler 303 is provided with a groove 306 communicating with the vertical groove 305, the connecting piece 3 is a T-shaped bolt, the head of the T-shaped bolt is arranged in the groove 306, the threaded end of the T-shaped bolt penetrates through the vertical groove 305 and a through hole correspondingly formed in the nylon lining plate 1 and extends out to the lower side of the nylon lining plate 1 and is connected with a nut, the pressing strip 2 is mounted on the nylon.

The wear-resistant layer 301 is made of a bimetal multi-layer wear-resistant steel plate; the nylon lining plate 1 is made of modified monomer casting nylon.

The combined mill lining plate has the following advantages:

1. compared with a metal lining plate, the nylon lining plate 1 can save metal materials, and on the other hand, because the self mass is small, the energy required by the ball mill to drive the ball mill to rotate is small, so that the energy consumption is low, and the use cost is low.

2. The nylon material has higher tensile strength and compressive strength; the fatigue resistance is outstanding, and the original mechanical strength of the product can be still maintained after the product is repeatedly bent and folded for many times; the surface is smooth, and the friction coefficient is small, so that the wear resistance is higher; the nylon lining plate 1 is corrosion-resistant, alkali-resistant, and resistant to most of salt solution, weak acid and engine oil, so that the nylon lining plate 1 made of the nylon material has more excellent mechanical property and chemical property and long service life.

3. The nylon material is strong to the absorption capacity of impact, stress vibration, thereby nylon welt 1 is little at the during operation noise, and the obturator 303 of nylon material, make layering 2 noise also little at the during operation, nylon obturator 303 can play better supporting role to metal body 302 on the one hand, and can play energy-absorbing shock-absorbing effect at layering 2 during operation, thereby layering 2 vibration at the during operation is little, layering 2 is also more firm with being difficult to the pine take off with being connected of nylon welt 1, thereby this kind of combined mill welt has better mechanical properties.

4. The wear-resistant layer 301 can play effectual wearing and tearing protection to metal body 302, increases metal body 302's wearability for layering 2 long service life, and metal body 302 has higher hardness, thereby can play better supplementary grinding's effect to the material.

5. The wavy or zigzag surface of the pressing strip 2 plays an auxiliary promoting role in crushing the materials.

The above-mentioned connected mode, the connected mode of setting, installation can select suitable connected mode among the prior art that has existed, like welding, riveting, threaded connection, bonding, pin joint, key-type connection, elastic deformation connect, buckle connection, interference connection, injection moulding's mode realization structural linking to each other, in the actual production, should realize connecting the purpose, guarantee under the prerequisite of connection effect, according to production condition, select the connected mode that the cost is lower, production efficiency is high.
