Analysis of causes of wear and tear
Shelium grinding can generate huge shocks and vibrations in the course of its operation, especially in the ground of the slabs and grinders. In order to prevent the decompression of the slabs and the defoliation of the plate on the grinding board, it is difficult for most enterprises to secure the plate bolts effectively and in a timely manner during the actual production process, at the initial installation, through regular and multiple hardening and pre-rigging bolts. As the equipment operates over a long period of time, the corrosive surface of the equipment and the corrosive edge of the grinding plate and the corrosive edge of the grinding board create a gap, which causes the corrosive face to be hit and, in turn, the corset surface to wear and tear, and further increase the corset。
As a result of the break, the preparation of materials carried by the heated wind exacerbates the brushing of the interface from the edge to the interior. If washed to a certain position, the bolt is bound to lose its strangulation capacity, which, in serious cases, results in the decompression of the skin, damage to the grinder, and even damage to the ground grinder, which in turn breaks the skin. Metal wear and tear of cores and grinders is also a contributing factor to gaps. In the light of the above reasons, it is particularly important to deal effectively with the wear and tear of the core。
Analysis of the vertical wear and tear repair process
1. Traditional review models
Once wear and tear have occurred in the corroding and corroding surfaces, and in the grinding and lining sides, the most common method currently used is to add copper leather to the scene, local welding or offline welding。
However, it has proved difficult to guarantee the life cycle of the equipment by adding copper leather and local welding to the site, with a very high risk of further damage. The reason for this is the inability to ensure a sufficiently effective interface, resulting in the fragmentation of the stress points and the excessive local stress, metal fatigue and further damage; and the long (and usually not less than 15 days) cycle of back-to-work repairs, although relatively high, has a greater impact on production. Also, the combined costs of off-line repairs, which involve the cost of scratching, metal exploration, metal composition analysis, welding and transport of suspensions, are close to hundreds of thousands of dollars and are high。
2. Fukule blue online restoration process
The fussian blue line site rehabilitation model, which has emerged in recent years, is based on the use of high-molecular composite material restoration techniques combined with corresponding components as part of the post-rehabilitation interface, without dismantling the equipment. The chemical bonding force formed after the solidification of the high molecular composite material used for the restoration has enabled it to develop a superior visceralization with the fixed metal component to meet the complex requirements of the operation of the equipment through the high resistance strength of the high molecular composite material. This type of restoration is most important in terms of the combined capacity and value of specialized materials in the form of blue and blue milling。
Fukushi blue online restoration process:
1. Dismantling of grinding skins and processing of the corresponding co-opting surfaces with roasted oil and grinding
2. Surface cleaning with waterless ethanol on the inside of the skin and its core surface
3. 803 demodulants on the inside of the skin and on both sides of the skin and on the side of the plate
4. Refurbishment of materials and coating on the surface of the body, in strict proportion to the bfl
5. Installation of pelts, which are secured by high-strength bolts to ensure that excess materials are squeezed out
When the material is solidified, the gap is measured, while the bolts are tightened on time (8-24-72 hours) in strict compliance with the grinding operation maintenance requirements。

Summary of effects
The technique of protection of milling cores and grinding discs is a good way of preventing and repairing wear and tear problems in advance, filling and resizeing areas of wear and tear using advanced high-molecular composites, and protecting cores of slight wear and tear, which can prevent and resolve the problem of grinding and wear and tear, save clients costs and avoid equipment shutdowns。
