Abrasive grinding disc tools are the key equipment for crushing materials before they are crushed. Dry or wet grinding of various ores and other grindable materials is possible. Widely used in cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metal dressings and glass ceramics. Abrasive grinding disc tools are suitable for grinding various ores and other materials and are widely used in mineral processing. , building materials and chemical industries. The application of abrasive discs is so extensive that some problems of one kind or another will inevitably occur during the use process. The sudden thickening of the finished product may be a problem that many users have encountered, which causes many factors of thickening of the abrasive grinding disc, and compares complex. Once the finished product is found to be thick, the accident phenomenon should be carefully analyzed to find out the cause of the roughening of the finished product, so as to take timely measures to ensure the quality of the finished product and smooth production.
1. Due to improper installation or poor material, the large and small blades often fall off or break during the operation of the classifier. When the small blades fall off or break, the fineness of the finished product becomes thicker. This situation should be stopped and updated.
2. The coarse powder is washed for a long time, so that the coarse powder return pipe of the mill has holes, so that the coarse powder material leaks into the fine powder area, which leads to the thickening of the finished product. At this time, the hole should be welded in time.
3. The sleeve liner in the abrasive grinding disc is easy to wear due to the impact of materials for a long time. If the replacement is not timely, the inner sleeve will wear and form a hole. When the material entering the classifier passes through the inner sleeve, a part of the material will leak from the hole to the gap between the inner and outer sleeves, and under the action of the circulating wind, enter the fine powder area from bottom to top, causing the finished product to become thick. In this case, stop immediately and repair or update the inner sleeve.
