Then, the curved screen has a bad dehydration effect at work. How to deal with it? 1. The material of the de-intercalation screen is modified, and the feeding mode is changed from the original straight-in type to the overflow type, and the feeding material is fed along the curved screen cutting line. After the transformation, the feeding material is uniformly fed in the width direction of the curved screen, and can be fed into the curved screen strictly according to the tangential direction, so that the effective area of ​​the curved sieve is fully utilized, and the dewatering effect of the curved sieve is greatly improved; 2. Since the size of the screen of the curved screen is the determining factor of the size of the intercepted grain, the management of the screen surface is the key to the production management. When the screen surface is intact, the curved screen should be turned over and turned regularly (usually three Once a month), to ensure that the screen strip on the lower side of the screen has a certain angular angle, thereby improving the effect of desilting and dewatering of the curved screen; 3. Install a large venting hole on the curved screening box to slow down the pressure of the material, so that the material is evenly distributed in the box, and then uniformly fed into the curved screen, thereby reducing the pressure of the material flowing into the curved screen. It avoids the problems caused by the material flow rate being too fast, resulting in poor discharge effect of the curved screen; 4. Add a transverse brace on the curved sieve surface to reduce the flow rate of the material on the curved sieve and increase the movement time; 5. Adjust the angle of the curved screen.
