Due to the long-term use of polyurethane screens without good protection, a series of problems will occur, and excessive damage is also one of the failures. This phenomenon should be considered whether it is caused by quality problems or other reasons. We analyze below a bit:
① The tension of the polyurethane sieve plate is not enough, which causes the polyurethane sieve plate to vibrate, which usually breaks or is damaged along the edge of the polyurethane sieve plate or the edge bead. Always check the tension of the polyurethane sieve, and check whether the polyurethane sieve is installed firmly.
② The problem of feeding materials. Because the continuous feeding during the vibrating screen work, but if too much feeding at one time, the normal movement of the material on the screen surface will be hindered, which will not only easily loosen the fatigue of the polyurethane sieve plate, but also greatly reduce the material handling capacity.
③ Giving a large amount of material at one time will suddenly increase the load of the motor that is in unbalanced operation, not only easy to damage the polyurethane screen, but also easy to cause damage to the vibration motor, so you must uniformly feed the material.
④ In the feeding mode with strong impact force, it is necessary to add a buffer hopper to the polyurethane sieve in the vibrating screen. The direct impact of the material on the polyurethane sieve plate will consume the excitation force generated by the vibration source, and it is more likely to cause the polyurethane sieve to be damaged and screen Net fatigue.
⑤ The quality of the polyurethane screen is an important factor that causes the polyurethane screen to break too quickly. If the material of the polyurethane sieve sheet fails to meet the screening requirements of the material, the polyurethane sieve will be damaged quickly.
The strong impact feeding method caused the polyurethane screen to break too quickly. It is necessary to install a buffer hopper for the polyurethane sieve in the vibrating screen. The direct impact of the material on the polyurethane sieve plate will consume the excitation force generated by the vibration source, which will easily cause damage to the polyurethane sieve and the screen fatigue.
Giving a large amount of material at one time caused the polyurethane screen to break too quickly. This will suddenly increase the load of the motor that is in unbalanced operation, not only easy to damage the polyurethane screen, but also easy to cause damage to the vibration motor, so it is necessary to evenly feed the material.
The problem of material feeding caused the polyurethane screen to break too quickly. Because the continuous feeding during the vibrating screen work, but if too much feeding at one time, the normal movement of the material on the screen surface will be hindered, which will not only easily loosen the fatigue of the polyurethane sieve plate, but also greatly reduce the material handling capacity.
Insufficient tension of the polyurethane sieve plate causes the polyurethane sieve plate to break too quickly. Always check the tension of the polyurethane sieve, and check whether the polyurethane sieve is installed firmly.
When choosing a polyurethane sieve plate, you need to look at its appearance, whether it is exquisite in appearance, whether the sieve plate is flat, whether the hue of the sieve plate is simple, whether there are broken bars, burrs, lack of material, mixing, dense seams and other appearances. Appearance is a prerequisite to guarantee its service life.
The above is the reason why the polyurethane sieve plate that Jiding Environmental Protection Technology Company introduced to you is prone to breakage too quickly. For more questions about polyurethane sieve plate, please refer to other content on this site, or call for detailed inquiry.
