Polyurethane High Frequency Screen for Mining

Vibrating Screen Mesh is an indispensable part of mobile crushing and screening equipment. It plays an important role in improving the output and quality of crushing and screening during the crushing and screening process. The vibrating screen has the characteristics of simple structure, stable operation, high screening efficiency and large processing capacity. In the vibrating screen, the screen is the main working part to complete the screening process, and it is also the main wearing part.

Polyurethane High Frequency Screen for Mining

Polyurethane High Frequency Screen for Mining will cause confusion and damage the quality of finished products after wear or damage in long-term operation. Improper operation and use will cause the screen to break too quickly . Today, I will share with you the reasons and solutions for the excessive damage of the vibrating screen.

Screen material quality is not enough

If the quality of the screen cannot be reached, it will easily be damaged under the action of high strength, especially when screening large-scale materials such as large stones. If the quality of the screen does not meet the screening requirements of the material, Under high intensity vibration and friction, it is easy to tear or wear.

Solution: The high-manganese steel wire woven screen with high elasticity and wear resistance should be selected, which is not only strong and durable, long life, but also has higher screening efficiency.

Screen plane is not tight enough

If the screen is not tensioned, during the operation of the equipment, high amplitude vibration will cause the screen to vibrate, which usually breaks or is damaged along the edge of the screen or the edge bead. At the same time, the screen is not level enough because the screen is not tensioned. It is easy to deform the screen, and the materials are easy to accumulate at a certain position, causing uneven force on the screen and damage.

Solution: When installing or replacing the screen, 3-4 people should work at the same time, lay the screen on the screen frame, then put the screen compression ring, and use the screws to symmetrically work in accordance with the vertical direction of the screen. Fix, after the screen is unfolded and evenly tightened, thread the screws into the screw holes and slowly tighten them one by one.

Screen pre-tensioning process is poor

The screen generally has an upper sieve layer and a lower force layer. The two layers are required to be in close contact. If the pre-tensioning process of the screen is poor, when the force layer at the bottom of the screen is tightened, the screen is layered. If it is not tightened, then the screen shakes too far when the screen is working, and the contact part with the screen frame cannot be pressed tightly, which is one of the reasons that cause the screen to be damaged too quickly.

Solution: Check the sieving progress of the screen frequently, check whether the screen is compacted, ensure the tension of the screen, reduce the pulsation power of the screen, and ensure that the sieve layer on the upper part of the screen and the force layer on the lower part are closely fitted.

Excessive or uneven feed

In the screening process of the vibrating screen, the width of the vibrating screen determines its processing capacity and the length determines its screening effect. If the feeding amount of the vibrating screen is over the Ambassador's equipment, it cannot be screened. Or the feeding width is not uniform, which causes the material to accumulate, which easily causes the screen to be unevenly stressed and accelerates its damage.
