Need to be aware of the problems in the process of replacing mesh

It is well-known that mesh needs to be replaced when it was damaged. How to make the screen deck tension when it be replaced, and how to avoid generating resonance when the mesh be used, solving these problems are important factors of normal operation of equipment. this is our summary on the basis of replacing mesh.

Changing mesh is a simple process, but if the user does not pay attention to details, it will lead to a trouble situation that materials don’t move on the screen deck or the material motion trail is disordered when the machine is running.

We analyze the reasons,and take linear vibrating screen as an example. Normal mesh has high degree of tension, there is about 1cm gap to ensure that mesh has a certain vibrating space for avoiding screen plugging when the deck be pulled by hand in the vertical direction. However, the screen deck can not too loose, otherwise, it will generate resonance between screen deck’s vibrating frequency and equipment vibrating frequency, materials will be running in circles on the deck and not discharge. The screen’s installation needs in a certain way.

It needs three people to operating when changing mesh. the screen frame is supported by hard objects on both sides of screen frame firstly, after that, user spread the mesh on the screen frame, the mesh needs to be pressed well by both sides of screen frame. Then, one side of mesh be fixed in the screen frame, meanwhile, please pay attention to reserving a certain size mesh on both sides of screen mesh,avoid the vibrating screen leaving the materials out when running. Next, user tamp down the middle of screen frame, and tighten up the sieve, after fastening the other side of sieve, the hard objects will be removed, mesh will be tightened and straightened by screen frame automatically. Finally, we just need nail down them. Then it can be installed on vibrating screen.When you nail down the sieve, not only has each nail to be fastened up, but also it has the equal distance. When it comes to the last step, it is careful to install to avoid scratching the mesh.

Some type of linear vibrating screen is multi-layer design, and it uses the letter wire frame, there are some bouncing ball to prevent blogging in the screen grid. The larger Wire Diameter should be installed first when user replacing the mesh, thus avoiding thinner sieve damage.
